Long-term calcium addition increases growth release, wound closure, and health of sugar maple (Acer saccharum) trees at the Hubbard Brook Experimental Forest

We surveyed and wounded forest-grown sugar maple (Acer sacchamm Marsh.) trees in a long-term, replicated Ca manipulation study at the Hubbard Brook Experimental Forest in New Hampshire, USA. Plots received applications of Ca (to boost Ca availability above depleted ambient levels) or A1 (to compete with Ca uptake and further reduce Ca availability). We found significantly greater total foliar and membrane-associated Ca in foliage of trees in plots fertilized with Ca when compared with trees from Al-addition and control plots (P = 0.005).

Equating Syrup Price to Sap Price

In fairness to both sap producers and sap purchasers, the price of maple sap should be directly related to the price of maple syrup. This chart helps calcuate that value.

Sugar Maple Tree Improvement Program

Maple producers and rural landowners throughout the maple syrup producing regions of the Northeast have expressed interest in acquiring improved sugar maple seedings for future sap production. A sugar maple tree improvement program for high sap concentration began in the 1960s under the direction of the USDA Forest Service.

Update on the Maple Tubing Sanitation Research in Ontario

In the spring of 1998, a research project was initiated to develop alternative methods for maple produces using plastic tubing systems. Although the results are only preliminary, the development of alternative sanitation methods that may reduce reliance on chlorine is looking very promising.

Impact Of The 1998 Ice Storm On The Eastern Ontario Maple Syrup Industry: A Case Study Of Natural Disaster Policy In Canada

Under Canada’s Disaster Financial Assistance Arrangements (DFAA), the federal government can provide provinces with funds for emergency response and recovery in the event of a natural disaster. This assistance has historically been provided on an ad hoc basis. In recent years, the amount of DFAA assistance has significantly increased without any auditing to determine how effective and efficient these expenditures are in offsetting economic losses due to natural disasters. The goal of this paper is to examine the implications of natural disaster compensation and assistance programs for economic efficiency. A framework is developed to determine if government assistance expenditures have offset economic losses to a specific industry using a case study of the 1998 ice storm and the eastern Ontario maple syrup industry. Projections of damage recovery are used to measure the economic impact of the storm, and a comparison is then drawn between the change in producers’ welfare and government assistance. The implications of the findings for the case study and for future natural disaster assistance programs in Canada are discussed.
