Pioneer Vegetation
Native or exotic plants that first occupy open areas whose previous vegetation was suppressed or degraded (or even in natural clearings).
It is the flora that first occupies the physical-ecological space left by the suppression or degradation of native or exotic vegetation, carried out with or without authorization from the public authorities. In some cases, it also occupies inhospitable regions for other species, such as land that is too dry, poor in nutrients or is affected by erosion. At the same time, pioneer vegetation, intentionally cultivated or not, can favor the recovery of natural ecosystems by making the environments it initially occupies more favorable to the growth of native flora.
