Creating Wildlife Habitat Trees
This class will discuss and demonstrate how instead of removing trees to the ground, portions can be safely retained and used as habitat. Demonstration will include techniques like ‘Coronet Pruning’ and how you can create bird boxes by either using pre‐existing cavities or creating them with the use of a saw. You will learn how you can attract the type of animal you are creating habitat for by the size and location of the holes you create, such as making large angled upward cuts into the side of a standing log creates a great space for bats to roost.
As arborists it is our job to evaluate trees and give solutions to mitigate risks. Oftentimes wildlife habitat exists in tree risks in the form of cavities, dead snags or broken tops. We could say that our job as an arborist is to identify wildlife habitat, then prune or remove it. We should recognize that wildlife need homes. The presence of wildlife in trees is often associated with risks. However, in many cases risks can be reduced and mitigated while retaining existing wildlife habitat or creating new wildlife habitat. Not all trees need to be used as habitat trees, but in the right place it can make a large difference to the community around. Furthermore, in some instances, removing habitat may be breaking the law. Often climbing arborists are making first ascents into the crowns of trees and may come in contact with wildlife. Knowing regulatory laws and protected species is the arborist’s responsibility. It’s up to the people that are taking care of trees to realize the value in preserving and creating habitats, so we can live more symbiotically in the world.
