How much is a forest worth? And how do we calculate that value? Do we simply count the trees and figure out how much we could get for them if we were to cut them down and turn them into logs, lumber, and pulp and paper?

That's been the traditional approach, but it hasn't served us well. A forest is much more than the timber it holds. A forest provides habitat for wildlife, recreational opportunities for hikers and hunters, a place for quiet contemplation, and filtration and storage of drinking water. And because forests scrub carbon dioxide from the atmosphere and store it in their trees and soils, they are a critical "hedge" against global warming.
When we take into account all of the ecological benefits, or services, a forest provides, we have to reevaluate the way we make decisions about how we manage them. Clear-cutting an old-growth forest may provide temporary jobs and profits, as well as two-by-fours to build homes and furniture, but if it also results in the release of carbon stored in the trees and soil, thus contributing to global warming, or if it wipes out the habitat of an animal that is crucial to the natural order, then the short-term gains may not be worthwhile.
Two new reports illustrate the idea of taking into account the full suite of values that a forest represents, or its "natural capital", when making decisions about resource management. Dollars and Sense: The Economic Rationale to Protect the Spotted Owl Habitat in British Columbia and The Real Wealth of the Mackenzie Region: Assessing the Natural Capital Values of a Northern Boreal Ecosystem both argue for a more holistic approach to managing our natural ecosystems.
