THAMES21 - TARGETED HIMALAYAN BALSAM ERADICATION PROGRAMME ON RIVER CRAY.** Revised schedule with date changes**
A couple of the proposed Friday sessions have now been changed to Saturdays, which will hopefully enable people to join in who are not able to make weekdays.
Past attempts to tackle the plentiful Himalayan Balsam on the Cray have jumped around from one location to another, with no sustained effort working from upstream downward. Consequently, plants removed from lower down the river can simply be replaced by seed washed down from further up. Balsam seed only remains viable for a couple of years, so a more disciplined approach could start to clear the river of it.
Michael O'Neill will be leading 6 events in total over this spring and summer period, 3 on the upper stretch of the affected Cray, 3 on the next stretch down.
The upper stretch being from Water Lane off North Cray Road, down to Old Bexley Village, the lower stretch being from Old Bexley Village to the confluence of the river Shuttle, next to Dartfordians Rugby Club.
Dates and links are given below for both the Thames21 website (which carries background details) and for the Plinth event sign up pages.
Please send these dates on to your contacts if you think they would be interested in getting involved, either as a volunteer or to coordinate control works on the Cray river. Any questions, please do let me know.

BARNEHURST SWIFT NESTING AREA - earliest recorded return date.Four, possibly six Swfts were over the area tonight (1/5), between 19.30 and 20.15, my earliest recorded date here. None were seen during an hour of circuits at the same time on 30/4.
The first two spotted were over the Westfield/Midfield junction, flying towards Hillingdon, then again a bit later. Four were observed coming off Barnehurst Golf Course and over Beverley/Northall, two of which appeared to dive down towards a roof on Northall Rd (in the vicinity of a known nesting building), after which no more were seen.
Using data posted to londonbirders.fandom.com/wiki/April_2024
the first Swift seen over London was at the London Wetland Centre on 12th April. There were scattered sightings until 20th April when one was at Rainham Marshes, over the river from Crayford Marshes. Conrad Ellam saw 2 over Southmere Lake on April 21st, with more than 20 at Rainham the same day, 40+here on 23/4 and 100 on 27/4.
2 Swifts were seen from Erith Pier by Tim Rymer on 28/4. There are at least two nest sites nearby, one on Manor Rd. A swift was reported over a known Lewisham nesting area on 29/4 on the Lewisham Swifts Facebook page.
Previous first sightings for the Barnehurst colony were:
2023 - 2/5. My first check of the year so they may have arrived earlier. One reported at Crossness 28/4
2022 -8/5 (checked from 28/4)
2021 - 6/5 (had last checked 3/5)
2020 - 2/5 (first date checked)
2019 - didn't monitor
2018 - 7/5 (had checked every evening starting 1/5)
2017 - 4/5 (no prior daily checks)
2016 - 4/5 (no prior daily checks)
2015 - 6/5 (no prior daily checks)
Worryingly, despite a few visits, no Swifts were seen at two of the very small colonies in Bexley during 2023. One was seen flying away from the Mill Rd (North Heath) site one evening, but that was it, and none were at Silverdale Rd (Bexleyheath. Although the adults may have died, there should still be juveniles out there that were hatched at these locations, so they will be checked again this season.

FRIENDS OF THE RIVER CRAY AT CRAYFORD*** REVISED SCHEDULE ***
Below is the revised schedule for our next few dates (issued 27/4), which involve litter removal and sometimes vegetation management.
The three sessions up to 5/7 are on Fridays and run from 10am to around 12.30 (may be 1pm with packing up). The meeting point is where Barnes Cray Road in Crayford meets Footpath 106 (graphic attached).
3rd May - postponed until 17th May (to avoid clash with River Cray Himalayan Balsam clearance event)
7th June
5th July - postponed until 19th July - (to avoid clash with River Cray Himalayan Balsam clearance event) - (hoildays allowing - I'll see who is available)
Our next session is going to involve undergrowth cutting so long sleeves needed!
2nd August - this session will be on the St Paul's Cray/ Sidcup border, at Ruxley Gravel Pits Nature Reserve, near Foots Cray Tesco's. We will be joining the North West Kent Countryside Partnership for a litter pick on a beautiful site with 3 lakes.
This site is not usually open to the public so it is a fantastic opportunity to see it. We hope to remove all litter from the site, a task started by volunteers in the winter but with water levels too high to finish it.
I am happy to walk you round any of the site you have not seen whilst litter picking. NWKCP is likely to offer lifts from Hall Place - details to follow.
For more details of the Himalayan Balsam work, please see the post of 21/4 on this page.
Best wishes
