Question

the u. s. forest service notes that the fire suppression policies of the last century were as damaging to the kirtland's warbler population as ddt was to the bald eagle. how can extinguishing a wildfire be a listing factor to this bird's populations? all but one could apply.

Answer 1

The fire suppression policies of the last century and DDT have had negative impacts on the Kirtland's warbler and bald eagle populations, respectively.

Step-by-step explanation:

The fire suppression policies of the last century were detrimental to the Kirtland's warbler population, just like how DDT was harmful to the bald eagle. Extinguishing wildfires can be a contributing factor to the decline in Kirtland's warbler populations because these birds depend on specific habitats created by periodic wildfires. When wildfires are suppressed, their habitat becomes overgrown and unsuitable for the birds, leading to population declines.

Answer 2

The correct answer is A) They reduce the availability of jack pine habitat, which is essential for the Kirtland's warbler's nesting and breeding success.

How to extinguish wildfire?

Kirtland's warblers are a specialized species that rely on young jack pine forests for nesting and breeding. These forests are created by wildfires, which clear away older trees and create the open, sunny conditions that jack pines need to grow.

However, fire suppression policies have reduced the frequency and intensity of wildfires, leading to a decline in young jack pine forests. As a result, Kirtland's warblers have had difficulty finding suitable nesting habitat, and their populations have declined.

A) They reduce the availability of jack pine habitat, which is essential for the Kirtland's warbler's nesting and breeding success.

B) They increase the amount of competition from other bird species.

C) They increase the risk of predation.

D) They increase the risk of disease.
