B.C. Wildlife Battles Extreme Weather

B.C.'s coast is experiencing prolonged atmospheric rivers, posing significant risks to its wildlife. These events, unusual for this time of year, bring heavy rain, increasing the chances of flooding, landslides, and avalanches.

Aquatic ecosystems are particularly vulnerable. Rising water levels mobilize sediment, which can clog fish gills and scour riverbeds, destroying incubating eggs. Past events have also revealed contaminants from overwhelmed water treatment and agricultural areas.

On land, flooding can displace or kill small underground animals. Larger wildlife, like black bears, may be forced from dens prematurely due to saturated landscapes, seeking food sources closer to human areas and increasing conflict.

Natural disasters such as landslides and avalanches pose direct threats to animals and their habitats. Studies indicate that areas affected by wildfires or logging are more prone to these events during atmospheric rivers.

Despite these impacts, atmospheric rivers are also a crucial water source, helping to mitigate drought and reduce wildfire risk. The province is working with partners to address habitat impacts, considering climate change in wildlife stewardship.
