We present a modeling framework for simulating afforestation, deforestation and sustainable forest management that is composed of an interlinked economic model and a spatially explicit forestry model. The linkage of models allows addressing a number of important issues relevant to REDD+, in particular, estimation of cross-country comparable CO2 mitigation potential for individual countries and ...

Riparian areas are critical interfaces between aquatic and terrestrial ecosystems. Protecting and enhancing them by implementing streamside management zones (SMZs) is an essential practice of sustainable forestry. SMZs provide ecological functions including protection against non-point source pollution, promotion of water infiltration, contribution of beneficial nutrients and coarse woody debri...

Forest harvest planning and scheduling problem is an important part of forest resource management. It is a complex task requiring expertise and integration of multidisciplinary elds. We review mathematical programming as applied to forest harvesting problem. The review suggests that long term scheduling is diicult because of the prohibitive size of the model. Such long term scheduling allows on...

Between April 2000 and March 2007, the Canadian Ecology Centre – Forestry Research Partnership funded, directed, or catalyzed approximately 145 projects. Most of these focused on knowledge and data acquisition, providing a solid foundation for a series of sensitivity and gap analyses to determine whether a long-term goal of enhancing productivity on 6 forest management units in Ontario was achi...

Environmental policies in the United States and abroad are reducing timber harvests while wood demand is mounting. Reduced harvesting on public lands means that privately owned lands will be managed with greater intensity in the United States and that wood will be imported from other nations lacking strong environmental safeguards. It is imperative, therefore, that both public and private fores...
