  • 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 ...

  • 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.
