Impacts of Fenland restoration

FENFLUX: Eddy covariance fluxes in Fenlands

FENFLUX is a project run by the Department of Geography, University of Leicester (UoL) and the Centre of Ecology and Hydrology (CEH) in Wallingford in Wicken Fen. UoL runs a flux site in Baker's Fen, an area that is under restoration management since 1999after arable agriculture and CEH runs a flux site in Sedge Fen, an ancient Fen.

The aims of FENFLUX are to:

Fire chronosequences

FFID: Spatio-temporal characterisation of boreal forest fire intensify dynamics and its impact on carbon fluxes

NERC (UK Natural Environment Research Council ) PI: Prof. Martin Wooster, King’s College London, CO – Is: Dr. Heiko Balzter, NERC Centre for Ecology and Hydrology (CEH), Dr. France Gerard (CEH), Dr. Jörg Kaduk (University of Leicester).

The project aims to improve the understanding of spatio-temporal patterns and dynamics of boreal fire intensity and extent, the driving factors behind these variations, and the consequences for C fluxes.
