Can You Tell History from Syrup Tap Scars?
Scars in a tree at the Indian Creek Nature Center reveal maple syruping history.
Back in 1979 Rich Patterson and volunteers approached a husky Box Elder tree, armed with a drill, spile, and buckets. It was early March. Nights were cold and frosty, followed by warm sunny days. Syrupin’ weather.
Oozing Out the Sap
As soon as the drill’s bit cut through the tree’s bark, clear watery sap oozed out.
Rich gently tapped in a metal spile and hung a bucket under it. By day’s end, two gallons of clear sap nearly filled the pail ready to be boiled into syrup.
If not overdone tapping just harvests a small percentage of a tree’s sap. It’s sort of like a person giving blood. Taking a little does no harm. Healthy trees quickly create a scab over the tap hole, somewhat like a human body heals a scratch. As the tree grows and its trunk diameter swells, wood forms over the old tap hole. It’s fine to tap that tree again next year, the year after, and every following year.
Syruping season ends when night temperatures don’t drop below freezing. That’s when spiles are pulled, leaving the hole for the tree to heal.
Aging Out of Production
That’s what happened to the Nature Center’s tree. Box Elders are true maples capable of producing sap for quality syrup, but they are short-lived. An 80-year-old Box Elder is, well, elder and near life’s end. After being tapped for 40 years in a row the Nature Center’s box elder reached the end of its days converting solar energy into sugar. After its death staff felled it, revealing at least 30 tap scars. The oldest ones are closest to the center of the tree’s trunk.
Syruping is a fun late winter activity. To learn more visit the Indian Creek Nature Center during syruping season. It holds a fun Maple Syrup Festival in late March each year. For details check out Indian Creek Nature Center’s website.
Thanks, box elder for sharing some of your sap all these years.
