This rat is common in the Joshua tree and juniper belts, and locally penetrates the pinyon belt at about 5000 feet elevation.
I've been down to pinyon's to-day, with my croshy-work, for a change.
Shrubs become more abundant and pinyon and juniper trees become less abundant as one approaches the drainage.
Many of the flats of the pinyon belt are grown to basin sagebrush.
pinyon pine trees tend to decay from the outside and were not used as nesting sites by P. truei.
Many a time before had they rounded up their herds and stalked the deer among the thin cedar and pinyon forests.
Cedar and pinyon trees lined the trail, and there were no more firs.
On that slope anything that started rolling never stopped unless it went against one of the rare pine or pinyon trees.
It was a dry region, but with plenty of grama-grass, and much of it covered with an open forest of pinyon and cedar.
Another species of the same genus, the pinyon mouse, P. truei, also lives on the Mesa Verde.
