A SCIENTIST will lead a walk to look at research locations in a nature reserve.

John Adamson, from the Centre for Ecology and Hydrology, is leading a walk at Moor House Upper Teesdale National Nature Reserve, near Barnard Castle. Walkers will visit the automatic weather station and river gauging station.

The walk, which is free, is two miles, but is graded moderate because some sections are over rough or boggy ground.

The walk starts at 1.30pm on Sunday, July 22, and finishes at 5.30pm. Meet at Garrigill, outside the post office, where a minibus will take walkers to the reserve.

Numbers are limited, so booking is essential.
