The LANDIS-II Forest Landscape Simulation Model

LANDIS-II simulates forest succession, disturbance (including fire, wind, harvesting, insects), climate change, and seed dispersal across large (typically 10,000 - 20,000,000 ha) landscapes. LANDIS-II tracks the spatial distribution of discrete tree and shrub species and has flexible spatial and temporal resolutions. Learn more about our research and see our publications list.

LANDIS-II advances forest modeling in many respects. Most significantly, LANDIS-II, 1) is completely open-source at all levels with extensive documentation, 2) has a large library of ecological processes to choose from, including many explicitly designed to track landscape carbon dynamics, 3) has flexible time steps for every ecological process, 4) uses an advanced architecture that allows rapid model development and easy distribution and installation of model components. We are also very proud of our large and active community of users and developers.

LANDIS-II manages and executes discrete extensions (modules or plug-ins). Each ecological process is programmed as an independent extension that interacts with the landscape through an explicit interface with the core LANDIS-II program. The user specifies which extensions will be used to best simulate the forest dynamics of interest. LANDIS-II allows scientists to easily develop and share their own extensions.

The original LANDIS (LANdscape DIsturbance and Succession) model was developed by Drs. David Mladenoff, Hong He, and others.  LANDIS-II was developed at the Forest Landscape Ecology Laboratory at the University of Wisconsin-Madison, the USFS Northern Research Station, the Dynamic Ecosystems and Landscapes Lab at Portland State University, and Harvard Forest.

Recent Announcements

  • Base Extensions Updated The Age-only Succession extension has been updated to version 4.0.  Version 4 allows for dynamic probability of establishment over time.The other base extensions (disturbance and output) were also updated so that their example files are compatible with Age-only Succession v4.  There were no other substantial changes to the base disturbance and output extensions.

  • Proposal to Modify Biomass Extensions A proposal (attached) has been approved by the Technical Advisory Committee to modify the Biomass Extensions.  The revised extensions will be released in mid-July 2014.

  • New! The LANDIS-II Exercise Book! We have just published our definitive guide to using LANDIS-II, 'Forecasting Forested Landscapes: An Introduction to LANDIS-II with Exercises'  The book provides a broad introduction to forest landscape modeling generally, LANDIS-II specifically, and it includes the same exercises used in our regular training sessions (see above).The book is on sale at:  All proceeds go to The LANDIS-II Foundation to maintain the model and supporting systems.

  • Harvard Forest Training We held our first LANDIS-II training session at Harvard Forest (HF) this week (4/8- 4/10).  The class was taught by Drs. Lucash (PSU), Duveneck (HF) and Thompson (HF). There were 10 attendees from U. VT, U. Maine, Harvard Forest, U. Montreal, UQAT (Canada), and Bournemouth U. (U.K.). The first two days were similar to past training sessions but the final day was devoted to our first four hour Century training workshop.  It went well!  Thanks to all the instructors and participants.

  • BFOLDS Released BFOLDS (Boreal FOrest Landscape Dynamics Simulator) Fire Regime Module v2.0 represents forest fire processes mechanistically in a spatially explicit manner. It simulates fire ignition, growth, and extinguishment based on input data of weather, forest composition, and terrain and scientific knowledge of Canadian Forest Fire Behavior Prediction System and Fire Weather Index system.For more information, installer, documentation, etc., see:
