Vegetation indicators and landscape characteristics for the Gearhart Mountain Wilderness, Oregon, USA

This dataset contains spatially-referenced tabular data associated with a study to characterize vegetation conditions within a dry mixed conifer forest study area (the Gearhart Mountain Wilderness) in southern Oregon, USA, in 2001 (a single year drought without any widespread insect mortality) and 2009 (during a multi-year drought that coincided with a severe outbreak of mountain pine beetle; MPB). Specifically, this study identified refugia from the effects of droughts (in 2001 and in 2009) and interacting drought-MPB effects (in 2009). In this study, refugia were defined as local areas that were relatively buffered against detrimental ecological effects from drought and MPB-attack. Refugia were quantified using remotely-sensed Normalized Difference Moisture Index (NDMI) from the Landsat archive across a 30-m resolution grid. This dataset contains the identified refugia in each year (2001 and 2009) along with landscape characteristics (topographic, soil, and forest stand characteristics) that were used as explanatory variables to model the locations of refugia.
