We put it back at the water's edge so it might still be there.
Also, the Autumn Crocus leaves have started into growth in the Park Nook Lock area of woodland to the west of the reserve. (Pics on Calderdale-wildlife.blogspot - two places about 475 metres apart I've re-discovered so far.) Whoever has started maintaining it is doing a good job of clearing up the plastic but I don't agree with pruning the low branches obstructing the path, as now the off-road cyclists are going through and cutting up the ground. It's more interesting as well as being better exercise for us walkers if we have branches to climb over and duck under.
