PREFACE
The Working
Group on Criteria and Indicators for the Conservation and
Sustainable Management of Temperate and Boreal Forests ("Montreal
Process") was formed in Geneva in June 1994 to advance the
development of internationally agreed criteria and indicators
for the conservation and sustainable management of temperate
and boreal forests at the national level. Participants in
the Working Group included Australia, Canada, Chile, China,
Japan, the Republic of Korea, Mexico, New Zealand, the Russian
Federation and the United States of America, which together
represent 90 percent of the world's temperate and boreal
forests. Several international organizations, non-governmental
organizations and other countries also participated in meetings
of the Working Group.
In February
1995 in Santiago, Chile, the above countries endorsed a
comprehensive set of criteria and indicators for forest
conservation and sustainable management for use by their
respective policy-makers. This document presents these criteria
and indicators, together with the statement of endorsement
known as the "Santiago Declaration".

"SANTIAGO
DECLARATION" -- STATEMENT ON CRITERIA AND INDICATORS FOR THE
CONSERVATION AND SUSTAINABLE MANAGEMENT OF TEMPERATE AND BOREAL
FORESTS
The Governments
of Australia, Canada, Chile, China, Japan, Mexico, New Zealand,
the Republic of Korea, the Russian Federation and the United
States of America, which are participating in the Working
Group on Criteria and Indicators for the Conservation and
Sustainable Management of Temperate and Boreal Forests ("Montreal
Process") and whose countries contain a significant portion
of the world's temperate and boreal forests:
Recognizing
that the sustainable management of all types of forests, including
temperate and boreal forests, is an important step to implementing
the Statement of Forest Principles and Agenda 21, adopted
by the United Nations Conference on Environment and Development
(UNCED), held in Rio de Janeiro in June 1992, and is relevant
to the United Nations conventions on biological diversity,
climate change and desertification,
Also recognizing
the value of having an internationally accepted understanding
of what constitutes sustainable management of temperate and
boreal forests, and the value of agreed criteria and indicators
for sustainable forest management in advancing such an understanding,
Mindful
that the application of agreed criteria and indicators will
need to take account of the wide differences among States
regarding the characteristics of their forests, including
planted and other forests, land ownership, population, economic
development, scientific and technological capacity, and social
and political structure,
Taking note
of other international initiatives regarding the development
of criteria and indicators for sustainable forest management,
Affirming
their commitment to the conservation and sustainable management
of their respective forests, and
Having undertaken
substantive discussions to develop agreed criteria and indicators
for the conservation and sustainable management of temperate
and boreal forests,
Endorse
the non-legally binding Criteria and Indicators for the Conservation
and Sustainable Management of Temperate and Boreal Forests
annexed to this Statement as guidelines for use by their respective
policy-makers;
Encourage
other States which have temperate and boreal forests to consider
the endorsement and use of these criteria and indicators;
Note
the ongoing nature of the discussion on these criteria and
indicators and the need to update the annex as new technical
and scientific information and data become available and assessment
capability increases; and
Request
the Government of Chile, on behalf of the above States, to
present this Statement, together with its annex, to the FAO
Meeting of Ministers Responsible for Forestry, to be held
in Rome, March 16-17, 1995, and the third session of the United
Nations Commission on Sustainable Development, to be held
in New York, April 11-28, 1995.

SECTION
1 -- INTRODUCTION
| 1.0 |
Forests
are essential to the long-term well being of local populations,
national economies, and the earth's biosphere as a whole.
In adopting the statement of Forest Principles and Chapter
11 of Agenda 21, the 1992 UN Conference on Environment
and Development (UNCED) recognized the importance of
sustainably managing all types of forests in order to
meet the needs of present and future generations.
|
| 1.1 |
The
development of criteria and indicators for the conservation
and sustainable management of temperate and boreal forests
is an important step in implementing the UNCED Forest
Principles and Agenda 21, and is relevant to the UN
conventions on biodiversity, climate change and desertification.
