Assessing Damage to Maple Sapwood Caused by Tapping

The area of stained sapwood associated with tapping or other wounds in maple trunks has long been interpreted to represent the area of wood that is compartmentalized, and thus unavailable for sap flow. We tested this interpretation by passing dye through maple stems that had been tapped and observing the area that was blocked. Our results indicate that the blocked portion of the trunk associated with a wound taphole is somewhat larger than the area which is visually compartmentalized (stained).

Making Maple Syrup in a Land of Funnel Cakes and Pulled Pork

Making maple syrup in the mild climate of southern Illinois is lesspredictable and more work. The sap seasons are longer, there is an almost certain need to freshen the tap holes, and the freeze-thaw cycles are less predictable.

Response of Sugar Maple to Calcium Addition to Northern Hardwood Forest

Watershed budget studies at the Hubbard Brook Experimental Forest (HBEF), New Hampshire, USA, have demonstrated high calcium depletion of soil during the 20th century due, in part, to acid deposition. Over the past 25 years, tree growth (especially for sugar maple) has declined on the experimental watersheds at the HBEF. In October 1999, 0.85 Mg Ca/ha was added to Watershed 1 (W1) at the HBEF in the form of wollastonite (CaSiO3), a treatment that, by summer 2002, had raised the pH in the Oie horizon from 3.8 to 5.0 and, in the Oa horizon, from 3.9 to 4.2. We measured the response of sugar maple to the calcium fertilization treatment on W1.

Associations of calcium and aluminum with the growth and health of sugar maple trees in Vermont

We compared tree growth and crown condition with soil and foliar elemental composition in 14 sugar maple (Acer saccharum Marsh.) stands in VT, USA, to evaluate if deficiencies or imbalances in cation nutrition were associated with growth and health reductions in native stands. The Till Source Model (TSM) was used to select study sites potentially high or low in calcium (Ca) by predicting the relative Ca concentration of soil parent material derived from glacial till. The TSM successfully identified high or low levels of soil Ca (P = 0.031) and foliar Ca (P = 0.011) among stands.

A History of the Gooseneck: The Brower Sap Piping System and the Cary Maple Sugar Company

The initial application of plastic tubing for gathering maple sap in the 1950s was indisputably one of the most significant technological developments of the maple industry in the twentieth century. However, the first viable tubing system was introduced over forty years earlier as a gravity drawn system made completely of metal.

New Tapping Guidelines

Here I explain why maple producers should know the growth rate of trees in addition to diameter to determine the number of tapholes per tree.

Carbohydrate reserves in Acer saccharum trees damaged during the January 1998 ice storm in northern New York

To assess the effect of the ice storm of January 1998 on sugar maple (Acer sacchan~m Marsh.) tree health, starch, and soluble sugars in twigs from two damaged sugarbushes (younger: trees 50-100 years old, and older: trees approximately 200 years old) in northern New York were measured throughout the leafless phase (September 1998 – May 1999). Trees severely damaged by the ice storm exhibited signs of recovery during the first growth season (1998), that is, greater numbers of lateral (epicormic) shoots and increased wood production in the current year growth ring of branches at mid-crown, and high concentrations of starch in the twigs at the time of leaf drop.

Evaluation of Alternative Sap Ladders: Summary of 2002-2003 Research Project

This research project was established in the spring of 2002 to study the technique of lifting sap with simple “sap ladder” tubing structures. It was conducted during the production seasons of 2002 and 2003 in an operational setting at Wheelers Maple Products in Lanark County, Ontario.

Some Background on the Asian Longhorned Beetle

The beetles were first discovered in Brooklyn, New York in 1996 and spread to neighboring Queens, infesting areas in Sunnyside, Woodside, Astoria, Long Island City, Maspeth, Ridgewood and later in Bayside and Flushing. Small infestations were also found in Flushing Meadows Park, Forest Park in Woodhaven and Kew Gardens Hills. New York city has lost over 4,000 trees because infested ones have to be cut down, chipped and burned.

1998 Ice Storm Effects on the Health and Productivity of Sugar Bushes of Eastern Ontario: Part 2

In 1998, fifteen managed sugar bush blocks with 7% to 72% ice-induced crown damage were established in eastern Ontario. All blocks received dolomitic lime (calcium and magnesium) and phosphorous (P) and potassium (K) treatments in June 1999. Initial crown damage, fall root starch, sap production and sweetness were all measured. Syrup production was calculated.
