Name:
Cerrado Savanna Macrogroup
Reference:
NatureServe Biotics 2019
Description:
The macrogroup includes the different types of savannas of the Cerrado biogeographic region in Brazil and Bolivia, which are distributed in the extensive plateau of the Brazilian Shield that covers a significant portion of central Brazil south of the Amazon Basin and extends to the southeastern corner of Bolivia. The nutrient-poor soils to which these savannas are associated include quartzitic sands, sandstones, and gravels that are the product of the weathering of the laterite deposits that formed on top of the ancient rocks of the shield. The elevation ranges between 400 and 1700 m, the climate is tropical seasonal and total precipitation amounts are between 1200 and 2000 mm. The savanna types cover a wide range of physiognomies from open grasslands to a densely treed savanna locally called "cerrado." To some extent these savanna types are related to nutrient and moisture availability, but fire succession dynamics also play a role in the distribution of these types at any given time. These are the most extensive savannas in South America and also the most diverse and endemic in floristic composition. Among grass/herb genera, <i>Burmannia, Rhynchospora, Drosera, Cipura, Digitaria, Sisyrinchium, Utricularia, Cuphea, Cleistes, Habenaria, Sarcoglottis, Aristida, Axonopus, Panicum, Mesosetum, Paspalum, Trachypogon</i>, and <i>Imperata</i> are common. Diagnostic cerrado woody species are <i>Qualea parviflora, Qualea grandiflora, Qualea multiflora, Kielmeyera coriacea, Byrsonima coccolobifolia, Byrsonima verbasifolia, Bowdichia virgilioides, Curatella americana, Connarus suberosus, Caryocar brasiliense, Astronium fraxinifolium, Annona crassiflora, Brosimum gaudichaudii, Acosmium dasycarpum, Hymenaea stigonocarpa, Erythroxylum suberosum, Hancornia speciosa, Lafoensia pacari, Machaerium acutifolium, Pouteria ramiflora, Roupala montana, Tabebuia aurea, Tabebuia ochracea, Couepia grandiflora, Terminalia brasiliensis, Rourea induta, Diospyros hispida, Byrsonima crassa, Anacardium occidentale, Vochysia elliptica, Vatairea macrocarpa, Terminalia argentea, Sclerolobium aureum, Syagrus comosa, Vochysia rufa</i>, among many others.
