Recent mast seeding events occurred in Vermont in 2000, 2006 and 2011. The area was logged in the last century, but the study site has since Quebec sugarmakers averaged 3.43 pounds per tap, according to the Quebec Maple Syrup Producers, the industry trade association. The same population was used in an earlier study of a 1984 mast year cohort of sugar maple seedlings (Taylor and Aarssen, 1989). A mast year for sugar maple occurred at the study site in 1984. This is a mast year for sugar maples, when they produce an overabundance of seeds. The frequency of these mast years varies, sometimes every seven to 10 years, and then quickening like a heartbeat to every two or three years; consecutive mast years … This year was expected to be a mast year. Because most sugar maple seedlings become established beneath or near parent trees, 25 of the largest canopy ('target') trees within the population were selected for sampling. Quebec’s 11,300 sugarmakers made more than 159 million pounds of maple syrup this season, a dramatic increase of 41 million pounds over last year. Both types are important year-round food sources for wildlife, but hard mast is often considered more important, especially as a winter food source, due to its higher energy content. In sugar maples, mast seeding tends to occur every two to five years. Study site-The study site was a 1 0-hectare woodland located on the property of the Queen's University Biology Station at Lake Opinicon in southeastern Ontario, Canada (44034'02"N, 76021'52"W). Field Sampling. Overstory composition in both soil types was dominated by red oak (Quercus rubra) and chestnut oak (Quercus montana), but the overstory on shale sites was more diverse (14 tree • The New York Times featured an article in January 2015 about Maple syrup season. This has prompted naturalists to conclude that 2020 is likely a mast year for British woodland species, a year in which trees such as oak, beech and maple produce bumper crops of fruit. For example, the optimum age for beech trees is >60 years with 14” dbh (diameter breast height), >50 years with 14” dbh for ash and maples, and 30-100 years with 10” dbh for cherry trees. In a mast year the trees synchronize with one another and flower at once, leading to more free flowing sap. Here on campus, we've had our own banner spring, with a crop of inspiring speakers reminding this Dean of what being part of a university is all about—a community of learners where students and faculty gather together for stimulating exploration of ideas and attempt to … This research investigated overstory and understory forest composition for 10 sites derived from either shale or sandstone conglomerate parent material on the Shawangunk Ridge in eastern New York. Rapp and Crone’s research shows that in Vermont, syrup production declined following every mast seed year. “Both seeds and sugar are made from carbohydrates stored in trees,” Crone says. Farmers in the “maple belt” and maple syrup producers would need to be prepared for this surplus. We examined whether particular years of mast seed production in sugar maple (Acer saccharum) are associated with increased likelihood of cohort recruitment success into the sapling stage over three decades of heavy browsing pressure from white-tailed deer in a mature woodland population in southeastern Ontario, Canada.The population was sampled in 2014 for seedling …
