The vegetation mapping efforts, initiated in 1995 after the Vision Fire, passed a major milestone with the delivery of a draft digital vegetation map in the mid-2000s. Aerial photographer interpreters delineated over 12,000 land-cover polygons within the 155,000-acre mapping area that includes Point Reyes National Seashore, Golden Gate National Recreation Area, Tomales Bay State Park, Samuel P. Taylor State Park, and Mount Tamalpais State Park.
In addition to the map, a draft botanical classification following the California Native Plant Society’s and national standards was developed for the region. A statistically rigorous accuracy assessment is currently being conducted to evaluate how well the photo interpreters labeled the 79 land-cover types delineated in the draft map. The completed vegetation map will be a valuable tool to plan and implement the park’s fire management and research programs and compare pre-fire conditions with current conditions.
Science Behind the Scenery: Vegetation Mapping
In 2004, the Pacific Coast Science and Learning Center produced a series of ten Science Behind the Scenery videos to highlight how science is used to learn more about ecosystems, plants, animals, and other organisms at Point Reyes National Seashore and how science is used to guide management decisions. One of the videos focused on vegetation mapping.
