Range in Ontario is wrong

[edit]

The range in Ontario, Canada is a bit wrong. Black walnuts occur significantly farther out than this map indicates. Here is the range map of non-planted black walnut discovered by the University of Guelph: [1]. In the east they're relatively common in the Bay of Quinte area (I had quite a few of them growing wild in Quinte West, Ontario) and the entire Lake Ontario shoreline extending into the Thousand Islands, and along the Rideau & Mississippi river system as far north as Ottawa (there's a large natural grove on Lemieux Island on the Ottawa river, even: [2]) and as far inland as Almonte. They occur sporadically throughout inland eastern Ontario: some towns I know they're to be found around are Cumberland, Riceville, Chesterville, Kemptville, Maxville and Cornwall. In the west they occur far more north than is indicated as well, covering pretty much the entirety of southwestern Ontario up to Wiarton on the Bruce Peninsula and Huntsville in the Muskokas with their northern limit being roughly the Trent-Severn waterway. There are even a few noted groves along the North Channel of Lake Huron in the Sault Ste Marie area, and around Pembroke in the upper Ottawa, though whether they are planted or not is up for debate. - Oosting (talk) 03:47, 14 January 2017 (UTC)[reply]
