Blessington Lake is an artificial lake created in the 1940's to provide drinking water for the city of Dublin and also to provide water for a dam to generate electricity.

Over the last 70 years, it's become very much a part of the landscape in County Wicklow, and it has developed its own population of wildlife in the process!

Our reporter, Terry Flanagan, took a tour of Blessington Lake to find out more...

This weekend, a new tour boat will begin to take tours out on the lake and explain what is found under the water.

A large number of farms were flooded to create this lake. The lake is huge (a coastline of nearly 60 km) and it is a lovely day out.

Lots of wildlife including ospreys - very seldom seen in Ireland - other birds of prey, ducks, geese and lots more!

He loves his birds and more specifically the partridge but he is also responsible for the radical increase in lapwings, which were in rapid decline not only in Ireland but in Europe... Kieran Buckley, of the Irish Grey Partridge Conservation Trust & Peatland Habitat, is in studio to explain more!

Every Friday, 'Mooney' concentrates on wildlife and nature. So much so, that the Friday programme has a special name: 'Mooney Goes Wild'. We regularly hear of interesting and exciting stories about foxes, pine martens, and the birds and the bees. But, have you ever stopped to think of the wildlife that exists WITHIN the human body?

It’s estimated that there are somewhere between 6 and ten billion cells making up the average full grown human body. That is, up to 10,000,000,000 cells. Well, for every one of those cells, it’s estimated that there are more than 10 microbes in or on our body surface. That’s an astonishing 100,000,000,000 bacteria, fungi or viruses associated with each of us. Not such a nice thought, is it?
