Our goal is the restoration of biodiversity, and our solutions are based around maximising the potential to reach this goal.
With over one million barriers in European rivers, there is a need to prioritise the dams that are removed. Our approach considers projects that:
- Maximise the potential for ecological gain.
- Are highly viable and can be implemented over short timescales. For example, it is estimated that over 100,000 barriers in Europe have been left abandoned and are not in use. These barriers are likely to be the most socially acceptable to remove.
- Offer value for money: it is estimated that 68% of barriers in Europe are less than two metres in height and it is primarily the small culverts, fords and weirs that cause the most fragmentation, not the smaller number of large dams. Fortunately, the small barriers are also the cheapest to remove.
- Removals in areas of comparatively low fragmentation: it will usually be more costly to achieve ecological restoration in highly fragmented areas.
