LakeBESS start-up

Lakes are inspirational places for people enjoying outdoor activities and they are cherished by local communities and holiday-makers alike. However, lake ecosystems are threatened by environmental change and loss of biodiversity that can have cascading and catastrophic effects.

The LakeBESS project, run from the Environmental Change Research Centre (ECRC) at UCL, is focussed on two lake districts, the Broads in East Anglia and the Upper Lough Erne district in Northern Ireland.

debarcadaireWe are looking into how biodiversity regulates ecological balance within lakes and would like to assess the consequences of biodiversity loss for the provision of ecosystem services. Ecosystem services from lakes are extremely diverse: recreation, tourism, water purification, flood prevention, provision of fish for anglers and fisheries and other supporting services such as carbon storage for climate mitigation.

Because of this variety, changes in lake ecological functioning may affect the different services in different ways, rendering best practices for restoration and management difficult to establish.

One aspect we are particularly interested to develop in LakeBESS is the importance of ecological connectivity between lakes for their biodiversity. Connectivity may be a major factor determining lake ecosystem resilience because it counter-balances the negative effect of local extinction by increasing species re-colonisation.

Another aspect of interest is the consequences of biological invasions by organisms such as zebra mussel and Canadian pondweed.

We have just started this project as part of the Biodiveristy, Ecosystem Services and Sustainablility (BESS) research programme funded by the UK Natural Environment Research Council (NERC).

Our team is composed of Carl Sayer, Helen Bennion, Jorge Salgado and Ambroise Baker at UCL, Tom Davidson at the University of Aarhus (Denmark), Beth Okamura at the Natural History Museum and Nigel Willby at Stirling University. We are looking forward to a field campaign this summer and to presenting the result of our work to the numerous stakeholders in both lake districts.

We also would love to hear your take on how changes in lakes, or in a particular lake, can affect people’s lives.
