Habitat

Habitat requirements

Generally, Juncus kelloggii is found in seasonally wet depressions and vernal pools throughout its range. It is often found in low spots in fields and meadows. Plants growing with this species in British Columbia include chaffweed (Anagallis minima), the red-listed species Centaurium muehlenbergii, Heterocodon rariflorum, Juncus bufonius and the red-listed species Psilocarphus elatior (BC CDC HERB database 2002; Douglas et al. 2002). Elevations: to 10 m.

Trends

There is one extant population of J. kelloggii in Canada in the Victoria area. This population contains up to several hundred plants (RBCM Herbarium records; Table 1). There are no historic records for this species; the first record is from June 1985 (CDC HERB database 2002; Douglas et al. 2002). Considering its tiny size, highly restricted occurrence and presence in a habitat with numerous other rare species it has likely been present for a long period of time.

Protection/ownership

The single Juncus kelloggii population is found within a regional park in the Municipality of Oak Bay within Victoria. Currently, there is no management plan for the park (L. Middleton, pers. comm.).
