On March 10 th , 2022 Andrew Bluhm, OSU’s Associate Program Director of the Hardwood
Silviculture Cooperative will provide new insight into a common tree in the Nehalem
Watershed, the Red Alder. This presentation will introduce the characteristics of red alder and
summarize the ecological role that red alder plays in the Oregon Coast Range. We’ll look at how
red alder fits into the big picture of PNW ecosystems then examine the red alder’s effect on
diversity, site productivity, community resiliency, and ecosystem function. Specific emphasis
will be placed on the function red alder has in riparian systems and it’s influence on riparian
communities.
In addition to a B.S. in Forestry from the University of Minnesota and an M.S. in Forest
Ecology/Silviculture from the University of Georgia, Andrew has spent the last 20 years at OSU
as the Associate Program Director of the Hardwood Silviculture Cooperative- focusing on the
biology and management of red alder. Other research projects at OSU have included directing
the red alder management program for the OSU College Forests, managing a long-term study
on alternative silvicultural practices, installing and measuring a Swiss Needle Cast research plot
network, and coordinating the PNW Permanent Sample Plot network. His main duties include
everything from education and outreach, data collection to growth and yield modeling and
everything in between. In his free time, he enjoys exploring PNW old-growth forests in pursuit
of big trees.
Andrew is an expert on this foundational tree in our watershed and will have a wealth of
information to share with us. Hopefully, everyone will walk away from this talk with a new
appreciation for Red Alders and the roles they play in the Nehalem.
The talk will be on March 10th at 7 pm, hosted on Zoom, and is free to the public. The zoom link
