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.

Stand density and climate data in the Taylor Woods study area (Fort Valley Experimental Forest) on the Colorado Plateau in Northern Arizona, 1961-2011

These data were compiled for research pertaining to the effects of stand density on growth rates in semi-arid forests. Increasing heat and aridity in coming decades is expected to negatively impact tree growth and threaten forest sustainability in dry areas. Maintaining low stand density has the potential to mitigate the negative effects of increasingly severe droughts by minimizing competitive intensity. By inspecting growth rates and the climate and soil moisture conditions that drive these growth rates we can understand better the positive effects of reducing stand density and the specific dynamics that are beneficial to growth.
