Newt egg strips

My first attemp at making newt egg strips. All you need is a black rubbish bag, some sticks and stones.  The bag is shredded into strips, weighted down with stones, then fixed in the bottom of a pond with a cane or stick. Full instructions can be found here.
Newts lay their eggs on the leaves of submerged plants, folding the leaf over the egg to protect it. The idea is that the plastic strips plays the same role of the leaf - in fact it is more pliable so easier for the newts to use. It also makes it easier for the surveyor at a later day, because if newts are present in the pond they are likely to have laid eggs on the strips, which are faster to find than searching through the vegetation.
Hopefully I will get permission to deploy some of these in my survey ponds, and we can see if they work. This is still an experimental process in it's infancy, so it would be good to get some positive results.
