Between 2010 and 2016, PRNS moved forward with a historic vegetation mapping project that involved manual interpretation (“head’s-up digitizing”) and classification of broad, structurally based vegetation communities for black-and-white (B&W) aerial photograph sets obtained from the early 1940’s (40’s) and the early 1960’s (60’s). Mapping was also already available for the late 1990’s (90’s) from an earlier 1994 vegetation map (CDFG/AIS) of PRNS that had been revised to reflect changes following the 1995 Vision Fire as part of a dissertation project (Forrestel et al. 2011). PRNS staff had converted the revised 90’s map to the classification system used for the earlier mapping periods, but these GIS files had never been fully reviewed for accuracy and finalized. In 2022, PRNS received funding from a NPS Functional Conditional Assessment (FCA) grant and from the Point Reyes National Seashore Association (PRNSA) to fund QA/QC and revision of the three (3) historic mapping periods (early 40’s, early 60’s, late 90’s) and to crosswalk and revise the most recent large-scale vegetation map from 2018 (’18) for Point Reyes (Tukman Geospatial Analysts/AIS).
