The "Terrain Stability and Forest Management in the Interior of British Columbia" workshop, held in Nelson on May 23-25, 2001, was the first conference on landslides, terrain stability, and related forest management issues to be held in the British Columbia Interior. The purpose of the workshop was to bring together research scientists, engineers, and foresters who have been dealing with this subject since the introduction of the Forest Practices Code
in 1995. An important objective was to present the results of several research projects on landslides and terrain stability, which were nearing completion
under the 5-year period of Forest Renewal British Columbia research funding that began in 1996.

The Forestry Continuing Studies Network and the B.C. Ministry of Forests, Nelson Forest Region organized the workshop. The Association of Professional Engineers and Geoscientists of British Columbia, Division of Engineers and Geoscientists in the Forest Sector (DEGIFS), and the Arrow Innovative Forest Practices Agreement (IFPA) sponsored the event. Twenty-three oral presentations and 14 posters were presented at the workshop, covering a range of landslide research, geotechnical engineering, and applied forestry topics.

On two field trips, participants visited sites of interest in the West Kootenays. Approximately 200 people attended the workshop.

These proceedings include 16 of the papers presented at the workshop. These papers have been peer-reviewed and revised over the 12 months since
the workshop. The digital version of the proceedings, to be distributed on compact disc and on the Internet, also features appendices containing other
products of the workshop, including abstracts, notes and graphics attached to the abstracts, slide presentations, and field trip guides. Appendix 2 has not
been reviewed or edited.

Note regarding British Columbia government ministries and the Forest Practices Code: As these proceedings go to press, the British Columbia government
has announced major changes to the Forest Practices Code and to government ministries, forest regions, and districts. Some papers in these proceedings refer to government ministries and their geographic entities, and to regulations or guidebooks of the Forest Practices Code. All such references are current as of the date of the workshop, May 2001.
