Sustainable restoration of the natural environment
An increasing focus on climate changes, depletion of natural resources and pollution has given sustainability a high priority on the environmental agenda. Also at ALECTIA. A large number of our projects integrate sustainability in relation to people, water, climate and the environment.
In 2008, we have participated in a large project concerning a watercourse rehabilitation of Gram Stream in Jutland for the Danish Forest and Nature Agency. The aim of the restoration is to prevent the extinction of the houting, a species of salmon. The houting is one of EU’s most threatened fish species that today lives only in the Danish part of the Wadden Sea area. The houting has been protected under an unconditional preservation order since 1983.
The project includes a series of activities, all aiming to improve growth and spawning conditions for the houting. Among other things, ALECTIA’s biologists have started a project to restore the original natural conditions in Fole Fish Farm and Gram Castle Lake. The present weir at Fole Fish Farm and the fall at the floodgates downstream of the lake have to be changed to restore the original watercourse and create free passage for fauna to the other parts of Gram Stream.
The present conditions basically constitute a total block for the migrating salmon fish on their way to the spawning areas. The river restoration gives the fish access to an extra 130 kilometres of stream. Furthermore, areas designed to provide optimal growth conditions for the fry will be established alongside the stream.
