Summary Introduction
Introduction: The decline-population approach is a method, which involves the identification of the declining population, determination of the environmental factors that resulted in the population decline, and then it takes remedial actions. There are certain factors that cause the population to decline and it includes habitat loss, pollution, and climate change.

A biologist determines the growth rate of a population of 198 frogs in a marsh near
Beaverhill Lake, Alberta, to evaluate the quality of the environment. The researcher finds
that, in one year, 34 were born, 86 died, 12 migrated into the marsh, and there was no
emigration.
a. frogs are considered an indicator species for the quality of the environment. Determine whether the growth rate of this population in one year is a cause for concern. if so, what might the concerns be?
All of the following strategies would potentially help restore populations of wild salmon except
Group of answer choices
a)planting vegetation along the sides of streams.
b)fencing areas along stream where cattle graze.
c)removing wood from streams to allow access for spawning adults.
d)increasing education about water pollution.
