Curlew National Grassland Restoration Project

After nine years of highway reengineering, conservation planning, archeological protection, nonprofit partnerships, and extensive research, the beautiful seed of wetland restoration was planted this week at the Curlew National Grassland in southern Idaho! What exactly does this mean? It means, 3,400 perfect graminoid starts were planted along one mile of Rock Creek to establish a strong streambank stocked with native plant species. With the proposed reconstruction of highway ID-38 back in 2010, the Caribou-Targhee National Forest hydrologist, forest botanist, Rose Lehman, and many other partnered to establish a strategy that ensured the structural integrity of this location in the Curlew (see photo below). This meant a variety of regulations and compromises such as: upsizing culverts, avoiding stream meanders and/or natural springs, and Native American lands.

Two Idaho native graminoids were chosen for streambank stabilization: Nebraska sedge (Carex nebrascensis) and Baltic rush (Baltic balticus). The planting took a total of two days. Co-intern, Olivia Turner, five volunteers from the Sagebrush-Steppe Landtrust in Pocatello, ID, two hydrologists, and myself gathered together for the second day of the project. Buckets filled with plant starts and shovels in hand, we successfully spread out along the parameter of the stream. Each 2-person team would simply create holes in the mucky Idaho clay and ease every juvenile into the soil. The ground along the stream is incredibly moist and idealistic for these younger individuals. So ideal that the estimated regenerative success rate is 90% for this particular project area! That would promote roughly 3,060 individuals to take root and thrive!

The project was a complete success. The day was filled with affirmation for the future of this particular site. It was a wonderful experience to step aside from SOS and terrestrial botany for a moment and participate in wetland restoration. The future of this project paints the picture of a lush wetland habitat filled with native sedges and rushes, a running stream, moose in the willows, and the pink flowers of mallow blooming.
