::stage Baby :: Baby whales are called calves. The gestation period in most whale species is 11 to 16 months. Generally a single young is born, tail first likely in order to prevent drowning, and twins are very rare. The newborn calf is usually one-quarter to a third the length of the mother. The baby stage runs from birth until the calf is weaned, during which time the calf frequently nurses on the mother's nutrient rich milk. Baleen whales will wean their calves by their first summer when they are less than a year old, while toothed whales take up to three years to be completely weaned. Calves grow very rapidly, thanks to the extremely high proportion of fat and proteins contained in whale milk. ::stage Adolescent :: The adolescent or juvenile stage runs from the moment the calf is weaned to when it reaches sexual maturity. Again, this varies according to the species.Once weaned, juveniles start to mix with whales of the same age and gender. Male juvenile whales will form bachelor pods and leave their original pod. They will start searching for sexually mature cows, female whales, with whom to mate. Female juveniles also start exploring outside their pod, but they are more likely to return to their matriarchal pod or to their mother. ::stage Adult :: The adult whale stage starts when the whale reaches sexual maturity. This can occur between the ages of six and 13 years, varying dramatically depending on the species. Breeding often takes place seasonally in migrating species but in others it seems to occur through most of the year. In the adult stage, whales of both genders start searching for mates with whom to breed. Sexually mature whales migrate to warmer waters during winter to mate. This ensures that when adults return the next year, their calves will be born in more temperate conditions. Mating takes place every two to three years for the cow as her gestation period lasts for between 10 and 14 months. Some whales, like humpbacks can theoretically produce one calf each year, with a gestation period of 11-12 months, but this rarely ever happens as it would strain the mother too much to calve every year.

The baby stage runs from birth until the calf is weaned, during which time the calf frequently nurses on the mother's nutrient rich milk. Baleen whales will wean their calves by their first summer when they are less than a year old, while toothed whales take up to three years to be completely weaned. Calves grow very rapidly, thanks to the extremely high proportion of fat and proteins contained in whale milk. ::stage Adolescent :: The adolescent or juvenile stage runs from the moment the calf is weaned to when it reaches sexual maturity. Again, this varies according to the species.Once weaned, juveniles start to mix with whales of the same age and gender. Male juvenile whales will form bachelor pods and leave their original pod. They will start searching for sexually mature cows, female whales, with whom to mate. Female juveniles also start exploring outside their pod, but they are more likely to return to their matriarchal pod or to their mother. ::stage Adult :: The adult whale stage starts when the whale reaches sexual maturity. This can occur between the ages of six and 13 years, varying dramatically depending on the species. Breeding often takes place seasonally in migrating species but in others it seems to occur through most of the year. In the adult stage, whales of both genders start searching for mates with whom to breed. Sexually mature whales migrate to warmer waters during winter to mate. This ensures that when adults return the next year, their calves will be born in more temperate conditions. Mating takes place every two to three years for the cow as her gestation period lasts for between 10 and 14 months. Some whales, like humpbacks can theoretically produce one calf each year, with a gestation period of 11-12 months, but this rarely ever happens as it would strain the mother too much to calve every year.

Baleen whales will wean their calves by their first summer when they are less than a year old, while toothed whales take up to three years to be completely weaned. Calves grow very rapidly, thanks to the extremely high proportion of fat and proteins contained in whale milk. ::stage Adolescent :: The adolescent or juvenile stage runs from the moment the calf is weaned to when it reaches sexual maturity. Again, this varies according to the species.Once weaned, juveniles start to mix with whales of the same age and gender. Male juvenile whales will form bachelor pods and leave their original pod. They will start searching for sexually mature cows, female whales, with whom to mate. Female juveniles also start exploring outside their pod, but they are more likely to return to their matriarchal pod or to their mother. ::stage Adult :: The adult whale stage starts when the whale reaches sexual maturity. This can occur between the ages of six and 13 years, varying dramatically depending on the species. Breeding often takes place seasonally in migrating species but in others it seems to occur through most of the year. In the adult stage, whales of both genders start searching for mates with whom to breed. Sexually mature whales migrate to warmer waters during winter to mate. This ensures that when adults return the next year, their calves will be born in more temperate conditions. Mating takes place every two to three years for the cow as her gestation period lasts for between 10 and 14 months. Some whales, like humpbacks can theoretically produce one calf each year, with a gestation period of 11-12 months, but this rarely ever happens as it would strain the mother too much to calve every year.

