Potential changes in precipitation patterns and groundwater infiltration could alter hydrologic regimes. Tamarack and many of the dominant tree species are projected to decline, although red maple may be more adaptable. However, tamarack is a pioneer species and has the ability to regenerate rapidly when conditions are favorable, and the community may persist in more northern sites or in climate refugia. It will likely fare less well in southern locations and in isolated stands in fragmented landscapes with limited connectivity to other natural communities. Relatively high diversity of other shrubs as well as red maple may offer opportunities for facilitated transformation to shrub-carr or hardwood swamp, maintaining a native wetland community, at least in sites not overrun by invasive species such as glossy buckthorn and reed canary grass.
