Terrestrial Biodiversity (Chapter 10 APES)

Sustainable Terrestrial Biodiversity: The Ecosystem ApproachMaria Garcia & Shandrell Mosley

Forests

Grasslands

Threats to Forest Ecosystem:1) There is a high rate of tropical deforistation and it's growing because of global warming.2) Unsustaintable cutting down trees and burning of forests.3) Crop & timber, poverty, population grow, government policies.(Basic Causes)Sustaining the Forests:1) Protect areas with high biodiversity2) No logging of old growth forest3) No clear-cutting on steep slopes4) Certify timber grown by sustainable methodsSustaining Tropical Forests:1) Protect the most diverse & endangered areas2) Subsidize only sustainable forest use3) Rehabilitat degraded areas

What is the Ecosystem Approach to Sustaining Biodiversity

Grasslands provide:1) Soil formation2) Erosion control3) Nutirent cycling4) Storage of atmosphere carbon dioxide in biomass5) Maintence of biodiversitySustain Grasslands:1) Control the number of grazing animals, so the carry capacity dont exceeded (Rotational Grazing)2) Discourage unwanted vegetation through short-term trampling by large numbers of livestock3) Replanting barren area with native grass seeds and applying fertilizer

Parks & Nature Reserves

Grassland

Problems:1) 5% of earths land is strictly protected2) Most national parks cant sustain many large species 3) Local people trespass to search for wood, and croplandSolution:1) Add new parkland in threathen parks2) Seek private donations for parks maintenance & repairs3) Increase the number of park rangers & their pay4)Limit the number of park visitors in a crowded area 5) Protect the earth's remaining undisturbed land areas

Ecosystem Approach: is a strategy for the integrated management of land, water and living resources that promotes conservation and sustainable use in an equitable way.-->Scientists are learning how to speed up repairing operations by using approaches which includes using these measures-Restoration-Rehabilitation-Replacement-Creating artificial ecosystems

Sustain a Terrestrial Biodiversity1) Adopt a forest2) Plant trees & take care of them3) Recycle4) Buy sustainable produce wood & wood products5) Help to restore a nearby degraded forest or grassland6) Landscape your yard with plants
