Peacock vinyl (Leptogium polycarpum) is a leafy, gelatinous (jellyskinned) lichen forming patches 2?5 cm in diameter. Lobes are rounded to orbicular in shape. The upper surface is pale to dark greyish or brown, shiny, hairless with partly sunken spore-bearing bodies, and wrinkled when dry. The lower surface is paler than the upper surface, and can either be naked or with tufts of white hairs.
Peacock vinyl was designated as Special Concern by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) owing to its restricted distribution and population size. It occurs only in the coastal forests of southwestern British Columbia and in one isolated location in Haida Gwaii, where it is found growing on the mossy branches of deciduous trees, especially Bigleaf Maple and Red Alder.
The species is not yet listed on Schedule 1 of the Species at Risk Act (SARA). In British Columbia, peacock vinyl is ranked S1S2 (critically imperiled to imperiled) by the B.C. Conservation Data Centre and is on the provincial Red list. The B.C. Conservation Framework ranks peacock vinyl as a priority 1 under goals 1 and 3 (1 = contribute to global efforts for species and ecosystem conservation; 3 = maintain the diversity of native species and ecosystems).
Threats to this sensitive lichen include air pollution from industrial and agricultural activities, forestry and associated infrastructure, as well as drought and storms and flooding due to climate change.
The management goal is to maintain all known extant populations and any future populations of peacock vinyl that may be found in British Columbia.
The following are the management objectives:
1.to secure long-term protection for the known populations and habitats of peacock vinyl;
2.to determine the levels of real and potential threats to this species and its habitat and to mitigate their effects;
3.to confirm the distribution of peacock vinyl (including new locations) and to reliably determine population trends.
