PROJECT:  2015/2016 Lands with Wilderness Characteristics (LWC) Inventory
CLIENT:   Arizona Wilderness Coalition
LOCATION: Bureau of Land Management Kingman & Safford Resouce Areas
PARTNERS:   The Wilderness Society, Pew Charitable Trusts
YEAR: 2015-2016
DESCRIPTION:  Wilderness is an essential component of Americas multiple-use public lands management framework. Most of Arizona's 90 designated Wilderness Areas were established on BLM land in 1990, following 12 years of field inventory and planning by the agency, the then-new Arizona Wilderness Coalition, and other entities. Since that time, much has changed in Arizona, including BLM land excahnges, growing cities, public demand for outdoor recreation, and other trends in resource extraction & protection. Recognizing that Wilderness is a cherished resource, but congressional inaction generally prevents the designation of new Wilderness Areas, in 2011, the U.S. Department of the Interior revised the BLM's administrative options and responsibilities for protecting wilderness character on our public lands. The Arizona Wilderness Coalition, again, is leading the effort to develop citizens proposals for the protection of wilderness values, but this time the outcome sought after is not immedeate congressional designation, but a new administrative option, called "Lands with Wilderness Characteristics". Hassayampa Forestry & Ecological has been "the boots on the ground" for the past year in the Kingman and Safford areas of BLM land, mapping, documenting, and developing proposal reports for the administrative protection of some of Arizona's last remaining truly wild, unprotected deserts, grasslands, and woodlands. Our proposals would protect some of the state's best bighorn sheep, pronghorn, & native fish habitat, some of the most wild streams & canyons, and our cherished scenic vistas.

PROJECT:  2014 Carson National Forest Stand Exams
CLIENT:   Chestnut Ridge Forestry; US Forest Service-Carson National Forest
LOCATION:  Tres Piedras Ranger District, Carson National Forest, New Mexico
PARTNERS:   Chestnut Ridge Forestry, Cloudcroft, New Mexico; New Mexico Collaborative Forest Restoration Program (Gilbert Vigil, Grantee)
YEAR: 2014
DESCRIPTION:  Hassayampa Forestry provided field operations management for a crew of 8 during the 2014 field season, collecting stand exam data for use by the US Forest Service as part of the New Mexico Collaborative Forest Restoration Program (CFRP).  The study area was a 19,500 acre portion of the Rio Tusas and Rio San Antonio watersheds in the continental divide area of northern New Mexico.  The crew visited 1560 inventory plots in forests ranging from 8500-10,800 feet.

PROJECT:  2013 US Forest Service Stand Exams
CLIENT:   Chestnut Ridge Forestry; US Forest Service-Kaibab National Forest
LOCATION:  Williams, Chalender, and Tusayan Ranger Districts - Kaibab National Forest in Arizona
PARTNERS:   Chestnut Ridge Forestry, Cloudcroft, New Mexico
YEAR: 2013
DESCRIPTION:  The 2013 Kaibab Stand Exam primarily focuses on forest areas undergoing major change.  Study areas include the Cross Fire in the vicinity of Round Mountain, thinned stands near Davenport Lake, a major sawfly defoliation event on Kendrick Peak, and the X Fire south of the Grand Canyon.

PROJECT:  2012 US Forest Service Aspen Monitoring
CLIENT:   Chestnut Ridge Forestry; US Forest Service-Kaibab National Forest
LOCATION:  Williams Ranger District - Kaibab National Forest in Arizona
PARTNERS:   Chestnut Ridge Forestry, Cloudcroft, New Mexico
YEAR: 2012
DESCRIPTION:   The 2012 season included establishing permanent monitoring plots in dozens of Aspen sites in northern Arizona.  Sites are within the Kendrick Mountain Wilderness Area, around and on Sitgreaves Mountain, Bill Williams Mountain, and other areas of the forest.  Our data is used to evaulate the condition of aspen forests in the area, including insect and disease occurence, wildlife herbivory, and regeneration following the many fires that have occured within these stands.  We observed a wide range of conditions-ranging from sites that are succeeding to mixed conifer, to vigorous regeneration on severely burned mountainsides. We are also establishing plots within fenced areas to keep wildlife out, as elk are a significant impact on young stands.   For years we have felt the solution to "aspen decline" in the west is fire  -- big, hot fires -- and these sites prove it!

