Bog Rehabilitation

Peatland rehabilitation

The key objective of peatland rehabilitation is environmental stabilisation. This involves stabilising the bare peat surfaces, slowing water movement across the cutaway and trapping mobile silt.

Enhanced rehabilitation

Enhanced rehabilitation measures will deliver more substantial ecosystem service benefits and will bring accelerated and enhanced environmental stabilisation. The objective of these enhanced rehabilitation actions is to optimise suitable baseline hydrological conditions for climate action benefits, to slow the movement of water across these landscapes, and accelerate environmental stabilisation via natural colonisation. This means rewetting peat with the most optimum water levels for the development of vegetation that suits the underlying environmental conditions, setting these areas in a direction towards naturally functioning wetland and peatland habitats.

Enhanced rehabilitation measures

Enhanced rehabilitation measures include blocking production field drains with peat drain blocks alongside more intensive measures such as the creation of low bunds to hold water, re-profiling of peat fields to maintain optimal hydrological conditions and potentially seeding or introducing natural vegetation. These measures will allow for more uniform coverage of water at an ideal depth for vegetation colonisation and in particular the development of mosses.

Varying conditions

Different rehabilitation methodologies will be applied due to different cutaway environments and underlying ground conditions. In general, there is ‘no one size fits all,’ as each cutaway bog will have different rehabilitation challenges. The overarching and guiding principle for the enhanced rehabilitation measures will be tailored on an individual bog basis – integrating the most suitable objectives, interventions and targets with different environments and environmental conditions so as to optimise ecosystem service benefits.

Investigations

Measures to seek to improve environmental conditions through rewetting will be guided by site investigation and will take account of each bog’s conditions. The measures will target those areas where maximum climate action and other benefits can be developed and where embryonic peat-forming habitats could potentially be developed.

Monitoring

Monitoring shall be carried out to determine that predefined targets have been reached and that will allow an analysis of costs and benefits of each approach. These predefined targets include a reduction in bare peat cover and establishment of suitable habitats, including Sphagnum-rich vegetation, creation of suitable water conditions, reduction in greenhouse gas emissions, and improvements in water quality.
