LICHEN CHECKLIST FOR THE J.J. COLLETT NATURAL AREA
This list has been compiled by Charles Bird and Janet Marsh based on numerous visits to the area by the former and by the latter’s presence in an outing on September 26, 2010. Both took part in inventories carried out by the Alberta Bryophyte and Lichen Group (ABLIG) on May 1 and October 6, 2013.
Further research will undoubtedly lead to the discovery of additional species.
Lichens are complex life forms which are actually made up of a fungus and an alga, each being so intricately linked that the end result appears to be a plant and is referred to as a species.
Most lichen species are crustose, lacking a lower cortex and being closely attached to a substrate (Candelariella aurella and Xanthomendoza fallax appear to be crustose but they have a lower cortex and are therefore foliose); foliose, more or less thalloid and loosely attached to a substrate; or fruticose, being branched and attached only at one basal point. Most crustose species occur on tree bark, whereas most foliose and fruticose lichens are found either of trees or on the ground.
A number of additional species were found by Kevin Timoney and Anne Robinson in 2009 when they carried out a rare plant survey along the area of the proposed expansion of the road on the eastern margin of the property. These species are indicated with a (+).
Two books are recommended for those wishing to learn more about this interesting group: “Lichens of North America” by Irwin M Brodo, Sylvia Duran Sharnoff and Stephen Sharnoff; and “Mosses, Lichens and Ferns of Northwest North America” by Dale H. Vitt, Janet E. Marsh and Robin B. Bovey.
Though scientific names are normally used, the common names mentioned in Brodo et al. “Lichens of North America” are included.
