We conducted an economic analysis of two case study stewardship contracts on the Mount Hood National Forest in western Oregon. Stewardship contracting has been embraced by some federal managers to achieve restoration goals while providing economic benefits to local communities. Little is known about economic contributions from stewardship contracts, including how they compare against Secure Rural Schools funding or the century-old payments to counties revenue sharing system. Using expenditure data from sale purchasers, contractors, and fiscal agents, we developed methodology to track...

In this chapter, we examine the scientific basis of the assumptions, management strategies, and goals of the Northwest Forest Plan (NWFP, or Plan) relative to the ecology of old-growth forests, forest successional dynamics, and disturbance processes. Our emphasis is on “coarse-filter” approaches to conservation (i.e., those that are concerned with entire ecosystems, their species and habitats, and the processes that support them) (Hunter 1990, Noss 1990). The recently published 2012 planning rule has increased emphasis on land management rooted in ecological integrity and ecosystem...

Climate Change and Rocky Mountain Ecosystems describes the results of a cutting-­edge effort to assess climate change vulnerabilities and develop adaptation options for ecosystems in the Northern Rocky Mountains region of the United States, focusing on national forests, grasslands, and parks in Northern Idaho, Montana, North Dakota, Northern South Dakota, and the Greater Yellowstone Ecosystem. Building on a framework developed in previous subregional climate change efforts, the Northern Rockies Adaptation Partnership (NRAP) was the first regional-scale, multi-resource climate change...

Like many other high elevation alpine tree species, Rocky Mountain bristlecone pine (Pinus aristata Engelm.) may be particularly vulnerable to climate change. To evaluate its potential vulnerability to shifts in climate, we defined the suitable climate space for each of four genetic lineages of bristlecone pine and for other subalpine tree species in close proximity to bristlecone pine forests. Measuring changes in the suitable climate space for lineage groups is an important step beyond models that assume species are genetically homogenous. The suitable climate space for bristlecone pine...

We examined spatial patterns of post-fire regenerating conifers in a Colorado, USA, dry conifer forest 11-12 years following the reintroduction of mixed-severity fire. We mapped and measured all post-fire regenerating conifers, as well as all other post-fire regenerating trees and all residual (i.e., surviving) trees, in three 4-ha plots following the 2002 Hayman Fire. Residual tree density ranged from 167 to 197 trees ha-1 (TPH), and these trees were clustered at distances up to 30 m. Post-fire regenerating conifers, which ranged in density from 241 to 1036 TPH, were also clustered at...

This study introduces a large fire containment strategy that builds upon recent advances in spatial fire planning, notably the concept of potential wildland fire operation delineations (PODs). Multiple PODs can be clustered together to form a “box” that is referred as the “response POD” (or rPOD). Fire lines would be built along the boundary of an rPOD to contain a large fire. Assets such as communities and infrastructure within an rPOD could be protected through “point zone protection.” We develop a mixed integer program model to optimally aggregate PODs into an rPOD with an objective of...

American chestnut (Castanea dentata Borkh.) was a dominant tree species in its native range in eastern North America until the accidentally introduced fungus Cryphonectria parasitica (Murr.) Barr, that causes chestnut blight, led to a collapse of the species. Different approaches (e.g., genetic engineering or conventional breeding) are being used to fight against chestnut blight and to reintroduce the species with resistant planting stock. Because of large climatic differences within the distribution area of American chestnut, successful reintroduction of the species requires knowledge and...

An analysis of the urban forest in New York, New York, reveals that this city has an estimated 7.0 million trees (encompassing all woody plants greater than one-inch diameter at breast height [d.b.h.]) with tree canopy that covers 21 percent of the city. The most common tree species across public and private land are Norway maple, northern white-cedar, tree-ofheaven, sassafras, and white oak, but the most dominant species in terms of leaf area are Norway maple, London planetree, black locust, pin oak, and red maple. Trees in New York City currently store about 1.2 million tons of carbon...

In this paper, we propose that spiritual approaches rooted in the practice of Hawai‘i ritual provide a powerful portal to revealing, supporting, and enhancing our collective aloha (love, fondness, reciprocity, as with a family member) for and dedication to the places and processes that we steward. We provide a case study from Hawai‘i, where we, a group of conservation professionals known as Hālau ‘Ōhi’a, have begun to foster a collective resurgence of sacred commitment to the places and processes we steward through remembering and manifesting genealogical relationships to our landscapes...
