Rodents burrow into soil cover and create erosions at the landfill. Reducing rodent populations helps maintain the integrity of the landfill cover. Therefore, owl boxes and raptor perches were installed at the landfill in 2017 to attract raptors and encourage the natural removal of gophers, ground squirrels and other rodents.
Raptors are a group of predatory birds including hawks, owls, eagles, and falcons. These birds often prey upon rodents and control rodent populations. Raptors alone do not completely eliminate a rodent problem, but attracting raptors as part of a pest management strategy can reduce the cost of conventional control methods and it is also an environmentally-friendly way to reduce rodent populations. In the photo below you can see a raptor using the perch.
