Alder Thicket is low to moderately-low vulnerable to climate change. Higher water levels over the long-term could convert some sites to marsh. Alder has the potential to expand as other communities decline.

More frequent large rain events could increase sedimentation and soil disturbance, leading to increases in non-native invasive species. Nutrient loading of both groundwater and surface water could also fuel invasives. Potential changes in precipitation patterns and groundwater infiltration could alter hydrologic regimes. Although Alder Thicket is generally adapted to short-term water level fluctuations, higher water levels over the long-term could convert some sites to marsh. Alder Thicket ranked as relatively adaptable, with high species diversity, a broad distribution across the state of Wisconsin, and general wide tolerance to a variety of natural disturbances. It also has the potential to expand as other communities decline and may experience a net gain in suitable habitat overall.
