A BioBlitz will take place at The Raggatt next weekend.
The event is a challenge to see how many different types of wildlife can be found in the area in 24 hours.
Wildlife specialists will be sharing their enthusiasm for finding and naming wildlife with families and anyone who wants to join in.
The free event will take place on Sunday, August 28 or the 29th if very wet.
The Raggatt is just south of Glenfaba Bridge on the road south from Peel to Patrick.
The night before there will be a Manx Bat Group bat walk to see how many different bats can be found at the site, starting at 8.30pm. Ring Richard Selman on 450076 for details.
Government biodiversity officer Liz Charter said about the BioBlitz: "During the day participants will search the river banks, fossick among the bushes, turn over stones, dabble in pools and peer into crevices, through binoculars and down microscopes to see what magnificent and mysterious biodiversity lurks at the Raggatt, among the trees, along the river and in the marsh, pools and banks by the Heritage Trail.
"The more eyes and ears the better. Come and join us!"
During the day there will be a programme of activities, starting with seeing and hearing the local birds at 9am, opening a moth trap at 9.30am and various bug, butterfly and mini-beast explorations during the day.
In the afternoon the diverse plant life and flowers will be 'blitzed'.
The event finishes with a chance to see 'fishing with a difference' in the Neb, with the Department of Environment, Food and Agriculture fisheries team demonstrating electro-fishing.
For further information on the day's programme see the DEFA website - www.gov.im/defa -or ring Liz Charter on 450078.
There will be light refreshments available to buy in the base camp marquee. Participants can park at the Royal Show field, Knockaloe, which is kindly being made available by the Royal Manx Agricultural Show.
The event is organised by DEFA and the Manx Wildlife Trust, is sponsored by Colas and is taking place with the kind permission of the land owner.
