I have been using two old drain pipes for years as storage for canes and poles so they have been upright and apart from the odd snail nothing has been in them. I have decided that laying down in my wild bit they may benefit a little creature as a nest or hibernating place but I need some advice as to how to make them more attractive and predator proof. I have piles of leaves and wood that I can either put in them or around them. They are approx 1 metre long and 25 cm wide (3ft by 10ins approx for us oldies) and open ended. Very heavy - made of concrete.
I have placed them under one of my oak trees (excuse the burnt wood art piece. It was rescued from the bonfire when I thought it had potential -
I'm sure something would like to use them but haven't a clue really.
