• Gopher tortoise – This state-listed Species of Special
Concern has been recorded in pine rocklands in MiamiDade County, including some EEL sites where it is
limited to the northern Biscayne pinelands which possess
the sandy soils required by this species. Gopher tortoise
burrows provide important habitat for numerous other
species so management for gopher tortoises benefits a
wide range of wildlife.
• Rimrock crowned snake – This small species of
fossorial snake is endemic to rockland habitats
extending along the Miami Rock Ridge in
Miami-Dade County down into the Middle
Florida Keys of Monroe County. Very little is
known about this elusive snake, but limited
findings and drastic reduction of its native
habitat have gained it a classification of
Threatened by the State of Florida.
• Florida leafwing butterfly – This subspecies is
endemic to South Florida and the Florida Keys,
occurring only in pine rocklands containing
pineland croton, its sole host plant. Once
widespread in Miami-Dade County, habitat
loss has depleted its numbers and restricted its
presence to Long Pine Key in ENP and Big
Pine Key in the lower Florida Keys. EEL
pinelands along the edge of ENP may be
crucial for this species’ recovery. This species
is a candidate for federal listing.
• Bartr
am’s hairstreak butterfly – This subspecies is
endemic to South Florida and the Florida Keys,
occurring only in pine rocklands containing
pineland croton, its sole host plant. Once
widespread in Miami-Dade County, habitat loss has
depleted its numbers and largely restricted its
presence to Long Pine Key in ENP and Big Pine
Key in the lower Florida Keys. There appear to be
some small, localized populations just outside of
ENP and sightings of this species have been
confirmed as far away as the Miami Metro Zoo.
This species is a candidate for federal listing.

3.8 Fragmentation, Ownership, and Preservation Status of Remaining Fragments
Pine rocklands in Miami-Dade County are owned by a variety of public agencies and private
individuals. Properties owned by public agencies are usually preserves, although there are some
major exceptions. Most privately-owned pine rockland fragments have the potential to be
developed, although a few sites are maintained as preserves by their owners. About 26% of the
remaining pine rockland acreage in Miami-Dade County is privately owned. Each ownership
category is discussed in more detail below.
3.8.1 Fragmentation
The pine rockland ecosystem has been extensively fragmented. Only 1.8% of the historical
extent of pine rocklands remain outside of ENP, with only 2,273 acres of historically estimated
127,000 acres left (Bradley, unpublished data). Fragments range from 0.25 acres to 800 acres,
with a mean size of 15.6 acres and a median size of 4.3 acres.
3.8.2 EEL Program
The EEL program owns approximately 474 acres of pine rockland on 24 sites. All of this acreage
will be protected and managed in perpetuity.
3.8.3 Parks & Recreation Department
The Miami-Dade County Parks and Recreation Department owns or leases about 817 acres of
pine rockland on 15 properties. On some of these sites, the pine rockland is not fully protected,
including 255 acres at Miami Metrozoo, which may be developed in part by the Parks and
Recreation Department for other purposes.
3.8.4 Other Public Lands
Several public agencies own pine rockland fragments, including the U.S. Government (mostly
the Department of Defense), and the School Board of Miami-Dade County.
The Miami-Dade County School Board owns seven pine rockland fragments totaling 49.3 acres.
These sites include the 6.4 acre Ron Ehman Park, the 10.4 acre Ned Glenn Nature Preserve, a
15.6 acre property at Moody Drive and the Florida Turnpike, 2.6 acres at Southwest 216th Street
and 129th Avenue, 10.8 acres at Southwest 199th Avenue and 324th Street, 4.8 acres at Robert
Morgan Education Center at Southwest 184th Street and 122nd Avenue, and 4.3 acres at
Southwest 224th Street and 115th Avenue. Ron Ehman Park and the Ned Glenn Nature Preserve
are somewhat secure from development via agreements with Miami-Dade County. The School
Board plans to develop schools on the other sites.
The U.S. Government owns a number of pine rockland fragments. The Department of Defense
owns 177 acres of pine rockland at the Richmond Pineland Complex surrounding MiamiMetrozoo. One 67-acre parcel that was formerly the U.S. Naval Observatory was recently deeded
to the University of Miami. Other federal land in the complex could be developed, or again
transferred to private ownership. The U.S. Board of Prisons also owns a 21.3 acre pine rockland
