Princeton Sei Presentation August 19 [Compatibility Mode] Princeton Sei Presentation August 19 [Compatibility Mode] Presentation Transcript

  • Sensitive Ecosystem Inventory (SEI) Regional District of Okanagan Similkameen August 19, 2009 Maureen V. Ketcheson R.P.Bio. Ecology Manager, Victoria Branch Dave Caswell R.P.Bio Project Manager, Kamloops Branch 1
  • Outline Introduction Project Objectives Background - Sensitive Ecosystem Inventory SEI Mapping Process Results 2
  • Dave Caswell, RPBio Maureen V. Ketcheson, Ecology Mgr, Kamloops RPBio – Ecology Mgr, Branch. Victoria Born and raised in Merritt Born and raised in Regina, Sheldon Williams Collegiate Educated at University College of the Cariboo Educated at U of R, U of Vic, and Lakehead U B.Sc Biology (wildlife) 1995 B.Sc Biology (botany) M.Sc. Wildlife consultant since 1995 Quantitative Ecology Wildlife generalist (songbirds, BC Ministry of Forest Regional mule deer) Ecologist, Nelson BC 1981-84 Joined Timberline in Dec, 2007 – Consultant in eco mapping since Ecology Department Manager 1984 Ecology Manager for Timberline Victoria since 2005 Specializing in TEM (terrestrial ecosystem mapping) and PEM (predictive ecosystem mapping) in BC Certified trainer in TEM and a “senior” PEM practitioner 3
  • Project Objectives To provide baseline mapping information to support land use planning for parts of Electoral Area H The mapping will identify ecosystems which are: sensitive / rare / fragile. Identify the plant and wildlife Species at Risk associated with these ecosystems. Support management / best practices recommendations for these ecosystems and their associated SAR. 4
  • Background Sensitive Ecosystems Inventory (SEI) Provides spatial and data base information to land managers Forms a backdrop to assist in the conservation and protection of sensitive and important ecosystems 5
  • Planning Tools Rare ecosystem Heli ski proposal 2 Class 1 grizzly Spring range Sensitive ecosystem complex Heli-ski proposal 1 6
  • Planning Tools 7
  • Sensitive Ecosystems – Biologically Diverse Grasslands conservation council www.env.gov.bc.ca/sei/images/ri.jpg Sensitive Ecosystems are defined as; “Those remaining natural terrestrial ecosystems which are considered fragile or rare in the SEI study area: wetlands, riparian, old forest, grassland, broadleaf woodland, coniferous woodlands, sagebrush steppe, antelope brush steppe, alpine and sparsely vegetated ecosystems” (Environment Canada 2008) 8
  • Sensitive Ecosystems – Biologically Diverse 9
  • Sensitive Ecosystems – Community Identity 10
  • Princeton SEI Project Area Location and Existing SEI Mapping in the Okanagan 11
  • Bio-Geo-Climatic Ecosystem Classification system (BEC) : BEC divides the landscape into areas of uniform “meso- climates” which have similar potential to support the same spatial combinations of ecosystems in similar combinations of terrain and site. 12
  • Biogeoclimatic Ecosystem Classification Overview 13
  • The SEI Mapping Process A working map legend of the potential Sensitive Ecosystems Air photo and ortho-photo images are obtained and study area boundaries applied BEC boundaries delineated SEI polygons delineated Red and blue listed site series polygons delineated 14
  • The SEI Mapping Process Each polygon is described in a standard data base Field sampling plan is prepared to visit a percentage of polygons to verify and correct photo interpretation Mapping is updated Final reports and data bases 15
  • Step one: Working Legend SEI Code SEI Class Description Ecosystems dominated by Trembling aspen occurring in depressions and moist BW Broadleaved woodlands areas FS Seasonally flooded fields GR Grasslands A mix of seral and climax tree species generally greater than 80 years old MF Mature forests Climax trees generally greater than 140 years old OF Old forests Treed or shrubby ecosystems associated with pond and lake shorelines, swamps, RI Riparian floodplains or gullies with intermittent or permanent creeks Ecosystems with little vegetation occurring on bedrock or colluvial features SV Sparsely vegetated Open stands of Douglas-fir or Ponderosa pine, often on shallow soils with grassy WD Coniferous woodlands understories, old woodlands are part of the Old Forest category Ecosystems where the water table is at or near the surface. WN Wetlands 16
  • Step two: study area and BEC boundaries 17
  • Step three: delineate SEI, red and blue-listed ecosystems 18
  • Rare ecosystems have been identified by the Conservation Data Center Red-listed ecosystems are defined as the ecological communities considered provincially rare, regardless of present day seral status Blue-listed plant communities considered provincially vulnerable, focus is often on mature and old seral stages 19
  • Rare and Endangered Species COSEWIC – The Committee on the Status of Endangered Wildlife in Canada Endangered, Threatened, Special Concern BC Conservation Data Center: Ecosystem Explorer Website: http://a100.gov.bc.ca/pub/eswp 20
  • Chain Lakes example SEI polygons 21
  • Step four: Field Sampling 22
  • Step five: Update Maps Update maps with information collected in the field. 23
  • Results - Sensitive Ecosystems in the Chain Lakes Study Area 21% of the total study area composed of sensitive ecosystems. Grasshopper Yellow-bellied racer Grasslands Sparrow (Red) (SC,Red) 24
  • Results - Sensitive Ecosystems in the Chain Lakes Study Area Seasonally Flooded Fields Great-basin Spadefoot (T,Blue) 25
  • Results - Sensitive Ecosystems in the Chain Lakes Study Area Painted Turtle (SC) American Wetland Avocet (Red) 26
  • Otter Lake 27
  • Results - Sensitive Ecosystems in the Otter Lake Study Area 28% of the total study area composed of sensitive ecosystems. Riparian ff Olive-sided Flycatcher (T,Blue) 28

  • Results - Sensitive Ecosystems in the Otter Lake Study Area Coniferous Woodlands Northern Alligator Lizard 30
  • Results - Sensitive Ecosystems in the Otter Lake Study Area Mature Forest Flammulated Owl (SC, Blue) 31
  • East Gate 32
  • Results - Sensitive Ecosystems in the East Gate Study Area 31% of the total study area composed of sensitive ecosystems. Coniferous Woodlands Lewis’s Woodpecker Gopher Snake (T, Blue) (SC,Red) 33
  • Results - Sensitive Ecosystems in the East Gate Study Area Steep Grasslands Badger (E,Red) 34
  • Results - Sensitive Ecosystems in the East Gate Study Area Riparian River Townsend's Big-eared Bat (Blue) 35
  • Results - Sensitive Ecosystems in the East Gate Study Area Riparian Floodplain Western Screech-Owl (E,Red) 36
  • Results - Sensitive Ecosystems in the East Gate Study Area Townsend's Big-eared Rubber Boa (SC) Bat (Blue) Sparsely Vegetated Rock 37
  • What about the Plants? a. c. PRIZES!!! b. 38
  • What about the Bugs? MORE PRIZES!!! c. a. b. 39
  • Questions? 40
  • SEI Map Label Interpretation Each polygon can have up to three SEI subclasses or up to three red or blue listed site series described in the data base The proportional distribution of each is described by a number between 1 and 10 as a “decile” distribution of that ecosystem 41
  • Map Label example 6 RI:ff 4 WN:wm = 60% Riparian : fluvial fringe 40% Wetlands : wet meadow 10 BW:ac = 100% Broadleaved woodlands : Aspen copse 42
