- April 22nd NI: Walk length and found none, but see Northern Bund post.
- April 22nd W1: 11 just north of boat
- April 26th W2: 0!A little distracted
- June 27th: N1: Cleared the bund in the northern field, part of Riverland and found no plants; so it is a mystery as to what the white patch could be on the image taken last year (three quarters of the way down on edge of riverbank).
- June 26th N1: (1) Whilst clearing the bund as part of the Himalayan Balsam sweep I came across one plant growing out of the edge of the bund, river-side, at the eastern edge of the worked area, I will check the remaining roots embedded in the side of the bank in a week or two to decide if to attack the bank with a spade. A few days ago I noticed a white patch whilst making up a new map for the Himalayan Balsam work in Riverland, so will make efforts shortly to get there.
May 25th W2: (3) At last I've been down the marsh, prompted partly by checking the swamp and dawn cypresses. Found 3 GHW in the old A area near the trees mentioned and 1 further away in the old B area. None others found but then there is a lot of overgrowth as I have left it so late.

Given the changing landmarks and regular low numbers I am relabelling the Hogweed Sites. Lettered plots to the west of the boat.
W1, previously A, G, H and 3
W2, previously B, C D, E, F and the western marsh boundary Numbered plots to the north of the boat.
N1, previously 1, 2, 4, 5, 6, 7, and 8 First scouring was done on 22nd April and given the warm and wet weather there were a few plants a foot or more in height. Over all compared to last year there are a few more.
May 30th N1 (1 in old site 8)

April 23rd W1 (176) There was a dense patch just north and adjacent the boat. Looks like a head full of seed landed there sometime. Bit of a pain as they were amongst brambles and blackthorn and on a muddy slope.

Why they are deemed a problem? Ragwort is poisonous for horses and cattle, although not it seems for the deer at ELF. Humans can also suffer from cirrhosis of the liver if it is handled sufficiently.
The legal case. The Weeds Act 1959, amended by the Ragwort Control Act 2003, aims to prevent the spread of Common Ragwort. It provides powers for the Secretary of State, any person acting on their behalf or the Secretary of State for Environment, Food and Rural Affairs, to prevent the spread of Ragwort on private land, which, if not adhered to by the owner of affected land, can lead to a fine up to £1000 and further punishment.
and Code of Practice on How to Prevent the Spread of Ragwort (PDF)
Although only one of five plants listed in the 1959 Weed Act, ragwort is regularly rooted for removal. The reasons are, arguably, a) it is more toxic, b) more noticeable with it's bright yellow flowers and c)is more able to spread further afield with it's parachute headed seeds.
.... when tested in a variety of conditions, 31% of the seeds travelled only 1 metre, 89% of them 5 metres or less and none were collected more than 14 metres from the source. The study involved studying the dispersal of over fifty three thousand individual seeds. ragwortfacts.com
The management on this land.
The ragwort is pulled up and bagged. Care has to be taken in not leaving viable root parts. SeeJuly 17th 2015.
The original fields, those to the south of the main drag, seem all but cleared of ragwort, so there is some relief that all the effort worked and is still noticeable.
Most of the weed is pulled from the bottom of the Triangle Field; 90% of which is the area to the south of the path to the Far Fields.
