Many people visit Kouchibouguac National Park hoping to see wildlife. Sometimes they are lucky but frequently they leave without witnessing the animals they were looking for.
Park biologists face the same problem when attempting to monitor wildlife populations: it is hard to count animals when you don’t see them.
One technique used to overcome this problem is ‘camera trapping’. This is where specially-designed digital cameras are placed at strategic locations in the park, and cameras automatically take pictures of animals as they pass.
These cameras are usually attached to trees along a trail and when an animal walks by it triggers an infrared motion detector, which in turn triggers the camera shutter.
