Summary

The features in this dataset represent the current range for Bombus occidentalis (Western Bumble Bee). The current range is defined as the maximum current geographic extent of B. occidentalis based on current occurrence records (date range: 2002-2022) from the Bumble Bees of North America Occurrence Record Database (Richardson 2023), California Natural Diversity Database (CNDDB), and other datasets submitted directly to California Department of Fish and Wildlife (CDFW). This dataset was created May 2023.

Description

Range polygons may include areas not currently occupied by a species and, conversely, may omit areas potentially used by a species. The boundary delineations are primarily based on ecoregion subsections (USDA F.S., Ecomap Subsections 2007) and 10 Kilometer occurrence buffers.

Criteria used to delineate range boundaries:

  1. Select all occupied ecoregion subsections.

  2. If subsection is composed of two separate polygons, select only the subsection polygon containing occurrence/s.

  3. Buffer species occurrences by 10 Kilometers (per maximum buffer distance suggested by scientific literature.

  4. If occurrence buffer extends outside a selected subsection, expand subsection boundary to incorporate buffer.

  5. If non-selected subsection is surrounded by selected subsections, incorporate non-selected subsections into species range after assessing vegetational characteristics.

  6. Clip species range by California State boundary.

  7. Merge ecoregion subsections to create seamless species range polygons.

EcomapsubSections_2007 - Metadata

The Ecomap Subsections feature class contains ecological subsection polygons attributed with subsection names and descriptions. The EcomapSubsections 2007 data set describes the ecological subsections within the conterminous United States. It contains regional geographic delineations for analysis of ecological relationships across ecological units. ECOMAP is the term used for a USDA Forest Service initiative to map ecological units and encourage their use in ecosystem-based approaches to forest land conservation and management. This is a collaborative effort with many partners. It is coordinated at the national and regional levels by USDA Forest Service staff and implemented in cooperation with State forestry agencies and others. ECOMAP mapping criteria are outlined in the National Hierarchical Framework of Ecological Units ( https://www.fs.usda.gov/Internet/FSE_DOCUMENTS/stelprdb5286434.pdf ). The framework systematically divides the country into progressively smaller areas of land and water that have similar physical and biological characteristics and ecological processes.

Note: The "EcomapSubSections_2007" was downloaded from the USDA Forest Service Clearing House website on January 17, 2023.
