Realities of bat conservation in Malta

As a wildlife conservationist with an especial interest in bats, I sometimes despair of the state of conservation in Britain and the prospects for the future of biodiversity. Cut-backs in conservation spending, prioritisation of projects that engage people, rather than those with real impact, the near-impossible task of enforcing wildlife law are all sources of frustration. Whilst these problems are all very real, they were put in context for me last year, when I spent some time working with bats on the Maltese Islands.

Malta is of course, part of the European Union and therefore bats and their roosts have the same legal protection, as elsewhere in Europe. However, Malta is a small country and pressures on wildlife are magnified by problems of scale, as well as by social issues.

I was lucky enough to spend time with Dr. John Borg, Director of the Malta Natural History Museum in Mdina. John is an energetic and ornithologist and bat-worker, who faces monumental difficulties and yet still works relentlessly to promote conservation. Malta, like several other Mediterranean islands, has a strong culture of shooting and trapping migratory birds. Though now curbed by European legislation, this is still a very real problem in Malta and it affects bats too, as they are used for target practice as they emerge from the roosts at sunset.

When I was there the sound of gunfire was a constant backdrop, away from the towns. Hunters take their shooting heritage very seriously and John's work as a bird-ringer has brought him into conflict with them. Whatever our problems in the UK, we don't face the kind of intimidation John faces. He has had his car set alight, his tyres slashed and lights smashed and has even had a hole punched in the driver's door by a shotgun blast! To emphasise the point, when we were leaving a bat cave we had to leave quickly, as the trees above our heads were shredded by apparently deliberate shotgun fire.

The small size of the islands and their growing population creates massive development pressure, and the Maltese Environmental Protection Agency (MEPA) are very active in enforcing the law. Nonetheless, bat roosts are heavily pressured, especially underground sites, as the size of the islands makes the limestone caves used by Maghrebian Mouse-eared Bats (Myotis punicus), Grey Long-eared bats (Plecotus auritus) and Lesser Horseshoe Bats (Hipposideros hipposideros) often well-known and threatened by human activity.

I visited two of the biggest maternity colonies of Maghrebian Mouse-eareds, neither of which showed any signs of being used by the species any longer. Ghar Hasan is an extensive cave on the cliffs at the south east coast of Malta. It is a popular attraction and, as well as being visited by tourists, the litter within showed it is also used by the seedier end of humanity. In order to protect the bat colony, John Borg paid for a gate to be installed on the section of the cave used by the bats. When we visited part of the gate had been ripped away. John showed me where, in previous years there had been a large heap of bat droppings. Now there is nothing.

Another formerly prolific maternity cave was Ghar il-Friefet, on the outskirts of the town of Birzebugga. When a new road was built over the cave attempts were made to safeguard the bats by gating it. Today this gate lies alongside a hairdresser's salon and the cave is no longer used by bats. The road surface was less than three metres above the cave roof and John described how the bats would take flight every time a truck drove overhead.

I wouldn't want to leave you with the impression that wildlife conservation is a lost cause in Malta. Alongside John's efforts, Birdlife Malta are an extremely active conservation organisation, who are making a real impact. Also, MEPA have a deliciously hands-on approach to dealing with planning violations (often the hands are on the controls of a bulldozer), from which our SNCOs and local authorities could learn a lot.

One of the most poignant moments of my visit to the island was when I spent some time with a group of undergraduates at the University of Malta, teaching them how to use bat detectors. Their enthusiasm and commitment to wildlife conservation was little short of inspiring and if they are the future of Maltese wildlife conservation the game ain't over yet.
