Layer: USNVC 1.0 (2013-2020) (ID: 5)

Name: USNVC 1.0 (2013-2020)

Display Field: ALLIANCECOMMONNAME

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This dataset contains vegetation mapping completed between 2013 and 2019, using the USNVC 1.0 hierarchy; in spring 2020 OSMP began converting the data to the new USNVC 2.0 hierarchy. This new dataset is called "VegetationUSNVC" . The VegetationUSNVC feature class will be updated with all ongoing field mapping efforts.</SPAN></P><P><SPAN>The US National Vegetation Classification (USNVC) data is a heirarchical format that is a central organizing framework for documentation, inventory, monitoring of OSMP vegetation. The upper levels of the USNVC hierarchy (including Subclass) are based on dominant and diagnostic growth forms that reflect environment at global to continental scales. The mid-levels are based on dominant and diagnostic growth forms and compositional similarity reflecting biogeography and continental to regional environmental factors; these were introduced in . The lower levels (Alliance and Association) are based on diagnostic and/or dominant species and compositional similarity reflecting local to regional environmental factors. The Association is the level at which rare and senstive plant communities tracked by the Colorado Natrural Heritage Program are identified and mapped. Thus, the current target level for mapping on OSMP is the Association. While most of the Alliances and Associations are recognized by USNVC, some are provisional types that have been created by OSMP to represent unique vegetation types. </SPAN></P><P><SPAN>OSMP has also developed Conservation Targets (ConsTargets) as part of the development of the Grassland Ecosystem Management and the West Trail Study Area planning efforts but as a way to further categorize biological diversity. Systems, species and community services have been identified as repesentatives of the relevant natural resource and agriultural community services and enable the tracking of OSMP's viability status and trends. These ConsTargets are not a part of the USNVC heirarchy and are internal to OSMP. Descriptions of these Conservation Targets can be found in OSMP's Grassland Ecosystem Plan (https://www-static.bouldercolorado.gov/docs/final-grassland-plan-1-201910251412.pdf) and Trail Study Area Natural Resources Inventory Report (https://www-static.bouldercolorado.gov/docs/wtsa-nr-inventory-report-1-201307151526.pdf?_ga=1.222847003.1823101693.1446591237).</SPAN></P></DIV></DIV></DIV>
