Documentation, Video and Computer Programs

For more information about SYLVER go to Publications and References, and also via:

• The SYLVER System - Forest Management Simulator - a 10-minute overview of SYLVER on VHS video. Copies can be borrowed by contacting Shelley Grout;

• SYLVER demo (SYLDEMO) - a computer generated presentation that demonstrates the importance of incorporating volume, quality and value criteria into silvicultural decisions. Currently it focuses on the operation of SYLVER to assess wood volume and value, juvenile and mature wood characteristics, and pruning by means of images, animated sequences, and supporting text. A version of this program has been modified for direct viewing at the SYLDEMO Website;

• Fred's Forest - an interactive forestry management computer game and training tool designed to demonstrate the capabilities of SYLVER. Players manage a woodlot for profit by selecting the regeneration method, establishment density, thinning and pruning regimes, and harvest age. It displays each treatment, and the subsequent development of the stand, with 3-dimensional graphics, followed by a score (i.e. net discounted profit). Fred's Forest is billed as a game, but its real purpose is to show the public, and kids in particular, that trees really grow and that we can manage them for our benefit. A new multimedia CD-ROM version 3.1, which operates in both MS Windows and Macintosh environments, is now available.  See the Fred's Forest webpage for more details.

Workshops/Training

SYLVER training and concepts are covered in:

• Module III of the Forest Management Institute of British Columbia;
• workshops offered at regional headquarters and in combination with other courses and meetings;
• TIPSY training courses offered through the Forestry Continuing Studies Network;
• An Introduction to Growth and Yield Computer Based Training (CBT) - a computer based training program for learning some basic growth and yield concepts and economic assumptions included in SYLVER.

Recent Applications Using SYLVER
