All exotic plant control methods in pine rocklands should limit soil disturbance. Soil
|
disturbances can create opportunities for invasion of the same exotic plant being removed or for
|
new exotic or ruderal species. While utilizing techniques such as hand pulling or digging, soil
|
disturbance should be reduced as much as possible. Chemical control or cutting of exotic plants
|
can also be employed as alternatives to soil disturbing activities.
|
Management Policy
|
Exotic plants must be eliminated from pine rockland EEL sites or maintained at very
|
low densities. Planting of these species on pine rockland EEL sites is forbidden.

4.5.2 Animals
|
Populations of exotic animals in the pine rockland community should be evaluated for their
|
impact to these habitat. In addition to feral domestic cats, already discussed Part I of this
|
management plan (see Section 5.2.2.2), the following non-indigenous animals have the potential
|
to impact pine rockland communities to varying degrees. Non-indigenous animals should be
|
targeted for removal from pine rockland fragments, especially when they alter ecosystem
|
processes, compete with native wildlife, or damage native plant species. Control of some species
|
may be impractical or even impossible.
|
Red imported fire ant β Fire ants may be controlled by treating individual mounds or through
|
broadcast treatments. While broadcast treatments are more effective at eliminating entire
|
colonies, this technique should generally be avoided in EEL pine rocklands so as not to impact
|
populations of native ant species. There are many options for mound treatment, but the most
|
appropriate and effective in natural areas is probably placing toxic bait directly on individual
|
mounds. Biological controls are also being tested in Florida and may prove to be appropriate for
|
EEL sites. These include a decapitating fly of the genus Pseudacteon which attacks fire ant
|
workers and a fire ant disease, Thelohania solenopsae (Willcox and Giuliano 2006).
|
European starling β Numerous products exist for controlling starlings, but many of these would
|
likely disturb native birds as well. There are auditory repelling devices designed to target this
|
species by emitting their distress calls, but experimentation should be done prior to installation to
|
ensure that they only impact starlings. Even if effective, this method may only work in smaller
|
pineland fragments where enough devices could be set up to cover the entire area.
|
Parrots and parakeets β Managing for members of the Psittacidae family may not be possible.
|
These birds are highly charismatic and are adored by the public. Any large-scale effort to control
|
their populations will likely be met with outrage. The only option may be monitoring of nest
|
cavities and manual removal of non-native birds.
|
Lobate lac scale β Protected pine rockland areas should be monitored for the presence of this
|
species and control measures implemented in the area if detected. Some woody plant species
|
appear to be highly susceptible, including certain natives, e.g., wax-myrtle, strangler-fig,
|
myrsine, swamp bay, and wild-coffee. Control can be accomplished in part by following regular
|
subcanopy management recommendations β cutting and burning. In some cases, especially for
|
rare plants, an insecticidal solution may be applied for several weeks to kill the scales. Treatment
|
of lobate lac scale is particularly important in areas with rare bushes, especially Florida
|
prairieclover and crenulate leadplant, which have been observed with infestations.
|
Management Policy
|
Control measures must be developed and implemented at pine rockland EEL
|
preserves to halt and reverse the spread of invasive naturalized exotic animal species
|
and to prevent the establishment of new exotic animal species populations

4.6 Fire Management
|
Since pine rocklands are fire climax communities, fire management, along with exotic plant
|
control, is one of the most critical techniques required to restore and manage pine rocklands.
|
Site-specific recommendations and objectives for prescribed fires will be presented in Part III of
|
this management plan. General recommendations for fire management are discussed here,
|
including hardwood control, fire breaks, prescribed burning, and alternatives to prescribed
|
burning.
|
4.6.1 Hardwood Control
|
Manual, mechanical, or chemical hardwood
|
control will be required at many pine
|
rockland sites to prepare for prescribed
|
fires. The amount of woody material to be
|
removed should be coordinated with the
|
burn team. Hardwood and palm densities
|
should be reduced prior to burning to
|
reduce burn temperatures. An added benefit
|
is the reduction of smoke levels during and
|
post-fire, and less need for mop up.
|
4.6.2 Fire Breaks
|
Fire breaks should be maintained or installed around all pine rocklands. Construction of these
|
fire breaks is necessary to permit access for fire fighting equipment and staff. Fire breaks are also
|
essential to protection of structures and surrounding properties if and when wildfires occur.
|
Only general considerations about fire breaks are made here in Part II. Their specific location on
|
each site is discussed in Part III of this management plan.
|
Though utilizing existing rights-of-way as fire breaks is preferred, fire break construction may
|
require destruction of some pine rockland habitat. Nevertheless, fire breaks, and the consequent
|
habitat destruction, are necessary to properly control a burn, and if fires cannot be set then the
|
entire site will degrade, making the cost of limited habitat destruction worthwhile. Fire breaks
|
should be cleared to bare rock or soil, which will not only prevent ground fires from crossing
|
them, but will create habitat for pine rockland plant species and limit invasion of exotic and
|
ruderal plant species (see Section 4.5.1 above).
|
Management Policy
|
Fire management on all pine rockland EEL sites shall concentrate on a prescribed
|
burning program, along with hardwood control and installation and maintenance of
|
fire breaks. The prescribed burning program must account for seasonality of burns,
|
personnel necessary, the risk of wildfires, and actual application, including safety
|
measures and effectiveness. Alternatives to prescribed burning will only be utilized as
|
a last resort.

4.6.3 Prescribed Burning
|
As discussed in Section 2.6.1 above, large wind-driven fires historically swept across the South
|
Florida landscape every three (3) to seven (7) years, especially in the spring and summer. More
|
recently, as discussed in Section 3.6.1, fire frequency has been drastically reduced or eliminated
|
on most sites, resulting in changed vegetation structure, decreased plant diversity, and increased
|
fuel loads. To compensate for the lack of natural fires, prescribed burns should be applied to pine
|
rocklands every three (3) to seven (7) years.
