Commitment to Nature

As part of our commitment to best practice and mindful of the rich natural heritage surrounding the quarry in Cong, Co Mayo McGrath Limestone in conjunction with Earth Science Partnership Consulting Engineers have set aside areas within the quarry boundary for nature conservation. A base-line assessment of the ecological resources of these areas has been carried out, in order to manage them in a manner that will optimise their value for nature.

Several mammals and birds protected under the EU Habitats Directive 92/43/EEC and Birds Directive 79/409/EEC (amended 2009/147/EC), are active in the locality of the quarry including: the lesser horseshoe bat, red squirrel, pine marten, the Irish hare and otter. The secluded conservation areas safeguard their continued presence by providing corridors for shelter, passage and forage. Composed of semi-natural woodland, scrub and grasslands, the main conservation area is nestled between the quarry and the ‘Dry Canal’.

Seasonal flooding of this area enhances biological diversity, by increasing the presence of aquatic invertebrate life. The quarry and surrounding corridor also supports a diverse number of wild birds including several species of finches, tits and warblers, further making the quarry an attractive site for peregrine falcon, which regularly nest on the steep quarry faces.

Biodiversity Training Plan

A Training Plan to safeguard the existing Biological Diversity within the quarry (click here to view) has been adopted. This helps native and protected plants and animals present in the quarry to come to the attention of staff. By increasing awareness, potential impacts from quarrying operations can be detected at an early stage and mitigation measures put in place. These include procedures such as seasonally excluded extraction areas, provision of buffer zones and alternative habitat formation.

Detailed Landscaping and restoration plans has been put in place to encourage the use of native plant species and are designed to link in with the existing natural habitats. The training plan also brings potentially invasive plant and animal species to the attention of staff. These have the potential to out-compete native flora and fauna and threaten their continued existence in the quarry.

Knowledge of their location and extent in the quarry enables early control measures to be put in place and avoids them getting a foothold in the locality.

The provision of an ecological assessment in conjunction with a landscaping and restoration plan and a biodiversity training plan for the quarry ensures that a holistic approach to the environment is taken by McGraths Limestone.
