Greene, John L.; Siegel, William C. 1994. The status and impact of state and local regulation on private timber supply. General Technical Report RM-255. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Forest and Range Experiment Station. 22 p. State and local regulatory enactments that affect private forest management are identified and summarized. The results o...

This paper challenges common assumptions about convexity in forest rotation models which optimize timber &s nontimber benefits. If a local optimum occurs earlier than the globally optimal age, policy based on marginal incentives may achieve suboptimal results. Policy-relevant nonconvexities are more likely if (i) nontimber benefits dominate for young stands while the optimal age depends primari...

Timber market analysis of the South’s predominantly private timberland finds that the 13 southern states produce nearly 60 percent of the nation’s timber, an increase from the mi dmi d1900s. Projections with the Subregional Timber Supply model show that, despite a 67 percent increase in the area of pine plantations, the South will experience a 2 percent decline in private timberland area as oth...

At the Amazon estuary, the oldest logging frontier in the Amazon, no studies have comprehensively explored the potential long-term population and yield consequences of multiple timber harvests over time. Matrix population modeling is one way to simulate long-term impacts of tree harvests, but this approach has often ignored common impacts of tree harvests including incidental damage, changes in...

BACKGROUND The focus of REDD+ is sensu stricto on maintaining forest carbon stocks. We extend the scope of sustainable management of forest from forests to timber utilization, and study carbon offsets resulting from the utilization of harvested timber for bio energy or harvested wood products (HWPs). The emission budget of harvesting operations depends on the loss of standing biomass by timber ...

Neural networks are a powerful tool used to model properties and behaviour of materials in many areas of civil engineering applications. In the present paper, the models in artificial neural networks for predicting the temperatures in timber under fire loading have been developed. For building these models, training and testing using the available numerical results obtained using design methods...

AB S T R A C T . Community stability is an objective of USDA Forest Service timber sales. This paper examines that objective, and the success the Forest Service can have in attaining it, through its intended maintenance of a constant volume timber harvest schedule. We apply a three-factor, two-sector modified general equilibrium model with empirical evidence from the timber-based counties of we...

All opinions expressed here are those of the authors and not those of the Economics Education and Research Consortium Research dissemination by the EERC may include views on policy, but the EERC itself takes no institutional policy positions Though Russia is very rich in natural resources, the share of natural resource rental payments in budget revenues is very low, less than 4% of the consolid...

After being envenomated by the timber rattlesnake, a patient was found to have a platelet count of 5000 per microliter, prothrombin time and activated partial thromboplastin time both greater than 150 sec, plasma fibrinogen 0 mg/dl, and fibrinogen split products 2560 microgram/ml. However, this patient did not appear to have acute disseminated intravascular coagulation since coagulation factors...

Indonesia’s forestry sector is in a dilemma due to the long-standing disparity between high processing capacity of forest industries and the limited supply of timber. The supply crunch has led to over-harvesting in order to meet demand and resulted in a decline of natural forests. The Indonesian government seeks to revive the forestry sector and secure its long term survival through a massive t...
