Chapter 10: Sustaining Terrestrial Biodiversity: Saving Ecosystems and Ecosystem Services
|
Section 1: What Are the Major Threats to Forest Ecosystems?
Concept 10-1A: Forest ecosystems provide ecosystem services far greater in value than the value of raw materials obtained from forests. Concept 10-1B: Unsustainable cutting and burning of forests, along with diseases and insects, all made worse by projected climate change, are the chief threats to forest ecosystems. Section 2: How Should We Manage and Sustain Forests?
Concept 10-2: We can sustain forests by emphasizing the economic value of their ecosystem services, removing government subsidies that hasten their destruction, protecting old-growth forests, harvesting trees no faster than they are replenished, and planting trees. |
Section 3: How Should We Manage and Sustain Grasslands?
Concept 10-3: We can sustain the productivity of grasslands by controlling the numbers and distribution of grazing livestock and by restoring degrades grasslands. Section 4: How Should We Manage and Sustain Parks and Nature Reserves?
Concept 10-4: Sustaining biodiversity will require more effective protection of existing parks and nature reserves, as well as the protection of much more of the earth's remaining undisturbed land area. Section 5: What is the Ecosystem Approach to Sustaining Biodiversity and Ecosystem Services?
Concept 10-5: We can help to sustain terrestrial biodiversity by identifying and protecting severely threatened areas (biodiversity hotspots), sustaining ecosystem services, restoring damaged ecosystems (using restoration ecology), and sharing with other species much of the land we dominate (using reconciliation ecology). |
