Empty forest

A portion of the forest where, although still possible to observe the green of the forest, the presence of animals – especially pollinators – is already rare or null, compromising the region’s environmental services and the long-term survival of the forest.

The more fragmented a forest is, the more empty it is – that is, the less biodiversity it harbors and, therefore, the more endangered it is.
