groves of gorse are often set alight by arsonists in dry summers producing a blaze that can be seen for many miles around. Whilst this may benefit the gorse and the ecosystem-based around gorse, the fires often spread into other areas of established woods where considerable damage is caused. These fires can also threaten gardens and outbuildings lining the base of the hill. Bangor Mountain provides the main southern watershed for the River Adda, the principal river flowing through Bangor. However, as the river has now been culverted throughout its whole length in the built-up area of the city, it is little known to the city's population. Part of Bangor Mountain was removed to provide car parking for a new discount supermarket. As a result, the footpath in this area now approaches very close to a precipitous edge protected by two-metre-high railings topped with sawtooth edging. The placement of the car park has occasionally led to vandals damaging parked cars utilising throwing rubble down from the footpath.
