Willow Woody Biomass
EcoWillow 2.0

Economic Analysis of Shrub Willow Biomass Crops


EcoWillow 2.0 is the most comprehensive and up-to-date financial analysis tool for shrub willow biomass crops. Originally released in 2008 after 20 years of research on shrub willow crops at SUNY ESF, EcoWillow 2.0 was released in 2014 and incorporates the latest data from research trials across North America and commercial willow production in New York State. A new series of fact sheets is also available below to support your use of the model. EcoWillow has been downloaded by over 1000 users in 70 countries and will continue to updated and improved by staff at SUNY ESF as new information becomes available and best practices for shrub willow crops continue to be developed.

Instructional Video

The video on the right side of this page and linked here is a pre-recorded webinar on EcoWillow 2.0 that was hosted by the NEWBio project in February 2015. This webinar is presented by Justin Heavey and Dr. Timothy Volk, willow researchers at SUNY ESF. This webinar explains and demonstrates some of the new features of EcoWillow 2.0 in more detail, provides a brief tutorial, models several example crop production scenarios showing the impact of key variables on production costs and profitability, and answers questions about the model and its use. Key updates to the model covered in this video include a new “fields” module for the inclusion of multiple field locations, transport distances, and headland areas in one project analysis; updates to the harvest module based on time-motion studies of the latest harvesting technology developed in partnership with Case New Holland; and the outputs of example crop production scenarios.


Thank you for your continued interest in the EcoWillow model and willow biomass crops!
