Celebrating Trees in Grasslands

Did you know that trees can play a vital role in some types of grassland communities? Approximately 200 different types of grasslands have been identified in the Southeast and several of those grassland communities include trees. This fact often surprises people because of our common view that grasslands are completely devoid of trees. In this photo essay we are celebrating some of the grassland communities that include trees, as well as some of the plants and animals that make up those communities.

Small and stunted post oaks in this rare Ozark Shale Barrens have been cored and dated at more than 250 years old. While post oaks can survive in closed canopy forests, they require open areas with lots of sunlight in order for the seedlings to become established. Kessler Mountain. Washington County, Arkansas.

The USFWS considers the federally threatened Louisiana pine snake one of the rarest snakes in North America. One of the reasons for its decline is a loss of habitat, especially longleaf and shortleaf pine savannas. Photo credit: USFWS

Eastern bluebirds, a favorite visitor to many people’s yards, are cavity nesters that require open areas. Today, bluebirds commonly nest in bluebird houses, but their natural nest sites would have been in hollow trees found in savannas and open woodlands. Photo credit: Shenandoah National Park
