BDMLR is a voluntary network of trained marine mammal medics who respond to call outs from the general public, HM Coastguard, Police, RSPCA and SSPCA and are the only marine animal rescue organisation operating across England, Wales and Scotland. Not only are they called upon by the other emergency services, but they also train their staff.

BDMLR is a registered charity and is operated entirely by volunteers. Their rescue teams are on call 24 hours a day, 365 days a year.
