Practices and Impacts
- In 2016, the project was initiated with the installation of 20 nesting boxes. Two years later, 10 of the original 20 boxes were relocated to areas within the riparian forest.
- Three additional nesting boxes added in 2021, and six boxes were lowered to provide better access.
- Since 2020, annual monitoring of the nests has taken place including observations of activity, and nesting success have been documented along with other species of wildlife present in the area.
