Info

Proximity to primary and secondary roads – Within a quarter mile of a major roadway. Hydrology – The hydrology has been altered to some extent by a series of small drainage ditches (very shallow and narrow), but water flow still seemed to be pretty good within the site. There are large canals associated with a developed road at least along the southern edge, so this site is hydrologically isolated from most if not all of the surrounding area (which is largely already converted to citrus groves and farmland).

The site is still very, very, nice though, with only a few scattered exotics. There are a few undeveloped access roads, and a large powerline bisects the site. The eastern end (and some patches near the central portion of the western end) looked to largely be heavily grazed pasture, but the areas are still dominated by native species. Table 3.

Ownership/Notes – This site is nice, especially the large extensive Wet Prairies and Depression Marshes. There are four landowners. Recommendation/Management Requirements – The ditches should be filled in. Exotics should be removed. In the long term the cattle should be removed but, in the absence of fire, the grazing is likely helping to maintain the site integrity by keeping the prairies and marshes free of woody vegetation. 140
