Whitebark pine (Pinus albicaulis) forests are declining across most
of their range in North America because of the combined effects of
mountain pine beetle (Dendroctonus ponderosae) outbreaks, fire
exclusion policies, and the exotic pathogen Cronartium ribicola,
which infects five-needle white pines and causes the disease white
pine blister rust. The loss of this high-elevation tree species
poses serious consequences for upper subalpine ecosystems, both in
terms of impacts on biodiversity and losses in ecosystem processes;
whitebark pine is now a candidate species for listing under the
Endangered Species Act. Large, nutritious seeds produced by
whitebark pine are an important food for many bird and small mammal
species, as well as grizzly (Ursus arctos horribilis) and black
bears (Ursus americanus), and whitebark pine communities provide
habitat for many additional wildlife species. Whitebark pine seed
dispersal by Clark's nutcrackers (Nucifraga columbiana) combined
with hardy seedlings results in early whitebark pine community
development after fire and other disturbances; whitebark pine
seedlings survive on harsh, arid sites and may act as nurse trees
to less hardy conifers and vegetation. Whitebark pine at higher
elevations, where it is common in many regions, helps regulate snow
melt and reduce soil erosion. For these collective functions,
whitebark pine is considered both a keystone species for promoting
community diversity and a foundation species for promoting
community stability. Since more than 90 percent of whitebark pine
forests exist on public land in the United States and Canada, it is
important that government natural resource management agencies play
an important role in ensuring future presence of this tree species
by initiating concerted, coordinated, and comprehensive restoration
efforts. This is best accomplished through a coordinated,
trans-boundary restoration strategy that includes shared
infrastructure and expertise for conserving seeds, growing blister
rust-resistant seedlings, protecting trees, restoring ecosystem
processes, and promoting natural regeneration. We detail a
multi-scale strategy for restoring whitebark pine across its range
in the western United States and Canada. The strategy was compiled
by researchers, land managers, and resource specialists for use as
a reference for prioritizing, designing, and implementing
successful whitebark pine restoration activities across many scales
from stands to landscapes to its entire range. The whitebark pine
restoration strategy consists of the following principles: (1)
promote rust resistance, (2) conserve genetic diversity, (3) save
seed sources, and (4) employ restoration treatments. These guiding
principles are then used to implement the whitebark pine
restoration strategy using a set of possible actions: 1. assess
condition, 2. plan activities, 3. reduce pest impacts, 4. gather
seed, 5. grow seedlings, 6. protect seed sources, 7. implement
restoration treatments, 8. plant burned areas, 9. support research,
and 10. monitor activities. The strategy is also organized by six
spatial scales of analysis and organization: 1. range-wide, 2.
region (National Forest Region or Provincial Regions), 3. forest
(National Forest, National Park, and Canadian Forest District), 4.
landscape (watershed or landform), 5. stand, and 6. tree. At each
scale, we present four important factors in the restoration
strategy: (1) assessment, (2) restoration actions, (3) management
concerns, and (4) an example. Strategic restoration plans are
presented for the coarse-scale strategies, while illustrated
examples are presented for the finer scales (tree, stand, and
landscape).
In response to the 2002 fire season's fatal aircraft accidents, the
USDA Forest Service and USDI Bureau of Land Management (BLM)
jointly established an independent, five member Blue Ribbon
Commission (the panel - Appendix A) to identify essential
information for planning a safe and effective future aviation
program. On August 15, 2002, the Chief of the Forest Service and
Director of the BLM asked the panel to identify weaknesses and fail
points in the current aviation program, focusing on safety,
operational effectiveness, costs, sustainability, and strategic
guidance. Assuming an integrated approach, the agencies tasked the
panel to address these five areas as they relate to the operation
and supervision of air tankers, lead planes and air supervision
modules, helicopters, and air attack platforms (Appendix B). Within
a 90-day period, the panel held town hall meetings in Atlanta,
Portland, Salt Lake City, Denver, Albuquerque, and Sacramento,
soliciting comments and ideas from those with an interest in the
federal firefighting aviation program. The Federal Aviation
Administration, National Transportation Safety Board, California
Department of Forestry and Fire Protection, and Canadian and United
States air tanker operators, Conair and Aerounion, respectively,
also provided special briefings to the panel. Verbal and written
remarks were received from aerial firefighting-industry officials,
air tanker contractors, aircraft manufacturers, fixed-wing and
helicopter pilots, private-sector consultants, and concerned
people. In addition, the panel heard commentary from
representatives of state and federal agencies responsible for
fighting wildland fires. The massive amount of material and brief
time for analysis forced the panel to address, for the most part,
only major considerations. Possibly the single largest challenge
now facing leaders of these federal agencies is to foster
cooperation and collaboration among working-level staffs,
contractors, and states to raise the standards of aerial wildland
firefighting in the United States. This report presents eight key
findings, which the panel believes are critical for planning a safe
and effective future firefighting aviation program. The panel
relied significantly on the knowledge, experience, and judgment of
its members to develop its findings, which are strong inferences
rather than deduced certainties. The panel's mandate was to
identify problems, not advocate solutions or make recommendations.
The purpose of this Change Management and Implementation Guide is
to provide the US Forest Service's Fire and Aviation Management
with pertinent information to help build a strategy when faced with
an operational change. This includes change to the agency, a
particular program or any other change that has potential to
significantly impact personnel or operations whether originating
from inside or outside the agency. As directed from the Chief's
Safety Policy, "The prevention of accidents can only occur if we
commit to safe work practices, continually assess our changing
environment, refuse to assume unacceptable risks, and continually
address unsafe conditions." Change often introduces hazards that
are unknown or unforeseen due to the fact that something different
has been introduced into a known and familiar method. In an attempt
to proactively expose these hazards, a processed approach to
introducing Change and managing people and systems through the
transition period is a critical strategy for success. This plan is
dynamic and should be utilized to best meet the scope and scale of
each change process. It should also be updated as better practices
are identified. Knowledge gained through implementation as well as
reviews during continuous improvement processes must contribute to
additional versions of this plan. Revision control should be
annotated on the Revision Control log within the US Forest Service
Safety Management System Guide.
Most experienced trail crews try to avoid wetlands because of the
construction and maintenance problems they pose. Little has been
published on wetland trail construction, and materials that are
available are often outmoded or are too regionally focused. By
pulling this information together from our experiences, we hope to
answer questions you didn't even know you had. In this manual we
have described the common techniques for building a wetland trail.
We have also included information on some of the more unusual
materials and tools. Some of the techniques and tools we describe
are suitable for wilderness situations where mechanized equipment
cannot be used. Others are suitable for urban greenbelts where a
wider range of techniques, material, and equipment can be used.
Somewhere in between are the back-country sites where machines are
permitted, but access and logistics are challenges. Although this
book is written for wetland trails, the techniques described can
also be used for correcting other poorly drained low areas in
existing trails. The manual is written for those who are untrained
and inexperienced in wetland trail construction, but those with
experience may learn a few things, too.
