Tools for Forecasting Forest Change: LANDIS-II Development

Title:  Maintaining and Improving the LANDIS-II forest landscape change model.

  We are continually improving our understanding of dynamic ecosystems and landscapes.  We often translate this knowledge into mathematical or logical representations that are folded into the LANDIS-II forest landscape simulation model.  LANDIS-II was derived from the LANDIS family of forest landscape models, developed by Dr. David Mladenoff at the University of Wisconsin-Madison.  LANDIS-II is a state-of-the-art iteration of the LANDIS model and is fully extensible, open-source, and built to rigorous software engineering standards (  LANDIS-II has been used by many groups and throughout the world.  We contribute by prov
iding leadership, training, and development support.   We also develop many new extensions that are shared with scientists world-wide.

Most of the current LANDIS development work at PSU centers around the Century succession extension.  Century v3 was released in May 2013 (Scheller et al. 2012), which added dynamic N feedbacks between vegetation and the soil.   Currently we are working on Century v3.2, which we plan to release in Nov, 2014.  In this version, we will be adding a central, dynamic climate library for LANDIS-Century.  This will require users to provide climate data only once, rather than multiple times for each extension they are running with Century.  We are also incorporating many of the fire weather calculations directly in the Dynamic Fire Extension, to minimize pre-processing time.  This version of Century will also contain the metadata library, which creates xml files so the user can view their LANDIS graphs and maps using the new visualization tool currently under development (details at Current Status)
