- 10. The number of wildlife each habitat can support throughout the year.
- 11. recommended to remove some trees when competition slows the growth of all trees.
- 14. the best land for the most intensive cultivation of field crops with the fewest limitations and can be planted year after year.

Down
- 1. No area of U.S. land is more important to wildlife, land that is poorly drained- swamps, bogs, marshes, etc
- 2. the tendency of soil particles to cluster together and function as soil units called aggregates that leave pore space to store air, water, nutrients, and allow root penetration
- 3. water that plant roots can absorb.
- 6. used to reduce the risk of wildfires by eliminating forest litter (fuel).
- 7. smallest soil particle
- 9. Largest soil particle
- 12. the cycling of water between water sources, atmosphere, and surface areas.
- 13. very steeply sloping and best used for planting trees.
- 15. scientific forest management techniques
- 17. Intermediate sized soil particle
- 19. The rate of movement of air and water through the soil
- 24. associated with sandy soils.
- 26. space to store air, water, nutrients, and allow root penetration.
