<p>This strategy outlines resistance and resilience approaches to manage wetlands facing altered water budgets (water inputs, storage capacity, and outputs) due to a changing climate. Hydrology is a leading driver of wetland character and function (Cowardin et al. 1979, Brinson 1993, Tiner 2011) and so expected changes to hydrologic regimes, hydrodynamics, and water levels concern wetland managers (Erwin 2009). Projections in the Upper Midwest indicate that wetlands will be influenced both by extreme precipitation and flooding events and longer drought periods between rain events (USGCRP 2017). Some wetlands will become dryer and others may become wetter than long-term averages. Thus, managers face challenges (i.e., extreme flooding; drought) and opportunities (i.e., restored flood pulses to wetlands disconnected from surface or groundwater flows) in managing wetlands in the context of climate change (Mallakpour and Villarini 2015). Restoring hydrologic connectivity has historically been a primary tactic of management efforts to restore wetlands lost or degraded by filling or draining due to land-use conversion and water extraction (Zedler 2000), and many of those same tactics can be applied or amended by wetland managers to meet climate change adaptation objectives (Middleton et al. 2017). Restoring hydrologic connectivity and ameliorating saturated, anoxic conditions that limit decomposition also supports the capacity of wetlands to actively remove and sequester atmospheric carbon and mitigates future carbon losses (Moomaw et al. 2018).</p>
