Although
much of the landscape of the Thompson and Okanagan valleys likely supported
viable populations of badgers in the past, several human activities have
probably negatively affected badger populations. First, badgers utilize
grassland habitats, which are one of the most rare and threatened landscapes in
the province. Loss of grassland habitats may be the major contributing factor to
the current conservation concern facing badgers (Rahme et al. 1995). Urban
encroachment into grasslands, fire suppression, and increased intensity of
agriculture in grasslands may have also shifted the ecology of these habitats
away from the setting in which badgers have evolved and probably need to
survive. Second, badgers and their prey have long been considered pest species
by farmers and ranchers and were systematically exterminated by hunting,
trapping, and poisoning since European settlers first occupied grasslands.
Third, collisions with vehicles on roadways may be a substantial source of
mortality within badger populations.
Effective
conservation efforts had been difficult to develop because very limited
information was available about the ecology of this species in British Columbia,
even though a conservation need had been clearly identified (Rahme et al. 1995).
A study on badger ecology conducted in the East Kootenay region (Newhouse and
Kinley 2000b), in a limited grassland setting, produced concerning results that
suggested that more information specific to British Columbia was needed to
develop appropriate management recommendations. The goal of our program was to
effectively deal with each of these issues and provide practical solutions to
ensure the persistence of badger populations in the Thompson and Okanagan
regions of British Columbia.
Project Objectives
The specific objectives of our program were the following:
 |
Collect and compile existing information on the distribution and occurrences
of badgers in the Thompson, Nicola, and Okanagan areas. Develop distribution
maps based on known occurrence data and a regional species account,
|
 |
Create public awareness regarding the status and issues surrounding badgers
and other grassland species in the Southern Interior Region through
education programs, |
 |
Identify habitats required by badgers by examining habitat selectivity at a
variety of spatial scales, |
 |
Create habitat management guidelines for habitats that are critical or
important to badgers, |
 |
Develop realistic management guidelines for ranchers and farmers so that
they can reduce their effects on badger populations without substantial
decreases in the productivity of their operations,
|
 |
Identify population factors, land use issues, habitat suitability issues,
and prey base issues that may affect the conservation of badgers in the
region, |
 |
Develop a translocation policy for “problem” badgers, so that these
individuals are not removed from dwindling populations, and
|
 |
Create conservation strategies based on scientific data for the species.
