Delphinium caseyi
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Delphinium caseyi faces severe threats from habitat destruction due to urban development and agricultural expansion in its limited California range. The species is particularly vulnerable to invasive plant species that outcompete it for resources and alter soil chemistry. Climate change poses an additional threat through altered precipitation patterns and increased drought frequency, which directly impacts this moisture-dependent perennial herb.
Habitat
Delphinium caseyi inhabits grasslands, oak woodlands, and chaparral margins in coastal California, typically growing in well-drained soils on slopes and hillsides. The species requires specific soil conditions and moisture regimes found in Mediterranean climate zones with cool, wet winters and dry summers.