::stage Egg:: Newt eggs are encased in a gel-like substance rather than a hard shell. Adult females release eggs one at a time and store them in clusters ranging from a handful to several dozen in size. Adults often take an active role in defending their eggs after depositing them. Mothers may curl their body around the eggs to provide protection. Some newt species even wrap leaves around each egg individually to camouflage them, according to San Diego Zoo. Newt eggs are small: some measure only a millimeter or two in diameter. Mom usually anchors her eggs to underwater plants and other structures to keep them safe. ::stage Tadpole:: Newts that hatch from submerged eggs usually emerge as aquatic larvae with fishlike tails and gills that allow them to breathe beneath the water's surface. Not all newt species have an aquatic or 'tadpole' phase. This tadpole stage tends to be short, except in fully aquatic species. Eastern newt (Notophthalmus viridescens) larvae spend only a few months as tadpoles, but they remain in the terrestrial larval stage for years before fully maturing, according to Island Creek Elementary School. Some newts spend their entire juvenile life as tadpoles and never go through a terrestrial stage. ::stage Eft:: Many newts progress to a terrestrial larval stage following their brief time as a tadpole. They are called 'efts' at this point in their life cycle. Even newts that are aquatic as eggs and adults may spend several years on land as an eft between the two stages. The land-bound juveniles are still amphibious, so they require environments with shade and moisture. The efts tend to hide under stones, logs, fallen leaves and other forms of natural shelter in environments with damp soil, according to the New Hampshire Fish and Game Department. ::stage Adult:: Adult newts are versatile. Most have both legs and wide tails, so the adults can walk on land or swim in the water. However, individual species show a propensity for either terrestrial or aquatic environments and spend most of their time in one of them. The smooth newt (Lissotriton vulgaris) spends most of its adult life on land, but courtship and mating occur exclusively in aquatic environments during the appropriate season, according to the Online Field Guide.

::stage seed:: Think about which came first - the tree, or the seed? Regardless of what you believe, the more you learn about them, trees are simply amazing. Seeds come in a wide variety of shapes, weights, colors, and sizes, depending on the species. All seeds develop from male and female parts of the trees producing fruits but not all of them are easily recognizable or edible. Some seeds are contained in a protective nut like an acorn, pecan, or hickory. Other seeds are found in fleshy fruits, like the black cherry, mulberry, or persimmon. The fruit of a pine is a cone and the seed is winged and resembles a miniature helicopter when falling in the wind from an open pinecone. Wind, water, animals, and people disperse seeds to a wide range of landscapes including the forest floor, open fields, yards, rocky slopes, and roadsides. Anywhere the conditions are favorable for germination, seeds will sprout and grow. ::stage sprout:: An embryo is within each seed, but not all seeds will germinate. Favorable environmental conditions enable the embryo to grow, expand, and break through the seed coat using the stored food supply of the seed for the necessary energy to grow. The root grows downward to the soil to anchor the sprout and search for water and nutrients, while the sprout emerges from the ground seeking sunlight. Ideally, the sprout will find light and then the leaves, needles, or scales will develop further to allow the tree to make its own food through photosynthesis. ::stage seedling:: The sprout persistently grows and begins to develop woody characteristics. The soft green stem begins to harden, change color, and develop a thin protective bark. Leaves or needles develop and continue to search out light. The root grows and branches down and out resembling an upside down underground tree with a flattened top. The majority of the tree's roots are in the upper portions of soil to absorb available water and nutrients but also to breathe. Like us, tree roots need oxygen or they will die. The seedling must compete with other trees and plants for its share of nutrients, water, sunlight, and space. Other threats include