PROJECT:  2011 US Forest Service Stand Exams
CLIENT:   Chestnut Ridge Forestry; US Forest Service
LOCATION:  Kaibab, Apache-Sitgreaves & Arapahoe-Roosevelt National Forests in Arizona and Colorado
PARTNERS:   Chestnut Ridge Forestry, Cloudcroft, New Mexico
YEAR: 2011
DESCRIPTION:   Our 2011 season was filled to the brim with work on 3 National Forests in Colorado and Arizona.  We've subcontracted our field services to Joel Fyock and Chestnut Ridge Forestry.  We are currently conducting Common Stand Exams which include basic tree measurements, fuel and downed woody debris measurements, and identification of forest pest and disease occurences.  We have been privileged to work in incredible old-growth ponderosa pine, white fir, lodgepole, and mixed conifer forests.
A major highlight of this work was having to evacuate the KP Creek Area of the Blue Range Primitive Area in Arizona after the Wallow Fire ignited in the Bear Wallow Wilderness Area.  That fire has since grown to the largest in Arizona history; our plots have since burned!

Sonoran Desert Invasive Species Research Program
CLIENT:   Northern Arizona University Lab of Landscape Ecology & Conservation Biology
LOCATION:  Southwestern Arizona's Sonoran desert
YEAR: 2011
DESCRIPTION:  Joe was hired for a short-term winter position as a crew leader conducting botanical data collection across a vast area in the Sonoran desert.  Over three months he traveled extensivly in the area, including to Organ Pipe Cactus National Monument, Kofa National Wildlife Refuge, Cabeza Prieta National Wildlife Refuge, Sonoran Desert National Monument, McDowell Mountain Park, Barry Goldwater Air Force Range, Yuma Proving Ground, and many more remote, and sometimes not so remote places.  The purpose of this work is to collect field data to use in the modelling and prediction of invasive species outbreaks using LandSat and MODIS satellite imagery.  To learn more about the project, visit the LLECB facebook page at

PROJECT:  Kirchner Woods Multi-Use Non-Motorized Trail System
CLIENT:   Stowe Land Trust
LOCATION:  Taber Ridge, Worcester Mountains, Stowe, Vermont
PARTNERS:   Hardy Avery, Sustainable Trailworks, numerous volunteers
YEAR:  2009-2010
DESCRIPTION:   Together with Hardy Avery of Sustainable Trailworks of Morrisville, Vermont, we completed the installation of an incredible 3 mile non-motorized multiple use trail system for the Stowe Land Trust. A wide machine-built path leads 1/4 mile from the signed parking lot to a historic sugarhouse, where users can choose from easy loop walks on upgraded woods roads, a 1/2 mile singletrack loop, and a 1/2 mile spur with a loop around the top of Taber Hill. The trails are great for hiking, mountain biking and winter uses, and have been well received by local recreationists. For information on how to find the trails at Kirchner Woods, contact the Stowe Land Trust online.
SIMILAR PROJECTS:   We have built and maintained non-motorized trails for numerous private landowners, the U.S. Army Corps of Engineers McDowell Lake Flood Control Area, the Greenfield Trails Association, and have provided trail crew leadership to the Monadnock Conservancy and Eastern Mountain Sports employee volunteers

PROJECT:   Lyndeborough Natural Resources Inventory
CLIENT:   Town of Lyndeborough, New Hampshire
LOCATION:   Eastern Monadnock Region, Lyndeborough, New Hampshire
PARTNERS:   Lyndeborough Conservation Commission, numerous volunteers
YEAR:   2008-2009
DESCRIPTION:   A comprehensive inventory and review of the flora, fauna, geology, landforms, and conservation concerns for the 40,000 acre township.  Nearly 1000 field hours over 18 months yielded one of the most detailed inventories completed in southern New Hampshire, and the most comprehensive ever conducted for Lyndeborough.  Abundant GIS mapping and analysis based on field data provided high-resolution maps of wildlife habitat, water resources, geology, vegetation, and priorities for conservation.
SIMILAR PROJECTS:   We have provided wetlands mapping and assessment, wildlife inventories, and other related services for municipalities, non-profit organizations and private landowners, and wetland delineation support services for wetland scientists.

PROJECT:    Centennial Valley Environmental Review
CLIENT:   Center for Earth Concerns, Wildlife Land Trust, Pegasus Foundation
LOCATION:   Southwestern Montana's Centennial Valley
PARTNERS:   Grand Canyon Trust, Stephen Sontag
YEAR:   2007
DESCRIPTION:   A qualitative field inventory, stakeholder interviews, and exploration of conservation issues, combined with an intensive literature review, GIS database development, and investigation of land-use history all came together to produce an exhaustive review of historic and contemporary environmental conditions and concerns for the 370,000 acre Centennial Valley, one of our nation's biological hot-spots.  The report, which was heralded by the Greater Yellowstone Coalition, lays an informational foundation for the development of an environmental research and education station adjacent to the headquarters of the Red Rock Lakes National Wildlife Refuge.

