A savanna or savannah is a mixed woodland-grassland ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses.Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in forests. The South American savanna types cerrado sensu stricto and cerrado dense typically have densities of trees similar to or higher than that found in South American tropical forests, with savanna ranging from 800–3300 trees per hectare (trees/ha) and adjacent forests with 800–2000 trees/ha.

One of the oldest French cities, it has been known by Greeks as the capital of the Arvernie Tribe before developping under the Gallo-Roman era under the name of Augustonemetum in the 1st century BC. The forum of the Roman city was located on the top of the Clermont mound, on the site of the present cathedral. The High Middle Ages were marked by the looting it was subjected to by the peoples who invaded Gaul and would not have been spared by the Vikings during the weakening of the Carolingian Empire.
