Rangelands and Grazing

What is a Rangeland? Rangeland – an area with NATIVE low-lying plants (grasslands, prairies, savanas, etc) Not farmland FERTILE SOIL Involves clearing trees (deforestation) Grazing – animals eating plants (grass) in one place

Grazing…the good and the bad Grazing – a necessary evil Pros: increases soil fertility (if done sustainably) Manure = nutrients for soil Cons: Overgrazing = soil erosion, less soil fertility, water quality (from manure)

Grazing gone wrong… Desertification – conversion of rangeland to desert via overgrazing Other causes: drought, soil erosion from too much rain, wind blowing away soil, etc. Law: Public Rangelands Improvement Act – grazing permits required (sustainability), more productivity

Solutions to Desertification? TED Talk http://www.ted.com/talks/allan_savory_how_to_green_the_world_s_deserts_and_reverse_climate_change.html

Rangeland Management Controlling # of livestock on land Damaged rangeland…restored Planting grass, sufficient water, etc. Fire-prone (lightening) Rotate grazing area (sustainable) Fencing off Riparian Zones – lush strip of vegetation near a stream Rich in biodiversity

Fire and Rangeland Management Fires = common (lightening, fire-prone plants) Grasslands Why it’s good: Eliminates invasive species Native grasses need fire to grow (like sequoias) Nutrients back in soil (fertile)

Quick Quiz #3 Identify a specific type of plant community or biome (other than a forest) that is naturally maintained by fire. Explain how the fire maintains the community or biome. (AP TEST QUESTION) Why are rangelands in danger of desertification? Describe one technique of how this can be managed. What are riparian zones, and why do you think they would be zoned off from grazing?

Warm Up #7 Of the suggestions in the Rangelands Improvement Act, which do you think will be the most effective, and why? Identify TWO specific human activities that result in a loss of biodiversity and explain how each activity lowers biodiversity. For each of the two human activities listed, explain how you could solve these problems (other than simply stopping them altogether). What are some direct/indirect consequences of controlled fires in a grassland/rangeland ecosystem?
