Mr. Proudfoot, the leading pygmy-owl biologist in the United States, has worked for the last two years to gather and analyze the data that allows us to address issues regarding the genetic viability of ferruginous pygmy-owls in Arizona and to establish a framework for future management efforts. The two major questions addressed are (1) do populations of concern lack genetic variation relative to putative healthy populations, and (2) how unique are geographically distinct populations within a species of special concern?
The purpose of this study is to (1) develop a fundamental understanding of the problems that exist, and (2) perform a cursory examination of possible management approaches identifying those that appear most plausible for further consideration.
The primary need for these realignments is due to the planned airport expansion at Tucson International Airport. The purpose of this report is to compare various alignment alternatives for the realignment on the basis of access, cost, right-of-way, and floodplain impacts.
