This week from the Ecology team is our principal ecologist Dr. Luis Gustavo Iemma BSc, MSc, Ph. D, CEcol MCIEEM Iemma and his favourite species, the Brown Long-eared Bat.

Brown long-eared bats (Plecotus auritus) hold significant ecological importance in Ireland. As they contribute to the control of insect populations, making them an essential part of Ireland’s ecosystem. During construction projects, it’s critical to be mindful of brown long-eared bats, as they frequently utilise buildings, trees, and other structures as roosting sites. Safeguarding their habitats and roosting areas is paramount during construction to protect this species. Brown long-eared bats typically reside in a variety of habitats, including woodlands, hedgerows, and wetlands, where they often roost in trees or buildings. Conservation efforts aimed at preserving their habitats are essential to ensure the continued presence of brown long-eared bats in Ireland’s rich biodiversity.

Our team of ecologists conduct a diverse array of bat surveys, including transects, emergence/re-entry, and preliminary roost assessment, supported by thorough data analyses. We use a range of specialised equipment, including thermal cameras, endoscopes, and both static and active detectors, to ensure that our results are as thorough and accurate as possible.
