Peninsula Open Space Trust Mid-Peninsula Open Space District Aerial Information Systems 20140326 vector digital data http://bios.dfg.ca.gov/ ftp://ftp.dfg.ca.gov/BDB/GIS/BIOS/Public_Datasets/900_999/ds997.zip Aerial Information Systems (AIS) was contracted by the Midpeninsula Regional Open Space District (MROSD) and the Peninsula Open Space Trust (POST) to create a vegetation inventory of their properties and surrounding areas. Several mapping efforts were completed between 2000 and 2007: Sierra Azul and environs, 2000; Las Pulgas Preserve, 2003; Purisima Creek and environs 2005; Teague Hill and Thornewood preserves, 2006; POST's S. San Mateo map, 2007; La Honda Creek and environs, 2001; and an area that encompasses a number of preserves near Skyline Rd., 2003. The maps were seamed together and dissolved on the veg. type by the MROSD. Some of the individual maps were also sent to CDFW--but at least one of these (La Honda) looks like an older version of the map used in the seamed version. For this reason, the density (cover class) attribute was added to the seamed version by using spatial joins to the individual maps. This means that the polgyons that were split on density, not veg type do not have a density value, To provide a vegetation inventory to the Peninsula Open Space Trust and Midpeninsula Regional Open Space District. This inventory can be used to identify desirable habitats, mappable stands of non-native types, and can serve as a baseline to monitor change over time. https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=78495 https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=78492 https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=78489 https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=78487 https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=78484 https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=78485 https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=78530 Complete None planned -122.447214 -121.824271 37.503651 37.064981 None vegetation Roget's Vegetation Oregon Geospatial Enterprise Office United States of America North America GNIS Santa Clara County Santa Cruz County San Mateo County California USDA Ecoregions Santa Cruz Mountains California Central Coast Leeward Hills Oregon Geospatial Enterprise Office Biosphere None None Midpeninsula Regional Open Space District (MROSD) Casey Hiatt GIS administrator Aerial Information Systems, Inc. produced these datasets for Midpeninsula Regional Open Space District (MROSD) and the Peninsula Open Space Trust (POST) Microsoft Windows 7 Version 6.1 (Build 7601) Service Pack 1; Esri ArcGIS 10.4.0.5524 0 None Base imagery used to map S.

NVCSNAME The standardized name of the vegetation description used in the National Vegetation Classification System (see http://biology.usgs.gov/npsveg/nvcs.html). Since the NVCS does not have categories for human land use or otherwise unvegetated land, those descriptions were drawn from the California Wildlife Habitat Relationship. http://biology.usgs.gov/npsveg/nvcs.html NVCSLEVEL The standardized level of the vegetation description used in the National Vegetation Classification System http://biology.usgs.gov/npsveg/nvcs.html MAPCLASS The finest level of vegetation type (or land use) mapped (alliance, association, group or macrogroup); or land use for polygons that are not natural vegetation, per the mapping classification. map classification varied slightly between projects, see supplemental information PI code used by photo interpreters to represent the mapping class. These codes are defined in the accompanying reports. The MapClass field reflects the definition of this code, except for those that were generally coded as 9000, and have an accompanying LandUse code that defines what land use or unvegetated class best describes. Some polygons will also have a vegetated type defined in this field, with a Land Use that occupies part of the stand described in the Land Use field. Density classes of vegetative cover 1 > 60% 2 40-60% 3 25-40% 4 10-25% 5 2-10% 9 not applicable LANDUSE Where the PI type is identified generally as 9000, meaning unvegetated or urban, this field further defines class for some projects 9100 Government Related Facilities 9200 Agriculture 9201 Abandoned Orchards 9202 Orchard 9210 Rangeland – Pastureland 9220 Olive Groves 9230 Christmas Tree Farm 9240 Plantation Pines 9300 Built-up / Urban Disturbance 9302 Quarry 9400 Sparsely Vegetated or Unvegetated Areas 9410 Landslides, Cliffs, Rock Outcrops 9420 Landslides, Cliffs, Rock Outcrops 9500 Vegetation Restoration Sites 9800 Water 9810 Reservoirs 9820 Small Ephemeral Ponds AIS_ID Identifier used by Aerial Information Systems during the project FIELDCK for Purisima: In-house value for field check and QC status COMMENT Typically notes that clarify typing, or present problems in identification UID Unique identifier for each polygon VegCAMP CALVEGNAME A crosswalk to the CalVeg vegetation system.
