Non-vascular Plant Information
Available from the Washington Natural Heritage Program

Basis for inclusion

All mosses, lichens, macrofungi, and marine algae included in this section are native to Washington. The lists for each major taxonomic group were developed by scientists using the same criteria as those used for vascular plants: occurrence pattern, vulnerability, threats, degree of protection, and taxonomy. A statement acknowledging contributors accompanies each individual list.

Priority groups

At present, there is insufficient information, both in terms of inventory and degree of threat, to assign a statewide status (e.g., Endangered) to most of the non-vascular taxa, as has been done with vascular plants. It is our hope that enough information will be gathered in the near future so that these working lists can be refined and a statewide status assigned. In the meantime, the lichen and macrofungi lists have been divided into two priority groups based on an assessment of the criteria mentioned above. The mosses and marine algae are not separated into priority groups.

Format

The major taxonomic groups (i.e., mosses, lichens, macrofungi, and marine algae) have been listed separately. Within each group, the taxa are listed alphabetically by scientific name. A statement about nomenclature within each group is included at the start of each list.

The other entries included for each taxon vary by taxonomic group, depending upon the information supplied to the Washington Natural Heritage Program (WNHP) by those who developed the list for that group. Global and state ranks have been assigned for some mosses, lichens and macrofungi. Neither global or state ranks have been assigned to the marine algae. Those ranks which have been assigned should be considered preliminary. As more information is gathered in the coming years, these ranks will be refined.
