Mapperley Golf Course Car Park (entrance at the end of Central Avenue, off Plains Road NG3 5LD). Start time: 9.30 am:

We meet in the car park. This session is all on dry land and involves pulling plants out – for those who have not done this before, it is easy work as the plants are small at the moment with shallow roots. Gloves are essential as there are nettles about as well (I will have a limited number of pairs).

The golf course is the main source of the seeds that spread down stream each year so we need to completely eradicate the balsam from here if we are to reach a permanent solution.

Together, we are really making a difference at the dyke and the wildlife is getting a chance to flourish.
