Activity 1
Total number of species present: 9
Number of endangered species present: 0
Hypothesis:
Replant longleaf pines, restore wire grass start prescribed burns
Total number of species present after strategy applied: 15
Number of endangered species present after strategy applied: 1
1) After reviewing all the management strategies, which allows for the greatest species
biodiversity? Describe this biodiversity. Why do you think this strategy is so restorative?
The management strategy that allows the gressest species biodiversity is replanting longleaf pines,
restoration of wire grass, and prescribed bores. There is a presence of IS different species and I
endangered species. Longleaf pine ecosystems in the soutbeastern United States are managed to
promose long-term resilience and sastainability. Wiregrass restoration and prescribed burns are
crucial components, allowing for the growth of understory plats and reducing fuel loads. Prescribed
burning also increases biodiversity by creating a mosaic of different habitats within the forest.
Replanting longleaf pines is essential, as they provide babitat for otber species and are a keystone
species in the ecosystem.

The strategies in Trial I are some of the most effective ways to restore ecosystems in the Southen
eastern United States. The restoration of longleaf pine forests is one of the most successful
conservation efforts in the region. The restoration of longleaf pine forests involves replanting
longleaf pises, restoring wire grass, and prescribed burns. These management strategies have allowed
19 different species to thrive. S of which are endangered species. Gopher tortoises are one of the
keystone species that benefit from longleaf pine restoration. Restoring wetlands is also an important
part of ecosystem restoration.
Activity 3
Hypothesis:
Initiate longleaf pine agroforestry
Total number of species present after strategy applied: 11
Number of endangered species present after strategy applied: 1
3) After reviewing the lucrative management strategies, which is least damaging to the
ecosystem (allows for the greatest biodiversity)? How does this strategy differ from the others
in this Activity?
The best management strategy is to initiate a longleaf pine agroforestry as it is the least damaging to
the ecosystem. This strategy stil/allows the presence of I1 species, one of which is endangered to
thrive. This strategy differs from the other strategies because it has double the number of present
species than any other strategy

A scientific model is only as reliable as the data used to construct it. In this case, the simulations
carried out here are based upon a basic ecological understanding of the longleaf pine ecosystem,
include a review of basic books on the topic supplemented by a few past field visits. None of the
results in this lab has been reproduced in the field. All outcomes from these scenarios are therefore
highly speculative. Further, for each particular case, there are intervening variables, such as local
hydrology, bedrock geology, and local soils, as well as ecological health of surrounding areas that
could affect the results obtained. Consider this lab only a very rough approximation of how the
longleaf ecosystem might be affected by various human impacts, including restoration work.
