Welcome to the Consortium of North American Lichen Herbaria

The Consortium of North American Lichen Herbaria (CNALH) was created to serve as a gateway to distributed data resources of interest to the taxonomic and environmental research community in North America. Through a common web interface, we offer tools to locate, access and work with a variety of data, such as keying to species.
News and Events
  • NSF Press Release 11-136 - US National Science Foundation awarded support to a collaboration of herbaria in order to database ca. 2.3 million North American lichen and bryophyte specimens (NSF ADBC 1115116)
  • September 2011 - 543302 occurrence records integrated into data portal supplied by 15 different data providers
The CNALH data portal is more than just a web site - it is a suite of data access technologies and a distributed network of universities, botanical gardens, museums and agencies that provide taxonomic and environmental information. Initially created to integrate databases between Arizona State University and the Santa Barbara Botantical Garden, the consortium is growing to extend its network to other partners within North America.
