Interpretive Summary: Juniper management is constrained by limited tools to estimate juniper cover and potential cover at stand closure across landscapes. We evaluated if remotely sensed imagery (NAIP) could be used to estimate juniper cover and if environmental characteristic could be used to determine potential juniper cover at stand closure. We determined that reasonably accurate estimates of western juniper cover can be obtained from NAIP imagery. We also found that environmental characteristics could explain 40% of the variability in juniper cover at stand closure.
