Quarter-Inch Tubing: Is it a Better Option for Gravity Sap Collection?

Ten years ago, 3/16” diameter tubing was introduced to the marketplace as an alternative tubing to 5/16” diameter tubing.  However, recent research shows that sap production in 3/16” tubing drops off as soon as the second year after installation due to microbial growth. A replacement for 3/16” diameter tubing in gravity systems could be 1/4” tubing. With almost twice the aperture of 3/16” tubing (0.049 sq inches compared to 0.0275 sq inches), 1/4″ inch tubing is less likely to plug from microbes yet is still able to create a full column of sap for gravity vacuum. Quarter-inch tubing is currently not available for maple producers but can be procured from other industries and, with modifications, will work for maple production.

Radial growth of hardwoods following the 1998 ice storm in New Hampshire and Maine

Ice storms and resulting injury to tree crowns occur frequently En North America, Reaction of land managers to injury caused by the regional ice storm of January 1998 had the potential to accelerate the harvesting of northern hardwoods due to concern about the future loss of wood production by injured trees. To assess the effect of this storm on radial stem growth, increment cores were collected from northern hardwood trees categorized by crown injury classes. For a total of 347 surviving canopy dominant and subdominant trees, a radial growth index was calculated (mean annual increment for 1999-2000 divided by the mean annual increment for 1995-1997).
