Ecology Quiz

Open prairies or grasslands with scattered groves of trees.

• Savannas

• Closed Canopy forests

• Old Growth forests

• Monoculture forestry

Forests free from disturbance for long enough (generally 150 to 200 years) to have mature trees, physical conditions, species diversity, and other characteristics of equilibrium ecosystems.

• Savannas

• Closed Canopy forests

• Old Growth forests

• Monoculture forestry

Harvesting only mature trees of certain species and size; usually more expensive than clear-cutting but less disruptive for wildlife and often better for forest regeneration.

Mature trees are removed from the forest in a series of two or more cuts, leaving young trees and some mature trees as a seed source for future regeneration.
