- Limited insolation from sun due to curviture of the Earth, leading to low amounts of photosynthesis
- Very short days in winter due to tilt of the Earth
- High winds=High transpiration rate+plant damage due to abrasion
- Unavailable water
- No/thin soil due to lack of weathering+low NPP meaning limited minerals and nutrients
How does this make these environments fragile?
- Limited insolation=plants are limited in photosynthesis=lack of energy available=if destroyed can't be replaced (due to low NPP and recovery rates)=leading to a high proportional impact
