American Marten Welfare and Old-Growth Forest Loss in Canada

American martens are forest specialists dependent on old-growth and mature boreal forest in Canada for denning and prey. Industrial logging removes the coarse woody debris and structural complexity they require, causing local population collapse.

Key Facts

American martens are classified as Special Concern in Canada due to forest management
They require large fallen logs, stumps, and subnivean spaces for denning and prey capture
Clear-cut logging removes the structural diversity that martens need within 5-10 years of cutting
Recovery of marten habitat after clear-cutting takes 50-80 years
British Columbia and Ontario have significant marten populations but are subject to major logging operations

Welfare Considerations

Martens in clear-cut landscapes cannot find adequate denning sites for winter survival or raising young. Exposure without access to subnivean insulation causes hypothermia risk in winter. Prey availability collapses in structurally simplified logged forests. Local population collapse happens rapidly after logging, with individuals dispersing into unsuitable habitat or dying. The welfare harm is landscape-scale and driven by industrial timber extraction decisions.

What You Can Do

Support Ancient Forest Alliance campaigns protecting old-growth forests in British Columbia
Donate to Canadian wildlife conservation organisations monitoring marten populations
