Effects of climate and land management on the type and location of vegetation in wetlands (PNAS)

Periodic floods are a normal occurrence in wetlands. To find out how these floods impact niches of different plant species in wetlands, Princeton researchers studied plant species in Everglades National Park (ENP) in Florida. They found that the sizes of the clusters of each species follow a power law probability distribution and that such clusters have well-defined fractal characteristics. They modeled the effect that periodic flooding and neighboring vegetation have on plant clusters. They found that climate and land management have a predictable impact on the type of vegetation and its spatial organization in wetlands. The findings are highly relevant for the management of wetland ecosystems.
