Hannah works as a Research Ecologist, analysing quantitative data from a range of projects across Wales.

Interests & Responsibilities

Hannah is interested in combining traditional and novel monitoring techniques to better understand species’ behaviours and ecology (at a variety of scales, from individual through to community level), especially in light of changes in their environments (be it human induced or natural), in order to aid conservation efforts if appropriate.

She completed her PhD at Cardiff University, where she assessed the conservation biology of two species of seabird that breed on the same islet, but at different times of year. This included developing a bespoke Raspberry Pi based camera system to gain a snapshot of behaviours and potential threats in nests.

Prior to her PhD Hannah has studied a wide range of different species across a variety of habitats. These have ranged from tropical coral reef fish behaviours to interactions between a temperate reef seaweed and a limpet that almost exclusively relies on it to survive, to monitoring migrating waders and migrating and breeding passerines (including Swallows).

Hannah is based within the BTO Cymru office looking at Welsh bird populations and their conservation.
