Main challenges
- Low selenium — regional soils and hay tend to be selenium-deficient
Advantages
- Summers rarely reach heat-stress levels for alpacas
- Winters are cold but rarely severe
- Short or no barber pole worm transmission season
- Low meningeal worm risk
Overall rating: 98/100 — Excellent on our alpaca climate comfort score. Climate type: Mediterranean-influenced warm-summer continental (Köppen Dsb).
