Information about growth of trees and forests

LIGNUM group

 

Short history. Originally LIGNUM was devised in an attempt, using object oriented approach, to define data structures in a single tree in a way that enables linking of metabolic activities and structural description in an consistent way. The idea was that this kind of a model could be used for various puposes without the need of major changes for each use. The original team working with this contained members from different disciplines: forest ecology, forest growth and yield research, process-based modelling, forest entomology, computer science and methods of artificial intelligence, and they are : E. Nikinmaa, J. Perttunen, H. Saarenmaa, H. Salminen, R. Sievänen, and J. Väkevä. The reports Salminen et al. 1994 and Perttunen et al. 1996 cover this work.

 

Currently Risto Sievänen, Eero Nikinmaa and Jari Perttunen form kind of a "core group" of LIGNUM.
