vegetation observed. There are some small ditches in the northern sections that will need to be filled to restore natural sheet flow. Table 2. Community Types present on site and their rankings.

There is evidence that portions of the site have been burned recently. Brazilian pepper is scattered throughout the site especially on the edges of the wet prairies and depression marshes. There are no significant dense stands of Brazilian pepper except along the canals. There are some native grasses in the dry prairie but much of it is dominated by bahiagrass and cogongrass with caesarweed in isolated areas. Some of the flatwoods also have bahiagrass and caesarweed. In the southern section of the site there appears to be less evidence of exotics, but site inspection was only done from the road. Table 3.

Invasive Exotic Species observed Common Name Scientific Name FLEPPC Status State Status Brazilian Pepper Schinus terebinthifolius Cat I prohibited none Caesaerweed Urena lobata Cat II none none Federal Status Ownership/Notes – Permission for ground access was not available for the southern section of the site however, the portion was viewed from the edge and appeared to be similar to the rest of the site that was ground surveyed. The owner of this southern portion indicated that he did not want to have his land considered for natural land acquisition purposes. There are 5 landowners. The largest land owners are Southern Fruit Groves (1097 acres) and Monahan (1022 acres). Recommendation/Management Requirements – The exotics need treatment so that they do not to further encroach on the native systems. Brazilian pepper is scattered 133
throughout the site as is caesarweed. Most of the Dry Prairies need to be treated for cogon and bahia grass. In addition, implement a prescribed fire rotation of 3-7 years to maintain a flatwoods-prairie ecosystem. 134
