There’s been a lot of talk about major infrastructure projects in Canada lately, with the federal government planning to fast-track resource development across the country. …Yet these economic benefits result in trade-offs for the environment… Examples of unintended environmental consequences aren’t hard to find across Canada. If someone told you about a high-density network of corridors, often spaced less than 100 metres apart, you might picture city roads or an urban park trail system. In fact, such a network of linear clearings, also called seismic lines, can be found across Canada’s boreal forest. There are an estimated over 1.8 million kilometres of such clearings in Alberta alone. …Seismic lines fragment forests and alter their ability to act as habitats and provide climate change mitigation benefits. Forest fragmentation shifts how animals use the region, and has been linked to sharp declines in woodland caribou.
