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.

Carlisle ( kar-LYLE, locally KAR-lyle; from Cumbric: Caer Luel; Scottish Gaelic: Cathair Luail) is a border city and the county town of Cumbria as well as the administrative centre of the City of Carlisle district in North West England. Carlisle is located at the confluence of the rivers Eden, Caldew and Petteril, 10 miles (16 km) south of the Scottish border. Originally in the historic county of Cumberland, it is now the largest settlement in the county of Cumbria, and serves as the administrative centre for both Carlisle City Council and Cumbria County Council. At the time of the 2001 census, the population of Carlisle was 71,773, with 100,734 living in the wider city. Ten years later, at the 2011 census, the city's population had risen to 75,306, with 107,524 in the wider city.The early history of Carlisle is marked by its status as a Roman settlement, established to serve the forts on Hadrian's Wall. During the Middle Ages, because of its proximity to the Kingdom of Scotland, Carlisle became an important military stronghold; Carlisle Castle, still relatively intact, was built in 1092 by William Rufus, and once served as a prison for Mary, Queen of Scots in 1568.
