i have today contacted the r.s.p.c.a / defra and seascape according to them it is not illeagal to move tadpoles from private ponds in fact seascape said it is better for them. it becomes a problem if you try and remove them from public ponds / streams / and rivers as these can have some restrictions depending where you are located and can carry a risk of contamination. i hope this is a help to you and thanks to all the people that got back to me cheers terry
