Wet and wet-mesic prairies are moderately vulnerable to climate change. These ecosystems are tolerant of a broad range of climatic conditions. Altered seasonal precipitation and the resulting hydrologic responses pose the greatest climate-related threats.

Wet prairie is moderately vulnerable to climate change (when evaluated in low to high climate change emissions scenarios). Wet Prairies may be most vulnerable to changes in hydrology, increasing non-native invasive species, and invading brush. Changes to surface water hydrology are likely to occur with climate alterations to the hydrologic cycle. Thus leading to projected increases in droughts as well as the frequency and intensity of flood events. Sites that are lower in the watershed may be more vulnerable due to the greater likelihood of flooding and associated nutrient-laden run-off, sedimentation, and transport of invasive species propagules. Non-native invasives and brushy species may also benefit from nutrient enrichment and longer growing seasons. Groundwater levels may increase or decrease, depending on the relative influence of numerous factors such as more precipitation in winter and spring, summer drought, and increased water withdrawals for human uses. Increasing frequency and intensity of flooding is also a major concern. The windows of opportunity for prescribed burning may contract or shift to different times of year due to changing conditions (e.g., wetter springs and earlier spring green-up). Lack of fire contributes to shrub invasion in Wet Prairies. Sites with the highest adaptive capacity may be those that are large, occur high in the watershed, have intact hydrology, are buffered from the negative effects of runoff and sedimentation, are juxtaposed with other high-quality wetlands, and have high species diversity.
