I just registered and joined this forum to ask exactly the same question! I thought I must be missing something. I run the UK Glow Worm Survey, and formerly I could simply click on a record square and discover numbers seen -- absolutely vital for the survey, where we are concerned with declining numbers.
The only way to find the data now seems to be to download the entire set of databases that could contain the data, which usually include all species rather that just the glow worms, and search each one for the grid reference shown on the map. Or am I still missing something?
The old version of the map now doesn't work, so I am concerned that a useful research tool has now been lost.
