Ripple: A Coho Salmon Population Model
Ripple is a digital terrain-based model for defining the limiting factors in coho salmon populations in upland watersheds. Ripple is the result of a long-term collaboration with Stillwater Sciences (an NCED partner). As a first step in applying our terrain-based approach to a specific population, Ripple uses topographic data to calculate habitat and a population dynamics model to identify habitat limitations.
It is specifically designed:
1. To be used where data are limited;
2. To serve as a guide to field investigations;
3. To guide management decisions; and
4. To refine hypotheses for further theoretical advances.
Ripple only works under ESRI’s ArcGIS Desktop. You must have an operating copy of either ArcGIS 8.3 or 9.2 to run Ripple. There are separate project files for each version. OS: Windows XP or
