What is a potential negative effect of drawdowns on wildlife?

The answer identifies that drawdowns can result in wildlife being displaced to less desirable locations. When water levels in aquatic environments are lowered, habitats may become less supportive for certain wildlife populations. This alteration can force animals to move away from their natural environments, where they have access to food, shelter, and breeding sites, to areas that are not as suitable for their survival needs.

For example, if a pond experiences a drawdown, the reduction in water may eliminate aquatic vegetation and diminish food sources for fish and other wildlife. As a result, those animals may be compelled to seek refuge in adjacent areas that might lack the resources they require, leading to increased competition with other species or a heightened vulnerability to predation.

The other choices suggest potential positive effects or neutrality of drawdowns, which do not accurately capture the typical ecological impact of such events on wildlife. While some wildlife may adapt or benefit from changes in habitat, the predominant concern in the context of drawdowns is often the loss or alteration of critical habitat, making less desirable locations more likely for displaced species.
