Between 21 and 23 June, technicians from FGN and UVEG returned to the field work in the wetlands of Castilla y León. This is the third visit to characterise the pilot wetlands and select the corresponding work plots. During this visit, the extraction of bio-indicators and diagnosis in the working wetlands has also continued, in relation to carbon fixation with respect to their current state of conservation and management methods. This work is part of the project’s field and measurement activities.
In Castilla y León, during these days, the experimental plots dedicated to mowing marsh vegetation once again took centre stage. In both the La Nava and Boada lakes, work was carried out in the areas defined as control plots and experimental plots. On this occasion, the vegetation was found to be very overgrown because the spring growth and flowering period had passed, and it was possible to compare that the vegetation in the areas not mowed on the previous day of field work was taller and more vigorous than in the project’s mowing plots, where the marsh vegetation had grown but in smaller quantities. The latter have been mowed manually for the second time, thus continuing the work of the comparative study of the project.
In Castilla-La Mancha, where there are two experimental areas for mowing, it was necessary to mow again because the vegetation growth, although not as vigorous as in the control plots, reached the same size as in the control plots. A curious detail was to note the presence of the plant known as castañuela (Cyperus rotundus), a perennial herb related to the plant used to make horchata. At an ecological level its presence is interesting because when selecting both mowing areas, the plant was not present. This gives indications that a controlled mowing could increase the plant diversity of the area, although it is still too early to say for sure, at least in the framework of this project.
Following this work, the monitoring of these actions continues, and the aim is to give them continuity over the next few months of the project.
