The habitat for M. jansenii has been extended northwards by 500m thanks to a recent expedition by Keith Sarnadsky, Ray Johnson and Carly Sugars.  This may not sound like much, but for a species as rare as M. jansenii, every bit counts. 

On the 19th October 2020, the intrepid naturalists explored further north into potential Macadamia jansenii habitat.  This is rugged territory, and slow going when identifying plants on the way, but they were rewarded by finding previously unrecorded trees of this rare species. Of particular interest was a small “grove” of M. jansenii, in marked contrast to other known sites where trees are scattered at intervals through the forest.

After the bushfires burnt 25% of the known population, it is a great relief to find new areas that the fires did not reach.

Encouragingly, there was good nut set on some of the trees, although the rapidly drying and heating conditions may mean that not many of the nuts reach maturity.
