The LANDIS-II Landscape Change Model

The LANDIS-II forest landscape model simulates future forests (both trees and shrubs) at decadal to multi-century time scales and spatial scales spanning hundreds to millions of hectares. The model simulates change as a function of growth and succession and, optionally, as they are influenced by range of disturbances (e.g., fire, wind, insects), forest management, land use change. Climate and climate change affect processes throughout the model. LANDIS-II is highly customizable with dozens of libraries ('extensions') to choose from.

The LANDIS-II community is very active with 100s of users and developers worldwide. We welcome anyone to join the LANDIS-II community and to contribute. All model components are free and open-source. There are active bulletin boards for Users and Developers. And there are meetings and training held every year in various locations across the US and Canada.

To learn more about our research, see our publications list.

Some features of LANDIS-II:

Users can select from a large library of ecological and social processes.
Flexible time steps for every process.
Flexible spatial resolution and study area extent.
Designed for rapid development and easy distribution and installation of model components.
A large and active community of users and developers.
Completely open-source with extensive documentation.
Managed as a non-profit scientific and educational organization.

Recent Announcements

  • Training and Conference Coming Up - Register Soon! We are excited to announce our next training and conference on June 27-29, 2018 in beautiful and sunny Madison, Wisconsin. Attend either or both sessions.* Training will be on the 27th and 28th and includes two full days of hands-on training and a training guidebook. * The conference on the 29th will include presentations on recent updates and future plans for the LANDIS model.  There will also be break-out groups to discuss and plan for specific needs. These discussions are critical for determining the near term investments we collectively make in the LANDIS framework.  All events will happen at the Pyle Center on the UW Campus.  A block of hotel rooms ...

  • Core and Extension Release Day 2017! Dear All:We have been diligently updating many of our extensions and today is release day!Extension updates: updates range from major to minor.  The major effort was to make all Biomass extensions cross-compatible with Biomass, PnET, and NECN succession extensions.  Other updates including adding the Metadata Library to most extensions, allowing their use with the LANDVIZ tool:  The Core was also updated to 6.2.1, although this is a very cosmetic upgrade, changing some of the error messages to be more intuitive.We instituted a rigorous QAQC process for each.  However, as with all software, there's no doubt that ...

  • Next Training in August 2017 The LANDIS-II Foundation is hosting a training workshop this summer for new LANDIS-II users in Portland, OR. The training will be held on Saturday August 5, and Sunday August 6 and will precede the Ecological Society of America Meeting, also in Portland.The LANDIS-II training is designed for those interested in learning how to use LANDIS-II.  The course will be led by Drs. Melissa Lucash and Robert Scheller, with additional instructors to be determined.  The course will cover parameterizing and analyzing the outputs of multiple LANDIS-II extensions, including forest succession (including NECN/ Century), fire, wind, harvesting, and insects.  The total cost of the 2-day training session is $300 and includes two complementary lunches and ...

  • New version of LANDIS-II succession extension: NECN-Succession v4.1 We renamed the Century Succession extension to the Net Ecosystem Carbon and Nitrogen (NECN) Succession extension.  We made this change because this extension is so substantially different from the original Century model that the name is no longer justified. As in previous versions, NECN simulates monthly growth (including competition among tree species cohorts), mortality and reproduction using species’ life history strategies.  NECN also tracks carbon, nitrogen and water cycling both above- and belowground (roots + soil) and simulates feedbacks between them. In addition, NECN now uses the newly-released Biomass Libraries.  This enables NECN to use the same biomass extensions as Biomass and PnET Succession.  All the Leaf Biomass extensions therefore will be retired.See: ...

  • 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 ...