It is also an important step to furthering the joint
commitment made by tropical timber consumer countries
in January 1994 to maintain, or achieve by the year
2000, the sustainable management of their respective
forests. |
| 1.2 |
The
criteria and indicators listed under Sections 3 and
4 apply broadly to temperate and boreal forests. They
are intended to provide a common understanding of what
is meant by sustainable forest management. They also
provide a common framework for describing, assessing
and evaluating a country's progress toward sustainability
at the national level. They are not intended to assess
directly sustainability at the forest management unit
level. As such, the criteria and indicators should help
provide an international reference for policy-makers
in the formulation of national policies and a basis
for international cooperation aimed at supporting sustainable
forest management. Internationally agreed criteria and
indicators could also help clarify ongoing dialogues
related to international trade in products from sustainably
managed forests. |
| 1.3 |
The
approach to forest management reflected in the criteria
and indicators is the management of forests as ecosystems.
Taken together, the set of criteria and indicators suggests
an implicit definition of the conservation and sustainable
management of forest ecosystems at the country level.
It is recognized that no single criterion or indicator
is alone an indication of sustainability. Rather, individual
criteria and indicators should be considered in the
context of other criteria and indicators. |
| 1.4 |
It
should be emphasized that an informed, aware and participatory
public is indispensable to promoting the sustainable
management of forests. In addition to providing a common
understanding of what is meant by sustainable forest
management in the temperate and boreal region, the criteria
and indicators should be useful in improving the quality
of information available not only to decision-makers
but also to the general public. This in turn should
better inform the policy debate at national and international
levels. |
| 1.5 |
Each
country is unique in terms of the quantity, quality,
characteristics and descriptions of its forests. Countries
also differ in terms of forest conditions relative to
national population, such as the amount of forest per
capita, the amount reforested annually per capita or
the annual forest growth per capita. National circumstances
further differ with respect to stages of economic development,
land ownership patterns, population patterns, forms
of social and political organization, and expectations
of how forests should contribute or relate to society.
|
| 1.6 |
Given
the wide differences in natural and social conditions
among countries, the specific application and monitoring
of the criteria and indicators, as well as the capacity
to apply them, will vary from country to country based
on national circumstances. It is anticipated that individual
countries would develop specific measurement schemes
appropriate to national conditions to address how data
would be gathered. Qualitative terms such as "significant"
or "low," which are used as indicator descriptors in
some cases, would also be defined based on national
conditions. Despite these differences, efforts should
be made to harmonize the approaches of countries to
measuring and reporting on indicators. |
| 1.7 |
Changes
in the status of forests and related conditions over
time, and the direction of the change, are relevant
to assessing sustainability. Therefore, indicators should
be understood to have a temporal dimension. This means
they will need to be assessed as trends (e.g., at points
in time) or with an historical perspective to establish
trends. The monitoring of changes in indicators will
be essential to evaluating whether and how progress
is being made toward the sustainability of forest management
at the national level. |
| 1.8 |
While
it may be desirable to have quantitative indicators
that are readily measured or for which measurements
already exist, such indicators alone will not be sufficient
to indicate the sustainability of forest management.
Some important indicators may involve the gathering
of new or additional data, a new program of systematic
sampling or even basic research. Furthermore, some indicators
of a given criterion may not be quantifiable. In cases
where there are no reasonable quantitative measures
for indicators, qualitative or descriptive indicators
are important. These may require subjective judgments
as to what constitutes effective, adequate or appropriate
national conditions, or trends in conditions, with respect
to the indicator. |
| 1.9 |
Concepts
of forest management evolve over time based on scientific
knowledge of how forest ecosystems function and respond
to human interventions, as well as in response to changing
public demands for forest products and services. The
criteria and indicators will need to be reviewed and
refined on an on-going basis to reflect new research,
advances in technology, increased capability to measure
indicators, and an improved understanding of what constitutes
appropriate indicators of sustainable forest management.

