Said here to be "well adapted to [a] cold dry climate" (see last sentence under Distribution and Ecology).

Embothrium, thanks for the link. It seems to me that several species of Juniperus mingle together or in close proximity in that area of high altitude mountains. I´m no expert but J. pingii, J. recurva and J. komarovii look like they thrive in rocky & dry but cool environments.

The one I posted above is certainly not in a dry area, at least receiving 1000 mm (40") per year.

Yes.
