Assessing the Condition and Sustainability of the Trail System at Tallgrass Prairie National Preserve

This research assessed the condition and sustainability of the trail system at Tallgrass Prairie National Preserve, a National Park Service unit that partners with The Nature Conservancy (TNC) in the management of this unit.

by U.S. Geological Survey

The Preserve was created through a 10,862-acre TNC land purchase in 2005 which included a “legacy” system of primitive unsurfaced ranching roads. The objectives of this study included assessing the sustainability of the trail system (including trail grades and alignments relative to the topography), its current resource conditions, an inventory of trail system features (stream crossings, gates, signs, culverts), and suggestions to improve trail system sustainability and ability to accommodate increasing use and additional uses such as horses and mountain bikes.

Fieldwork was performed in May 2022, with three field staff driving or walking all system trails to collect georeferenced data and photographs. The field assessment manual (Appendix 1) describes data collection protocols, and all collected data were recorded using a cell phone app (Fulcrum), with data transferred to Excel and ArcGIS Pro for analyses. Additional GIS analyses were conducted using accurate LiDAR Digital Elevation Model (1x1m resolution) topography data to analyze trail grades and landform alignment angles for the entire trail system in 10 ft cells. All georeferenced project data in GIS formats with metadata are a product of this research, in addition to this final report.

Building a Permeable, Low Maintenance Recreational Trail Along a Shoreline

posted Apr 7, 2023

In 2009, the city of The Colony planned to build a recreational trail (10 foot-wide, 3.5 mile pathway) that would run along the lake’s shoreline, contouring to its natural shape and providing residents with a picturesque route for outdoor activities such as walking, jogging, and cycling. The city selected the GEOWEB® Soil Stabilization System due to its flexibility to conform to curves, surface permeability, and low maintenance design.
