Ecologist use various population sampling techniques to estimate the population size of different species including probability sampling, where every individual in the population has an equal chance of being researched and non-probability sampling, members of a population don’t have an equal chance of being researched.
Population sampling techniques used to estimate the size of my animal are random sampling, ratified sampling, cluster sampling, and systematic sampling.
Since a large number of organisms are found in Class I, we know the stream has good water quality.
The above stream conditions affects the woodchuck by providing it with a good water drinking source.
The woodchuck and the ecosystem would be affected if the majority of the organisms found were in class III because the poor water quality would not provide a source of drinking water for the woodchuck to live.
The stream would provide a source of drinking water for the woodchuck but it wouldn’t benefit off of the marsh and mine.
Good soil conditions provide the woodchuck with plants to eat.
Factors that negatively affect the riparian ecosystem are Abandon Mine Drainage and agricultural runoff in streams, fertilizers on grasses affect the soil. Ways to conserve and preserve the riparian habitat are to not use fertilizers and other chemicals that could harm it. These factors affect the woodchuck negatively by causing a lack of fresh water to drink from and plants that may harm them.
