Wetland, Savanna,
Forest and Prairie of Dallas County
Because Dallas County is the meeting place
of three, regionally defined, plant communities, it is an area potentially
rich in diversity. It is difficult to categorize specific plant
communities on a small scale, as representative of each regional
type. Alterations from intensive land use and natural distribution
patterns influence land cover throughout the County.
