I am working with the biomass production potential of willow birch and alder, so if anybody has these biomass models or yield tables, please kindly let me know.

Data Collection Report for Woody Biomass Products and a Feasibility Research Report for Insuring Fast Growing Trees (such as Poplar & Willow) and other Woody Biomass Products
Deliverable 1: Data Collection Report for Woody Biomass Products
Submitted by: Watts and Associates, Inc.; Nov, 2011.
The aim of this document is to describe our development of parameters for the Greenhouse gases, Regulated Emissions, and Energy use in Transportation (GREET) model for key facets of short-rotation woody crops (SRWC) production, from the field to the conversion facility gate. Two of the most studied SRWC species, willow and poplar, are investigated in this document.

There is a nice and usefull PhD thesis about modelling biomass production, but it is for Poplar, it was done by M.Sc. Wael Ali from TU Dresden-Germany in 2009
