The two documents listed below provide a conceptual overview of the core LANDIS-II model and provide the User Guide for using the LANDIS-II core. Information about individual ecological processes can be found in the individual extension users guides and the peer-reviewed literature. See the Extensions page for documentation for individual extensions. These on-line User Guides will be the most up-to-date.

How to Install LANDIS-II v6.2

LANDIS-II v6.2.1 was released in June 2017.  Previous versions are not available and are not supported.  The Windows version is only for 64-bit computers, e.g., Windows Vista, 7, 8, 10.   LANDIS-II also runs under Mac OSX and Linux, although the installation is more complex.  See notes on the Users Bulletin Board.
Next, we recommend that you install these base extensions.  They are simple to use and provide a great introduction:  
Additional extensions require separate downloads.  Each of these extensions has its own web site with installer that is accessible from the Extensions Page.   After you install LANDIS-II, you will find Documentation, Sample Files, and an Uninstaller on your programs menu (Start -> Programs -> Landis-II -> 6.2).
