Damaged Maple Sap Tubing Project Protocol

1. Collect your best representative sample of tubing (lateral line with a suggested maximum length of 10 cm/4 inches) that has been damaged by a species of wildlife in your sugar bush. Or if sending a sample of damaged mainline, you should cut in lengthwise like a banana to keep it thin. The clearer the tooth marks the better. If it appears that you have more than one species of wildlife damaging your tubing, please send in a sample of each type of damaged tubing.

2. Give each sample a number to correspond to the accompanying completed Damaged Maple Sap Tubing Data Sheet, and label it with a piece of masking tape.

3. Complete a data sheet for each sample that you think has been damaged by a different species of wildlife.

4. Mail the samples and completed data sheets via Canada Post to:

Bob Gray, 310132 Kemble Rock Road, Kemble, ON N0H 1S0.

NOTE: Canada Post says below 100 gm, the oversized letter rate is $1.94 plus tax equals $2.20. You could use a regular letter-sized #10 envelope or a 9x12” over-sized envelope. The cost for mailing one sample of damaged lateral line tubing including data sheet is the same as mailing six samples with data sheets. Make sure the mailing envelope is not thicker than 2 cm. But if you want to send damaged samples that are thicker than 2 cm, such as spiles or complete mainlines pieces, it will cost you more; almost $15.00.

5. If you have any questions, please contact Bob at or telephone 519-371-9128. Thank you for participating in this project!
