Ground Disturbance and Downed Woody Materials following Diverse Timber-Harvest Methods in the Pockwock Watershed

The forWater Network, funded by the federal government as well as industry partners and provincial governments, is a national research network looking into the impacts of forest-management strategies on drinking-water source quality and treatability. forWater Network researchers at Dalhousie University (including Duinker, the supervisor in this application) are working with Halifax Water and Westfor Management Inc. to determine how the Pockwock forested watershed can be managed to improve water treatability. A key issue here is the movement of dissolved organic carbon (DOC). DOC movement from the land to the water has increased in recent decades, and that increases the cost of treating drinking water to acceptable standards. The Halifax study centres on integrated simulation modelling to build and analyze long-term scenarios of forest management and climate change and their effects on DOC levels in Lake Pockwock. The modelling is supported by monitoring of water moving through the forested landscape as well as detailed measurements of the carbon stocks in the forests themselves. Experimental timber harvests will reveal what happens to DOC movements under different harvest regimes. With the project proposed herein, we intend to make a thorough characterization of two additional important variables in forest carbon assessment:
