More Text AnoVU combined with rising sea levels increased the presence of salt water in freshwater areas. Most bald cypress seedlings cannot survive in water with high concentrations of salt. Bald cypress trees depend on occasional forest fires to prevent other types of trees and shrubs from invading their habitat. Without these fires, other tree species would eventually take over a stand of bald cypress trees and change the ecosystem. Cypress swamps benefit people and animals; they absorb water during floods, filter waste from runoff by trapping it in plants and sediments, and provide habitats and food for many species. The diagram shows food web relationships between some of the organisms in a cypress swamp.
