Question 1

Biological invasion by non-native species most commonly threatens native wildlife by:

Accepted Answer

Competing for resources, introducing novel diseases, and altering habitat structure

Answer

Invasive species displace natives through competition, introduce pathogens like white-nose syndrome in bats, and alter habitat (e.g., kudzu smothering forest understories) that native species depend on.

Question 2

Which remote sensing technology is most commonly used to map forest canopy structure and identify habitat features like snags and coarse woody debris?

Accepted Answer

Light Detection and Ranging (LiDAR)

Answer

LiDAR uses laser pulses to create three-dimensional point clouds that accurately characterize canopy height, vertical structure, and ground-level features relevant to wildlife habitat assessment.

Question 3

The 'umbrella species' concept in conservation planning proposes that:

Accepted Answer

Protecting habitat sufficient for a wide-ranging species will incidentally conserve many co-occurring species

Answer

Umbrella species require large habitat areas with specific ecological conditions, so managing for their needs inadvertently protects the habitat and biodiversity of many other associated species.

Question 4

What is the primary ecological rationale for maintaining large diameter trees and old-growth structural features in managed forests?

Accepted Answer

Providing unique microhabitats like deep bark furrows, large cavities, and epicormic branches used by wildlife

Answer

Large old trees develop structural features — deep bark for invertebrates, large cavities for owls and martens, and platform branches for raptors — that younger trees cannot provide.

Question 5

Which federal agency is primarily responsible for managing wildlife on National Forest System lands?

Accepted Answer

U.S. Forest Service within USDA

Answer

The U.S. Forest Service manages wildlife habitat on National Forests, while states retain jurisdiction over wildlife populations, and USFWS handles threatened and endangered species.
