About Sensitive Ecosystem Inventory (SEI)

A Sensitive Ecosystem Inventory (SEI) was conducted for the Metro Vancouver region and Abbotsford from 2010-2012, using 2009 imagery. An update to that inventory was conducted for the Metro Vancouver region only from 2015-2018, using 2014 imagery. The SEI identifies and maps ecologically significant and relatively unmodified Sensitive Ecosystems (SE), including wetlands, older forests and woodlands using provincial standards. The SEI also includes Modified Ecosystems (ME) such as old fields and young forests, which are human-modified but still have ecological value and importance to biodiversity. Ecosystem quality was assessed through an evaluation of condition, landscape context and size. This is a regional-scale inventory of higher quality natural or semi-natural ecosystems and therefore small (less than 0.5 ha for SEs) or very disturbed ecosystems were not included.

For more information please refer to:

Please be aware that the Sensitive Ecosystem Inventory (SEI) was generated remotely using aerial photography and only a proportion of ecosystems were confirmed in the field. It represents a snapshot in time. It may not accurately reflect current conditions due to misclassification or changes in the landscape and does not replace the need for on-site assessment.
