Redwood National and State Parks Vegetation Classification and Mapping Project Completed ! More than Just a Color-coded Type Map!
December, 2013 - The Redwood National and State Parks Vegetation Classification and Mapping Project was completed by Geographic Resource Solutions (GRS) in late June, 2013. Multiple map data sets representing both raster pixel classification efforts and aggregated stand level mapping efforts were developed under the guidelines of the NPS National Vegetation Mapping Program. These data sets represent a new level of detailed, quantitative, species-specific information in addition to the standard National Vegetation Classification System (NVCS) type designation(s). GRS's use of the Discrete Classification methodology also enabled the development of individual species-specific cover component estimates by size class, canopy layer, the "bird's-eye view, and in total; as well as estimates of quadratic mean diameter and stems per acre.
An article excerpted from the Fall/Winter 2013 Kaleidoscope Newsletter of the NPS-Klamath Network that describes more about this project may be accessed at this link.
The following map shows some of the many detailed quantitative stand (polygon) attributes developed in the RNSP Discrete Classification map data set. While the map can be displayed using the color-coded NVCS Association names the data set represents a far greater level of attribution and detail which can be used to generate many, many different types of maps.
The following maps represent the cover distribution (magnitude and extent) of several major species found in the Project Area (SeqSem=Redwood, PseMen = Douglas-fir, AlnRub = Red Alder, and LitDen = Tanoak):
