Appenzell vs Savannah

Informations

Appenzell is a historic canton in the northeast of Switzerland, and entirely surrounded by the canton of St. Gallen. Appenzell became independent of the Abbey of Saint Gall in 1403 and entered a league with the Old Swiss Confederacy in 1411, becoming a full member in 1513. It has been divided since into Appenzell Innerrhoden and Appenzell Ausserrhoden since 1597 as a result of the Swiss Reformation.

The territory of Appenzell as a geographical entity is known as Appenzellerland while in political contexts, the two cantons (until 1999 half-cantons) are referred to as beide Appenzell ("both Appenzells").

Informations

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.

Similarly Guinean savanna has 129 trees/ha, compared to 103 for riparian forest, while Eastern Australian sclerophyll forests have average tree densities of approximately 100 per hectare, comparable to savannas in the same region.Savannas are also characterised by seasonal water availability, with the majority of rainfall confined to one season; they are associated with several types of biomes, and are frequently in a transitional zone between forest and desert or grassland. Savanna covers approximately 20% of the Earth's land area.
