The influence of a common parent on sap sweetness among open pollinated sugar maple (Acer saccharum Marsh.) offspring

Wed, 05/08/2019 - 15:08
Abstract: Beginning in the 1950s, the United States Forest Service began to look into the ability to predict and control the heritability of sap sweetness in sugar maples (Acer saccharum Marsh.). A search for genetically superior (sweeter) trees was conducted across 6 states, testing 21,000 trees. Only 53 trees were chosen to be parental stock for the “Super Sweet” sugar maple improvement program. These trees, cloned through rooted cuttings and scion wood grafting, were planted in the Grand Isle, VT clonal bank. One of the five progeny tests of open pollinated offspring from the clonal bank was established in Lake Placid, New York. These trees had their first evaluation at age ten. Each tree had its diameter and height measured, as well as its sap sweetness tested. Now, 35 years after planting, the trees were evaluated again. An inventory was conducted with diameter at breast height, tree height, and live crown ratio measurements. Of the 725 trees planted, only 396 trees remain. Only 258 trees were of size and quality to handle a 5/16” tap. Their sap sweetness was measured at multiple times though out the season. Knowing one of the two parents of each tree allowed for the comparison of the sap sweetness of the different common-parent groups. The data collected did not support that the knowledge of only one parent could be used to predicts a tree’s sweetness relative to any other parent’s offspring. The bigger picture progeny evaluations will continue the “Super Sweet” sugar maple improvement program.

Proposal for Improvements to Alumni Campground Waterfront

Sat, 12/14/2019 - 15:42
Abstract: The Alumni Campground is full of potential. A front country campground in close proximity to many great wilderness experiences. Some of those experiences can be best reached by water and yet the Alumni Campground waterfront is not much more than a single “No Swimming” sign nailed to a tree. This lack of infrastructure has caused degradation of the shoreline as the user base for water craft does use the campground as a starting point for excursions onto the St. Regis waterways but due to a lack of durable launching sites they have created several eroded and denuded spots along the lakes bank. In order to accommodate the amount of use this asset receives and prevent further degradation this proposal is designed to give the Alumni Campground Committee a sensible set of options for structural improvements designed to suit the user bases needs and protect the valuable waterfront resources.
