| Summary | As the Bathurst caribou herd has declined in number, portions of their late-summer range have “greened”. This greening is seen in satellite images, which show plants are growing more than they used to. We wanted to find out if this greening is changing the balance of food available for caribou. In the tundra, low-growing vegetation like lichen and grasses are important caribou food. Based on research from other parts of the Arctic, shrubs like birch often become more common as areas green and outcompete smaller plants like lichen, which can reduce the amount of good food for caribou. |
| Local Relevance | This research helps us understand how greening may affect the food available to caribou on the Northwest Territories tundra. |