fire, flood, drought, ice and snow, disease, insect attacks, and the threat of being consumed by animals. At this seedling stage, the tree is most susceptible to being killed. If it can survive these early years without harm, the seedling is well on its way to the next phase in the cycle. ::stage Sapling:: A sapling is a small tree usually between 1 and 4 inches in diameter at 4.5 feet. This is the standard height where a tree's diameter is measured - diameter at breast height (DBH). Typically, a sapling is the size of a tree that is growing in a commercial nursery for transplanting to your yard. In this juvenile state, the tree is not mature enough to reproduce. However, the sapling is growing rapidly. The sapling encounters similar types of competition and threats to that of a seedling. ::stage Mature:: With favorable conditions, a sapling will continue to develop into a mature tree. During this mature stage in the cycle, each tree will grow as much as its species and site conditions will permit. In addition, flowers develop, reproduction ensues, fruits form, and seed dispersal can now occur. The optimum time to harvest trees for forest products beneficial to people is during this stage in the lifecycle. In Texas, the majority of products are made from southern yellow pine (loblolly, longleaf, shortleaf, and slash). Hardwoods such as ash, hickory, mesquite, pecan, and oak are also used but southern yellow pine is the main commercially grown species to meet public demand for wood products such as those listed below. A few of the products made from Texas trees include: paper, dimensional lumber, cabinets, molding, doors, pallets, boxes, crates, trusses, fireplace mantels, furniture, oriented strand board (OSB), flooring, crossties, joists, decking, log homes, posts, poles, cooking wood, fencing, fuel, interior finishing, pilings, bridges, animal bedding, mulch, heavy construction timbers, charcoal, shingles, and many more. If a tree is never harvested, over the course of time it continues to provide many other benefits, but eventually will begin to decline. ::stage Decline:: At this point, the tree's survival is determined more by external stresses rather than the tree's vigor. These stresses take a toll on the tree making it more susceptible to insects and diseases, and it eventually succumbs to a causal agent or the pressures of competition from other more vigorously growing plants adjacent to the tree. The end result is no surprise. ::stage Snag:: The life span of a tree is as wide-ranging as the number of tree varieties, yet death is inevitable. Usually it is a combination of factors that finally overcome a tree and cause it to die. Injury, drought stress, followed by disease, rot, root dieback, coupled with a lightning strike and insect infestation is just one of many scenarios. However, sometimes it can be just one factor serious enough to cause mortality. Yet, the cycle does not end here. A standing dead tree, also called a snag, still plays a vital role in the life cycle. Decomposition takes time. A snag slowly breaks down and returns nutrients to the soil as small limbs, bark, and branches fall to the ground. The snag also provides habitat, cover, and food for wildlife and insects. In turn, animals, insects, and fungi help break down the tree. Eventually, the snag will fall to the ground and gradually return nutrients to the soil where they are taken up again by other trees by providing for their growth. And, the cycle begins anew. | a sprout does not have develop protective bark | entailment | difference |
::stage seed:: Think about which came first - the tree, or the seed? Regardless of what you believe, the more you learn about them, trees are simply amazing. Seeds come in a wide variety of shapes, weights, colors, and sizes, depending on the species. All seeds develop from male and female parts of the trees producing fruits but not all of them are easily recognizable or edible. Some seeds are contained in a protective nut like an acorn, pecan, or hickory. Other seeds are found in fleshy fruits, like the black cherry, mulberry, or persimmon. The fruit of a pine is a cone and the seed is winged and resembles a miniature helicopter when falling in the wind from an open pinecone. Wind, water, animals, and people disperse seeds to a wide range of landscapes including the forest floor, open fields, yards, rocky slopes, and roadsides.

