Species At Risk

CBA Ltd. has experience conducting targeted inventories for a number of Species at Risk in a wide range of taxa including birds, mammals, amphibians, and plants. Other studies involving Species at Risk include habitat assessments and habitat model development. Members of the CBA Ltd. team have written several status reports, management plans and recovery strategies for Species at Risk for both the provincial and federal government.

Status of Peregrine Falcon (2014)

After preparing a status report on the Peregrine Falcon for the BC Government in 2004 and the Canadian Government in 2007, John Cooper is re-assessing the Peregrine Falcon under new CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) criteria for Environment Canada.

Pacific Gophersnake Management Plan (2013)

In 2013, CBA led preparation of a management plan for Pacific Gophersnake populations and habitat on Department of National Defence lands in interior British Columbia. The work included a survey of habitat and preparation of the management plan.

Inventory and Habitat Assessment for Rare Butterflies (2011)

In 2011, CBA inventoried and assessed habitat for the Endangered Dun Skipper, and other rare butterflies, on Department of National Defence lands in the Fraser Valley. The work included field surveys, assessments, and preparation of a technical report.

Species At Risk Development Program for BCTS (2008)

This project focused on the plant and animal Species at Risk (SAR) of the Quesnel and Williams Lake Timber Supply Areas. The program was designed to develop management tools that could be applied during forestry operations to identify and conserve the diversity of species across the managed forest landbase. A manual was developed to aid forestry workers in identification and understanding of Species at Risk.

Canada Warbler Habitat (2007 to 2009)

The main goal of this project was to quantify specific habitat requirements for Canada Warblers in the Fort Nelson Forest District of British Columbia. The collection of field data on habitat variables such as shrub cover, canopy closure, slope, shrub and tree species compostion, CWD cover, and stand age was used to develop a predictive habitat model and to identify high value habitat for Canada Warbler in northeastern British Columbia.

Williamson's Sapsucker Monitoring (2007)

This inventory of Williamson's Sapsucker focused on locating active territories and nests over large geographic areas of south central BC. Data were used by the Williamsoní Sapsucker Recovery Team to develop population estimates for different regions within British Columbia and an overall provincial population estimate. Data on trees used for nesting and foraging were used to better describe forest stand characteristics of breeding areas.

Inventory of Lewis's Woodpecker in the East Kootenay

In 2007, CBA Ltd conducted a complete survey of nesting Lewisís Woodpeckers in the East Kootenay, repeating a study done by us in 1997-1998. The study was designed to obtain population trend data in support of recovery efforts for this Blue-listed species by the Lewisís Woodpecker Recovery Team. Suzanne Beauchesne prepared the updated COSEWIC status report for the Government of Canada in 2009. In 2014, John Cooper is a member of the Lewisís Woodpecker Recovery Team and a recovery strategy is being produced with leadership from Environment Canada.

Flammunlated Owl Management Plan for British Columbia (2005)

A thorough analysis of existing field data and currently available literature on Flamulated Owl occurrences and habitat variables was conducted during the development of this management plan. The plan explores recommended strategies for successful habitat management and recovery of Flammulated Owl populations in BC. In addition to population, habitat and research action plan developments, partial-cutting harvesting methods are discussed relative to such practices ability to maintain elements of Flammulated Owl habitat.

American Bittern and Short-eared Owl Surveys (2003)

American Bittern and Short-eared Owl surveys and habitat assessments were conducted throughout the Columbia Basin in May 2003. Call-playback was used to survey for bitterns in marsh habitat. Visual surveys were used to search for Short-eared Owls in appropriate habitats.

Northern Goshawk (2003 to 2008)

Northern Goshawk surveys were conducted during the breeding season in TFL 37 in the Nimpkish Valley on Vancouver Island. All known historic nests were visited to determine the status of each nesting territory. In addition areas thought to have relatively high potential for nesting Queen Charlotte Goshawks, as predicted by a habitat model developed by CBA Ltd., were also surveyed for activity. Surveys followed Resource Inventory Standards Committee (RISC) Standards for Raptor Surveys, and consisted mainly of call playback and nest search surveys.

Conservation of Engangered Coastal Vesper Sparrow and Streaked Horned Lark (2002 to 2014)

Since 2002, CBA Ltd has been leading field studies to assist with recovery of populations of the Coastal Vesper Sparrow and Streaked Horned Lark in British Columbia. The Coastal Vesper Sparrow is currently confined to one breeding site on Vancouver Island and Streaked Horned Lark appears to be extirpated as a breeding bird in Canada. Projects include inventory, habitat assessment, nest monitoring, capture and banding of birds, development of habitat management guidelines, development of recovery strategies, and development of habitat action plans. All projects are sponsored by the Vertebrate Recovery Implementation Group of the Garry Oak Ecosystem Recovery Team.

Garry Oak Ecosystem Recovery Team, Vertebrate Recovery Implementation Group

Since 2002, Suzanne Beauchesne and John Cooper have been members of this subgroup of GOERT which has a mandate to recover populations of five species of vertebrates. By 2014, Western Bluebird has been re-established as a breeding species on Vancouver Island, the last population of Coastal Vesper Sparrow continues to be monitored and habitat conservation has been undertaken, and plans for work on the other species are considered.

Status Reports for Species At Risk

John Cooper and Suzanne Beauchesne have co-authored numerous provincial and federal status reports on bird species at risk including Spotted Owl (2008), Band-tailed Pigeon (2007), Black-footed Albatross (2006), Peregrine Falcon (2006), Prairie Falcon (2004), Streaked Horned Lark (2003), Queen Charlotte Goshawk (2001), Bay-breasted Warbler (1997), Cape May Warbler (1997), Canada Warbler (1997), Connecticut Warbler (1997), Black-throated Green Warbler (1997), Philadelphia Vireo (1997), Sandhill Crane (1996) and Williamsonís Sapsucker (1995).
