The purpose of this study was to: 1) examine the effect of Arizona Highways Magazine (AHM) on tourism, 2) determine trip characteristics of AHM subscribers traveling in Arizona, and 3) calculate a benefit/cost ratio for AHM based on the magazine’s cost and revenues as well as the value-added economic impact.
This study investigated whether highways acted as barriers to gene flow for pronghorn in northern Arizona. DNA samples from 132 pronghorn were analyzed using eight polymorphic microsatellite loci. Samples represented animals living on opposite sides of US Route 89 (US 89) and State Route 64 (SR 64). Two different modeling approaches indicated that both US 89 and SR 64, and to a lesser extent US Route 180 (US 180), acted as barriers to gene flow. The genetic structuring caused by highways, especially across US 89, is consistent with behavioral data that demonstrated pronghorn rarely cross this highway. This study found no evidence of inbreeding or reduced genetic variation in any of the populations examined, but those effects may take longer to appear. Based on these results, the researchers recommend future genetic monitoring of these populations or assessment of genetic variation across highways with larger traffic volumes or longer histories to determine whether the barrier effects documented here lead to loss of genetic diversity.
This report examines how effectively Pima County’s natural open-space acquisitions have addressed priorities for conserving species’ habitats and landscape features identified in the Sonoran Desert Conservation Plan. The scope of this study is beyond the County's Multi-Species Conservation Plan, which is a subset of the overall Sonoran Desert Conservation Plan.
The purpose of this study is to provide the U.S. Fish & Wildlife Service with an analysis that identifies anticipated impacts to each of the covered species and asks the question: How effectively will the County's mitigation lands include the specific habitats of covered species under the Multi-Species Conservation Plan?
Develops the methods for using the National Land Cover Dataset to report change by jurisdictions and land ownership by utilizing an existing dataset. Local GIS-based measures of development based on tax assessor records do not provide direct measures of habitat loss.
This study focuses on potential sources within a 10-mile-wide band along the existing interstates, U.S. highways, and state routes within the five-county project area.
An update to the Flagstaff Regional Plan 2030 (FRP30), to bring its Road Network Illustration (Map 25) into compliance with Arizona Revised Statute requirements and to resolve inconsistencies between Map 25 and parts of the Flagstaff City Code. This update does not alter the intent of FRP30; it is only concerned with correcting errors, removing legal vulnerability, and improving the readability of FRP30.
Plan submitted for adoption by the Flagstaff City Council to alleviate motor vehicle congestion in the area known as the Lone Tree Corridor.
A plan for reinvestment in the La Plaza Vieja neighborhood of Flagstaff, Arizona.
A plan for protecting and preserving existing open spaces in response to urban growth in the greater Flagstaff, Arizona area.
