now Saskatchewan which were published in Macoun (1902). .After Macoun's work there
was a long lapse in collecting activity in the grassland areas of Saskatchewan until
1961-1973 when significant contributions to the grassland lichen flora of Saskatchewan
were made by Looman (1962a.b, 1964, 1964a.b.c, 1969) working out of the federal
government agricultural research station in Swift Current.
Several authors published reports on Saskatchewan boreal forest lichens in the 1960s.
The major collectors included: Thomson and Scotter, reporting lichens from the Black
Lake area in the Selwyn and Tazin Lake Upland Ecoregions (1961), George Argus, who
made small lichen collections on Beartooth Island, Lake Athabasca (Argus 1964) and at
Carswell Lake area (Argus 1966a). All of these sites fall into the Taiga Shield ecozone.
In the late 1960s, the lichen flora of the province was summarized by Bird in his
catalogue and keys to the lichen flora of the three Canadian Prairie Provinces (Bird
1970, 1972). At the end of the decade, Jesberger and Sheard (1972) carried out a
quantitative and multivariate analysis of corticolous lichens on the southern edge of the
Boreal Plain Ecozone (i.e., Prince Albert National Park and Candle Lake Provincial
Park).Vernon L. Harms, assisted by R.A. Wright, expanded the areal extend of lichen
collections in boreal Saskatchewan with surveys carried out for the environmental
impact assessments of several uranium mines located in the Boreal Shield Ecozone.
These studies included work near Collins bay and Hidden bay on the west shore of
Wollaston Lake (Harms 1977) and Cluff Lake (Harms 1978). Their study on the Taiga
Shield near Uranium City (Harms 1982) provided specimens from this rugged
landscape on the north shore of Lake Athabasca. Jonescu (1970) did a study of lichens
on Populus tremloides, while Sheard & Jonescu. 1974 did a multivariate analysis on the
distribution of lichens on Populus tremuloides .
The 1990s saw a systematic collection effort from the Saskatchewan Provincial Parks
system. Wright et al. (1995) listed lichens collected in a variety of forest types in Duck
Mountain Provincial Park, while de Vries (1992) did a biodiversity study on North
American Lichen distribution patterns in the same park (unpublished manuscript).
Species lists were produced from surveys in Candle Lake Provincial Park (de Vries
1994, Wright et al. 1999b) and Narrow Hills Provincial Park (de Vries 1995, Wright et al.
2000). de Vries also collected along the Hanson Lake Road in both the Boreal Plain and
Boreal Shield Ecozones (de Vries, unpublished manuscripts). Systematic collections of
lichens were also done during the Forest Ecosystem Classification Surveys (de Vries
1999-2005). Additional lichen surveys were made by de Vries in Brandon Nature
Sanctuary in the Boreal Transition ecoregion of the Boreal Plain Ecozone, Maurice G.
Street Wildlife Sanctuary in the Boreal Transition Ecoregion of the Boreal Plain
Ecozone, Rendek Elm Forest in the Mid-Boreal Lowland Ecoregion of the Boreal Plain
Ecozone, Turtle Lake Nature Sanctuary in the Mid-Boreal Upland Ecoregion of the
Boreal Plain Ecozone, van Brienen Land Nature Sanctuary Aspen Parkland Ecoregion
in the Prairie Ecozone (unpublished manuscripts), and Crooked Lake Fen Nature
Sanctuary in the Aspen Prairie Ecoregion of the Prairie Ecozone (de Vries 2003).
Collections from the Porcupine Hills in east-central Saskatchewan in 2004 were also
identified by de Vries and rare and endangered lichens and sustainable lichen habitat in
the grasslands, aspen parkland and southern boreal forest are being assessed in
