Adel Pheloung Most Northern Rivers locals were devastated to watch the decimation of native wildlife during the Black Summer bushfires late last year. A local organisation, Brunswick Valley Landcare (BVL), felt the same, and have begun the fight for rebuilding habitat through the installation of nesting boxes, made by Mullumbimby local, David Brook from Wildbnb. 303 different species of native Australian animals rely on tree hollows for nesting, which, even prior to the Black Summer fires were a rarity, as they take a minimum of 75 years to form, and the bushfires of last summer destroyed a huge percentage of the remaining critical habitat that had already been decimated by land clearing.
