Background information and definitions
Modifying caves may alter the internal microclimate and make conditions unsuitable for roosting bats. It is important that the microclimate is maintained following any modification. Restoring the microclimate of altered caves may also encourage cave-dwelling bats to return to abandoned roosts.
For a similar intervention, see ‘Threat: Energy production and mining – Mining – Maintain microclimate in closed/abandoned mines.’ See also ‘Install and maintain cave gates to restrict public access’ for one study in which a stone wall and gate influenced the microclimate of a cave with an effect on hibernating bats.