SECTION
4 -- CRITERIA AND INDICATORS FOR THE CONSERVATION AND SUSTAINABLE
MANAGEMENT OF TEMPERATE AND BOREAL FORESTS CRITERION 7
4.0 Criterion
7 and associated indicators relate to the overall policy framework

Appendix
-- Explanatory Notes on Selected Criteria and Indicators
The following
explanatory notes provide a further explanation or "rationale"
as to what is meant by selected criteria and indicators
and why they are considered important to assessing forest
conservation and sustainable management. As noted in paragraph
1.3, "no single criterion or indicator is alone an indication
of sustainability. Rather, individual criteria and indicators
should be considered in the context of other criteria and
indicators."
3.1 --
Criterion 1: Conservation of biological diversity
The ultimate
objective of the conservation of biological diversity is
the survival of species and the genetic variability within
those species. Viable breeding populations of species and
their natural genetic variation are part of interdependent
physical and biological systems or processes - communities
or ecosystems. The condition and distribution of forest
communities are important to fundamental ecological processes
and systems and the future of biological diversity associated
with forests.
Ecosystem diversity
-
Ecological
processes and viable populations of species that are characteristic
of forest ecosystems are usually dependent on a contiguous
ecosystem or ecosystems of a certain minimum size. Genetic
diversity within a species population depends on the maintenance
of subpopulations and the existence of forest ecosystems
that cover a large part of their natural range. Forests
may constitute all or a part of the habitat necessary
to the survival of a species.
-
Ecological
processes and the species associated with those processes,
within any forest ecosystem or forest type, are associated
with vegetative structures (age of the vegetation, its
diameter, and height) and successional stages (variable
species of vegetation).
-
The
amount of a forest ecosystem reserved in some form of
protected area is a measure of the priority being placed
on maintaining representative areas of that forest ecosystem
by society.
-
The
fragmentation of a forest type into small pieces may disrupt
some ecological processes and availability of habitat.
Such fragments of forest may be too small to maintain
viable breeding populations of species. Distances between
forest fragments can interfere with pollination, seed
dispersal, and wildlife movement between patches of forest
and breeding.
-
Ultimately,
excessive fragmentation can contribute to the loss of
plant and animal species that are unable to adapt to these
conditions. In areas converted in the past to agricultural
purposes, remnant forest fragments of the original forest
cover may provide refuges for many, although not all,
components of the original diversity.
Species diversity
- Surveys
of species numbers are necessary in order to estimate biological
diversity.
- Ecological
processes and the species associated with those processes,
within any forest type, may vary according to the extent,
condition, or fragmentation of that forest type.
Genetic diversity
-
Forest
dependent species with low population levels or significantly
reduced range run the risk of losing important genetic
traits (alleles) from their gene pools. In the case of
species with a dispersed natural range, this can happen
at the level of locally adapted subpopulations (provenances),
resulting in a reduced ability by species to adapt to
environmental changes.
-
Monitoring
the population levels of species representative of identified
habitats, or ecosystems, across their range provides an
indicator of the ability of those habitats to support
other species, and subpopulations of those species, dependant
on similar habitat.
3.2 -- Criterion 2:
Maintenance of productive capacity of forest ecosystem
-
In
many countries, traditional calculation of potential production
of timber products is based on the forest area available
for the production of commercial forest products. In those
countries, forest lands are not available for timber harvesting
if they do not meet minimal acceptable regeneration standards,
minimal acceptable economic growing rates, or accessibility.
High spiritual, recreational, scientific, or educational
values may also be deemed a higher priority than commodity
production. Comparison of net forest land available for
timber production to total forest land will provide a
measure of the suitability or availability of the forests
for commercial forest production to meet society's demands
for wood products. In reference to managed forests, some
feel this is also an indicator of forest areas whose ecological
or genetic character may be different.
-
Measurements
of merchantable and non-merchantable growing stock provides
an indication of timber supply opportunities.
