This dataset identifies possible old-growth forest habitat in southern Appalachian National Forests. It includes information on forest type and timber management suitability. Old growth was identified in 1996 by the Southern Appalachian Man and the Biosphere Program (SAMAB) under the Southern Appalachian Assessment (SAA), using the National Forest System Southern Region's Continuous Inventory of Stand Condition data. The Conservation Biology Institute (CBI) acquired the dataset with limited metadata in March 2008. Existing metadata and attribute values were revised by CBI using SAA report documents (http://samab.org/saa/saa_reports.html). For more information on how this dataset was developed, please refer to the...
This dataset represents the composite score of watersheds for redwood conservation across multiple criteria compiled by the Conservation Biology Institute for the report "A GIS-based model for assessing conservation focal areas for the redwood ecosystem." Underlying criteria include late successional patch size, concentration of late successional patches, road density, location of imperiled species, forest neighborhood age, forest fragmentation, potential connectivity to existing protected areas, road/stream intersections, and forested riparian zones. For more details, see the full report at http://consbio.org/products/reports/a-gis-based-model-for-assessing-conservation-focal-areas-for-the-redwood-ecoregion. This...
The rasters 22 classes of forest vegetation from potential forest (value 1) through large multistory conifer (value 22) plus water, barren lands, etc. at 25 meter resolution. Source data was Interagency Vegetation Mapping Project (IVMP) coverages for quadratic mean diameter (QMD), stand structure, and conifer vegetation from Landsat TM ca. 1996. Accuracy Assessment not valid for land areas smaller than physiographic province. Mapped by the Regional Interagency Effectiveness Monitoring Program, NW Forest Plan, R6/PNW in 2005. LANDSAT TM ca. 1996; IVMP quadratic mean diameter, species, canopy structure

This cooperative effort by USDA Forest Service Research and the National Forest System assesses the state of knowledge related to the conservation status of four forest carnivores in the western United States: American marten, fisher, lynx, and wolverine. The conservation assessment reviews the biology and ecology of these species. It also discusses management considerations stemming from what is known and identifies information needed. Overall, we found huge knowledge gaps that make it difficult to evaluate the species' conservation status. In the western United States, the forest carnivores in this assessment are limited to boreal forest ecosystems. These forests are characterized by extensive landscapes with...

Legally established and spatially defined areas of old growth forest that are identified during landscape unit planning or an operational planning process. Forest licensees are required to maintain legally established OGMAs when preparing FSPs. OGMAs, in combination with other areas where forestry development is prevented or constrained, are used to achieve biodiversity targets. This spatial view will show the most current polygons and excludes sensitive information. This Legal 'Current' layer is freely downloadable.
This dataset depicts portions of late seral forest (from the ForestCover grid) that are on privately owned lands for the Klamath-Siskiyou ecoregion. Only forest that was greater than 200 years old was included. Cell resolution is 30 m. Forest cover was determined using Landsat 7 ETM+ imagery from mainly summer 2000 and some from 1999. The remote imagery analysis was conducted by Hong Jiang and Jim Strittholt at Conservation Biology Institute. Cell resolution is 30 m. In 1999, the Conservation Biology Institute (CBI) concluded a conservation science assessment of the Klamath-Siskiyou ecoregion culminating in the report “A Science-based Conservation Assessment for the Klamath-Siskiyou Ecoregion.” Numerous ecological...
This layer represents the remaining late seral forest fragments within the original distribution of the coastal temperate rain forest. Excerpt from "The Rain Forests of Home: An Atlas of People and Place. Part 1: Natural Forests and Native Languages of the Coastal Temperate Rainforest" (p. 13): Analysts determined the extent of the remaining undeveloped forest by subtracting a GIS layer representing areas primarily affected by human activity from the layer of original forest distribution. The "human development" layer was assembled from sources giving some indication of areas primarily affected by farming, logging, or urban development. These sources included forest and vegetation classification data sets as well...
This dataset was used as part of a continent-wide analysis of tree fecundity and its association with climate and tree size. This dataset consists of: plotinfo.csv, which contains basic attribute information for the field plots where the data were collected; seeddata.csv, which contains the data for seeds collected (how many, what type, etc.); trapxycoord.csv, which contains location and identification information for the seed traps used to collect the seeds; treexycoord.csv, which contains location and attribute information for the standing trees in the plot where the seeds were collected; and treedata.csv, which contains data on the size and species of standing trees in the plot where the seeds were collected.
