Poor Fen is moderate to highly vulnerable to climate change. Increasing temperatures may lead to more water loss through evaporation, altering delicate hydrologic balances.
Increasing temperatures may lead to more water loss through evaporation, altering delicate hydrologic balances. However, with similar to slightly increased precipitation and higher groundwater recharge projected, hydrologic changes may be minimal. If water levels do rise or drop over time, sites with floating "bog" mats may be able to fluctuate naturally. Nutrient enrichment through changing land use and groundwater pollution may be one of the greatest threats and could increase non-native invasive species. However, several factors may reduce vulnerability.
