The spread of invasive species creates serious environmental problems as well as economic hazards for residents and will hamper implementation of parts of the SDCP.

An assessment of the problems that are presented by non-native and introduced species in maintaining native species and natural systems. Divided into two major sections, the study covers representative ecosystems in Pima County as well as representative species that have a negative impact on native species.

A companion to the study issued on July 5, 2000 entitled 'Cactus Ferruginous Pygmy-Owl Investigations in Pima County.' The major objective was to determine whether pygmy-owls chose nest sites or perch trees with characteristics that differ from other available sites within a nesting territory.

Montezuma urges Mike Burns and the McDowell Indians to keep McDowell land and Verde River water; NOT to move to Salt River Reservation as proposed.

Letter to Montezuma from his friend Joshua Russell describing the farming conditions at Santan, Arizona, including irrigation water, crops of wheat, hay, corn and watermelon, and lack of fencing wire for allotted land.

Mike Burns and the leaders of the McDowell community entreat Montezuma to help them stay on their land and help them go to Washington D.C. to request a dam for the irrigation of their land. They also ask him for advice about allotment.

In the letter, Montezuma defends the water rights of the Fort McDowell community and the construction of a proposed dam, and states emphatically that "it is not their wish to move."