A few of the products made from Texas trees include: paper, dimensional lumber, cabinets, molding, doors, pallets, boxes, crates, trusses, fireplace mantels, furniture, oriented strand board (OSB), flooring, crossties, joists, decking, log homes, posts, poles, cooking wood, fencing, fuel, interior finishing, pilings, bridges, animal bedding, mulch, heavy construction timbers, charcoal, shingles, and many more. If a tree is never harvested, over the course of time it continues to provide many other benefits, but eventually will begin to decline. ::stage Decline:: At this point, the tree's survival is determined more by external stresses rather than the tree's vigor. These stresses take a toll on the tree making it more susceptible to insects and diseases, and it eventually succumbs to a causal agent or the pressures of competition from other more vigorously growing plants adjacent to the tree. The end result is no surprise. ::stage Snag:: The life span of a tree is as wide-ranging as the number of tree varieties, yet death is inevitable. Usually it is a combination of factors that finally overcome a tree and cause it to die. Injury, drought stress, followed by disease, rot, root dieback, coupled with a lightning strike and insect infestation is just one of many scenarios. However, sometimes it can be just one factor serious enough to cause mortality. Yet, the cycle does not end here. A standing dead tree, also called a snag, still plays a vital role in the life cycle. Decomposition takes time. A snag slowly breaks down and returns nutrients to the soil as small limbs, bark, and branches fall to the ground. The snag also provides habitat, cover, and food for wildlife and insects. In turn, animals, insects, and fungi help break down the tree. Eventually, the snag will fall to the ground and gradually return nutrients to the soil where they are taken up again by other trees by providing for their growth. And, the cycle begins anew. | mature have the ability to absorb nutrients from the soil | entailment | difference |
::stage seed:: Think about which came first - the tree, or the seed? Regardless of what you believe, the more you learn about them, trees are simply amazing. Seeds come in a wide variety of shapes, weights, colors, and sizes, depending on the species. All seeds develop from male and female parts of the trees producing fruits but not all of them are easily recognizable or edible. Some seeds are contained in a protective nut like an acorn, pecan, or hickory. Other seeds are found in fleshy fruits, like the black cherry, mulberry, or persimmon. The fruit of a pine is a cone and the seed is winged and resembles a miniature helicopter when falling in the wind from an open pinecone. Wind, water, animals, and people disperse seeds to a wide range of landscapes including the forest floor, open fields, yards, rocky slopes, and roadsides. Anywhere the conditions are favorable for germination, seeds will sprout and grow. ::stage sprout:: An embryo is within each seed, but not all seeds will germinate. Favorable environmental conditions enable the embryo to grow, expand, and break through the seed coat using the stored food supply of the seed for the necessary energy to grow. The root grows downward to the soil to anchor the sprout and search for water and nutrients, while the sprout emerges from the ground seeking sunlight. Ideally, the sprout will find light and then the leaves, needles, or scales will develop further to allow the tree to make its own food through photosynthesis. ::stage seedling:: The sprout persistently grows and begins to develop woody characteristics. The soft green stem begins to harden, change color, and develop a thin protective bark. Leaves or needles develop and continue to search out light. The root grows and branches down and out resembling an upside down underground tree with a flattened top. The majority of the tree's roots are in the upper portions of soil to absorb available water and nutrients but also to breathe. Like us, tree roots need oxygen or they will die. The seedling must compete with other trees and plants for its share of nutrients, water, sunlight, and space. Other threats include fire, flood, drought, ice and snow, disease, insect attacks, and the threat of being consumed by animals. At this seedling stage, the tree is most susceptible to being killed. If it can survive these early years without harm, the seedling is well on its way to the next phase in the cycle. ::stage Sapling:: A sapling is a small tree usually between 1 and 4 inches in diameter at 4.5 feet. This is the standard height where a tree's diameter is measured - diameter at breast height (DBH). Typically, a sapling is the size of a tree that is growing in a commercial nursery for transplanting to your yard. In this juvenile state, the tree is not mature enough to reproduce. However, the sapling is growing rapidly. The sapling encounters similar types of competition and threats to that of a seedling. ::stage Mature:: With favorable conditions, a sapling will continue to develop into a mature tree. During this mature stage in the cycle, each tree will grow as much as its species and site conditions will permit. In addition, flowers develop, reproduction ensues, fruits form, and seed dispersal can now occur. The optimum time to harvest trees for forest products beneficial to people is during this stage in the lifecycle.

