HELP record species of wildlife and have fun at the same time.
Queen Elizabeth Country Park, near Horndean, is having a 24-hour BioBlitz event.
Tim Speller, the manager of the park, said: ‘The aim is to introduce visitors to the vast biodiversity within the park.
‘Over 24 hours we try to find as many species and record them with help from staff from the Biodiversity Information Centre.
‘Last year we made over 1,000 records covering 780 different species including some never before found in the park.’
The largest was the fallow deer and the smallest could not be seen by the naked eye.
There will be plenty for families to do, including encounter tables, pond dipping and a series of walks and talks.
And if you are prepared to go to bed late and get up early you can catch the midnight wildlife walk on Saturday and the dawn chorus walk at 4.30am on Sunday.
The fun begins at 4pm on Saturday.
