The Basin contains nationally significant expanses of bottomland hardwoods, swamplands, bayous, and back-water lakes. The bohor reedbuck inhabits moist grasslands and swamplands as well as woodlands. The swamplands, which used to be marshy, now produce vegetables, rice, tobacco, beets and sunflowers. In contrast, the northeastern portion of the peninsula is characterised by forested swamplands. Most of the swamplands are actually mangroves that served as habitat to different marine species. The Black Swamp Conservancy, founded in 1993, has also been involved in preserving former swamplands. The swamplands of the Great Morass and the Upper Morass fill much of the plains. In the 1870s, former delta swamplands were being transformed, via levee construction, into fertile farmland. These areas were all very sparsely populated and consisted of farm fields, woods and swamplands. The town is almost canalized but houses are within the gulf and the swamplands. In 1909, R.P. Davie assisted then Florida Governor Napoleon Bonaparte Broward by draining swamplands. The remaining few hundred Seminoles survived in the Florida swamplands, avoiding removal. It is generally flat with rolling hills and swamplands in its western part. Together, they deduce "SWAMPLANDS", meaning "bog". Attempts to reclaim the lower swamplands were ineffective.
