Maple Syrup Season

Americorps • March 11, 2022

March is maple syrup season in Michigan. It may surprise you to know you can make maple syrup from the trees in your backyard. The process may be a little time-consuming, but it is well worth the effort. 

 

Materials Needed:  

  • Drill with a 7/16-inch diameter drill bit
  • Spout 
  • Sap collection container
  • Storage containers, such as plastic or metal trash cans that can hold 1 to 2 gallons for each tap (ex. 25 taps = 25 to 50 gallons storage). 5-gallon pails work well for backyard trees.
  • Pot with high sides and a heat source for boiling sap
  • Candy thermometer 
  • Filter for filtering sap and hot finished syrup
  • Containers for finished syrup (canning jars, syrup jugs, etc.)
  • Optional: Refractometer to measure sugar levels 

 

Trees Used for Maple Syrup: 

Sugar maple is the best tree to use for maple syrup production. The sap contains a high sugar to water ratio and less is needed to produce syrup. However, you can also collect sap from red maple, black maple, silver maple, and box elder. 

Sugar maple has five-lobed leaves and has grey-brown bark.

Red maple has 3-5 lobed leaves and has smooth grey bark. 


Black maple has five-lobed leaves that are dark green and dark grey bark. 

Silver maple has five-lobed leaves that are toothed, the bark is grey-brown.

Boxelder has compound leaves with three leaflets, the bark is grey.  

Remember you cannot collect sap from trees on public land.

Tapping Trees and Collecting the Sap: 

March is the perfect time to collect sap, the nights are freezing and the days are warm. Sap can be collected until the tree starts producing buds, sap collected after this time can be bitter.

Trees have to be at least 10 inches in diameter in order to collect sap. When the diameter is above 18 inches two spouts can be placed. If it is above 25 inches three spouts can be placed. To make measuring simpler below is a table converting circumference into diameter. 

Tapping should be done on a day when the temperature is above freezing. To tap a tree, you first have to drill a hole 1.5 – 3 inches deep at a slight upward angle 4.5 feet above the base. Clear out all the debris and start tapping in the spout gently. Hang the collection bucket, and wait for the sap to pour. 

Sap should be collected every day and stored in a clean, cool, dark place. Otherwise, the sap can spoil or be infested with bugs. 

Making the Syrup: 

The collected sap should be made into maple syrup relatively quickly after collection. Run the sap through a filter to remove any debris. Outside in a large pot boil the sap until the sugar concentration is 66-67%, or until it can coat the back of a spoon. If the concentration is less than 66% then the syrup can spoil later on. If the concentration is more than 67% the syrup can crystalize. When it is done the mixture needs to be 7.25ᵒF above the boiling point of water around 220 degrees Fahrenheit.

It is recommended to boil the sap outside because the amount of moisture boiled off can damage in-home fixtures. On average 40 gallons of sap makes one gallon of syrup. 

After the correct concentration is reached, strain the syrup to remove sugar sand.

Bottle and enjoy! 

Making your own maple syrup is a wonderful hobby. It may help you to appreciate nature and what it provides. If you would like more information on how to properly tap trees and make maple syrup, click Here .  To find out more ways to enjoy the outdoors, click Here .

On the Ground: Volunteers Plant Oak Trees in Port Huron State Game Area

On Saturday, May 10, 2025, MUCC's On the Ground program partnered with the Michigan Department of Natural Resources (DNR), National Wild Turkey Federation (NWTF), and Michigan Forest Association (MFA) for a native tree planting event in Port Huron State Game Area.

On the Ground Junior Hosts its Biggest Project Yet

By Katelyn Helsel • May 14, 2025
On Thursday and Friday, May 8 & 9, 2025, MUCC’s On the Ground Junior (OTG Jr.) program hosted its largest project since the program’s inception in 2016. A total of 160 students and 9 faculty from Norup International Schools participated in a two-day event hosted at Island Lake Recreation Area in partnership with the Michigan Department of Natural Resources (DNR). Between MUCC staff, DNR project partners, and Norup International students & staff, over 175 people volunteered their time to improve wildlife habitat on Michigan’s public lands and recreation areas. This is also the first time that MUCC has partnered with three different divisions within the DNR for one project. Partners from the Wildlife, Parks & Recreation, and Marketing & Outreach Divisions all came together to make this event a huge success.  OTG Jr. is a fully funded field trip program that brings 5th grade – high school students into the outdoors to gain hands-on experience improving wildlife habitat in their local communities. Through activities like native plantings, brush pile building, and invasive species removal, students actively participate in habitat conservation and create a positive impact in the world around them. Educational stations like predator-prey tag and wildlife ID are also available to teach students about population dynamics and other natural resources concepts.

May 2025 NRC Recap

By Justin Tomei • May 8, 2025
The Natural Resources Commission (NRC) met for their May meeting today at Lansing Community College West Campus. The commission voted to return antlered opportunities to the Independence and Liberty hunts at the May Natural Resources Commission meeting. The amendment to restore this opportunity passed after Commissioner Walters withdrew his amendment from April to only partially restore antlered opportunity during these hunts. MUCC testified for the complete restoration of antlered opportunity during these two hunts, per a member passed policy from our 2025 Annual Convention. The commission also voted on, and ultimately accepted, a proposal to allow archery antlerless take in the high snowfall zone in the Upper Peninsula. Additionally, the commission also chose to leave on the table and postpone indefinitely the order to reopen the illegally partially closed coyote season. This prevents the order from dying after today's meeting and makes it eligible for action at a later date. This amendment will remain postponed until the June meeting at the earliest.  MUCC has created the Coyote Coalition to assist in unifying the voice of conservationists in support of Proposal G. To join the Coyote Coalition, visit https://www.mucc.org/coyotecoalition . The commission did adopt proposed fall turkey regulations unanimously. The June commission meeting is Thursday, June 12 in Bay City.
