 The willingness of many anoles of living close to humans in heavily altered habitats have made them common.Some anoles can occur in very high densities, as illustrated by the Saint Vincent bush, Puerto Rican bush and spotted anoles where it has been estimated that there locally are almost 28,000 individuals per hectare (11,500 per acre) in the first species and at least 20,000–21,000 per hectare (8,000–8,500 per acre) in the last two.However, in most species the density is lower and in rare anoles it is can be well below 100 individuals per hectare (40 per acre).
