- Abstract:
- The rapid and unprecedented loss of hemlock will continue to affect water, carbon and nutrient cycling at the watershed scale. Total freshwater yield will increase immediately for a sort time after the HWA infestation, but it would gradually decrease as hemlocks are replaced by deciduous trees. The combined effect of hemlock mortality and climate change will significantly alter the quantity and quality of seasonal flow regimes. The loss of hemlock will increase the total amount of nitrogen inputs to the streams with widening vernal and autumnal windows over time, but the response may be regionally - dependent (e.g. New England and southern Appalachian sites may show opposite responses).
