Carbon sequestration is an emerging forest management objective within California and around the world. With the passage of the California’s Global Warming Solutions Act (AB32) our need to understand the dynamics of carbon sequestration and to accurately measure carbon storage is essential to insure successful implementation of carbon credit projects throughout the State. As the leader in fores...

The forest products industry is a major component of Mississippi’s economic base. The need for a county-level forest inventory and the availability of decision support tools for locating forest product mills are of primary importance in attracting and sustaining the industry. The objective of this paper is to describe the pilot study, currently under development, for an integrated decision supp...

The reusability of decommissioned treated wood is primarily dependent on the residual strength of the wood after service. Determining the residual strength can provide useful information for structural design and reuse of the decommissioned treated wood. This study evaluated the residual strength of decommissioned chromated copper arsenate-treated utility pole wood. Eleven decommissioned southe...

Wood biomass has been viewed as “carbon neutral”—its uses as energy have a zero carbon footprint. Some observers argue that the use of wood biofuels will result in a decrease of the forest stock and a net reduction of the carbon captured in the forest. Such assessments take a static, accounting view of forest systems and do not consider the effects of management in renewing the forest and incre...

To satisfy the increased demand for forest products, much of the future timber supply is expected to be derived from improved trees grown on managed plantations. This fast-grown resource will tend to be harvested in short-age rotations and will contain higher proportions of juvenile wood compared with wood in current harvests. As a result, current allowable properties may need to be reduced in ...

We evaluated the conservation attitudes of the local villagers living adjacent to the Kalakad-Mundanthurai Tiger Reserve in southern India 6 years after implementation of a World Bank funded eco-development project. We assessed attitudes towards three facets of conservation: the tiger, an emblematic species signifying India's commitment to wildlife conservation; the forest, a principle source o...

Instream processing may substantially alter nutrient export from forested watersheds. This study tested how instream uptake of N and P were affected by successional differences in the accumulation of large wood and debris dams in a 66-year chronosequence formed by five watersheds within the Hubbard Brook Experimental Forest (HBEF), NH. Nutrient enrichment releases in summer 1998 were used to me...

Sweden belongs to an exclusive group of nine countries in the world with a forest cover greater than 65% of the land area. Forest products make a large proportion of Sweden’s net export income. Not only wood fibres but also berries and meat from the forests are important. Game hunting, reindeer farming, berries and mushroom gathering, as well as fresh water fishery, are all included in human fo...
