How can technology help us detect beaver burrows in the wild and assess their associated risks to public and private interests?

Beavers are a protected species. However their burrowing sometimes causes us problems. Burrows have been associated with breaching of flood banking and water impoundments, undermining of infrastructure and collapse of sections of riverbank, impacting on businesses and livelihoods. Entrances to beaver burrows are usually dug below water, which can make detection difficult. A non-invasive method needs to be developed in order to both reliably detect potentially problematic burrows and assess the risk the burrow prese...
