Based on data from 10 collection localities, its climate preferences include a mean annual temperature of 21°C, with an average minimum in the coldest month of 12°C, and a mean annual precipitation of 1620 mm (Biffin et al. 2011, Table S5). Zone 10 (cold hardiness limit between -1°C and +4.4°C) (Bannister and Neuner 2001).

The species occurs in a state forest reserve. Conservation status is classified as "lower risk - conservation dependent" (Conifer Specialist Group 1998).
