The legend says that it was at Brent River Park's 50th birthday when Kash from GoodGym and Ben, the leader of Clean Up River Brent, fixed a date for a joint wading event in Pitshanger. When the day came, it became clear that the theme would be the famed balsam bash - the removal of invasive plants with stalks like giant celery and purple flowers of stunning beauty. The gorgeous flowers were particularly troublesome as they were starting to explode, sending hundreds of Himalayan Balsam seeds into the air and water.

The Balsam Bashers group assembled on Sunday morning at Pitshanger Park Bowls Pavilion. Rachel, Lara, Bob, and Martin were busy choosing the right size of waders and listening to Ben's health and safety brief. GoodGymers Sevan, Steph, and Kash were already in the park, after volunteering at junior parkrun and queuing for coffee at the park café. Kymm from GoodGym Hounslow, experienced with balsam bashing, joined them shortly to try on waders for the first time. The pair she got was not the most comfortable to walk in.

Kymm: "Are they supposed to be that harsh on the feet?"
Ben: "Is it some sort of grit? I actually like it, but I'm a masochist."

Comfortable or not, waders were worn by everyone to protect skin from Weil's disease and other nastiness hidden in contaminated water. They also shielded us from brambles, nettles, and even giant hogweed. With long rubber gloves, wading poles, and hi-viz, the team was ready for a serious adventure. We wandered west along the River Brent and found a suitable place to carefully descend from the bank. On a hot day, the water felt nice and cool through the waders.

Guided by the wading poles to avoid the treacherous drops in the river bed, we walked downstream, bashing the balsam on the way, some of us from the water, others occasionally from the bank. We went as far as the footbridge leading to St Benedict's School. Before heading off, we took with us some imposing balsam specimens for a special photoshoot by Martin Sapsed for his project documenting the work of volunteers across different fields. Sadly, we had to remove the best-looking flowers to minimise the risk of balsam seeding on the way. We think we still made quite an impression on the park visitors.

Passer-by: "It looks like a religious festival!"

Our pagan procession returned to the pavilion, where Martin assembled us for a carefully designed Balsam Basher group shot.

Martin: "I'm looking for a look of grim determination."

We gave Martin the most serious stares we could muster, then happily took off the waders as we felt we were starting to boil after having left the cooling water. Some would describe the atmosphere of getting released from waders as whiffy. Ben said it's been a year with the most wading involved so far and promised to give the rubbery equipment a thorough wash before the next session. We're looking forward to another CURB event to do good for biodiversity in Ealing and sweat in fresh waders again!
