Lapwings and skylarks are common at Cley Marshes reserve
Norfolk's biggest wildlife recording event is hoping to note more than 500 species in our countryside to help protect their future.
A BBC Springwatch Wild Day Out is taking place at Norfolk Wildlife Trust reserves on 5 and 6 June for 24 hours.
"The results of surveys provide vital information to help protect our wildlife," said Springwatch presenter Kate Humble.
Nature lovers can get involved for free from 12pm on the Saturday.
"All you have to do is identify as many species as you can at a Norfolk Wildlife Trust nature reserve: birds, mammals, insects, plants: any species you can identify with certainty, then send us your sightings," said the trust's educational manager David North.
Recording forms will be available at all the 50 Norfolk Wildlife Trust visitor centres or can be downloaded on this page.
All sightings will be submitted to the Norfolk Biodiversity Information Service to be added to the knowledge of species' distribution in the county.
If you love nature but need help identifying the wildlife, 11 reserves are holding guided walks led by experts to provide a chance to see Norfolk's wildlife at its best.
"We really hope the people of Norfolk are inspired to come and join us to record our local wildlife. Every pair of eyes counts and every species they see counts too: ant or avocet, beetle or bittern, crane or cranefly," said David.
If you cannot get to your nearest reserve during the weekend then you can listen to the progress of the survey at Cley Marshes with BBC Radio Norfolk.
Andy Archer's Garden Party will be live from Cley on Saturday, 5 June, from 12 to 2pm and Maggie Secker will also be doing her bit for the county's wildlife as she broadcasts live on Sunday from 3 to 6pm.
Radio reporter Jill Bennett will also be at Cley giving updates throughout the weekend.
You can listen to BBC Radio Norfolk on 95.1, 95.6 and 104.4 FM, 855 and 873 MW, DAB and
Norfolk Wildlife Trust will also be updating the finds on their website and Twitter page.
There are many other wildlife events taking place across the county over the same weekend with BBC Breathing Places, including a mini-beast family day at Holkham National Nature Reserve. More information is on the
Breathing Places website.
