Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
Sporodophoron cretaceum faces severe population declines due to widespread habitat destruction from agricultural expansion and urban development across its limited range. The species' specialized ecological requirements and small, fragmented populations make it extremely vulnerable to environmental changes and stochastic events.
Key Facts
Habitat & Distribution
Inhabits specialized calcareous substrates in temperate grasslands and open woodlands, typically on limestone outcrops and chalk downs between 200-800m elevation. Requires specific soil chemistry and moisture conditions that support its unique ecological niche.
Threats
