Data analysis

Precipitation over the last 20 years has varied with an upward trend which coincides with another rise in temperatures, this causes more water to evaporate and as it circulates and has Sierra Nevada next to it, it rises and cools which produces precipitation. This precipitation will end up in the lagoon again, because the plates are below each other. This does not in itself affect the surface, as although there is more rainfall there is also more evaporation of water so it balances out, but it does affect the reed beds.

The surface area remained quite low while the peatland was allowed to be exploited until 2010, when measures were taken to preserve the lagoon, mainly because it was no longer profitable. The fact that it was no longer exploited also led to the cessation of water pumping, which led to a rapid increase in the surface area, which has stabilised over the years.

Lately the human impact has been both positive and negative. Firstly, positive, as for some years now a series of measures have been taken to preserve the conservation of the wetland, which has meant that since 2010 there has been a great diversity of species which, without these measures, would not be able to live. Secondly, it has been negatively affected by a series of factors: the existence of infrastructure very close to the wetland, such as a quarry that causes noise pollution that negatively affects certain species, like birds, and suspended dust that can end up dissolving in the water and contaminating the water. The road also causes water pollution, as the waste left by tyres on the asphalt ends up back in the wetland due to runoff.
