PCEI is working with the Idaho Transportation Department (ITD) on the
mitigation and propagation of Spalding's catchfly, Silene
spaldingii, a threatened plant. During the Idaho Highway 95
expansion, a small population of Spalding's catchfly was destroyed. To
mitigate for the loss, ITD hired PCEI to collect and propagate the
plant in the PCEI Learning Nursery. The propagated plants will then be
used for restoration and recovery of the species. The existing roadside
Spalding's catchfly site will be rehabilitated through weed control and
native bunchgrass restoration to promote the re-establishment of the
Spalding's catchfly.