PROJECT:   Environmental History of the Kane & Two-Mile Ranches
CLIENT:   Grand Canyon Trust
LOCATION:   Eastern Arizona Strip, Grand Canyon Bioregion, Kane & Two-Mile Ranches
PARTNERS:   Grand Canyon Trust
YEAR:   2005-2006
DESCRIPTION:   A detailed review of Native American ethnography, early accounts, historical biological data, and contemporary scientific investigations, combined with extensive field exploration culminated in a report that describes environmental conditions and ecosystem development over the past 40,000 years for the still-wild and very diverse Arizona Strip region.  The Grand Canyon Trust uses this document as a teaching tool for volunteer land stewards, and as a reference for the management of the 850,000 acres of public land on which they hold grazing leases, and several thousand acres they own outright.

PROJECT:   Forest Ecosystem Inventory & Management Plan
CLIENT:   Farm at the Edge, a private non-industrial family forest
LOCATION:   Piscataquog Mountain, Lyndeborough, New Hampshire
YEAR:   2009-2010
DESCRIPTION:   We had the privilege of working with the wonderful family-owners of 360 acres of beautiful forest at the edge of the Monadnock Highlands.  We provided an inventory of natural communities, wildlife habitat, flora, fauna, wetlands, and forest stands to help develop a long-term management approach to meet their needs of habitat protection, old-growth retention, timber production, and watershed restoration.  Extensive stands of hemlock, pine, and oak were found to exceed 250 years of age. Evidence of wildfire, hurricane, microburst, ice storms, agricultural land-clearing, past logging, and insect & disease outbreaks provided a unique long-term perspective on the development of forests in central New England.  Our recommendations included creating old-growth forest reserves, timber stand improvement thinnings, wildlife habitat patch-cuts, trail building, view clearing, planting of native species, and more.  Because we cannot carry through with all of our recommendations across the country, we have selected Geoff Jones of Loveland Forestry of Stoddard, NH as a partner in management.
SIMILAR PROJECTS:   We have developed many management plans for private family forests throughout New England, focusing on a holistic approach to ecosystem protection, wildlife habitat restoration, and sensible resource extraction.

PROJECT:   Ecological Inventory, Stewardship Plan, & Wildlife Habitat Creation
CLIENT:   private non-industrial family forest
LOCATION:   Monadnock Highlands, Spectacle Pond, Roxbury, New Hampshire
YEAR:   2008-2010
DESCRIPTION:   A long-term inventory of this private forestland cataloged flora, fauna, natural communities, wetlands, habitat, and geological features.  A principal outcome of this inventory was to develop long-term wildlife habitat management strategies.  The first recommendation was the creation of early-successional mixed forest to break up the extensive contiguous mature forest canopy.  A 2 acre area of 75-100 year old mixed hemlock-pine-oak forest was determined to be a suitable site due.  We harvested over 60 cords total volume off of this small site in firewood, sawlogs, and pulp that all stayed in the local area.  The residual stand of multi-aged hardwoods and conifers, with more than ten tree species, was planted with native grasses, shrubs, and vines after burning and chipping residual slash and debris.
SIMILAR PROJECTS:   We have developed management plans for private family forests and land trusts in New England.  We have overseen and conducted timber harvests for wildlife, revenue, fuels reduction, aesthetics, and forest health.

The Aquarius Mountains form the eastern edge of the Big Sandy River Valley. Most of this range was acquired by BLM through exchanges with private land in the 1990's, so this area has not been inventoried for Wilderness Character. We identified a 35,000 and a 55,000 acre roadless area in this rangePrime bighorn sheep habitat, excellent desert hiking, and remote, pristine silence make the Black Mesa proposed LWC one of western Arizona's jewels.The Black Mountains form the eastern edge of the vast Colorado River Valley of western Arizona. This range has long been recognized for its wilderness values, including Arizona's most important bighorn sheep habitat.The Hualapai Mountains are the furthest north of Arizona's sky island mountain ranges. From Joshua tree woodlands to old-growth ponderosa pine forests, the Hualapais represent the best opportunity for protecting a large ecological gradient in northwestern Arizona.The scenic backdrop to the town of Meadview, and the dominant scene when driving to the Hualapai Skywalk at the Grand Canyon, the Grand Wash Cliffs are a vast, pristine desert ecosystem featuring the worlds most intact Joshua Tree forest, prime raptor habitat, and Native American Ruins.The Poachie Range proposed LWC would add protections to 25,000 acres of upper Sonoran desert and woodland adjacent the Arrastra Wilderness Area, including this rare granite arch.The Scratch & Jerky Canyons area of Upper Burro Creek is one of the most remote and innaccesible perrenial rivers in Arizona. Pristine, clear water, native fish, and rare hawks make for a sublime backpacking destination.The Lower Burro Creek proposed LWC features miles of deep canyons, running water, diverse wildlife, and stunning geology.
