First w4c mowing in La Nava lagoon

Last August 2021, field work returned to the La Nava lagoon (Palencia), on this occasion to begin the W4C conservation actions, specifically the first scheduled mowings. This work is part of the field and measurement actions of the LIFE Wetlands for Climate project.

Mowing is an effective method of controlling excess helophytic vegetation in wetlands, and basically consists of cutting and removing the aerial part of this vegetation. If this work were not carried out, the vegetation would be favoured, leading to an accumulation of plant debris in the wetland bed. This leads to an excess of nutrients and ultimately to a process of eutrophication of the wetlands, resulting in the loss of water quality and biodiversity in these ecosystems.

The mowing was carried out in the conservation area of the La Nava lagoon. A total of 5.2 hectares have been mown, from which 21 bundles or alpacas have been obtained, totalling a total weight of 7,350 kilograms, which will be used for fodder and bedding for livestock, specifically for beef cows from a local livestock farm located in the nearby town of Villatoquite.

This action is of great importance for the conservation of the wetland, allowing the regeneration of submerged aquatic flora, which is very important as the basis of the trophic chain in wetlands. These harvests will also be used to monitor the project over the next few months.
