Logging puts spotted owl at risk
British Columbia's spotted owl population has been dwindling steadily for more than a decade, but recent logging in the Fraser Valley has exacerbated the problem.
The cleared-out forests have drastically reduced the prey and habitat space available to the owls - and many have starved as a result.
Spotted owls breed slowly, producing an average of two chicks each year. Experts estimate that there are about a dozen spotted owls left in British Columbia's forests.
Activists claim the logging is taking place in a designated wildlife habitat and have assembled near the site in protest.
