Main challenges
- Summer heat — heat-stress precautions needed in Jul–Aug
- Dry climate — only 10 in of rain — irrigated pasture or year-round hay
- Low selenium — regional soils and hay tend to be selenium-deficient
Advantages
- Winters are cold but rarely severe
- Short or no barber pole worm transmission season
- Low meningeal worm risk
Overall rating: 87/100 — Excellent on our alpaca climate comfort score. Climate type: Cold semi-arid (Köppen BSk).

- Barber pole worm: low transmission risk on average — still run fecal egg counts in spring and autumn.
- Freezing nights: Nov–Feb — keep water from freezing.
- Vitamin D for crias: Oct–Mar.
- Grazing season: Mar–May (about 3 months); feed hay the rest of the year.
- Meningeal worm: Meningeal worm is not established in this region.
