Ideal Pokestop rejected twice. Any suggestions appreciated.

I have submitted this twice now and it's been rejected both times. It is an interesting place, in a park area away from the road with easy pedestrian access.
Could you please let me know why this is being rejected? It's a great spot for a stop.

So those are boxes placed so the bat population can stabilizy and grow, and then you want to mark them as a special point that people go to play mobile games around?
Wouldn't that disrupt with the goal of those boxes?
Bat houses simply don't meet the eligibility criteria on their own.
Bat boxes and bird boxes are generally considered to be mass produced objects that don't meet criteria. If they had an educational sign nearby that explained why they were there and provided info on the various kinds of bats we have in the UK, then that would be eligible, but the boxes themselves are not.
So unfortunately there's not really anything you can do to change the outcome for this nomination. Though for what it's worth, I think bats are adorable and would be fascinated watching them come and go from these boxes.
Which Niantic criteria do they meet? I don't see these as a great place to be social, to explore or to get fit. "1* - Does not meet criteria" rejection for me.
As @WheelTrekker-ING and @HankWolfman-PGO said, nominating bat boxes or bird boxes are likely to interfere with the purpose of these boxes, which is to provide safe places to birds and bats, not providing packs of gamers a place to chat and meet.
Otherwise, if there is any educational sign around about these boxes, it can be great nominations.
Have a happy game, and happy life to the bats !
Something like that needs an information and educational board to explain what it is for.
Thanks all! I'm new to nominating stops, so did not realise that this would not be suitable.
These are the only bat boxes in our town, so had no idea they were seen as mass produced items.
As the tree is off the path, and the boxes are high up, there's no real risk of the bats being disturbed. The area is a popular play spot and dog walking location already.
The tree being off the path could have hurt it too. You're supposed to ne able to walk up and touch the object. If there's a mass of brambles between the path and the tree, some reviewers might have voted no pedestrian access.
The park or whatever group installed the bat boxes might be willing to put up a sign. It would be cool to have an educational sign about the bats and conservation efforts.
