Kellogg’s rush (Juncus kelloggii) COSEWIC assessment and status report: chapter 11
Summary of status report
Juncus kelloggii is restricted to southeastern Vancouver Island and is known from only one locality in a municipal park, Uplands Park, in Victoria, British Columbia. Kellogg’s rush is uncommon in southwest Oregon and California. The population at Uplands Park contains up to several hundred individuals, and has remained stable for the past fifteen years. It undergoes considerable population fluctuation with larger numbers of plants present when adequate moisture is available. The species is found in seasonally wet depressions and vernal pools through its range. It is an annual species that requires sites that are moist to wet in the winter and spring and dry during the summer. These vernal pool communities are fragile and subject to alteration. Juncus kelloggii is potentially overlooked due to its diminutive size and similarity to another annual species Juncus bufonius.
