These populations are continuously augmented by propagules through railway shipments of grain from the prairies to the elevators. In the more boreal zone of Central Quebec and Labrador (centered on 54 °N latitude), Hustich (1971, 1972) estimated that about 100 species or about 15% of the vascular plant flora was introduced. Most of the non-native species were of temperate origin and tended to be restricted to northern microhabitats that were heavily disturbed by roads, railways, communities and Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Ottawa Field-Naturalists' Club.
