Soil Survey and Ecological Site Projects at Hovenweep and Capitol Reef National Parks

This document summarizes the soil survey activities and ecological site descriptions initiated in Hovenweep National Monument and Capitol Reef National Park. The average annual precipitation ranges from 6 to 30 inches, primarily on the drier side, influencing soil moisture regimes. Ongoing projects include drafting reports, reconnaissance of riparian areas, and detailed mapping for hydrologic modeling. Key soil types evaluated include Mellenthin very gravelly loam and Klondike sandy clay loam, among others. Upcoming assessments and collaboration projects with various groups are also outlined.

  7. Current Projects

  8. Soil Survey Manuscript • Completed English Edit Ecological Site Description Report • Currently at English Edit Hovenweep National Monument

  9. Capitol Reef National Park • Spatial and Attribute data are posted to WSS • Digital Map Finished Product is complete • Draft Manuscript has been circulated • ESDs are in draft form awaiting approval • ESD report is in draft form

  10. Held Scoping Meeting in April Research Permit Obtained Reconnaissance of riparian areas started in August Premapping started Zion National Park

  11. Mapping Considerations • More detailed mapping in high use areas • Detailed mapping on private inholdings • Note springs and related soils • 1 mm (#100) sieve data needed for hydrologic modeling • Surface and first underlying horizon • Prefer to store in NASIS Zion National Park

  12. FY 14 • Complete QC report • Submit draft series • Complete manuscript • QC Spatial data • Submit for Correlation Kane County Soil Survey

  13. Submitted for approval • Mellenthin very gravelly loam, 1 to 25 percent slopes • Klondike sandy clay loam, 2 to 15 percent slopes • Other potential projects • Gypsiorthids-Gypsiorthids, shallow complex, 1 to 50 percent slopes • Showlow very cobbly clay loam, 1 to 15 percent slopes SDJR Projects

  14. SDJR Projects

  15. Henry Mountains Cooperative ESD Project • Data is being evaluated • Shale/Saltbush ESD Re-evaluation • Tarantula Mesa Soil Climate Re-evaluation • Will be proposed • Washington City Hydrologic Group Project • TSS project Other Projects
