The source of this coverage data set is the fish biodiversity maps created for The Nature Conservancy (TNC) as part of their Hexagon Project. Professor Peter Moyle and his graduate student, Paul Randall, of the Department of Wildlife and Fisheries Conservation Biology at the University of California, Davis were hired to produce range maps for all known fish species that presently occur in California. Each coverage denotes a separate fish species (refer to the species coverage key below). The polygons are estimated to be accurate at a scale of roughly 1:1,000,000.

In planning conservation and restoration projects, it is helpful to know where and what has been done in the past. Three databases of restoration projects, totaling 451 projects are included in this dataset. These projects were completed in the mid-1990s by the CA Fish and Game Department, US Fish and Wildlife, Bureau of Land Management and the Forest Service. This information is by no means complete, and ideally a database that includes all projects completed in the last couple of decades would be available for an analysis of restoration project prioritization. Restoration projects are often undertaken without an examination of the degree of success of prior projects. Developing sub-basin databases of past and...
This dataset represents watersheds with low stream continuity. The full Preliminary Aquatic Assessment for the Lower/Middle Klamath and Upper Sacramento Rivers and related datasets can be viewed in a gallery at: http://app.databasin.org/app/pages/galleryPage.jsp?id=c0b34c4e1f7c405fab4829d4fd56b36d
Percent forest cut (1972-1992) in watersheds of the Lower/Middle Klamath and Upper Sacramento Rivers
The percent of forest cut was determined for each watershed using the land use change dataset developed at Conservation Biology Institute and available at: http://app.databasin.org/app/pages/datasetPage.jsp?id=4d1c4f5a049b4888b1f7fe35c09bfaee
The 2000 Rogue River aquatic integrity analysis used road density, road-stream intersections, forest change and fish barriers as surrogate indicators of watershed integrity. High road density contributes to increased levels of erosion and sedimentation and consequent alterations to hydrological patterns and degradation of water quality (OCSRI 1997). In addition, watersheds with higher road densities provide easier human access and are correlated with higher levels of disturbances from human activities that degrade water quality and aquatic habitat integrity (Frissell et al. 1996, Roth et al. 1996).
A total of the mineral locations from the Mineral Availability System and Mineral Industry Location data layer (EPA BASINS) was summed within each CALWATER planning watershed and then divided by the watershed area to normalize the data and account for the variation in size of the planning watersheds. Figure 7 illustrates the primary mineral commodity for each mineral location and the mineral location scores.

The assessment of ecological integrity remains a primary component of present-day conservation strategies for freshwater ecosystems, but approaches vary widely in method, scale, efficiency, and sustainability. The need for standardized assessment practices have been noted in several national conservation initiatives. The range of approaches under development or in use by LCCs and partner agencies offered a timely opportunity to summarize the range of approaches, identify data that would facilitate particularly promising methods, and evaluate the success with which assessments are currently integrated into broad conservation planning and management. The investigators goals for this project were to provide LCCs and...
