Pinecroft NAP (HR) 2006
Description:
Pinecroft NAP is the largest remaining ponderosa pine/grassland ecosystem that once was prevalent throughout the Spokane Valley, and it serves as a wildlife refuge in an urban setting. A 15 acre open area in the SE portion of the NAP was historically a bunchgrass grassland and retains a small amount of intact grassland. It is now dominated by non-native grasses and other invasive weeds, mixed with native bunchgrasses and forbs in varying concentrations. The restoration objective here is to further reduce the weed infestation and promote native grasses and forbs. This project would re-establish the native vegetation in priority portions of the 15-acre area, expanding the bunchgrass grassland on the site, reducing the risk of re-invasion by noxious weed species, and reducing the threat of this area as a propagule source of invasive species. The NAP is an ecosystem that historically had periodic low-intensity fires that burned every 5-15 years, resulting in an open pine stand with the grass and shrub understory types listed above. Fire has been suppressed for about 100 years. Overstocking of the ponderosa pine has occurred which increased the competition for limited water and nutrients. The second objective of this restoration project is to remove the heaviest concentrations of downed trees and significantly reduce the stocking level in the sapling stands (approximately 25 acres) that need thinning. This will be accomplished with contractors. Downed trees will be cut up, loaded on a truck and then disposed of off-site.