The fruit of a pine is a cone and the seed is winged and resembles a miniature helicopter when falling in the wind from an open pinecone. Wind, water, animals, and people disperse seeds to a wide range of landscapes including the forest floor, open fields, yards, rocky slopes, and roadsides. Anywhere the conditions are favorable for germination, seeds will sprout and grow. ::stage sprout:: An embryo is within each seed, but not all seeds will germinate. Favorable environmental conditions enable the embryo to grow, expand, and break through the seed coat using the stored food supply of the seed for the necessary energy to grow. The root grows downward to the soil to anchor the sprout and search for water and nutrients, while the sprout emerges from the ground seeking sunlight. Ideally, the sprout will find light and then the leaves, needles, or scales will develop further to allow the tree to make its own food through photosynthesis. ::stage seedling:: The sprout persistently grows and begins to develop woody characteristics. The soft green stem begins to harden, change color, and develop a thin protective bark. Leaves or needles develop and continue to search out light. The root grows and branches down and out resembling an upside down underground tree with a flattened top. The majority of the tree's roots are in the upper portions of soil to absorb available water and nutrients but also to breathe. Like us, tree roots need oxygen or they will die. The seedling must compete with other trees and plants for its share of nutrients, water, sunlight, and space. Other threats include fire, flood, drought, ice and snow, disease, insect attacks, and the threat of being consumed by animals. At this seedling stage, the tree is most susceptible to being killed. If it can survive these early years without harm, the seedling is well on its way to the next phase in the cycle. ::stage Sapling:: A sapling is a small tree usually between 1 and 4 inches in diameter at 4.5 feet. This is the standard height where a tree's diameter is measured - diameter at breast height (DBH). Typically, a sapling is the size of a tree that is growing in a commercial nursery for transplanting to your yard. In this juvenile state, the tree is not mature enough to reproduce. However, the sapling is growing rapidly. The sapling encounters similar types of competition and threats to that of a seedling. ::stage Mature:: With favorable conditions, a sapling will continue to develop into a mature tree. During this mature stage in the cycle, each tree will grow as much as its species and site conditions will permit. In addition, flowers develop, reproduction ensues, fruits form, and seed dispersal can now occur. The optimum time to harvest trees for forest products beneficial to people is during this stage in the lifecycle. In Texas, the majority of products are made from southern yellow pine (loblolly, longleaf, shortleaf, and slash). Hardwoods such as ash, hickory, mesquite, pecan, and oak are also used but southern yellow pine is the main commercially grown species to meet public demand for wood products such as those listed below. A few of the products made from Texas trees include: paper, dimensional lumber, cabinets, molding, doors, pallets, boxes, crates, trusses, fireplace mantels, furniture, oriented strand board (OSB), flooring, crossties, joists, decking, log homes, posts, poles, cooking wood, fencing, fuel, interior finishing, pilings, bridges, animal bedding, mulch, heavy construction timbers, charcoal, shingles, and many more. If a tree is never harvested, over the course of time it continues to provide many other benefits, but eventually will begin to decline. ::stage Decline:: At this point, the tree's survival is determined more by external stresses rather than the tree's vigor. These stresses take a toll on the tree making it more susceptible to insects and diseases, and it eventually succumbs to a causal agent or the pressures of competition from other more vigorously growing plants adjacent to the tree. The end result is no surprise. ::stage Snag:: The life span of a tree is as wide-ranging as the number of tree varieties, yet death is inevitable. Usually it is a combination of factors that finally overcome a tree and cause it to die. Injury, drought stress, followed by disease, rot, root dieback, coupled with a lightning strike and insect infestation is just one of many scenarios. However, sometimes it can be just one factor serious enough to cause mortality. Yet, the cycle does not end here. A standing dead tree, also called a snag, still plays a vital role in the life cycle. Decomposition takes time. A snag slowly breaks down and returns nutrients to the soil as small limbs, bark, and branches fall to the ground. The snag also provides habitat, cover, and food for wildlife and insects. In turn, animals, insects, and fungi help break down the tree. Eventually, the snag will fall to the ground and gradually return nutrients to the soil where they are taken up again by other trees by providing for their growth. And, the cycle begins anew. | mature survival is determined by external stresses | not_entailment | difference |

