Location climate

Site climate is a small-scale climate related to biological relationships.

Within a forest , over a field or in a crevice, different climatic conditions ( temperature , humidity , UV radiation , wind ) occur than in the protected weather hut two meters above the ground.

This fact allows plants to exist in favored locations outside their area , a phenomenon that Heinrich Walter introduced into geobotanical terminology in 1953 as the law of relative constancy of location .
