The coefficient of variation (evaluated at a 1km spatial resolution) of topographic information acquired by two sources: (i) the 90m NASA Shuttle Radar Topographic Mission (SRTM) for those regions below 60° latitude and (ii) the 1000m GTOPO30 for those regions above 60° latitude. The dataset is currently being used in conjunction with other datasets to help characterize ecosystem properties and biodiversity within the Canadian Boreal region (Brandt, 2009).

The Dynamic Habitat Index (DHI) comprises of three indicators of the underlying vegetation dynamics derived from an annual sequence of MODIS monthly fPAR: (i) the cumulative annual greenness, (ii) the minimum level of perennial cover, and (iii) the degree of vegetation seasonality. The fPAR components were first computed for the years 2000-2005 and were then averaged to produce a long-term index of each component. The dataset is currently being used in conjunction with other datasets to help characterize ecosystem properties and biodiversity within the Canadian Boreal region (Brandt, 2009).

This dataset represents the autumn (Sept-Nov) and spring (Mar-May) seasonal snow cover over a ~10 year period for the Canadian Boreal (Brandt, 2009). It is currently being used in conjunction with other datasets to help characterize ecosystem properties and biodiversity within the Canadian Boreal region. Cited references: Brandt, J. 2009.

Fragmentation, which is often defined as the breaking apart of habitat (Fleishman and Mac Nally, 2007), represents an important aspect of the landscape spatial pattern and can greatly affect biodiversity. Specifically, forest fragmentation can be characterized by the amount and spatial configuration of forests (Wulder et al., 2009). This dataset comprises of six forest fragmentation metrics, selected from among 90 plus metrics (Wulder et al., 2008), suitable for representing forest fragmentation over large areas: (i) Edge density (m/ha), (ii) Mean patch size [ha], (iii) Number of forest patches, (iv) Proportion of forest patches [%], (v) Relative area [%], (vi) Standard deviation of patch size [ha]. These metrics...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
