CH9 Habitat Corridors

Question 1

What are the potential benefits of habitat corridors?

Answer 1

-Habitat corridors: connections that allow migration between reserves.
-Allow migration and gene flow

Question 2

How does a strip corridor differ from a line corridor?

Answer 2

-Line corridor: Consists entirely of edge habitat, allow passage under/over roads, etc. (quick pass through for animals)

-Strip corridor: Broader, contain some interior habitat with intact functioning communities (may be
several hundred miles wide, and species may take their time passing through due to viable habitat)

Question 3

How would you classify the corridor established for the pronghorn sheep?

Answer 3

line corridor (use fences to direct them)

Question 4

What potential drawbacks do corridors have in a management scheme? What is the opportunity cost of establishing them?

Answer 4

-Spread of disease
-Vulnerability to hunters and predators
-Opportunity cost: Money used to establish corridors could be used to buy more land to form additional reserves.

Question 5

What type of data would you need to justify and locate a habitat corridor?

Answer 5

• Know their normal migration routes
  -high number of accidents (corridor can decrease risk - safer)

Question 6

How could climate change affect the need to build habitat corridors?

Answer 6

So they can get to cooler places, migration.
