CHAPTER 10
Across
- 6. uncut forest that has not been seriously disturbed by human activities or natural disasters for years
- 8. are unfenced grasslands in temperate and tropical climates that supply forage, or vegetation, for grazing (grass-eating) and browsing (shrub-eating) animals.
- 10. Replacing a degraded ecosystem with another type of ecosystem.
- 12. large areas of undeveloped land
- 14. Turning of a degraded ecosystem into a functional or useful ecosystem without trying to restore it to its original condition.
- 15. temporary or permanent removal of large expanses of forest
- 16. occurs when too many animals graze for too long and exceed the carrying capacity of a rangeland area
- 18. extremely hot fire that leaps from treetop to treetop
- 20. managed tract with uniformly aged trees of one or two genetically uniform species
- 23. a tree-dwelling monkey found in the forest of East Arc Mountain.
- 24. It is the process of repairing damages caused by humans to the biodiversity and dynamics of natural ecosystem.
- 25. one of the biggest problems for many parks
Down
- 1. Conservancy with more than 1 million members worldwide has created the world’s largest system of private natural areas and wildlife sanctuaries in 30 countries
- 2. corridors helps to support more species and allows migration by vertebrates that need large ranges.
- 3. zone protecting an inner core of a re-serve by usually establishing two buffer zones in which local people can extract resources sustainably without harming the inner core.
- 4. managed grasslands or enclosed meadows usually planted with domesticated grasses or other forage.
- 5. strategy where governments or private conservation organizations pay nations for concessions to preserve their natural resources.
- 7. where absence of grazing for long periods (at least 5 years) can reduce the net primary productivity of grassland vegetation and grass cover.
- 9. stand of trees resulting from secondary ecological succession
- 11. main herbivores in the Yellow stone system, are the primary food source for the wolves, but wolves also kill some moose, mule deer, and bison
- 13. most efficient way for a logging operation to harvest trees
- 17. A process wherein a degraded habitat or ecosystem is being returned to a condition as similar as possible to its natural state.
- 19. A new form of conservation biology suggested by Rosenzweig.
- 21. along with highly valuable ecological services, forests provide us with raw materials, especially ___
- 22. is classified as one of the world’s leading failing states because of fuelwood crisis
