Sedimentary Foothills Soil Survey Update Project, 2019 and 2020

Conducted by UDSA-NRCS, Fort Collins MLRA Office
Soil Scientists, Kari Sever and Chris Fabian

Project Summary:
MLRA subset: 49C-NCSF. Northern Colorado Sedimentary Foothills
Current MLRA: 49. Southern Rocky Mountain Foothills
Counties: Larimer, Boulder, Jefferson Counties, Colorado
Geology: Dominantly Mesozoic Sedimentary Formations.
Landscape/Landforms: Hogbacks and Homoclinal ridges that have been tilted by the formation of the Rocky Mountains. In addition, fans, terraces and other landforms created by transported materials associated or co-located with the Hogbacks and Homoclinal ridges are included in this update.
Acres: Approx. 197,000 spatial acres. MU's to be evaluated are 211,270 acres, but not all map unit acres may occur in final project.
Vegetation: Grasslands, Shrub-grasslands and Ponderosa Pine Savanah
Precipitation: 305-483mm (12-19in)
Approx. Workload: 2.2 person years (2019-2020)

Scope: A complete evaluation and update. Poorly defined map units updated (miscellaneous map units and map units named at the suborder, great group and subgroup taxonomic level) will have priority depending on the land use potential. In addition, conventional map units with high demand for interpretations will be investigated. Map units found to be currently meeting interpretive needs will require less investigation.

Project Description:
A soil survey is carried out by soil scientists who traverse the land on foot to examine the soil in detail. The soils data is recorded and entered into a national soils database, where it is merged with spatial data (digital maps). The soil maps show where the different soil types are located, and the database provides soil property information along with the suitabilities and/or limitations of the soil. The completed product, the Soil Survey of Larimer County, is published to Web Soil Survey (WSS). The WSS is updated yearly with the most current soils data and is free to the public. WSS can be accessed at https://websoilsurvey.nrcs.usda.gov/.

The soil survey is a tool that can be used in many assessments and design decisions, including park site management plans, erosion control, garden design, ecosystem restoration, water conservation plans, waterway restoration, flood risk management, and recreation use planning.

Soil survey update entails describing the soil and its properties to a depth of 5 to 7 feet (if feasible) by hand-digging or hand-augering with a 3” diameter auger. If we are working on turf, we place the sod and soil material on tarps so that it is easy to backfill the hole and replace the sod on top when we are finished. We do our best to keep the area looking like it was before we were there and practice “leave no trace” etiquette.

The original field work for the soil survey of Larimer County occurred in the 1960s and 70s. The Sedimentary Foothills Soil Survey Update Project will update the existing soil maps and the new data will be posted to the national database. In addition to possible changes in soil properties, the update process will capture changes in land use and land cover and will provide more accurate interpretation products to the public.

Current field work is underway in other parts of the Foothills, but the project will be carried out through 2020. If we have good contact information, we can let the property owner/operator know (via text, phone and/or email) on a daily basis, if necessary, when and where we will be planning to access your property. Also, if you’d prefer, I’d be happy to meet with you to show you targeted sample locations on my computer.

At this time, I'm requesting your participation in the Larimer County soil survey update, which will require access to your property.
