From the text...”Unlike the flat-rock areas in the southern Appalachians, where the foundation for research on rock barrens was established many decades ago (e.g., Harper 1939; Oosting and Anderson 1939; McVaugh 1943) and has been followed by more recent cornprehensive ecological studies, the foundation for research on rock barrens in Ontario is still incomplete. Until recently, no attempt has been made to classify dry granite rock barrens in Ontario or to characterize their major associations in a comprehensive manner. Characterization of the barrens flora and fauna currently is limited to several consultant reports designed to assist in establishing a network of protected sites (e.g., Browncll 1984, 1994, 1997a, b; Macdonald 1986; Varga 1988; Bergsma 1994; White 1994, 1995a. b). Ecological studies are essentially lacking, with the exception of those concerning the barrens near Sudbury that resulted from smelter emissions (Freedman 1989, pp. 30-39). An understanding of the significance of granite rock barrens was so incomplete that there was no research aimed at determining the effect of spraying Bacillus thuringensis on the community as a whole, either prior to or during the spray program to control gypsy moth. This is a lamentable situation considering current world commitments to the protection of biodiversitv. Research is essential with regard to potential influences such as the construction of dams and the limitations on natural water level fluctuations, as well as spraying to control insects. Apart from the research essential to effectively manage barrens landscapes. there are some very promising opportunities involving evolution of specialized ecotypes, drought tolerance, environmental monitoring, and comparison with better-studied nonglaciated sites further south.”
