The Doncaster Nats Phenology project has been running since 2002 and we will have gathered some useful data on when Spring has arrived in Doncaster over that time.
Nats member Mick Townsend is collating members records and will now be pleased to receive contributions for 2021. Contributions for any of the records are welcomed, (or any past records).
A copy of the Phenology Form can be found here.
