I developed an AI (please note, AI stands for Artificial Intuition in this case) program for vegetation classification. I apologize for charging for this program, it cost $85.00 to those who have funds available. COENOS - an IBM PC program for the table technique of vegetation classification. Developed by Adolf Ceska & Hans Roemer. The table technique is a powerful method for analyzing vegetation data (see Chapter 9 in Mueller-Dombois, D. & H. Ellenberg. 1974. Aims and methods of vegetation ecology. John Wiley & Sons, New York). It was developed in Europe and is used there especially in the Zurich-Montpellier (or Braun-Blanquet) school of phytosociology. A well sorted vegetation table provides a clear insight into the structure of vegetation data; it displays both vegetation types and the species that typify them. The use of the table technique, however, requires an extensive apprenticeship. The manual sorting of vegetation tables is time consuming, relatively subjective, and feasible only for smaller data sets. COENOS enables the user to sort vegetation table in minutes. A simple iterative algorithm establishes an objective basis for the technique, and COENOS can analyze reasonably large data sets. COENOS is based on our earlier main frame program (Ceska, A. & H. Roemer, 1971. A computer program for identifying species-releve groups in v egetation studies. Vegetatio 23: 255-277). When the program was adapted for a micro-computer numerous features were added to make COENOS extremely user-friendly. COENOS has the following steps: Reading the data. The input is a sequential file of releves (plots), essentially transcripts of field records. Extraction of species/releve groups. Blocks of releves and the species which characterize them are extracted from the data. Ordination of species/releve groups. Species/releve groups are ordered using a two-way ordination technique and the result is displayed in a simplified table. Display of the final vegetation table. A full final table of releves and species is displayed on the screen. The user can rearrange the table by grabbing a column or a row and moving them on the screen. The full vegetation table provides an excellent insight into the structure of vegetation data. Results of COENOS are similar to TWINSPAN, but more graphic. COENOS is available for the IBM PC and compatible microcomputers (PC-DOS or MS-DOS 2.0 or higher) and the IBM PS/2 series. It supports all IBM compatible printers. COENOS version 3.01 can handle up to 1,000 releves and 650 species. COENOS is distributed by Dr. Adolf Ceska, P.O. Box 1761, Victoria, B.C., V8W 2Y1, Canada. Cost: US$85.00 E-mail: aceska@cue.bc.ca
