Carex Working Group
The Carex Working Group formed in 1993 out of a common
interest in the genus Carex (sedges) and to work toward the following
· learn to identify all Oregon Carex, the state’s largest genus of vascular
· explore areas of the state where Carex distribution was not
· deverlop a database of Carex herbarium specimens
and location records
· create range maps for all Oregon Carex taxa
· assess current status of Carex populations
· develop a field guide to Carex of Oregon and Washington
The Carex Working
Group has annotated all Oregon Carex in the OSU herbarium and many of the other
herbaria around the state. They have
built a database of over 6000 entries which includes information both from
herbarium specimens and from Carex sighting records accumulated during field
work in many parts of the state. With
the aid of Dr. Jon Kimmerling (Geosciences), Manuela Huso (Forest Science), and
the Oregon Flora Project they have used this database to produce the Atlas of Oregon Carex which contains distribution maps for all Oregon Carex taxa.
Members of the Carex Working Group have described a new species that
occurs in southern Oregon (Carex serpenticola), and have written several regional Carex and Juncus keys.
In addition, they have provided input to the Oregon Natural Heritage
Information Center (ORNHIC) on rare Carex taxa of Oregon.
Currently, more than 30 rare Carex
taxa occur on ORNHIC lists,
attesting to the importance of the biogeographical information provided by the
Carex Working Group for this difficult genus.
Current projects include taxonomic work on several troublesome species
groups, conducting Carex inventories in Oregon, northern California and Washington, and production of A Field Guide to Carex of Oregon and Washington.
The Carex Working Group has been funded by generous grants from the
Native Plant Society of Oregon and has been greatly aided by support and
cooperation from the OSU Herbarium. More

The Atlas of Oregon
Carex has 128 shaded
relief range maps, one for each Oregon Carex taxon.
Also included are synonymy, fun facts about sedges, a history of the
project, and maps of Oregon geographical features. This
publication, which incorporates historical records as well as those accumulated
from an additional seven years of sedging by the CWG in Oregon, was the first Occasional Paper of the
Native Plant Society of Oregon (NPSO).
All proceeds are from sales of the Atlas are donated to the
NPSO. The Atlas is available by
sending a $5 check payable to NPSO to:
