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

  • New LANDIS-II succession extension: PnET-Succession Eric J. Gustafson, Northern Research Station, Rhinelander WI, USA Because LANDIS-II is being used to make projections under novel environmental conditions that have no empirically observed analog (e.g., climate change), it is becoming critical to strengthen the links between the fundamental drivers of tree cohort growth and competition (temperature, precipitation, CO2 concentration) within the process extensions of LANDIS-II.  A more mechanistic approach (PnET-Succession) to simulating growth within LANDIS-II was recently developed by De Bruijn et al. (2014) by embedding algorithms of the PnET-II stand-level ecophysiology model (Aber et al. 1995) within the Biomass Succession extension to more mechanistically simulate growth as a competition for light and water to support photosynthesis.  Where the Biomass ...

  • LANDIS-II v6.1 Released! Introducing LANDIS-II version 6.1! This latest version of the LANDIS-II core includes just a few minor changes requested by the user community. Please consult the release notes for details on the specific changes that were made. For those wishing to upgrade, we recommend uninstalling version 6.0 before upgrading to 6.1. Unfortunately this does also entail re-installing all of your extensions.LANDIS-II version 6.1 has been tested and found to be compatible with extensions than run under version 6.0, but if you run into any problems don't hesitate to let us know.

  • Third Edition of Forecasting Forested Landscape Now Available! We have just published the third edition of 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.

  • 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.
