The answer in our case is 4 black sacks' worth.

We took a very pleasant stroll along the river Colne, removing the litter we spot to make the route more pleasant for humans and wildlife alike.

Along the way we spotted a woodpecker, heron, water rats, swans and several other less noteworthy species, all while having a good natter and enjoying our local environment.

In support of the Bumblebee Conservation Trust, 7 goodgymers carried out a Beewalk; gathering data on bumblebee populations in Colchester’s Castle Park. Welcoming new members, Sarah and Alexandra, Helen briefed everyone on the purpose of the project and about bee identification. A perfect hot summer evening in the park, we set off from the bandstand on the 2km transect walk. Bronwyn recorded the sightings we all made identifying various species, their caste and population. All Goodgymers chatted about what they were observing whether bee species or plant or flower type; we all learnt new information about common things around us. Stu uploaded the data gathered onto the beewalk database to add much needed support for this wonderful, much needed animal that is becoming increasingly uncommon in our changing world.

7 of us hit the streets and parks of Colchester to remove as much litter as we could. Great to see Ella again, and sorry Vanessa we didn't find you a suitable souvenir!

5 GoodGymers met at the Mercury and headed down towards the Meanwhile Garden outside Firstsite under strict orders not to pick any litter up on the way. We couldn't resist however when we noticed a whole load of blue roll and paper blowing about (presumably a split recycling bag) and made a swift improvement to the precinct.

We were pleasantly surprised that the Meanwhile Garden had much less litter than last time we were there, and we were even helped out by a member of the public who was enjoying the garden and wanted to make sure it stayed that way.

We headed down East Hill, this time taking our time to chat and pick up bits on the way and then finished off clearing the area around a children's play park near the river.

Top points for interesting finds go to Haidee and the abandoned jacket and Vanessa and an abandoned Octopus. Lovely to meet Ian for the first time as well.

There's no task next Tuesday, but we will be at the Junior Park Run this Sunday, and then back in town Tuesday 2nd June to clear the planters ready for summer bedding.

Four Goodgymers scoured the town for trash this evening, on a beautiful if rather chilly April evening. We headed east, via the Meanwhile garden in the cultural quarter, towards East Bay. We found lots of grot in the bushes and across the grass near a children's play area, and felt a warm glow of satisfaction from cleaning up the area for all the park users. Notable finds included a strawberry, a felted pumpkin, and a toaster. Wildlife encounters included trills from a Cetti's warbler, sleepy swans by the pond, and a curious fox, checking us out.

3 GoodGymers met to tackle some of the litter in our city.

We were amazed at the number of cigarette butts we found and wondered what would need to happen to stop people leaving them on the ground.

I like to think we helped people on their way into town work this morning feel a little more positive about their town, and that fewer animals were harmed by litter last night.

As well as being productive I found it a very educational GoodGym, learning a lot about East Anglia and education from Vanessa and Ray!

This Sunday we are helping out with the Junior Park Run and then on Tuesday we are delivering leaflets for Mind. Sign up now if you can!