-
Planted
forests can be an important source of forest products
and can replace or augment the use of natural forests
for the production of wood and non-wood forest products.
In other countries, natural forest management is used
as an alternative to planted forests. The area of forest
plantations provides one measure of forest management
efficiency and reduced future dependence on natural forests
for the production of commercial forest products. In addition,
some feel this is also an indication of forest areas whose
ecological and genetic character may be different. However,
many planted forests have been established to reclaim
degraded lands where the ecological and genetic character
of the original forest had been lost.
-
Monitoring
the volume of wood and non-wood forest products annually
removed relative to the amount which could be removed
sustainably provides an indication of a forest's ability
to provide a continuing supply of forest products and
economic and forest management opportunities.
3.3 -- Criterion 3:
Maintenance of forest ecosystem health and vitality
-
People
have multiple effects on forest ecosystems. Human impacts
include land conversion, harvesting, species introductions,
suppression of natural fire cycles and floods, and the
introduction of nonnative species especially pathogens.
These in turn influence ecological processes and ultimately
forest dependent plant and animal species.
-
Air
pollutants are suspected to have a significant cumulative
impact on forest ecosystems by affecting regeneration,
productivity, and species composition. Correlating forest
inventory and health statistics with air pollution data
will provide more information on the effects of these
pollutants. Increased ultraviolet radiation, caused by
changes in the earth's atmosphere, also has been shown
to damage plants.
-
The
monitoring of forest structure or macro species such as
vertebrates (criterion 1) will tend to detect changes
in ecological processes decades after they have begun.
Monitoring very short-lived species associated with specific
ecological processes such as decomposition and nutrient
cycling provides a more immediate indication of changes
in ecological processes with potential importance to forests.
3.4 -- Criterion 4:
Conservation and maintenance of soil and water resources
-
The
soil resource is a basic component of all terrestrial
ecosystems. The loss of soil will influence the vitality
and species composition of forest ecosystems. Extensive
areas of soil erosion can have a major effect on aquatic
ecosystems associated with forests, recreational opportunities,
potable water supplies and the life span of river infrastructure
such as dams.
-
This
indicator provides a measure of forest land allocated
primarily for the protection of valuable environmental
amenities associated with clean air, water, soil, flood
and avalanche protection, etc. (public health and safety
functions).
-
Forests
are an important part of the earth's hydrological cycles.
They are particularly important in the regulation of surface
and ground water flow. Changes in historic stream flow
and the timing of flow, resulting in flooding and/or dewatered
streams, can reflect on the health of aquatic ecosystems
and the management and conservation of associated forest
areas and downstream agriculture areas.
-
Soil
organic matter is important for water retention, carbon
storage, and soil organisms and is an indication of soil
nutrient status. Changes in soilorganic matter can affect
the vitality of forest ecosystems through diminished regeneration
capacity of trees, lower growth rates, and changes inspecies
composition.
-
Nutrient
and water availability to forest vegetation is dependent
on the physical ability of roots to grow and access nutrients,
water and oxygen from the soil. This in turn is dependent
on soil texture and structure. Subsurface hydrology can
also be affected by soil compaction resulting from extensive
human activities.
-
This
is frequently a measure of benthos populations, e.g. organisms
that live at the bottom of water bodies. Benthos fauna
are sensitive to a variety of possible changes in aquatic
ecosystems such as silt, oxygen levels, and temperature.
These changes may be the result of changes in upland forest
areas.
-
Monitoring
water quality over large areas serves as an initial indication
that activities inside or outside a forest area may be
affecting ecosystem health.
3.5 -- Criterion 5:
Maintenance of forest contribution to global carbon cycles
-
The
accumulation of biomass as living vegetation, debris,
peat, and soil carbon (carbon pool) is an important forest
function in regulating atmospheric carbon. The production
rate of biomass is also a measure of forest health and
vitality.
-
The
ecological and sustainable management of production forests
and the long lasting use of forest products can be a factor
in controlling the amount of carbon entering the world's
atmosphere.
