Land stewardship is about taking care of the soil, of native grasses, trees and shrubs, and of sources of water, such as rivers, lakes, creeks and streams. The aim is to preserve and maintain the biodiversity and health of natural ecosystems, which benefits humans, soil creatures, birds and other wildlife. The HELM program in central Texas works with landowners to educate and encourage them to become good stewards of their land. HELM stands for Habitat Enhancing Land Management.
