Carter Christina Lund Steven Walterscheid 20190419 publication PLOS ONE vol. 14, issue 4 n/a Public Library of Science (PLoS) ppg. e0214099 https://doi.org/10.1371/journal.pone.0214099 Here we present the map of potential suitable habitat for Ash Meadows gum-plant (Grindelia fraxinipratensis). The data indicate both how many models predicted each location to be potentially suitable for the species and the average standardized habitat suitability score for each location.Data are presented at a spatial resolution of 10 m pixels, which was required to harmonize the original model inputs. However, maps of suitable habitat should be used at a resolution no smaller than 360 m (i.e., 36 pixels x 36 pixels), which corresponds with the resolution of the coarsest model input. These data are intended to be used only to target future plant surveys in areas where new occurrences are most likely to benefit future habitat modelling efforts. Complete methods and other additional information are provided in the article associated with this data release (Reese and others, 2019). These data were developed to provide maps of probable and potential suitable habitat for 43 rare plants in the California desert to inform future planning and management actions undertaken by the Bureau of Land Management and others.

Digital and/or Hardcopy 2014 publication date Additional existing habitat models Existing models used to map probable and potential suitable habitat. We mapped potential suitable habitat for this and all species using existing habitat models as follows. Potential suitable habitat maps: We used models not used to map the outer boundary of probable suitable habitat to map potential suitable habitat (Reese and others, 2019). We modified the existing (input) models to meet the target 80% occurrence capture rate whenever possible. The union of these models became the initial map of potential suitable habitat. The map was then masked to exclude an area of permanent water (the Salton Sea) using the US Geological Survey National Hydrography Dataset.Each final map of potential suitable habitat indicates both how many models predicted each location to be potentially suitable for that species and the average standardized habitat suitability score for each location.
