Earlier in our BTE Blogs we talked about the importance of retaining natural habitat within the urban environment whilst addressing potential risks associated with the failure or structural collapse of dead and/or dangerous trees.
So why is the retention of these types of trees so important? Many species of wildlife utilise tree hollows for nesting, shelters and safe refuges, and recent information suggests that this may exceed 300 individual species.
Some of the more common species that everybody would know, and which form part of our unique wildlife in Australia include Kookaburras, Cockatoos, Galah’s, Possums and Sugar Gliders, and that just scratches the surface! By removing trees that have the potential to provide habitat for these types of animal, we are having a significant impact on the biodiversity of our local environments.
It is generally considered that natural hollows can take between 120 – 150 years to develop in trees, through the process of failure and decay, and this alone highlights the important role that arborist’s can play, by reducing the occurrence of habitat destruction through education and the implementation of modern techniques.
Specialised pruning techniques have now been introduced to Australia which qualified arboristâ€™s can not only apply to dead trees, but can in certain circumstances be introduced into living trees, and with appropriate consultation and application are highly beneficial to a range of native wildlife species.
The use of some nifty chainsaw work by a qualified arborist and the application of coronet cuts or fracture pruning can have real implications in the potential creation of habitat. Not only can these techniques give the tree a natural “storm damaged” appearance, but they can aid in colonization by micro-organisms that assist with hollow development.
