Artificial Refugia
(slrpnk.net)
If this isn't the most dystopian thing you've read today I don't know what is.
Artificial Refugia (such as bat boxes) can be used to somewhat offset lost habitat, but it's like replacing a rainforest with a plastic plant and calling it conservation. Further, unless they are meticulously designed, they can act as traps (trap animals inside), snack plates for predators, or even 'cook' the animals inside them.
Not all are used for these habitats, most are sold to the public to support charities and the rest are recycled into children's playgrounds or similar.
This is also why the spectators are not allowed to keep balls that they catch unlike other tennis tournaments. It's not to be mean. Wimbledon tennis balls have a life after the tournament.
