A second giant hogweed infestation was found just a few metres from the kiddies’ playground. We sprayed perhaps 80-100 plants. We then checked out a report of a single giant hogweed plant at Prospect Road, and dug that one out in a jiffy. After checking the tire pressures on the truck – three being about 20psi too high and the fourth about 10psi too low – we were off to Mosquito Creek in William Griffin Park; a popular dog-walking trail to the west side of the creek and a less-used trail to the east side formed our basic boundary, with the giant hogweeds – roughly 100 – growing all along the creek sides and islands in between. Taking extra care as this is valuable fish habitat we stem-injected or sprayed the plants. That took about 2 hours, as we had to negotiate slippery boulders and watercourses as well as find and expose the plants hidden in the dense undergrowth. After a lunch break we headed up to Windsor and St Ives, whjere a reported giant hogweed had disappeared due to drain and road works, so afterchatting with the site foreman we quickly treated a small clump of Japanese knotweed growing in very close proximity to the intended disturbance limit. Then off to Balmoral School where we treated 11 giant hogweeds on a trail running around the school grounds, But nothing quite prepared us for what we found on the shortcut from the school to Everglade/Evergreen Place – a veritable hogweed forest some 50m x 10m or thereabouts, most plants around 2m tall but a couple flowering at 3m of so, with the shortcut trail running through. The shortcut had been closed off with some plastic snow fencing and a “Danger Do Not Enter” tape at both ends of the trail, but it was clear that this had been breached at least a few times recently. After snipping off the flower heads and bagging them, and removing a few face-level leaves here and there, we set to work. About an hour and a half, we estimate we treated several hundreds of plants over an area about 50m x 10m –somewhere in the order of 500 or more plants, we pretty much gave up trying to count – with sprayed plants identified by a splash of orange paint. One of the local homeowners came out to see what we were up to, and mentioned the school kids keep using the short cut; hopefully the giant hogweed plants will be dead before school starts again. Pics to come later today.

Giant hogweeds that bit the dust: about 700 would be a fairly conservative estimate
Today we started work in the north-west reaches of the District of North Vancouver, focusing on giant hogweed. After a quick recce of a few sites we started out at Cleveland Park where a worrisome patch of giant hogweed is growing up and under the staircase that leads from the parking area to the soccer field. Just waiting to be smashed up by many pairs of feet it was easy to imagine the harm it could do if anyone was wearing flip-flops.
