Habitat and Ecology
In the Himalaya, Cupressus torulosa is a codominant with Juniperus in the dry inner valleys and semi-arid high mountain environments towards the Tibetan side of the main range, where this open forest or woodland type occupies S-facing slopes. The altitudinal range is 1560-3670 m a.s.l. Annual precipitation does not exceed 300 mm, most of which falls in summer and autumn. North of the Himalaya, in the Tibetan valleys that drain south through the Himalaya chain or north and east into the Zhangbo system, conditions are too dry, but eastwards along the Zhangbo River downstream from Gyangze C. torulosa is again found in isolated stands. Here we also find C. torulosa var. gigantea which is perhaps a xeromorphic form of C. torulosa (S. Miehe pers. comm. May 2001, who claims to have seen both forms growing together).

Justification

The area of occupancy (AOO) cannot be reliably estimated due to the lack of detailed knowledge of the species’ occurrence in areas where it is indigenous. The species has an extent of occurrence (EOO) of over 5 million km2, though with a significant gap in the distribution between central Nepal and SE Tibet. Based on the data available, it is not possible to justify the Near Threatened category as none of the criteria are met in whole or in part for the category of Vulnerable. It is therefore assessed as Least Concern.
