Threats

What are the Threats to the Banff Springs Snail?

A number of threats have been identified for the Banff Springs Snail and its habitat. Details can be found in both the COSEWIC status report and Recovery Strategy and Action Plan available at http://www.sararegistry.gc.ca.

From the most to least serious the threats are:

– water flow stoppages
– flow reductions and fluctuations (natural and human-caused)
– thermal water flow redirections (natural and human-caused)
– limited or low quality habitat
– humans soaking and swimming
– population lows and genetic inbreeding
– human-caused habitat trampling and local disturbance
– human limb-dipping (touching the water with hands or feet)
– stochastic events (such as storms)
– others (such as predation, competition, collecting, and twitch-ups)

Of these 10 categories of threats, humans are involved in six, or seven, if one considers water flow stoppages due to climate change being caused by humans.
