Critical Information for Qualified Environmental Professionals Undertaking Environmental Assessments in the South Okanagan Similkameen

SOSCP has collated the following list of resources in support of land planning and high quality Environmental Assessments related to Development Permits. Information is sorted by topic:

  • Mapping and Data
  • Legislation, Policy and Best Management Practices
  • References, Unpublished Reports and Other Important Information
  • Community Specific Resources

Critical Habitat for the following species located in the South Okanagan Similkameen is available:

  1. Branched Phacelia
  2. Behr’s Hairstreak
  3. Halfmoon Hairstreak
  4. Great Basin Spadefoot
  5. Grand Coulee Owl-clover
  6. Lewis’s Woodpecker
  7. Williamson’s Sapsucker
  8. Nugget Moss
  9. Pallid Bat
  10. Sage Thrasher
  11. Scarlett Ammannia
  12. Slender Collomia
  13. Desert Nightsnake
  14. Great Basin Gophersnake
  15. Western Rattlesnake
  16. Short-rayed Alkali Aster
  17. Tiger Salamanger
  18. Toothcup
  19. Yellow-breasted Chat
  20. Stoloniferous Pussytoes
  21. Dwarf Wooly-heads, Southern Mountain Population
  22. Rusty Cord-moss

All Critical Habitat is available directly through Canada Open Data Portal, for most of the species on this list is also available through IMAPBC or Data Distribution Service (sees next section) except for snakes (Desert Nightsnake, Great Basin Gophersnake and Western Rattlesnake). Critical Habitat for snakes requires a data sharing/confidentiality agreement with Environment and Climate Change Canada (ECC). Interim contact with ECC is Darcy Henderson 1238 Discovery Avenue, Kelowna, British Columbia, V1V 1V9 / Tel. 250-491-1507 / Cell: 306-502-4628

How do I access Critical Habitat Maps and Spatial Data? 

Critical habitat data for terrestrial species at risk can be accessed in a number of ways.

 BC Tools: iMap & Data Distribution Service:

Critical Habitat identified for terrestrial species under the federal Species at Risk Act within British Columbia is available to the public via the BC Geographic Warehouse. This data includes both “Final” and “Proposed” critical habitat, as depicted in recovery documents that have been posted on the Species at Risk Public Registry by Environment and Climate Change Canada or Parks Canada. **Note that the federal government is the custodian of this data, and that critical habitat identified for aquatic species within BC is not currently available through BC Tools.

Access this critical habitat data using either of these three tools:

A. iMapBC 2.0

Look in the layer library under “Fish, Wildlife and Plant Species” Group. Choose the layer “Critical Habitat for Federally-Listed Species at Risk – Posted”. Note that critical habitat polygons will only be shown when zoomed to a scale of 1:800,000 or larger.

B. Data Distribution Service: Download or connect to the data

C. Environment and Climate Change Canada has made the geospatial files for “Final” and “Proposed” critical habitat  available as “Open Data” for the public. Note! This data is the same critical habitat data that is available through the BC Geographic Warehouse (e.g., iMap). Click here for EC Datamart

How do I Access Sensitive/Masked Critical Habitat Data? 

Environment and Climate Change Canada must oversee the distribution and confidentiality of sensitive data.

Policy Advice Regarding Interpretation of Occurrence and Attribute-based Critical Habitat

The following is referenced in the Regional District Okanagan Similkameen (RDOS) Development Procedures Bylaw (found here go to pg 28), and is provided in support of quality Environmental Assessments throughout the Okanagan.

Occurrence-based Critical Habitat: Critical Habitat for the species listed below are based on known, recent occurrences (or occupied habitat). As directed in the development procedures bylaw, Critical Habitat for them would be considered ESA-1.

  • Sage Thrasher (Oreoscoptes montanus)
  • Branched Phacelia (Phacelia ramosissima)
  • Scarlet Ammannia (Ammannia robusta)
  • Toothcup (Rotala romosior)
  • Grand Coulee Owl-clover (Orthocarpus barbatus)
  • Short-rayed Alkali Aster (Symphyotrichum frondosum)
  • Yellow Breasted Chat (Icteria virens aurocollis)

Attribute-based Critical Habitat: Critical Habitat for the species listed below are based on habitat attributes. As directed in the development procedures bylaw, Critical Habitat for these species would be considered ESA-2. In circumstances where Critical Habitat includes known, recent occurrence(s) (or occupied habitat), the QEP should consider if an ESA-1 rating is required to protect habitat and prevent destruction of Critical Habitat, consistent with requirements in the federal Species at Risk Act (SARA). Other considerations may also result in an ESA-1 designation within areas of Critical Habitat for the species listed below. For example, where Critical Habitat areas also contain locally or provincially significant ecosystems, uncommon and other important to rare wildlife species.

  • Half Moon Hairstreak (Satyrium semiluna)
  • Lewis’s Woodpecker (Melanerpes lewis)
  • Behr’s Hairstreak (Satyrium behrii)
  • Williamson’s Sapsucker (Sphyrapicus thyroideus)
  • Spadefoot Toad (Spea intermontana)

The vision of SOSCP is to maintain a healthy environment that sustains the diversity of indigenous plants and animals while enriching people’s lives. The six broad strategic objectives that guide SOSCP activities are:

SOSCP recognizes that decisions, policies and practices are important to ecological conservation and works to provide the tools and guidance needed to make sustainable planning choices.

Sustainable Land Use Planning

Supporting the acquisition of key habitats includes purchases, covenants or donations of private land, often in conjunction with enhanced protection of Crown lands. Securement activities include restoration, care, and management of these important areas.

Securing Key Habitats

SOSCP promotes stewardship activities and encourages landowners to protect biodiversity, enhance habitat for plants and wildlife, and manage lands sustainably.

Enhancing Stewardship on Public and Private Land

Involving communities in conservation is essential. SOSCP support professional development workshops, school programs, festivals and outdoor seminars that foster a love and understanding of our natural environment.

Expanding Community Involvement

SOSCP is committed to using a science-based approach to guide actions and decision-making, and to promote and facilitate further scientific research for species and ecosystems at risk.

Applying a Science-Based Approach

The En'owkin Centre continues its work to recover, revitalize and perpetuate Syilx Traditional Ecological Knowledge (TEK) so it can be applied throughout traditional Syilx territory.
