Sept 7: Maple Workshop Includes NNYADP Research Update, Cornell Specialists

NNY Maple Specialist Adam Wild

Croghan, NY. The September 7 Maple Tubing Workshop from 9:00 am to 11:00 am at Pierce’s Sugar Spigot, 11601 State Route 812, Croghan, NY, will include an update on maple industry research funded by the farmer-driven Northern New York Agricultural Development Program (NNYADP). Cost is $5 per farm; register by Spetember 4 with CCE Lewis County, 3115-376-5270, lewis@cornell.edu.

Northern New York Maple Specialist Adam Wild, director of the Uihlein Sugar Maple Research Forest in Lake Placid, NY, will present information on the 2019-20 NNYADP-funded project that is evaluating the timing of tapping to determine if syrup production and profitability can be enhanced by capturing early sap runs and then retapping before the holes dry shut in a single season to capture later sap flow. New York State Maple Specialist Stephen Childs of Cornell University will take workshop participants through the latest information, technology and research on maple tubing systems and the best way to install them.

NNYADP-funded research has contributed to the growth of the regional maple industry from $5 million per year to a more than $12 million annual impact across the northern part of New York State. The results of recent NNYADP maple research projects are posted at https://nnyagdev.org/index.php/mapleforest/maple/.

NNYADP Maple & Birch Tapping Research Results: Responding to Climate

Lake Placid, N.Y.: December 10, 2018  The Northern New York Agricultural Development Program has posted a research update with data to help maple and birch syrup producers respond to variable climate conditions.

“Maple, and now birch, syrup producers are on the front lines of dealing with the effects of climate change and the variations that have increased the unpredictability of when sap will flow,” says Dr. Joseph Orefice, director of the Natural Resources and Forest Program at Yale University. Orefice managed the tapping trials in Northern New York while director of the Uihlein Maple Research Forest in Lake Placid, N.Y.

The project has established baseline data for continuing efforts to determine the optimal time to begin tapping birch trees in conjunction with maple production.

“Birch syrup is a relatively new agricultural product being produced in Northern New York as a way for maple producers to diversify their revenue streams and optimize capital investments in forestland and syrup-producing equipment,” says Orefice.

The report posted under the Maple tab at www.nnyagdev.org compares sap and syrup yields based on various tapping times of maple and birch trees at the Uilhein Maple Research Forest in Lake Placid, N.Y., and at the Paul’s Smith College Forest in Paul Smiths, N.Y.

The trials conducted in January through May of 2018 including the tapping of paper and yellow birch trees immediately after finishing the tapping of maple trees, during mid-maple season, and post-maple production season.

Sap collection was impacted by taphole closure, particularly with the maple trees that were tapped early in January, and with birch trees likely due to bacterial buildup in the taphole before birch sap begins to flow.

Orefice allows that using new spouts might mitigate taphole closure in birches, as they do in maple sap production, however, temperatures are higher during March than January and bacterial buildup in birch tapholes during March will occur faster than in maple tapholes during January.

“While much more research is needed to determine ideal weather conditions to predict the start of birch sap flow, we suggest that birch syrup producers wait until around the end of maple season to tap their birch trees. This will assure that they do not have early taphole closure of birch and will also reduce complications in the saphouse related to collecting the two different types of sap,” Orefice concludes.

For maple producers, the report notes that early pre-season tapping of maple trees is competitive with tapping in mid-February.

“Waiting to tap until late February and early March risks missing early-season sap flow events and having less total season production,” Orefice summarizes. “Low sugar contents during January sap flow events were likely a result of sugar not yet being converted from starches within the tree and also not being released into the maple sap.”
