  • Chapter 1: Introduction
    Chapter 1. Introduction Community vision meetings during Forest Plan Revision Location The Prescott National Forest (Prescott NF) is one of six national forests in Arizona (figure 1). It covers approximately 1.2 million acres in west-central Arizona and is located in Yavapai and Coconino Counties. The Prescott NF consists of two geographically separate land areas (eastern and western) that are administered as three ranger districts: the Chino Valley Ranger District, which covers the areas east and west of Chino Valley; the Bradshaw Ranger District, which covers the area near Prescott and south into the Bradshaw Mountains; and the Verde Ranger District, which covers the area just north of Jerome and Clarkdale and along the southern side of the Verde Valley. The Prescott NF shares boundaries with: the Coconino, Kaibab, and Tonto National Forests; the Agua Fria National Monument; Bureau of Land Management - Hassayampa Field Office; Arizona State Trust lands; and several communities including Prescott, Camp Verde, and Cottonwood. Role and Contributions of the Planning Area The Prescott NF is located in a comparatively mountainous section of central Arizona between the forested plateaus to the north and the arid desert region to the south. Roughly half of the Prescott NF lies west of the city of Prescott, Arizona, in the Juniper, Santa Maria, Sierra Prieta, and Bradshaw Mountains. The other half of the Prescott NF lies east of Prescott and takes in the Land and Resource Management Plan for the Prescott NF 1 Chapter 1. Introduction terrain of Mingus Mountain, the Black Hills, and Black Mesa. Elevations range between 3,000 feet above sea level along the lower Verde Valley to 7,979 feet at the top of Mount Union, the highest natural feature on the national forest.

  • Viability Analyses for Vascular Plant Species Within Prescott National Forest, Arizona
    Viability analyses for vascular plant species within Prescott National Forest, Arizona Marc Baker Draft 4 January 2011 1 Part 1. Description of Ecological Context (Adapted from: Ecological Sustainability Report, Prescott National Forest, Prescott, Arizona, April 2009) Description of the Planning Unit Prescott National Forest (PNF) includes mostly mountains and associated grassy valleys of central Arizona that lie between the forested plateaus to the north and the arid desert region to the south. Elevations range between 3,000 feet above sea level along the lower Verde Valley to 7,979 feet at the top of Mount Union, the highest natural feature on the Forest. Roughly half of the PNF occurs west of the city of Prescott, Arizona, in the Juniper, Santa Maria, Sierra Prieta, and Bradshaw Mountains. The other half of the PNF lies east of Prescott and takes in the terrain of Mingus Mountain, the Black Hills, and Black Mesa. The rugged topography of the PNF provides important watersheds for both the Verde and Colorado Rivers. Within these watersheds are many important continuously or seasonally flowing stream courses and drainages. A portion of the Verde River has been designated as part of the National Wild and Scenic Rivers System. Vegetation within PNF is complex and diverse: Sonoran Desert, dominated by saguaro cacti and paloverde trees, occurs to the south of Bradshaw Mountains; and cool mountain forests with conifer and aspen trees occur within as few as 10 miles upslope from the desert . In between, there are a variety of plant and animal habitats including grasslands, hot steppe shrub, chaparral, pinyon-juniper woodlands, and ponderosa pine forests.

The project area is located on lands administered by the Bureau of Land Management (BLM) within the boundaries of the Kingman Field Office (KFO) in the northwest quarter of Section 21, Township 16½ North, Range 11 West. The purpose of this BE is to address the regulations of the Endangered Species Act (ESA) of 1973, as amended, and management regulations of the BLM. The scope of work for this BE included: review of the U.S. Fish and Wildlife Service (USFWS) species list for Mohave County; review of the BLM sensitive species list for the KFO; review of the Arizona Game and Fish Department (AGFD) online occurrence records for special-status species near the project area; survey for noxious weeds; field reconnaissance of the property; and evaluation of the potential for the species listed in this report to occur in the project area.

  • Hualapai Mexican Vole Conservation Status Review
    August 02, 2015 Hualapai Mexican Vole Conservation Status Review PREPARED BY Amanda Aurora, C.W.B . Eleanor Gladding Regional Scientist / Project Manager Senior Biologist/Project Manager SWCA Environmental Consultants - Austin SWCA Environmental Consultants - Tucson 4407 Monterey Oaks Boulevard, Building 1, Suite 110 343 West Franklin Street Austin, Texas 78749 Tucson, Arizona 85701 [email protected] [email protected] Introduction The Hualapai Mexican vole or Hualapai vole ( Microtus mexicanus hualpaiensis ) is a cinnamon-brown, small mammal in the Cricetidae Family. In January of 1987, the U.S. Fish and Wildlife Service (USFWS) proposed to list the Hualapai Mexican vole as endangered under the Endangered Species Act (ESA) and published the final listing rule in October 1987 (USFWS 1987a; USFWS 1987b). At that time, the species was considered “extremely rare and has among the most restricted habitats of any North American mammal” (USFWS 1987b). The USFWS in the final listing rule identified up to 14 locations in the Hualapai Mountains of west-central Arizona where the Hualapai Mexican vole (or its sign) had been observed (USFWS 1987b) (Figure 1). The USFWS also noted that “from 1923 to the present, only 15 specimens are known to have been captured in the Hualapai Mountains” (USFWS 1987b). This subspecies was differentiated by morphological characteristics from the other subspecies of Microtus mexicanus that occur in Arizona, including M. mexicanus mogollonensis and M. mexicanus navaho . The primary morphological differences differentiating the Hualapai Mexican vole from the other subspecies include: slightly longer body, longer tail, and longer and broader skull (compared to M. mexicanus navaho ) and a longer body, shorter tail, and a longer and narrower skull (compared to M.

  • Southern Bradshaw Mountains (Yavapai County) June 14-16, 2019
    Southern Bradshaw Mountains (Yavapai County) June 14-16, 2019 By Eric Hough The rugged terrain and mix of chaparral and pine-oak forest typical of the southern Bradshaw Mountains (photo © Eric Hough). Introduction The Bradshaw Mountains in central Arizona include a wide area of chaparral, pinyon-juniper and oak woodlands, ponderosa pine-Gambel oak forest, mixed conifer forest, and deciduous riparian woodland drainages, which include the headwaters of the Agua Fria and Hassayampa Rivers. While the northern part of the range nearest Prescott is regularly covered by local birders, the southern half is seldom-visited and there is a significant lack of eBird data for that area. As examples of this, doing an eBird search for two of the most common species expected (Woodhouse’s Scrub-Jay and Spotted Towhee) produced fewer than 10 checklists reporting each of these species! The Breeding Bird Atlas surveys in the early 1990s (Corman & Wise-Gervais 2005; hereafter referred to as the “Atlas”) did at least partially cover this area and found mostly expected species, but did not detect some possible higher elevation breeders such as Northern Pygmy- and Northern Saw-whet owls, Dusky Flycatcher, Warbling Vireo, Purple Martin, Red- breasted Nuthatch, Red Crossbill, and Pine Siskin. Recent range expansions northwestward of species such as Dusky-capped Flycatcher and Rivoli’s Hummingbird into the northern Bradshaws and other nearby ranges had not yet been found here either. For this early summer expedition, we focused on the mid to high elevations of the southern Bradshaws to see which breeding species were present. The timing of this expedition was also chosen due to the near full moon, which promised better conditions for detecting owls and nightjars.
