Wildlife enthusiasts are needed to help track down the wonderfully different species that live at Fort Nelson.
During the Bio-Blitz event, taking place tomorrow and Sunday, visitors to the fort will be able to use their investigation skills to locate plants, insects and animals that call the historic venue home.
You will be able to go on a wildlife discovery tour in areas of the site that are normally out of bounds to the public and find out just how Fort Nelson was transformed from a bramble patch into a national museum.
There will be a range of wild craft activities for children to test their creative skills with.
You will be able to see birds of prey up close (Sunday only) and if you bring along your camera you can have a go at wildlife photography and land art.
This family attraction is open to everyone. It takes place tomorrow and Sunday, from 10am until 5pm daily.
Admission is £3 for adults and £2 for children.
