Maple Events on the Horizon

Join Associate Professor, Dr. Stephen Matthews to learn about USDA Forest Service’s Climate Change Atlas.  He will introduce this tool that is based on over 2 decades of research with a goal to help us understand the impact of climate change on our trees. When you have heard us talk about red maple’s favorable position in the face of an uncertain future, the work of the Climate Change Atlas is what we are drawing from.  Register for the April 12th webinar HERE.

Future Generations University is offering a webinar this Thursday evening, March 21st at 7 PM.  The Appalachian-based program Out of the Woods hosts guest speaker Dr. Catherine Belisle (Cornell University) and Lindsay Kazarick (Future Generations University) to discuss maple confections and event-based marketing. REGISTER here.

Here’s a little bonus video to enjoy featuring Cornell University’s Arnot Teaching and Research Forest in New York.

SAVE THE DATE for 2024’s Ohio Maple Days – December 7.  We will be shifting locations this year due to a scheduling conflict at our normal venue at Ashland University.  You can look forward to this year’s Ohio Maple Days landing at Wooster’s Secrest Arboretum.

And speaking of events, we hope everyone got to participate in Ohio’s Maple Madness Tour.  Whether by opening up your own operation to visitors or by venturing out on the tour yourself, Maple Madness is a signature springtime event that should not be missed.  We hosted somewhere just shy of 100 folks throughout Saturday, March 2nd at the Ohio State Mansfield campus.  Thanks to all who came, and a BIG THANKS to everyone who led tours of the wetlands, sugarbush, and kept the evaporator steaming all day long.

 

Mid Season Update & Cornell’s Maple Climate Network

by at

Our sap season at the OSU-Mansfield sugarbush is well underway after tapping trees beginning January 29 and officially collecting sap by February 1.  While I still have time to change my mind, my current belief is that we nailed the “When should we tap” question with the right answer this year.  Our first run was a solid week long with solid nightly resets below freezing as this forecast basically fulfilled itself just like the weather prognosticators predicted.  Though overall sap volume was not as productive as it could have been, sap Brix started off at 2.1 and stayed ready right around 2.0.  By the end of the first run and through roughly Valentine’s Day, the woods got downright crunchy and dry highlighted by a few days that pushed temperatures almost up to 60 F.  During a second run of several days, flows remained average at best but Brix still hovered at a good sap: syrup making ratio.

As far as growing degree days go, we are almost exactly halfway to seeing silver maples break bud, and the rest of February and first couple days of March as currently forecast will likely push us right up to that threshold.  If I had to guess, we will be shutting off a couple main lines that are heavy “Rilver” (red x silver hybrids) in the March 1-5th range and hoping for another week or two production out of our sugar maples.

While there are a few nights with temperatures forecast for the low-mid 20s, it appears the OSU-Mansfield sugarbush will spend more nights above freezing as February drags into March.

Checking forecasts further north in towns like Chardon, Middlefield, and Geneva, all the way north to Ashtabula on the lakeshore, most nighttime temps are currently sitting on the wrong side of 32 Fahrenheit and the next 2 weeks offer only a few opportunities at hard overnight resets to stimulate good sap flows.  What March holds in store, I certainly don’t know.  And if another great sugaring weather pattern emerges, will our taps still be putting out lots of high quality sap if and when that occurs?  What I do know is this – Mother Nature has always and will continue to be the one holding the cards.  Even if my hindsight is happy with our initial tapping dates and I don’t eventually wish for a do-over, that is still no guarantee of a banner season.

As this year’s season ticks along, we’re excited to have an Ohio maple producer in Geauga County hosting a tree monitoring system for Cornell’s Maple Climate Network database.  You can track various metrics, such as Total Sap Production, Atmospheric Pressure, Tree Pressure, Rainfall, and Soil Moisture on this Dashboard.  Just look for the legend indicator so you can focus on some Ohio data and watch the season unfold from a single sugar maple tree’s perspective.  A great project with lots of potential, we’re glad Ohio can be a small part of the effort.
