Lavforekomstmiljøer

Lavforekomstmiljøer is a term used in Norwegian environmental science to describe environments characterized by low occurrence or low abundance of organisms, resources, or ecological features. The word combines lav (low), forekomst (occurrence), and miljøer (environments). It is used across disciplines to denote habitats or conditions where elements of ecological communities are rare or infrequent, in contrast to more common or productive environments.

In practice, lavforekomstmiljøer may refer to habitats with sparse species richness, low biomass, or scarce resources, such as high‑altitude screes, desert‑like microhabitats, subterranean caves, or temporary pools that are present only seasonally. The concept is often relevant to conservation and impact assessment, since rare or fragile environments may be more sensitive to disturbance and may host rare or endemic species. It also informs mapping and evaluation of habitat value within land‑use planning and nature protection efforts.

Definitions and thresholds for what constitutes a lav forekomst environment vary by region, taxon, and context, so researchers and policymakers typically specify criteria in each study or plan. The term supports prioritization in conservation by highlighting habitats with limited occurrence that may require targeted protection measures or careful management to preserve ecological diversity.

Research on lavforekomstmiljøer often focuses on identifying limiting factors that constrain occurrence, developing monitoring approaches for rare habitats, and integrating rarity considerations into biodiversity strategies and policy. The concept underscores the importance of recognizing and protecting environments that host comparatively scarce ecological resources.
