SHIM (Sensitive Habitat Inventory and Mapping)

As resource development and human populations increase In British Columbia, pressures on all resources and services have accelerated. Rapid growth has often overwhelmed the ability of local planners to manage land and preserve sensitive habitats. This has resulted in loss or degradation of habitats that once supported fisheries and wildlife. Sensitive ecosystems and critical habitats are becoming increasingly threatened.

There is an urgent need for better methods to conserve and protect these habitats. The Sensitive Habitat Inventory and Mapping (SHIM) Atlas represents a response to this need. The SHIM Atlas is a land-planning, interactive GIS tool that identifies sensitive aquatic and terrestrial habitats.   The Atlas is intended to provide community stewardship groups, individuals, regional districts and municipalities with an effective low cost delivery system for information on these local habitats and associated land uses. The awareness and commitment to local resources is an important process created through cooperation of local communities, First Nations, municipalities, planners, and managers. SHIM mapping and data systems developed to date reflect the use and interests of many of these agencies and community groups.

The SHIM Methods & Standards, widely used by local governments in BC since 2002, have been the basis for 1:5,000 fish habitat inventory. SHIM methods were designed to use with a Trimble survey grade GPS to provide stream center line accuracy. But now that mobile devices (with GPS) are everywhere it is time for a SHIM-Mobile version focused on the most frequently mapped point features. Check out the “Atlas Update & News” section below for announcements about this new feature.

The primary functions of the SHIM Atlas are:  

- identify sensitive habitats and resources within local communities;

- integrate property boundaries, and road networks with locations of sensitive resources to facilitate official community plans and development permit applications;  

- work within an interactive Geographical Information System (GIS) to provide useful map products for analysis and effective communication;  

- facilitate updating and exchange of information;  

- establish partnerships with provincial and municipal governments, stakeholders, and the public to protect and manage fish habitat.

By combining resource information from a variety of sources the SHIM Atlas can provide a strong foundation for improving integrated resource management and planning in urban and rural areas. This video shows how SHIM observations are made in the field http://www.youtube.com/watch?v=Xmov6BBm4Gg

Atlas Update & News

A new version of SHIM data forms is coming in Feb. 2018, suitable for use on an iPhone or iPad (iOS device).

This new version is scaled down to capture the stream and fish habitat attributes that are used most often. Each feature or attribute can be located using the GPS receiver built into the iOS device. Note, iPads that do not have cellular data capability do not have a built in GPS but you do not need a data plan to use the new SHIM data forms - field observations and photos can be taken off-line. We will have more information about "SHIM-Mobile" in the coming weeks.
