reach an agreement with fire crews at ENP to allow them to burn county properties have stalled.
|
The EEL program should investigate the use of private contractors to implement an effective fire
|
management program (see also Part I, Section 5.2.1). Several companies in Florida provide this
|
service and their use in Miami-Dade County should be encouraged. Costs of using private
|
contractors may be much higher than using FDOF, but the absence of fires will result in
|
increasing hardwood removal costs, decreasing habitat quality, and increasing threat of
|
damaging wildfires.
|
4.6.4 Alternatives to Prescribed Burning
|
If the application of prescribed fire is absolutely impossible, there are several alternatives that are
|
available, although less desirable. These options include grazing, herbicide application, and
|
mechanical treatment. Grazing, such as by goats, has the disadvantage of introducing trampling
|
effects, nutrients from feces, and possible spread of exotic pest plant seeds. Both herbicide
|
application and mechanical treatments have the disadvantage of requiring that dead woody
|
material be removed from the site following treatment to limit the amount of decomposing
|
vegetation that would create organic soils. Even with physical removal after treatment, organic
|
matter from all plants on the site will eventually accumulate, leaving an organic soil, and thereby
|
reducing diversity of native herbs and potentially introducing invasive species. Physical removal
|
after treatment can also cause disturbances. In addition, none of these techniques replicate a
|
fire’s ability to return nutrients to the soil for short periods of time, a process that is critical to
|
many pine rockland plant species. These alternative techniques, as opposed to prescribed
|
burning, require a significantly greater labor commitment from personnel and come at a
|
significant ecological cost.
|
4.7 Management after Tropical Cyclones
|
As discussed in 2.6.2 and 3.6.2, tropical cyclones, including tropical storms and hurricanes, can
|
break or topple pine trees, make pine trees susceptible to pest insect outbreaks, and defoliate or
|
damage understory hardwoods. Storms can also blow manmade debris into pine rocklands,
|
including large items such as shipping containers and boats, which can damage vegetation and
|
soils. In addition to these direct effects, post-storm impacts from people can also be considerable,
|
including dumping, habitat clearing, and establishment of campgrounds or temporary homes.
|
Management Policy
|
Post-storm evaluations shall be conducted at all pine rockland EEL sites to determine the
|
extent and severity of damage to vegetation, wildlife, and structures. After inspection, an
|
action plan shall be developed to mitigate any impacts caused by the event.
|

|
Establishment of post storm security should be a top priority, including temporary erection of
|
fences, gates, and signs. If existing signs are destroyed, inexpensive, temporary “no dumping”
|
signs should be installed liberally around property perimeters. Sites should be inspected regularly
|
for dumping and trespassing.
|
Maintenance of a sparse pine canopy, as discussed in Section 4.3.1, will limit outbreaks of pest
|
insects, including Ips beetles, following storms. If infestations do begin, trees can be protected by
|
the application of Onyx, a bark-adhering formulation of bifenthrin that is applied to bark.
|
Infested trees should be cut down and sprayed with Onyx. If other chemicals are available for
|
this use, they can be tried as well.
|
4.8 Hydrological Restoration
|
Pine rocklands are upland communities but have been stressed by a lowered water table, for
|
example, in recovery from wind damage or fires. Though it is unlikely that any small scale, site
|
specific project, could occur to remedy this problem, large scale restoration would be very
|
beneficial to stressed pine rocklands. While such large scale restoration projects are not feasible
|
for the EEL program to accomplish alone, EEL would support and partner with any existing or
|
proposed restoration plans that would attempt to elevate water tables closer to historic levels.
|
Water levels that re-hydrate adjacent wetlands would be very advantageous for the adjacent pine
|
rocklands.
|
4.9 Soil Management
|
Pine rockland soils are naturally nutrient poor. However, successional changes lead to changes in
|
the soil. In the absence of fire, hardwoods invade pine rockland habitat, resulting in inhibition of
|
pine regeneration. As hardwoods invade, accumulation of organic matter in the soils and
|
increased shading results in an increase in soil moisture, which inhibits fires that maintain the
|
pine rockland community.
|
Because pine rockland soils are naturally nutrient poor, proper ecosystem management
|
(particularly burning) will maintain the low fertility of pine rockland soils. Accumulation of
|
organic matter increase the nutrient levels and favor the invasion of pine rockland habitat by
|
hardwoods. Winter backing burns can be used to reduce the levels of organic matter in the soil of
|
those sites where the accumulation is already higher than desirable.
|
Direct use of fertilizers and other nutrient applications are forbidden. Inputs from off-site nutrient
|
sources that migrate into pine rocklands should be prevented and controlled in case they are
|
Management Policy
|
Soil on pine rockland EEL sites shall be managed by prescribed burning. Direct use of
|
fertilizers and other nutrient applications are forbidden on any pine rockland EEL site.
|
Management Policy
|
The EEL program will support any large scale restoration project which would be
|
beneficial to the hydrological restoration of pine rockland EEL sites.

occurring. Source reduction of nutrients might be needed to reduce edge-of-field and leaching
|
from neighboring agricultural areas (see Part I, Section 5.2.5).
|
4.10 Cultural Resources
|
Cultural resources on pine rockland EEL sites should be managed in accordance with the
|
management policy for all Miami-Dade County EEL preserves. Please refer to Part I, Section 3.3
|
of this management plan for details about management of cultural resources on EEL sites.
|
4.11 Pollution Control
|
Generally, the goal of source reduction to control pollutants applies to all pine rockland EEL
|
sites in the same manner as it does for all other EEL sites. Please refer to Sections 5.2.5 and 5.4.3
|
in Part I of this management plan for management and contingency management of pollutants in
|
and around EEL preserves.
|
4.12 Landscaping Considerations
|
Landscaping adjacent to pine rocklands should be done to minimize the threat of invasive exotic
|
plants and also native plant species that could become maintenance problems in the ecosystem.
|
No plant species listed by the FLEPPC as Category I or II (Appendix C) should be planted on
|
EEL sites. Exotic plant species that can naturalize, even those not listed by FLEPPC, should not
|
be planted on EEL sites. Lists of exotic species that naturalize in South Florida can be found
|
online at www.regionalconservation.org in the Floristic Inventory of South Florida database, or
|
at www.plantatlas.usf.edu/, the Atlas of Florida Vascular Plants. Cultivated trees that are
|
FLEPPC listed or that naturalize should be removed from EEL sites where they are already
|
present.
|
Native hardwood species that may invade pine rocklands should not be used, including live oak,
|
wild tamarind, gumbo limbo, and others. Where already cultivated on EEL sites, their removal
|
should be considered.
|
Management Policy
|
All landscaping that occurs adjacent to pine rockland EEL sites should avoid exotic
