At SilvaBio, we create superior seedlings.
SilvaBio’s Story: Better Trees, Faster
For the first time, an iconic tree species—the American chestnut—is being brought back from functional extinction. SilvaBio is using a powerful science platform not only to restore the American chestnut, but also to protect and restore other valuable, at-risk hardwood species.
America’s hardwood forests contribute more than $350 billion to the economy, support biodiversity, and offset nearly 15% of U.S. carbon emissions. Yet they face immediate and growing threats. Invasive pathogens eliminated the American chestnut, erased three-quarters of our elm trees, and are now devastating ash while threatening oak, walnut, and beech. Traditional solutions have fallen short. SilvaBio is different.
Our research collaborators at SUNY ESF developed the first blight-tolerant American chestnut, Darling 54. Building on this breakthrough, SilvaBio is developing American chestnut seedling varieties suited to diverse regional conditions and scaling production for distribution from Mississippi to Maine. We are also applying our biotechnology platform to accelerate disease-resistance solutions for additional at-risk hardwood species.
SilvaBio is a Public Benefit Company committed to developing and supplying superior seedlings to restore America’s forests and strengthen the ecosystems and economies they support.

We have become great because of the lavish use of our resources. But the time has come to inquire seriously what will happen when our forests are gone”.
Theodore Roosevelt
Our Approach
Traditional approaches to tree disease often take decades to achieve modest gains. SilvaBio accelerates this process by using advanced genomics and machine learning to identify genes associated with disease tolerance and other desirable traits, enabling us to select for, or engineer, improved varieties. We pair these tools with speed breeding to rapidly advance new lines, proprietary micropropagation to scale production, and partnerships that bring reforestation efforts to forest scale.
By supplying superior American chestnut seedlings to landowners and conservation organizations, we make true, forest-scale restoration possible—better trees, faster.
Our integrated platform combines genomic, phenotypic, and environmental data to drive rapid cultivar development and deliver high-quality seedlings that meet demand across timber, conservation, and climate markets.
We have developed distinctive lines of Darling and DarWin blight-tolerant chestnut seedlings, accelerated production, and look forward to distributing these trees to select customers. We will soon make disease-resistant ash and elm seedlings available.
Our mission is to restore the health and resilience of North America’s forests through science-driven solutions to tree disease.
