The importance of playa wetlands to biodiversity of the Southern High Plains
Abstract We describe the landscape of the Southern High Plains, including the important remaining native feature of the area; playa wetlands. Playas are ephemeral wetlands on the prairie occupyingExpand

Assessment of the effects of farming and conservation programs on pesticide deposition in high plains wetlands.
We examined pesticide contamination in sediments from depressional playa wetlands embedded in the three dominant land-use types in the western High Plains and Rainwater Basin of the United StatesExpand

Floral Diversity in Relation to Playa Wetland Area and Watershed Disturbance
There are 25,000-30,000 playa wetlands in the intensively cultivated Southern Great Plains of the United States. Knowledge of area and watershed influences on wetland flora are needed to guide theirExpand
