International Workshop for Certified Forest Products and Sustainable Forestry

International Workshop Overview

International Workshop for Certified Forest Products and Sustainable Forestry
Co-sponsored by IUFRO Division 5.12, Chinese Academy of Forestry, and USDA Forest Service

The International Union of Forest Research Organizations (IUFRO) Division 5.12 Sustainable Utilization of Forest Products Research Group is sponsoring an international workshop on certified forest products, life cycle assessment, ecosystem services markets and sustainable forest management. This workshop will discuss the positive roles that certified forest products, life cycle assessment and sustainably managed forests play in improving the lives of people through economic, environmental, ecological and social benefits of forests. Individual sessions will provide a forum for researchers and forest owners and managers who are interested in forest certification, life cycle assessment, economic contribution of forest products, ecosystem services and markets and sustainable forestry.

International Workshop for Certified Forest Products and Sustainable Forestry – Themes


Session 1. Forest Product Certification
Forest certification and forest sustainability are vital environmental and natural resource management matters. Forest certification is an eco-labeling scheme that recognizes forest products which originate from sustainably-managed forests but is not based on evaluating the end-product itself. There is a growing demand for a labeling program to identify wood produced under sustainable forestry principles. Life-cycle assessment (LCA) can be used for the evaluation of these principles for end products (e.g. wood as a building material). LCA can measure multiple environmental and social impacts ascribed to a product in support of a comprehensive and transparent labeling program. Workshop topic sessions include ecolabels such as environmental product declarations and environmental building declarations based on LCA and the role of LCA in forest certification in quantifying impacts.

China Garden Session 2. Ecosystem Services and Markets
Emerging markets for ecosystem services presents some new opportunities for forest landowners and managers. There is increasing recognition of the importance of ecosystem services markets and the values these services provide to landowners and managers. These emerging markets include carbon credits, water quality and quantity, wetland mitigation, species conservation banking and a number of habitats of value for forest landowners and managers. This session will assess emerging global themes for sustainable utilization of certified forest products including the process for bundling or combining markets to increase forestland value.

Session 3. Life Cycle Analysis
Life-cycle analysis assesses the potential impacts that resource extraction, production, distribution, use, and services have on the environment. This session covers the life-cycle assessment (LCA) on forest products and operations from cradle-to-grave, and links the carbon accounting metrics to LCA for sustainable design of wood systems including buildings and bridges and how green building standards and code incorporate LCA for accreditation and compliance. Topic sessions include, but not limited to, LCA for wood products, forest management, bioenergy, and emerging products from forest industry.

Session 4. Sustainable Forest Management and Certified Forestry
Sustainable forest management integrates ecological, economic and social considerations. These include managing, growing and harvesting forest products with the conservation of soil, water, wildlife habitat and socioeconomic benefits to meet society needs and the sustainability of forests to produce wood and other forest products. This session will broadly address emerging global themes for forest products and the role of forest certification to integrate wood production into forest management for multiple objectives. This session will specifically assess different aspects of forest certification including impacts on forest management and timber markets; quality of certification audits; governance and authority of certification schemes; partnerships between lands and public lands. The session provides a forum for researchers who study forest certification, economic and social benefits of certified forest products within the broad context of sustainable forest management.

Fundamentals and Best Practices for Forest Inventories

Co-sponsored by:

8:00Building Blocks of Sound Inventory Design

  1. What is a working forest inventory? The evolution over 30 years from strata averages and yield tables to individual stand structures within strata.
  2. Why you should be cruising for inventory versus harvest. Your cruising objective is to capture silvicultural growth capacity and setup the ability to re-merchandize as markets change.

8:30Sample Designs – Strata

  1. Stratifying the whole forest – What are the right classifications and levels of strata?
  2. Breaking the strata into unique stand polygons – Why we need unique stand identification.
  3. Sampling stands within each strata for cruising – Getting the right distribution, intensity and frequency of sampling and working with riparian buffers and setasides.


10:20Sample Design – Plots

  1. Distributing your plots across the entire stand – Why this makes a difference.
  2. Including small tree frequencies to define density.
  3. How large tree frequencies define silvicultural options and asset values.
  4. Defining clumpiness with systematic spatial plot patterns to quantify the impact on yield capacity.
  5. Determining the right plot frequency and distribution within each stand.


1:00Sample Design – Trees

  1. Sampling all trees of all species and sizes within each stand makes a difference.
  2. Applying a combination of prism-sweep and fixed area plot designs for sampling.
  3.  A. Tally frequencies by species and size class, never by species alone.
     B. When and why to record tree condition and vigor class in cruise design.
     C. Methods for selecting large trees height samples – why this makes a difference.
     D. Estimating live crown length and percent defect in large trees.
     E. When and how to measure taper.
     F. When and why to measure age.

  4. How to use a 1/20th acre fixed area circular plot for standing dead trees.
  5. Sampling down woody material using a minimum 100-foot transect line.


2:20Cruise Compilation Methods

  1. Compiling each stand cruise versus compiling by strata – within and between stands.
  2. Height estimation methods – why tree heights vary with silviculture.

3:30Expanding the Cruise to Un-sampled Stands

  1. Assigning a stand structure to un-sampled stands from an average tree list generated from sampled stands – when and why these methods are important to understand and use.
  2. Do’s and don’ts of cruise expansions – methods, timing, frequency and assumptions.

4:15Year-end Updates and Reporting – Getting the Sequence and Components Right

  1. Incorporating all new harvest units, deletions, acquisitions and boundary adjustments in a GIS stand polygon layer.
  2. Updating the GIS road network and road class buffer widths.
  3. Updating the GIS stream courses and riparian buffer widths.
  4. Updating all administrative, silvicultural and operational costs.
  5. Running reports for year-end harvest volume and value reports.
  6. Growing stands for one year from the previous year for annual growth reporting.
  7. Updating the inventory with all new cruises from all sampled stands within current year – identifying the actual impact of new information.
  8. Producing forest-wide reports of new current standing forest inventory.
