1. Forestry and Rangelands Hunter Kilborn and Bhakta

2. Ecological Services Provide habitats Carbon Sinks Affect local climate Purify air and water Reduce soil erosion Provide energy and nutrient cycle

3. Old-Growth Forests Old to Middle-aged trees Minimal human activity Multi-layer canopy Fungal ecosystem Indicator species Healthy soil

4. Fires Help clean the forest of leaf litter Improve soil health Surface Fires clear leaf litter, kill seedlings, and undergrowth. Ground fires are hard to detect. Crown Fires happen when there hasn’t been fires in a long time. Super hot and destroy the forest.

5. Deforestation Selective-cutting- Cutting certain trees in an area. Strip-cutting- cutting a strip of trees out of a forest. Clear-cutting- Clearing the forest or a large area of the forest.

6. Rangelands Problems: Overgrazing, desertification. Overgrazing- the over use of rangelands as a source of food for steer and cattle. Desertification- result of abuse of the land from multiple causes. Results in increased soil erosion and decreased fertility.

7. Fun Facts Rangelands are 40% of the United States landmass. 80% of the western US are rangelands. Mostly arid to semi-arid climates. Only 7% of the east coast are rangelands. Regulated and controlled by the Bureau of Land Management (BLM), and the Forest Service.
