The primary purpose of specialist reports associated with the DEIS is to provide detailed information to assist in the preparation of the DEIS. As the DEIS was prepared, review-driven edits to the broader DEIS resulted in modifications to some of the information contained in some of the specialist reports. As a result, some reports no longer contain information and analysis that was updated through an interdisciplinary review process and is included in the DEIS in its entirety.

  • The Number Is Counterintuitive, but Arizona Ranks Third in the Nation in Terms of Plant Diversity, with Nearly 5,000 Different Species
    Hooded lady’s tresses (Spiranthes romanzoffiana) are one of several orchid species known to grow in the San Francisco Peaks area. WHERE THE WILD ORCHID GROWS The number is counterintuitive, but Arizona ranks third in the nation in terms of plant diversity, with nearly 5,000 different species. Of that number, more than 800 grow in the San Francisco Peaks, including Franciscan bluebells, mountain monardellas, monkeyflowers, graceful buttercups and an orchid commonly known as hooded lady’s tresses. There’s a lot to see in the mountains, so we sent our writer and photographer out to have a look. BY ANNETTE MCGIVNEY PHOTOGRAPHS BY EIRINI PAJAK 38 AUGUST 2017 LENN RINK IS A GUERRILLA BOTANIST. While more traditional scientists are in their labs, staring at computer screens and study- ing DNA models and species databases, Rink is out in the wild, in search of the real thing. He has a reputation among naturalists in the Southwest for hiking far and fast — and for disproving widely accepted assumptions about Arizona’s plants. Rink’s old-school, boots-on-the-ground approach to botany has led to the discovery of new plant species and expanded known ranges for others. And he doesn’t just study plants; he experiences them. “I hike to look at plants,” Rink says as photographer Eirini Pajak and I traipse behind him. We are approaching a pond in Lockett Meadow where Rink suspects some BELOW: Deezchiil Benally, age 7, orchids might be hiding outside their usual habitat. joins her family on a trip to the San It’s the third week in August, and the high meadows in Northern Arizona’s San Francisco Peaks to collect plants for G Francisco Peaks are in the ecological equivalent of the over-full condition humans use in Navajo medicine.

  • Density and Elevational Distribution of the San Francisco Peaks Ragwort, Packera Franciscana (Asteraceae), a Threatened Single-Mountain Endemic
    MADRON˜ O, Vol. 57, No. 4, pp. 213–219, 2010 DENSITY AND ELEVATIONAL DISTRIBUTION OF THE SAN FRANCISCO PEAKS RAGWORT, PACKERA FRANCISCANA (ASTERACEAE), A THREATENED SINGLE-MOUNTAIN ENDEMIC JAMES F. FOWLER AND CAROLYN HULL SIEG USFS Rocky Mountain Research Station, 2500 S Pine Knoll Drive, Flagstaff, AZ 86001 [email protected] ABSTRACT Packera franciscana (Greene) W. A. Weber and A. Lo¨ve is endemic to treeline and alpine habitats of the San Francisco Peaks, Arizona, USA and was listed as a threatened species under the Endangered Species Act in 1983. Species abundance data are limited in scope, yet are critical for recovery of the species, especially in light of predictions of its future extinction due to climate change. This study defined baseline population densities along two transects which will allow the detection of future population trends. Packera franciscana ranged from 3529 to 3722 m elevation along the outer slope transect and densities were 4.18 and 2.74 ramets m22 in 2008 and 2009, respectively. The overall P. franciscana 2009 density estimate for both transects was 4.36 ramets m22 within its elevational range of occurrence, 3471–3722 m. The inner basin density was higher, 5.62 ramets m22, than the estimate for outer slopes, 2.89 ramets m22. The elevation of the 2009 population centroid for both transects was at 3586 (610 SE) m with the inner basin centroid significantly lower than the outer slopes centroid: 3547 (67 SE) m vs. 3638 (67 SE) m, respectively. In mid-September, 6–9% of the P. franciscana ramets were flowering and/or fruiting in 2008–2009.

  • Natural Environment BOS Final
    Natural Environment BOS Final 1 Natural Environment 2 3 Introduction Page | 1 4 The quality of its natural environment defines Coconino County. Dramatic landscapes and 5 recreational opportunities attract visitors and provide amenities to residents. Unfragmented 6 habitats and WILDLIFE CORRIDORS maintain ecological and species diversity. Scenic 7 viewsheds, air quality, water quality, and other environmental features like dark skies provide 8 important quality of life values for residents. Time and again, county residents have supported 9 the conservation and STEWARDSHIP of natural resources, as well as the maintenance and 10 restoration of healthy ECOSYSTEMS. Many county residents have strong, traditional 11 connections with lands, waters, and wildlife that go back many hundreds of years. This Plan 12 strives to honor this relationship by both supporting traditional uses and practices and by 13 promoting wise stewardship of our natural environment. The goals and policies of this chapter 14 reflect this commitment to CONSERVATION of the environment in relationship to land uses 15 that intersect with important natural features. 16 As discussed in the Sustainability and Resiliency Chapter, Coconino County is committed to 17 recognizing the interconnectedness of environmental, economic and social factors in negotiating 18 sustainable land-use outcomes. It is fully acknowledged that a balance must be found between 19 conservation efforts and the recognition of economic trade-offs and private property rights. This 20 important balance will conserve natural systems and landscapes, expand growth in the tourism 21 related economy, and help to maintain property values. 22 This chapter establishes goals and policies that will conserve ENVIRONMENTALLY 23 SENSITIVE FEATURES, wildlife habitat, native plant communities, improve the health of 24 forest ecosystems, minimize soil erosion and improve air quality so that residents continue to 25 enjoy this unique natural heritage.

Löve (Asteraceae) (San Francisco Peaks ragwort) is an alpine-zone endemic of the San Francisco Peaks in northern Arizona. Previous studies have shown that P. franciscana is patchily distributed in alpine-zone talus habitats. The purpose of this study was to describe the relationship between snow duration and P. franciscana abundance. We established trailside transects through P. franciscana habitat along the Weatherford Trail to estimate the abundance of P.
