Sustainable development is a term reflecting human, societal, and environme
ntal values and in order to determine progress toward this goal: it is nece
ssary to identify and define these values, and for governments or other ins
titutions to establish the means to assess progress. Canada is directly inv
olved in national and international processes to assess the sustainability
of forest management processes using Criteria and Indicators. These consist
of a group of broad core values (Criteria) and are supported by an number
of measures (Indicators) to assess status or progress toward the realizatio
n of these values. Measuring and monitoring indicators is necessary to demo
nstrate progress toward sustainable development nationally and internationa
lly. The criteria that have been identified include the traditional concept
s of timber values, and include economics, environmental, social values, an
d national infrastructures. Each criterion is supported by a number of indi
cators to track progress. Countries in the international process also colla
borate on defining terms, methods of reporting, and improving and enhancing
indicators. C&I facilitate international reporting and provide a framework
for international agreements while reflecting national differences in char
acteristics and descriptions of forests. The reporting process has stimulat
ed the emergence of forest management issues that will influence forest sci
ence and forest ecosystem management in the future. For Canada, these inclu
de the development of a national system of forest ecosystem inventory, and
ecological classification, the interpretation of the range of historic vari
ation, and the adequacy and applicability of data sources.
