BIOCLIM generates climate estimates based on meteorological data and topographical information (Busby 1991). User input of the distribution of taxa is used to create climatic profiles, which can subsequently allow predictions of further distributions of these taxa (Busby 1991). BIOCLIM requires precipitation and temperature information, but does not take substrate into account. Leptospermum namadgiensis has only been found on a limited number of substrates, namely porphyritic and muscovitic leucogranite (Yaouk Peak), undifferentiated leucogranite (Scabby Range) and granodiorite (The Sentry Box and Mt Namadgi). As L. namadgiensis has not been found on nearby peaks of similar climate and altitude (Mt Morgan-as predicted by BIOCLIM), it appears that L. namadgiensis may be restricted to certain substrates. Further experimentation would be needed to properly test this hypothesis.

and Olearia rhizomatica Lander ms X
Olearia rhizomatica is found on the same substrates as Leptospermum namadgiensis but in addition it is found on Mt Morgan (adamellite and granodiorite). Olearia rhizomatica appears not to be as restricted by substrate as L. namadgiensis.
Olearia rhizomatica has been recorded from Namadgi and Kosciuszko National Parks, and Scabby Range Nature Reserve. Olearia rhizomatica is listed by Briggs & Leigh (1996) and has been given a conservation code of 2RCit. Again, this should be amended to 2RCi. The citation of 0. rhizomatica in the Tinderry Nature Reserve (Briggs & Leigh 1996) is incorrect, as the specimen from there is not conspecific (I.R. Telford pers. comm.) The populations of Leptospermum namadgiensis and Olearia rhizomatica on Yaouk Peak do not appear to be threatened, as the area is unsuitable for agricultural purposes.
