Despite their many differences in precipitation, temperature, plant and animal species, history, and dynamics, North American savannas share some important characteristics, especially the critical roles that fire plays in these ecosystems. In many regions there has been a great reduction in the extent of savanna vegetation since Europeans and Africans first arrived in North America just over 500 years ago, but what remains has supported a substantial body of research. This research has not only provided many insights into the processes that form and shape these savannas, but has also guided the management of the remaining tracts of savanna and many successful savanna restoration efforts. This chapter can only provide a brief overview of the many different kinds of North American savannas. After clarifying some definitions and briefly describing broad climatic patterns, four factors that affect almost all North American savannas are discussed separately: fire, grazing, biodiversity, and conservation. The remainder of the chapter is a brief tour of the savanna ecosystems of North America. This is organized by the dominant woody species, rather than by the region, of each type of savanna, to draw attention to the many similarities between, for example, the longleaf pine (Pinus palustris) savannas of northern Florida and the ponderosa pine (P. ponderosa) savannas of northern New Mexico 2300 km away (see Figure 5.2 for locations of states and provinces mentioned in this chapter).","PeriodicalId":299012,"journal":{"name":"Savanna Woody Plants and Large Herbivores","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115242138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
