Background: Historical forests (circa 1799 to 1846) of Indiana were predominantly composed of American beech (25% of all trees) and upland oaks (27% of all trees). I compared historical forest composition, using studies of smaller areas to approximate composition for uncommon species or genera (
Exotic grass invasions are often facilitated by disturbances, which provide opportunities for invasion by releasing pulses of resources available to invaders. Where disturbances such as prescribed fire are used as a management tool, there is a pressing need to identify ecosystem attributes associated with susceptibility to disturbance-induced invasion.
Many potential geographic information system (GIS) applications remain unrealized or not yet extended to diverse spatial and temporal scales due to the relative recency of conversion from paper maps to digitized images.
Wildlife biologists classify some bird species as early successional because of apparent dependence on early successional vegetation such as forbs, grasses, shrubs, and small trees.
During a 3-y seed increase project, taproot size (volume and biomass) of showy milkweed (Asclepias speciosa Torr. [Asclepiadaceae]) increased annually, although top diameter of the taproot remained constant after the first growing season. At the end of the third year, taproots were harvested, held under different cold storage treatments, and subsequently outplanted.
The number of global initiatives for forest restoration, and the scope of these initiatives, continues to increase. An important tool for meeting objectives of these global initiatives is reforestation, achieved by natural processes or by tree planting. Worldwide, organizations are challenged to most efficiently and effectively direct resources to the most critical reforestation needs.
Residents in the wildland-urban interface (WUI) can play an important role in reducing wildfire’s negative effects by performing wildfire risk mitigation on their property. This report offers insight into the wildfire risk mitigation activities and related considerations, such as attitudes, experiences, and concern about wildfire, for people with homes in select communities in Montezuma County, Colorado.

This report offers insight into the wildfire risk mitigation activities and related considerations, such as attitudes, experiences, and concern about wildfire, for people with homes in the Pagosa Fire Protection District of Archuleta County, Colorado.
We conducted this assessment to provide information on the current conditions of riparian and wetland ecosystems in reference to their natural range of variability on the Manti-La Sal National Forest during forest plan revision.
