Designing A Route Open Spaces- Constant Change of the Grassland of the United States By Lori Anne Gross and Brook Mulford Concept Summary Grasslands of the United States are in constant change. Many factors are taking land out of production each day. Every minute, rural America loses two acres of land to development.
Grasslands are important to our food and fiber supply.
They are renewable resources that could not be utilized without grazing animals. The number of organisms an ecosystem can support depends on the resources available and abiotic factors, such as quantity of light and water, range of temperatures, and soil composition. This lesson contains two 45-minute class sessions. The Background Information handout is important for students to learn vocabulary associated with grazing and grasslands. The handouts will help them understand the role of grasslands in our food and fiber system.