The optimum time to harvest trees for forest products beneficial to people is during this stage in the lifecycle. In Texas, the majority of products are made from southern yellow pine (loblolly, longleaf, shortleaf, and slash). Hardwoods such as ash, hickory, mesquite, pecan, and oak are also used but southern yellow pine is the main commercially grown species to meet public demand for wood products such as those listed below. A few of the products made from Texas trees include: paper, dimensional lumber, cabinets, molding, doors, pallets, boxes, crates, trusses, fireplace mantels, furniture, oriented strand board (OSB), flooring, crossties, joists, decking, log homes, posts, poles, cooking wood, fencing, fuel, interior finishing, pilings, bridges, animal bedding, mulch, heavy construction timbers, charcoal, shingles, and many more. If a tree is never harvested, over the course of time it continues to provide many other benefits, but eventually will begin to decline. ::stage Decline:: At this point, the tree's survival is determined more by external stresses rather than the tree's vigor. These stresses take a toll on the tree making it more susceptible to insects and diseases, and it eventually succumbs to a causal agent or the pressures of competition from other more vigorously growing plants adjacent to the tree. The end result is no surprise. ::stage Snag:: The life span of a tree is as wide-ranging as the number of tree varieties, yet death is inevitable. Usually it is a combination of factors that finally overcome a tree and cause it to die. Injury, drought stress, followed by disease, rot, root dieback, coupled with a lightning strike and insect infestation is just one of many scenarios. However, sometimes it can be just one factor serious enough to cause mortality. Yet, the cycle does not end here. A standing dead tree, also called a snag, still plays a vital role in the life cycle. Decomposition takes time. A snag slowly breaks down and returns nutrients to the soil as small limbs, bark, and branches fall to the ground. The snag also provides habitat, cover, and food for wildlife and insects. In turn, animals, insects, and fungi help break down the tree. Eventually, the snag will fall to the ground and gradually return nutrients to the soil where they are taken up again by other trees by providing for their growth. And, the cycle begins anew. | it can in the mature stage reproduce | entailment | difference |

::stage Seedling Stage:: After falling from the tree in October to late November, winged seeds whirl to the forest floor and await adequate moisture before germination. In heavy mast years, a rain shortly after seed fall will yield a green blanket of germinants on the forest floor. Seeds either germinate within a few weeks after falling or they die. Although seeds will germinate almost anywhere (on rocks, logs, forest mulch), they generally need to land on mineral soil to survive subsequent droughty periods. During this first stage, the seedlings are very susceptible to fire, drought and predation and will take upwards to a year to reach the next life stage. ::stage Grass Stage:: The grass stage is an inconspicuous yet unique stage of a longleaf pine's life history where the seedling resembles a clump of grass more than a tree, hence the name. During the grass stage, the growing tip (bud) of the tree is protected under a thick arrangement of needles at ground level. When fires sweep through, the needles may burn but the tip of the bud remains protected. New needles quickly replace those that were burned off. During the grass stage, longleaf pine seedlings are virtually immune to fire. At the grass stage, although the tree will not be growing upwards, the seedling will be putting down an impressive root system underground. Also during the grass stage, longleaf may become infected with a fungus called brown spot needle blight. Brown spot causes the needles to brown, fall off, and hamper growth. Repeated defoliation will cause the seedling to die. The grass stage may last anywhere from one to seven years depending on the degree of competition with other plants for resources. Rare instances of 20 years have been documented. ::stage Bottle Brush Stage:: When the diameter of the root collar (that area right at ground level) reaches 1-inch, the longleaf grass stage will begin to initiate height growth. Beginning in about late February to mid-March, a single, white growing tip will emerge upwards from the protective sheath of needles. This white tip, called a candle, may grow a few feet in just a few months. By about late May, green needles begin to emerge from the candle and the candle begins to turn scaly and brown as bark begins to form. At this point, the longleaf is growing proportionally more in height then it is in diameter. There are no branches spreading out horizontally during this time causing the tree to look like a three to four-foot bottlebrush. By growing rapidly in a short period of time, the seedling is able to secure an advantageous position to gather sunlight and to get its growing tip above the frequent fires. However, during this stage of growth, longleaf pine trees are slightly more vulnerable to fire. It may take a year or so before the bark thickens enough to withstand most fires. The longleaf may remain in this stage for a couple of years. ::stage Sapling Stage:: When the longleaf reaches about 6 to 10 feet in height, lateral branches begin to emerge and signal the beginning of the sapling stage. Diameter increases and bark thickens modestly, but the tree continues to grow in height at upwards of 3 feet per year. Around late February to mid-March white growing tips can be seen extending upwards from the tufted needles at the end of the branches. As the tree grows taller and the bark becomes thicker, the longleaf becomes less susceptible to fire. After the tree reaches 8 feet in height and about 2 inches in diameter at ground level, it becomes very robust and is rarely killed by fire. The tree will remain in this stage for several years. ::stage Mature Stage:: Somewhere around 30 years after height growth initiation, trees begin to produce cones with fertile seeds. As the forest begins to mature, lower limbs may be shed or pruned off by fire. The trunk of the tree begins to fill out into a straight, relatively branch free tree that resembles a living telephone pole (in fact, many longleaf pines are sold for telephone poles). On more fertile soils, the tree may continue to grow in height up to 110 feet. On poorer soils, the tree may only grow to 60 feet. After about 70 -100 years longleaf essentially ceases height growth. During the later stages of this period, trees may begin to show signs of decay and rot. In particular, longleaf pine reaching 80 years in age may become infected with a fungus called red heart that causes the otherwise dense heart of the tree to become punky, soft, sappy and full of small channels | Brown spot needle blight fungus is more likely to infect a mature tree than a tree at the grass stage. | not_entailment | difference |

Around late February to mid-March white growing tips can be seen extending upwards from the tufted needles at the end of the branches. As the tree grows taller and the bark becomes thicker, the longleaf becomes less susceptible to fire. After the tree reaches 8 feet in height and about 2 inches in diameter at ground level, it becomes very robust and is rarely killed by fire. The tree will remain in this stage for several years. ::stage Mature Stage:: Somewhere around 30 years after height growth initiation, trees begin to produce cones with fertile seeds. As the forest begins to mature, lower limbs may be shed or pruned off by fire. The trunk of the tree begins to fill out into a straight, relatively branch free tree that resembles a living telephone pole (in fact, many longleaf pines are sold for telephone poles). On more fertile soils, the tree may continue to grow in height up to 110 feet. On poorer soils, the tree may only grow to 60 feet. After about 70 -100 years longleaf essentially ceases height growth. During the later stages of this period, trees may begin to show signs of decay and rot. In particular, longleaf pine reaching 80 years in age may become infected with a fungus called red heart that causes the otherwise dense heart of the tree to become punky, soft, sappy and full of small channels | a seedling tree lacks can cones | not_entailment | difference |
::stage Seedling Stage:: After falling from the tree in October to late November, winged seeds whirl to the forest floor and await adequate moisture before germination. In heavy mast years, a rain shortly after seed fall will yield a green blanket of germinants on the forest floor. Seeds either germinate within a few weeks after falling or they die. Although seeds will germinate almost anywhere (on rocks, logs, forest mulch), they generally need to land on mineral soil to survive subsequent droughty periods. During this first stage, the seedlings are very susceptible to fire, drought and predation and will take upwards to a year to reach the next life stage. ::stage Grass Stage:: The grass stage is an inconspicuous yet unique stage of a longleaf pine's life history where the seedling resembles a clump of grass more than a tree, hence the name. During the grass stage, the growing tip (bud) of the tree is protected under a thick arrangement of needles at ground level. When fires sweep through, the needles may burn but the tip of the bud remains protected. New needles quickly replace those that were burned off. During the grass stage, longleaf pine seedlings are virtually immune to fire. At the grass stage, although the tree will not be growing upwards, the seedling will be putting down an impressive root system underground. Also during the grass stage, longleaf may become infected with a fungus called brown spot needle blight. Brown spot causes the needles to brown, fall off, and hamper growth. Repeated defoliation will cause the seedling to die. The grass stage may last anywhere from one to seven years depending on the degree of competition with other plants for resources. Rare instances of 20 years have been documented. ::stage Bottle Brush Stage:: When the diameter of the root collar (that area right at ground level) reaches 1-inch, the longleaf grass stage will begin to initiate height growth. Beginning in about late February to mid-March, a single, white growing tip will emerge upwards from the protective sheath of needles. This white tip, called a candle, may grow a few feet in just a few months. By about late May, green needles begin to emerge from the candle and the candle begins to turn scaly and brown as bark begins to form. At this point, the longleaf is growing proportionally more in height then it is in diameter. There are no branches spreading out horizontally during this time causing the tree to look like a three to four-foot bottlebrush. By growing rapidly in a short period of time, the seedling is able to secure an advantageous position to gather sunlight and to get its growing tip above the frequent fires. However, during this stage of growth, longleaf pine trees are slightly more vulnerable to fire. It may take a year or so before the bark thickens enough to withstand most fires. The longleaf may remain in this stage for a couple of years. ::stage Sapling Stage:: When the longleaf reaches about 6 to 10 feet in height, lateral branches begin to emerge and signal the beginning of the sapling stage.

::stage egg:: eggs are laid by female birds in clutches ranging in number from just 1 for condors to as many as 17 for the grey partridge. Eggs are incubated by one or both parents for a period of time until the embryo inside has developed into a chick which is ready to hatch. A chick may have to work for hours or even days to break through the shell of its egg. Most birds have a small bump near the tip of their beak called an egg tooth to help them hatch. ::stage hatchling:: a hatchling is a bird that has just hatched and may be almost completely naked apart from some fine down. Hatchlings eyes may not open and it is unlikely to be able to care for itself. The term hatchling is usually used to refer to altricial chicks which are undeveloped and unable to move around. Hatchlings will stay in the nest for some time and will rely on their parents for feeding and to keep them warm. Precocial birds such as ducks and owls are relatively mature when they are born and are sometimes able to feed themselves and leave the nest soon after. ::stage nestling:: nestlings are chicks that are a few days old and are covered in soft down. There may be signs of flight feathers and nestlings eyes may have opened but they will be unable to leave the nest and will still rely on their parents for food and warmth. ::stage fledgling:: chicks that have developed flight feathers and wing muscles are known as fledglings. fledglings will have started to explore outside the nest but will still be under the care of their parents. Fledglings are fairly awkward and only able to fly for short distances but will be active and able to hop about. The length of time it takes for a chick to fledge varies between species. For example it takes 6 months before the chicks of the great frigatebird fledge and their parents feed them for a further 14 months. ::stage juvenile:: a juvenile bird is at the awkward teenage stage of being a bird. Juvenile birds will have left the nest and will be fully independent. juvenile bird will be in their first plumage and can look similar to adult birds although they may be duller with less defined markings. Out in the field it can be difficult to identify a juvenile bird and for most species of birds the length of time they are a juvenile is very short. ::stage subadult:: subadult birds are young birds that are older than juveniles but have still not developed adult plumage and are not sexually mature. Some birds such as house sparrows will become sexually mature at just a few months whereas larger birds such as golden eagles won't become sexually mature until they are 4 or 5 years old. The terms immature and subadult are interchangeable by many ornithologists although immature can be used to refer to any bird that isn't an adult. ::stage adult:: adult birds are sexually mature and are able to reproduce. adult birds will be in full adult plumage which may change depending on the season. Some birds have brighter plumage with clearer markings when in breeding season while in other birds, such as puffins, the shape and colour of their bills may change. | fledgling have the ability to Fly | entailment | difference |

A chick may have to work for hours or even days to break through the shell of its egg. Most birds have a small bump near the tip of their beak called an egg tooth to help them hatch. ::stage hatchling:: a hatchling is a bird that has just hatched and may be almost completely naked apart from some fine down. Hatchlings eyes may not open and it is unlikely to be able to care for itself. The term hatchling is usually used to refer to altricial chicks which are undeveloped and unable to move around. Hatchlings will stay in the nest for some time and will rely on their parents for feeding and to keep them warm. Precocial birds such as ducks and owls are relatively mature when they are born and are sometimes able to feed themselves and leave the nest soon after. ::stage nestling:: nestlings are chicks that are a few days old and are covered in soft down. There may be signs of flight feathers and nestlings eyes may have opened but they will be unable to leave the nest and will still rely on their parents for food and warmth. ::stage fledgling:: chicks that have developed flight feathers and wing muscles are known as fledglings. fledglings will have started to explore outside the nest but will still be under the care of their parents. Fledglings are fairly awkward and only able to fly for short distances but will be active and able to hop about. The length of time it takes for a chick to fledge varies between species. For example it takes 6 months before the chicks of the great frigatebird fledge and their parents feed them for a further 14 months. ::stage juvenile:: a juvenile bird is at the awkward teenage stage of being a bird. Juvenile birds will have left the nest and will be fully independent. juvenile bird will be in their first plumage and can look similar to adult birds although they may be duller with less defined markings. Out in the field it can be difficult to identify a juvenile bird and for most species of birds the length of time they are a juvenile is very short. ::stage subadult:: subadult birds are young birds that are older than juveniles but have still not developed adult plumage and are not sexually mature. Some birds such as house sparrows will become sexually mature at just a few months whereas larger birds such as golden eagles won't become sexually mature until they are 4 or 5 years old. The terms immature and subadult are interchangeable by many ornithologists although immature can be used to refer to any bird that isn't an adult. ::stage adult:: adult birds are sexually mature and are able to reproduce. adult birds will be in full adult plumage which may change depending on the season. Some birds have brighter plumage with clearer markings when in breeding season while in other birds, such as puffins, the shape and colour of their bills may change. | hatchling do not have the ability to Fly | entailment | difference |
