Exotic & Invasive plants by Lawsons Brook (Williams Lake) in Halifax NS, July 20/21, 2023

I conducted an "opportunistic"survey of exotic and invasive species (as well as recording what else is there) on Lawsons Brook, the stream draining Williams Lake on the Halifax south mainland on July 20, 2023. I returned on July 21 to sort out some observations in the initial sections, these days during breaks in an an incredible deluge of precipitation over a few weeks. So the photos show Lawsons Brook with a lot of water, unusual for mid-summer in years past.

It is a beautiful yellow birch-lined wet riparian corridor that has escaped recent fires (last 70+ years) . It has a history of industrial use in settler times.

There are 14 "sections" proceeding from Purcells Cove Road to Williams Lake: 00, 0-1, 1-2, 2-3, 3-4, 4-5, 5-6, 6-7, 7-9, 8-9, 9-10, 10-11, 11-12, 12-13. More details to follow. The Lat & Longs are prob +/- up to 10-20m, (Olympus Tough TG4 camera) re: forest canopy. I have Garmin GPS readings for section positions, 'will post those later, also some of the native species.

Invasive species uploaded to date are listed under the tag InvExoSurvey20Jy2023LawsonBk
