Abstract
Cacti inhabit a wide diversity of climatic regions and ecosystems. Like many other plants, cacti populations are seriously threatened by habitat destruction and other human activities such as illegal collecting. This chapter examines the biodiversity of both wild and cultivated cacti, and discusses contemporary and long-term issues pertaining to conservation of cacti. It first describes the factors affecting biodiversity of cacti and the estimation of genetic diversity in wild and cultivated cacti, and then discusses the effects of habitat destruction and collection on biodiversity loss of wild cacti. International activities that encourage the conservation of cacti are also presented.
