RILSIM

RILSIM, the “Reduced-Impact Logging SIMulator”, is financial modeling software developed as a service to the international forestry community. RILSIM has been designed to permit users to rapidly estimate the costs and net revenue associated with logging operations in order to compare short-term financial costs and returns expected from reduced-impact logging with those expected from conventional logging under identical local site conditions. The purpose of the software is to help users learn about reduced-impact logging and its potential financial advantages as compared to conventional logging.

How to Obtain RILSIM

RILSIM is provided free of charge to anyone, anywhere in the world. The current version is available only as a download; we no longer have financial support to provide the software on CD-ROM with a printed user's guide.
