Engineered Restoration Techniques for Active Degraded Raised Bogs

Restoration of degraded active raised bog has to date focused on rebuilding the fragile remnants’ of original ecosystems by manipulating and restoring ecosystem structure, management of hydrology and biodiversity with a view to developing and sustaining the characteristic functions required for the transition to a pristine, fully functional raised bog. To achieve the principles outlined requires the development of a management plan that embraces the hydrological regime, biogeochemical cycling, macro and micro topography combined with monitoring and analysis of data over a prolonged number of decades. The fundamental problem with most restoration strategies is lack of, or, rapid depletion of water supply to the area of bog that is actively regenerating, thereby accelerating the rate of peat oxidation, adverse chemical transformations and subsequent subsidence of the peat mass.
The hypothesis that sustainable benefits accrue from deployment of engineered renewable technologies to rehydrate the bog, thereby favouring autogenic plant succession, decomposition and peat formation; expansion of a geo-hydrochemistry profile typical of the original ecosystem and subsequent development of a comprehensive conservation management plan.
