Plants of the Credit River Watershed
A vascular plant flora has been compiled for the Region of Peel and the
Credit River watershed, based largely on an updating of the Peel
County flora published by Jocelyn Webber in 1984. Published floras for
jurisdictions adjacent to Peel, including the Regional Municipality of
Halton (Crins, 1986) and Wellington County (Stroud, 1941) were
examined for relevant records within the Credit River watershed and a
large number of naturalists and botanical specialists were consulted to
identify additional data and records of vascular plants in the areas
under consideration.
A total of 1205 vascular plant species were identified as growing
outside cultivation in the jurisdiction of the Credit Valley Conservation
(CVC). In these local floras, 780 are native species in the CVC within
the Credit River watershed, two vascular plants have been designated
species of special concern by the Committee on the Status of
Endangered Wildlife in Canada, ginseng (Panax quinquefolius) and a
pondweed (Potamogeton hillii). Fifteen (15) species within the Credit
River watershed are considered provincially rare by the Ministry of
Natural Resources. A relatively large proportion of the native species,
in total 335 species, are considered rare in the Greater Toronto Area
while 402 are rare within the watershed.
The following tables summarize the
vascular plant flora in the Credit
River watershed and Peel Region
and their status.
