Wales Garden BioBlitz is back for Wales Nature Week 2021!

To kick off Wales Nature Week, join LERC Wales* staff for a national nature hunt in your own garden! On Saturday 29th May, wildlife lovers across Wales are invited “BioBlitz” their garden, by looking for species common and rare to contribute to our Wales wide species snapshot.

When: Saturday 29th May Midnight – Midnight

Where: Your own garden (or a local park)

What: Record all the species you can find in your garden for 24 hours to build a national species snapshot for Wales Nature Week

How: Follow the fun on Facebook and Twitter with #WalesGardenBioBlitz21 and send us your garden species records via the LERC Wales App (or alternative recording route**)

Why: Have fun learning about the nature in your garden, and contribute useful data to help wildlife conservation.

*LERC Wales is a consortium of the four Local Environmental Records Centres in Wales: BISCofnodSEWBReC and WWBIC. Each LERC collates wildlife records for their area of Wales, and provides this information to decision makers whilst supporting the local recording community.

**We will be counting all records received for 29th May as part of the event. If you are an established recorder, please use your preferred submission method, e.g. iRecord or your LERC’s online system. If you are new to recording, we suggest the LERC Wales App as the easiest method of sending us data. Alternatively download this spreadsheet and return it to
