There are two campaigns for this May.
First up, Plantlife’s No Mow May is back. Basically, we don’t mow our lawns (or even a patch of lawn) throughout May, and then do a flower count of the unmown area at the end of the month. They have been doing this for some years now – simple to do, but it provides valuable information and gives small plants a chance to flower and provide a source of nectar for bees and other insects.
The other campaign is being run by Greenpeace who are running a Big Plastic Count between 16 and 22 May. They say:
Count your plastic for one week – 16-22 May 2022.
Across the country, households of all shapes and sizes, schools, community groups and businesses, will gather new evidence. How much plastic are we really having to throw away, and what happens to it?
We’ll show the government it’s time to commit: reduce single plastic use by 50% by 2025 by switching to reusable options that work for everyone – and ban sending our waste to other countries.
