Typical plants of the desert flats and slopes are creosote bush, mesquite, cactus, yucca, and agave. Cottonwood, sycamore, and several species of willow flourish along streams and washes. You can see all of these plants within the monument boundaries—many of them on the nature trail below Montezuma Castle.
The monument, situated on the northern limit of the Lower Sonoran plant zone, exhibits other plants more typical of the higher region a few miles to the north where the Upper Sonoran zone begins. Some of these are hackberry, juniper, sumac, and Indian paint brush.
The plant collections at Montezuma Castle include 167 species representing 49 families. The wide variety of plants within this relatively small area attracts birds and small animals in their search for food. Undoubtedly these plants were an aid in supplementing the diet of the prehistoric Indians. Many wild plants were and still are used by the Indians of the Southwest for other purposes—basketry and sandal weaving, medicines, and ceremonial uses.

In 1948 a preliminary survey was made of the plants in the Montezuma Well section—189 different plants representing 60 families were collected in that area alone. The variety of plantlife for food or other uses, in addition to the amazing water supply, made the Well a very attractive area for Indian settlement.
Many birds have been observed in the monument—149 bird species have been recorded at the Castle in 19 years of observation; and 140 species have been recorded at the Well since 1948. Many birds live in the region throughout the year, while others are seasonal visitors. Ducks and geese are plentiful in the winter, particularly at Montezuma Well, where they rest between their long flights.
The animals and reptiles of the monument are typical of this desert area. Most common are jackrabbit, cottontail rabbit, porcupine, raccoon, beaver, skunk, ground squirrel, rock squirrel, rattlesnake, bull snake, and water snake. Other forms of life which are present in the summer are lizard, black widow spider, tarantula, scorpion, centipede, and cicada (locust).
