Is an additional stone necessary? Artificial refuges do not always attract snakes

The Takeaway
Conservationists all over the world build artificial stone piles to give declining snake populations a place to hide and breed. However, a new study in the Mediterranean found that snakes often ignore these 'luxury condos' entirely. It turns out that what looks like a perfect home to a human is often unappealing to the animals we’re trying to save. This suggests we’ve been spending decades of resources on a strategy based on a total misunderstanding of animal behavior. We need to stop assuming we know what wildlife wants and start looking at the data, or we’ll keep failing to save them. Good intentions don't always lead to good conservation.
From the abstract
Although artificial refuges are widely used to improve or restore natural habitats, their effectiveness is rarely evaluated. Snakes depend heavily on the availability of refuges and are in sharp decline worldwide. Amending their habitats by creating refuges is therefore a widely used but undervalued solution. In a heterogeneous Mediterranean habitat, we installed four clusters of five artificial refuges (ARs) in the form of semi-buried stone piles, and deployed a network of 400 fibrocement board
