IMPORTANT NOTE:  NECN is incompatible with earlier versions of various Biomass extensions. Please do the following to ensure successful installation:
  1. Use the Windows control panel to uninstall earlier versions of LANDIS-II and all extensions. 
  2. Use the Windows File Explorer to navigate to C:\Program Files\LANDIS-II\ and delete all .dll files. 
  3. Install the Biomass extensions (e.g., Biomass Harvest v3.0). 
  4. Install NECN last. Brief Description:Aboveground biomass generally follows the behavior of previous Biomass Succession extensions with cohorts that have biomass (g m-2). In addition, below ground processing of Carbon and Nitrogen is simulated following the logic of the Century nutrient cycling model (v4.0).
