Improvement of hydrological conditions for naturally regenerating raised bogs in Engbertsdijksvenen

AddMire LIFE will tackle the desiccation of degraded raised bogs still capable of natural regeneration and active raised bogs in Engbertsdijksvenen, within the context of a major raised bog restoration effort. It aims to improve the hydrology of the project area to favour regeneration of 618 ha of degraded raised bogs, by creating bunded cells to catch and retain surplus precipitation and keep the water level more stable. Permanent wet conditions are beneficial for the regeneration of degraded active bogs and enhancing the quality of active bogs. TheAddMire LIFE team will also draft and promote a best practice manual on raised bog restoration and increase public awareness about the importance, value and opportunities of raised bog habitats.
The project will contribute to climate change mitigation by conserving, restoring and improving the management of peatlands which helps reduce atmospheric greenhouse gas (GHG) concentrations substantially. It will contribute directly to the EUs 2030 climate and energy framework objective of cutting GHG emissions by 40% by 2030 compared with 1990 levels.
Expected results:
* Construction of 35 hydrologically isolated bunded cells. By the projects end, these will form a terraced mosaic landscape in which bog forming peat mosses can grow, creating an acrotelm;
* Production of a baseline, an interim and a final monitoring report. The project will also report on the impact on residents and stakeholders;
* An updated best practice manual on raised bog restoration for use in other projects and dissemination to experts;
* Inspiring other peatland managers to replicate the approach to multiply savings; and
* Raised water levels, recovering peat moss vegetation and lower nitrogen depositions are expected to halt further tree growth in Engbertsdijksveen in the long term.
