Microcomputer scientific software series 8: The SYCOOR users manual. Forest Service general technical report

The manual describes how to use SYCOOR, an interactive Macintosh program written in BASIC for computing and adjusting synecological coordinates. Site synecological coordinates are indices of moisture, nutrients, heat, and light computed from lists of plant species present at the site. Graphs of a species' distribution in moisture-nutrient and heat-light space are also displayed by the program.
