 
Pinyon-juniper woodlands are most often represented as a gradient between forested and grassland ecosystems. However, in recent years, pinyon-juniper woodlands have spread, possibly due to heavy grazing, fire suppression, exotic species introduction or drought, invading both forest and grassland areas. The increase of these unpalatable trees and shrubs has resulted in a decrease of perennial grasses and other forage type plants such as aspen, and has also resulted in increased erosion within the watershed. The Smith Canyon Fuels Project, carried out by dedicated hunters, was conducted to remove encroaching pinyon-juniper to help improve wildlife and grazing habitat. Native grasses were planted after the project. Interested partners are currently working on a monitoring plan to further understand pinyon-juniper ecosystems.
