Simple methods for estimating the proportion of land changing from forest to nonforest are developed. Variance estimators are derived to facilitate significance tests. A power analysis indicates that 400 inventory plots are required to reliably detect small changes in net or gross forest loss. This is an important result because forest certification programs may require additional precautions w...
Problem: Most research on planning to mitigate climate change has focused on reducing CO2 emissions from coal-fıred power plants or the transportation sector. The contribution of forests to lowering net CO2 emissions has largely been overlooked. U.S. forests already offset about one eighth of the nation's annual CO2 emissions and have the potential to offset more, all at a relatively low cost. ...
Because non-industrial private forests (NIPFs) comprise over 60% of forestland, NIPF owners may substantially affect timber supply and ecosystem quality. A dynamic model shows that NIPF owners may maximize timber income despite receiving utility from nontimber goods. The model links landowners' behavior to ecosystem management by introducing the ecosystem as an alternative source of nontimber g...
“encourage economically efficient forest practices that assure the continuous growing and harvesting of forest tree species and the maintenance of forestland for such purposes as the leading use on privately owned land, consistent with sound management of soil, air, water, fish and wildlife resources and scenic resources within visually sensitive corridors as provided by ORS 527.755 that assure...
Deforestation in the tropics accounts for one-fifth of global greenhouse gas emissions. For this reason, the preservation of remaining tropical forests is an integral component of any international climate change mitigation policy. Indigenous peoples are crucial actors for the success of such a policy given the large amount of forestland in indigenous hands, their historical and cultural role i...
The evaluation of habitat quality and its genesis is great significance to ecological protection the watershed. Based on land use data, Digital Elevation Model (DEM), road network data population Cellular Automata (CA)-Markov model InVEST were used analyzed change in Wanhe Watershed, predicting 2025. this, degree degradation 2000, 2005, 2010, 2015, 2020, 2025 predicted analyzed, combined with p...
