Sensitive Ecosystems Inventory (SEI) Project Boundaries

Sensitive Ecosystems Inventory (SEI) Project Boundaries (STE_SEI_PROJECT_BOUNDARIES_SVW) contain boundaries (study areas) and attributes describing each SEI project (project level metadata), and includes links to the locations of other data associated with the project (e.g. reports, polygon datasets, plot files). This layer is derived from the [STE_TEI_PROJECT_BOUNDARIES_SP](https://catalogue.data.gov.bc.ca/dataset/1313fac7-2ea1-4c6b-995b-bd421b7ec3c6) layer by filtering on the PROJECT_TYPE attribute. Project types include: SEI, TEMSEI, TEMSET, SEIWHR and NEMSEI. SEI project boundaries should be used in conjunction with SEI detailed inventory polygons which identify and map rare and fragile terrestrial ecosystems in a given area for the purpose of encouraging land-use decisions that will ensure the continued integrity of these ecosystems. SEI inventory polygons with full Resources Information Standards Committee (RISC) attributes can be accessed through the [Terrestrial Ecosystem Information (TEI) Data Distribution Packages](https://catalogue.data.gov.bc.ca/dataset/8fd15e4e-e7b1-4566-81d1-1ff8947bfd46). SEI inventory polygons with simplified and amalgamated (concatenated) RISC attributes can be accessed through the [Sensitive Ecosystems Inventory (SEI) Detailed Polygons with Short Attribute Table Spatial View](https://catalogue.data.gov.bc.ca/dataset/b00fd09f-ebe1-4b52-9717-6ef9c243d52e). **Current version**: v12 (2026-06-22)
