This guide will use the EPAâs definition of sustainability, and will emphasize the environmental dimensions of sustainability plans. Other uses of the term âsustainability planâ may emphasize financial sustainability rather than environmental sustainability. [1]
Rattlesnakes are large, venomous snakes that are found throughout North and South America. The greatest concentration of them is in the Southwestern United States and in Northern Mexico.
Some 64 different rattlesnake varieties (species and subspecies) are generally recognized, of which about 30 occur in the United States. Arizona has the most diverse, stateside assemblage with 17. By comparison, Nevadaâs six seem a rather scant array. These snakes are born alive and may live as long as twenty years.
