Research on community forests, primarily governed and managed by local forest users, in the United States is limited, despite their growth in numbers over the past decade. We conducted a survey to inventory CFs in the U.S., and better understand their ownership and governance structures, management objectives, benefits, and financing....
Research Summary: Private correctional firms are political actors. They work to create favorable conditions to market their services. At the same time, they are constrained by external political forces, including political parties, social movements, and public opinion. This article reviews what we know about the reciprocal relationship between the private...
US forestlands are increasingly subject to disturbances including wildfire, insects and disease, and urban and exurban development. Devising strategies for addressing these "forest threats" depends on anticipating where individual disturbances are most likely and where they might occur in combination. However, many spatial data sets describing forest threats are produced...
Computing resources donated by volunteers have generated the first superensemble of regional climate model results, in which the Hadley Centre Regional Model, version 3P (HadRM3P), and Hadley Centre Atmosphere Model, version 3P (HadAM3P), were implemented for the western United States at 25-km resolution. Over 136,000 valid and complete 1-yr runs...
Disturbance events strongly affect the composition, structure, and function of forest ecosystems; however, existing US land management inventories were not designed to monitor disturbance. To begin addressing this gap, the North American Forest Dynamics (NAFD) project has examined a geographic sample of 50 Landsat satellite image time series to assess...
Forest-fire policy of U.S. federal agencies has evolved from the use of small
patrols in newly created National Parks to diverse policy initiatives and institutional arrangements
that affect millions of hectares of forests. Even with large expenditures and
substantial infrastructure dedicated to fire suppression, the annual area burned by wildfire...
Spatial climate datasets of 1981–2010 long-term mean monthly average dew point and minimum and maximum vapor pressure deficit were developed for the conterminous United States at 30-arcsec (~800m) resolution. Interpolation of long-term averages (twelve monthly values per variable) was performed using PRISM (Parameter-elevation Relationships on Independent Slopes Model). Surface stations...
The management of fire-prone forests is one of the most controversial natural resource issues in the US today,
particularly in the west of the country. Although vegetation and wildlife in these forests are adapted to fire, the
historical range of fire frequency and severity was huge. When fire regimes are...
Phytophthora infestans, the causal agent of late blight disease, has been reported in North America since the mid-nineteenth century. In the United States the lack of or very limited sexual reproduction has resulted in largely clonal populations of P. infestans. In 2010 and 2011, but not in 2012 or 2013,...
