Sensitive Habitat Inventory Mapping, or SHIM, is an ecosystem-based mapping technique that focuses on the conservation and preservation of aquatic habitats and their riparian areas. SHIM maps watercourses with a Global Positioning System (GPS) unit and marks the location of notable features such as culverts, obstructions, wetlands, vegetation, erosion points, fish sightings, etc.
The benefits of SHIM include:
The SHIM GPS information can also be used to compare the mapped location of creeks against the true location, which is useful for inventory and tracking purposes.
To date the City of Surrey has completed SHIM studies in the following watersheds:
Little Campbell River drainage catchment Hyland Creek drainage catchment Upper Serpentine River drainage catchment (upstream of 168 St) Upper and Lower Bear Creek drainage catchment Patullo drainage catchment Portions of the Clayton drainage catchment (underway)
The data from these studies is available on COSMOS or by contacting Engineering - Drainage and Environment at 604-592-6936
