The Sierra de la Mosca, the Mountain and the Calerizo de Cáceres constitute "a natural space of high
ecological value, a refuge for flora and fauna, being the only rugged enclave that stands out from the
Trujillo in the peninsula of Cáceres". It is a "green island in the middle of a cereal area". It is a shelter
for animals and natural corridor that connects the SPA of Los Llanos de Cáceres and Sierra de Fuentes
with the SPA of the capital, the only one in Europe located in a city by the abundance of the kestrel
primilla.This is one of the many reasons included in the report made by professionals and scientists
to support the request signed by 43 associations in June. Objective: to request the declaration of the
Sierra de la Mosca, the Mountain and the Calerizo as 'Protected Landscape', due to its “high geological,
prehistoric, archaeological and biological value, increased by the fact of being next to Cáceres and
Sierra de Fuentes”. The purpose is to shield these places against initiatives such as the lithium mine
in Valdeflores, which part of the public does not agree.
The request has been registered with the Regional Ministry of Environment. It is alleged that «the
Sierra de la Mosca constitutes an exceptionally well-preserved natural environment near Cáceres (...).
It is his lung, a natural regulator of temperatures in a city with long summers and little rain in these
months ».It is a "natural jewel" because of the diversity of flora that gives it its conservation status,
and because many species use this place "as the last stronghold to survive in the face of a changing
socio-environmental landscape." And the geomorphological, climatic, landscape and water
characteristics of this space, all make it «an oasis of biodiversity».
The predominant habitat is the Mediterranean forest and scrubland, which has the best representation
of plants and animals linked to it thanks to the fact that the area has been poorly manipulated. But
the mountains accommodate another multitude of microhabitats, which make it special when it comes
to housing a large number of species vitally linked to these spaces: amphibians, reptiles, birds and
mammals; in many cases protected by their exceptional nature.
