PNW RESEARCH STATION
LONG-TERM
SITE PRODUCTIVITY PROGRAM CHARTER
PROBLEM STATEMENT
AND JUSTIFICATION
Problem:
Land management agencies cannot accurately predict the effects of
management practices on long-term site productivity for the purposes of meeting
state and federal laws and regulations.
Land managers need new knowledge from research to design forest
management systems whose sustainability is more certain. Management standards and monitoring systems
need to evolve as new information from research becomes available. We need new approaches to research that
incorporate longer time perspectives, link basic and applied research, and
provide better overall coordination to improve our ability to predict
management effects.
There are many
definitions of long-term site productivity (e.g. economic, ecosystem, soil)
within the research and management communities. These definitions reflect differences in perspective and desired
approach. Our working definition of
long-term site productivity conceptually encompasses the productivity over long
periods of time (three or more rotations of tree crops) of the entire forest
ecosystem as determined by the cumulative interaction of soil, biota, chemical
and physical climate, natural disturbance, and management practices. From a pragmatic perspective, this program
will initially emphasize management practices, soil processes, and potential
productivity as measured by growth of dominant vegetation. This initial focus, however, will not
inhibit consideration or study of other components of ecosystems or the
socio-economic implications of management decisions. Further definition of productivity and potential productivity
will be a research priority under this program.
Long-term site
productivity is one of the most complex issues facing scientists and managers
concerned with forest land management.
Difficulties result from the long-term (centuries) nature of the issue
itself, site-to-site variability, difficulty in establishing controls, multiple
confounding effects including changes in climate and desired products, and an
inadequate understanding of how interacting and interdependent ecosystem
processes affect productivity. We need
to improve our ability to identify actual or potential problems and
opportunities; to develop methods to avoid, minimize, or ameliorate negative
effects of management; to learn how to improve productivity wherever
appropriate; and to develop a practical system for land managers to assess
positive and negative effects of management activities as a basis for refining
management decisions and guidelines.
The need for a
long-term site productivity program evolves from Congressional mandates, public
interest, and lack of synthesis of fragmented and short-term research. This has been emphasized by WO management
reviews, Region 6 staff reviews, and several PNW Research Station committees
and task forces. The latest such
effort, "Report of the Long-term Productivity Task Force, Dec. 7,
1987", chaired by Dean DeBell (PNW-Olympia), recommended that the PNW
Research Station spearhead a research and development program in cooperation
with Region 6, Region 10, and the Bureau of Land Management. This Charter relies heavily on the DeBell Report
and consultation from R-6 and BLM. Applicable
laws and broad public concerns mandate that the health and productive capacity
of forest ecosystems be sustained.
Applicable laws and broad public concerns mandate that the health and
productive capacity of forest ecosystems be sustained. The Oregon and California Railroad Act of
1937 (which covers BLM lands) states that "Lands valuable for timber shall
be managed for permanent production...in conformity with the principle of
sustained yield." The National
Forest Management Act of 1976 and the National Environmental Protection Act of
1969 and state that federal forest lands are to be managed without
"substantial and permanent impairment of the productivity of the
land." No legal interpretation of
this National Forest Management Act provision has been established, but the
Office of General Counsel believes it refers to "long-term" soil
productivity (the WO-National Forest System Soil Productivity Task Group, Sept.
9, 1987).
Public concern
about long-term productivity is increasing.
The current scarcity of relevant scientific results has contributed to
an increased uncertainty and skepticism about the appropriateness of current
forest practices. This potential lack
of trust in federal land stewardship leads to a greater probability that forest
management activities on federal lands will be increasingly legislated or
controlled by judicial decisions.
National Forests and BLM are required to inform the public about current
and future policies and programs related to forest management and site productivity
on federal forest lands. In addition,
the PNW Research Station needs to summarize and make known to forest managers
and the public how its research provides or can provide solutions to long-term
productivity issues.
PROGRAM GOALS AND
OBJECTIVES
The goal of this
Program is to establish and foster integrated long-term research on the effects
of forest management practices on long term soil productivity. Specific objectives for these first five
years include:
·
Conduct research on
fundamental mechanisms controlling forest productivity and potential
productivity as a basis for interim modeling efforts that predict the effects
of management over the long-term.
·
Establish and
follow replicated long-term applied research on benchmark soils or ecosystems
to study stand-level responses to cumulative management practices including
harvesting and site preparation, species selection, and other stand management
practices.
·
Link basic and
applied research on an Integrated Research Site as part of each series of
long-term applied studies. Use these
Integrated Research Sites as demonstration grounds to facilitate technology
transfer.
·
Provide federal
land managers with interim guidelines for effectively monitoring management
influences on long-term productivity.
APPROACH
This program
attempts to integrate basic and applied research and to use a focused
ecosystems approach to attack the problem at a regional level. The program will: emphasize a long-term research
and application perspective, generate new information on fundamental processes
of productivity, build partnerships between basic and applied researchers and
land managers, and link basic and applied research into a regional analysis of
the effects of management practices on long-term productivity.
Ecosystems are
usually described as an entire functional system encompassing a complex and
interacting assemblage of plants, animals, and microbes and their abiotic
environment, which acts on them and on which they act. An ecosystems approach stresses the
importance of complexity, interaction, and functional processes. A focused ecosystems approach is based on
three assumptions: (1)that you can not study one or two
members/factors/processes without considering the potential importance of all
members/factors/processes, (2)that because of inherent complexity, all
members/factors cannot be studied and accounted for, and (3) that a set of key
members/factors/processes can be identified with conceptual modeling.
Promote a long-term
perspective
We base our current
understanding of how various types of harvesting, site preparation, vegetation
control, and ameliorative measures affect forest productivity primarily on
short-term observations. Few convincing
studies on long-term effects of such practices are available for assessing
environmental impacts or for responding to possible legal challenges. Ideally, we would like to know how
management practices affect productivity over three or more rotations. Initial interpretations should be limited to
at least one full rotation.
Nearly all
continuing and past forestry research contributes in some manner to better
understanding of ecosystems and appropriate management of forests. However, most studies concerned with forest
productivity provide information on short-term effects on tree growth or other
processes related to productivity.
Long-term effects on productivity are implied from short-term results,
but actual effects are yet to be demonstrated.
Determining long-term effects of forest practices is a challenging need
not adequately served by current research efforts in the PNW Research Station
or elsewhere. In recognition of
short-term needs of land managers, this program will seek to improve our
ability to predict effects through conceptual and numerical modeling of
long-term processes.
Conduct research on
fundamental processes affecting long-term productivity
Basic forest
biology research faces an important dilemma: the need for increasing
specialization to understand complex natural processes on one hand, and, on the
other, the need to prioritize research and synthesize fragmented
information. Our approach is to develop
a broad-based conceptual model of long-term ecosystem productivity that will
identify key deficiencies in current knowledge and serve as a framework for
integration. A committee of scientists
from around the country will be assembled to build this model, develop a broad
consensus, and to determine research priorities.
Research will test
general assumptions in, and hypotheses generated by, the conceptual model. This research will be carried out in natural
and manipulated forest ecosystems and is designed to develop new information of
regional or national scope. We agree
with the DeBell report that due to the complex nature of forest ecosystems,
research should focus first on soil productivity as measured by growth of
dominant vegetation. We recognize,
however, that we need a multi-disciplinary approach to account for complex
interactions within the ecosystem.
Combining both perspectives results in a focused ecosystems
approach. Further, our in-depth
productivity research could attract concurrent study on other important issues
such as species diversity, global warming, and forest-atmosphere interactions.
Establish
partnerships to carry out applied research
Establish
partnerships between researchers and land managers to carry out applied
research on benchmark soils of Alaska, Oregon, and Washington. Working closely with land management
agencies and other land owners, we will establish long-term applied studies
designed to test the effects of management practices on long-term
productivity. A set of administrative
studies will be established on large plots in each of about six important
benchmark soils or ecosystems.
Together, these studies will make up a well-designed regional research
study that will emphasize those practices
which either alone or in combination with others are thought to have a long-term
influence on tree growth. Studies will
focus on the ability of the land to return to a desired state following
disturbance or to sustain improvements in site productivity gained from
individual or combinations of practices.
Common protocols and quality control measures will be required to insure
data quality and comparability.
Link basic and
applied research
One site from each
set of applied studies will be selected for more intensive basic and applied
research and designated an "Integrated Research Site." Our goal is to exchange ideas and
information among basic researchers, applied researchers, and land
managers. To do this, we will encourage
formation of teams of scientists and managers throughout Oregon, Washington,
and Alaska to work on Integrated Research Sites and associated applied
studies. Each team will formulate a
conceptual model of long-term productivity that is specific to the ecosystem
studied. These models will help focus
and prioritize research on the Integrated Research Sites and associated applied
studies, and help integrate designs and results. Integrated Research Sites form a critical physical and
intellectual link between the basic and applied programs. Multi-disciplinary research on Integrated
Research Sites will be designed, in part, to study mechanisms that lead to
responses obtained on the associated broader series of applied studies. Technology transfer of both short-term and
long-term research results will occur in the form of team interaction,
published articles, timely workshops, and newsletters.
Link research and
monitoring
This program will
provide land managers with guidelines for effectively monitoring management
influences on long-term productivity.
Guidelines will include protocols and quality control measures that will
enable monitoring systems to feed into a regional database on long-term
productivity. Local research and
monitoring will be linked in a regional data base to allow a more powerful
analysis of management practices and synthesis of research results. This database will be a valuable foundation
for modeling efforts and economic analyses of changing demands for resources.
ORGANIZATION AND
ADMINISTRATION
The program will
consist of two administrative functions: basic and applied research. Each be chaired by a Program Leader. Program Leadership will be a special
assignment made by the Station Director.
Program Leaders will remain housed in their respective work units,
reporting to the Director's office on matters relating to the Program, and to
their Project Leader for personnel matters and research conducted by the
individual which falls under the work unit mission. During the planning stage of the program, the Program Leaders
will report to the Assistant Director for Planning and Application (P&A AD)
for overall guidance and interaction with other PNW Research Station
efforts. The P&A AD will supervise
the performance of the Program Leaders for the work related to the program.
The integrated
research sites will be individually administered by local scientists, with
overall coordination divided between the two leaders. Research activities of work units which contribute to obtaining
the goals of this Program are covered under the respective unit's work unit
description and problem analyses.
Basic Research: The Program Leader will require a
scientist (Post-doc) and a technician to support personal and program
research. A science board composed of
3-4 scientists (FS and university nationwide), the P&A AD, Project Leader
for RWU 4356 and Program Leader for applied research will assist in narrowing
down the research issues and studies to be considered, advise on appropriate
funding strategies, facilitate a peer review process for study proposals, and
help develop broad-based support for the program. The Program Leader for basic research will then organize the
scientific talent needed for each research issue to define hypotheses and set
studies in motion. The Program Leader
will coordinate this research with similar efforts nationally and internationally.
Applied Research: The Program Leader for applied research
will require a programmer analyst to develop integrated database and supporting
software. A coordinating committee will
act in a similar capacity to the basic science board and will be composed of
the P&A AD, the Program Leader for basic research, scientists, and
representatives of Region 6, BLM, and industry. The Program Leader will gain a loose consensus at the
practitioner level on research needs and issues. The board will define scientific approaches to those needs and
issues. Scientists and practitioners
pooled for each topic will further refine the approach. Individual practitioners may serve on detail
to the Program Leader to gain expertise in study design and execution. These practitioners will then return to the
field to champion individual study sites.
The Program Leader will help to establish study sites and coordinate
research within and between applied studies and basic research program. We anticipate that the applied studies will
require support concerning study design, quality control, field methods, data
management, statistical analysis, and technology transfer.
Integrated Research
Sites: Each integrated
research site will be administered by a Lead Scientist from a PNW Project,
university or other organization.
Jointly the Lead Scientist and Program Leaders will be responsible for
gaining consensus on focus, and obtaining funding and cooperation from land
management agencies. The Lead Scientist
will make final decisions on site selections and study design within broad
program guidelines. The participation
of other scientists will be enlisted as needed. The Lead Scientist is responsible for ensuring integrity of
research conducted on these sites.
Participating scientists and managers will hold an annual workshop for
each site to develop consensus on research focus, review individual study
plans, and gain support for the program, both politically and financially.
Policy Board: This
group will consist of top line officers of participating agencies and
organizations. Its purpose will be to
keep top leadership informed and excited about program development and results,
and to provide management direction to the Long-Term Site Productivity Program.

PROGRAM DURATION
AND COST
The PNW long-term productivity
program will phase-in during FY 1989, be fully operational in FY 1990. This charter will cover Program activities
through FY 1995. The program will be
reviewed annually and may be revised as needed. The total research appropriated funds directed towards solution
of long-term productivity problems will be approximately $2 MM annually. The appropriated funds will approach $ 500 M
by the end of FY 1990. Establishment
and maintenance of administrative studies and Integrated Research Sites will be
largely supported by participating management agencies, who may also contribute
to research efforts directly or indirectly.
IMPACT ON CURRENT
PROGRAMS
PNW Research
Station intends to re-direct some research effort within the Station towards
program goals. Because we anticipate
that most program funds will be "new" money, from increase-list,
priority research program funding, and outside partners, we expect only
positive impacts on PNW work unit funding.
Research by PNW scientists supported by the program will be covered
under their work unit descriptions and problem analyses. Credit for attainment will stay with the
primary author's work unit. Other
long-term productivity research that is not included within the Station's
program will continue under existing project problem analyses and funding. The Program will also develop a reporting
mechanism for Program outputs. There
will be increased workloads for those Forests and Districts participating in
the applied research program to install sites, apply treatments, and maintain
sites. The work will augment and
enhance monitoring designs established in the Forest Plans.
COORDINATION WITH

ENVIRONMENTAL
IMPACTS
Environmental
analyses of forest management activities will be aided by program
research. By the very nature of the subject,
the environmental consequences of individual and collective activities on
research sites will not be known. Some
of the treatments and on the ground activities will be typical of standard
practices and will be covered by the environmental analyses conducted by the
local management agency. Lead
scientists will assist in the environmental analyses for research requiring
adverse treatments unfamiliar to the participating office.
