This week's Picture of the Week comes from Karen Auty. It is of two fisherman at dusk catching American crayfish in Yeadon tarn.

Karen said: "I enjoy photography and I love the outdoors and water. I am very fond of Wharfedale and some of my ancestors originate from the area from many generations ago.

"American crayfish (which is not native to this country, being introduced in the 1960s) have nearly eradicated the English species which is why the conservationists and fisherman try to catch them."

Karen was recently a volunteer 'Tourmaker' for the Tour de France.
