Structure Condition Services Stressors
Vermont's maple industry contributes over $300 million in total sales to the state's economy each year1, yet it is heavily dependent on favorable climate conditions and the health of sugar maple trees. Here, we assessed the condition of the maple syrup industry as the yearly value of the total maple syrup production in Vermont. The current year is scored as the distance between zero and the maximum value + 10% of the range.
Maple syrup production not only benefits the state's economy but also the state's forest as a whole, especially when it comes to private forest lands. With the majority of private landowners tapping into this resource, they are not only giving value to the state’s most predominant tree2 but through the active harvest of this resource, private forests are managed and maintained as an active forest with many maple syrup producers participating in the state's current use3 program. It should be noted that these estimates come from surveys sent to maple syrup producers by the USDA. These results represent the portion of the producers that respond to the surveys and are a representation of the numbers that they report back.

The score is calculated using a target value and the historical range of the the entire long-term dataset. The higher the score, the closer this year's value is to the target.
Once the score is computed for each year, the trend in scores over time is calculated. If the trend is significantly positive or negative, the long-term trend is marked as increasing or decreasing respectively.
Distance between 0 and target (scaled 1-5)
Data maximum + 10% of range
|Directionality of scores||
Higher values in the data are better.
|Minimum value used in scoring||
Data minimum - 10% of range or 0, whichever is greater
|Maximum value used in scoring||
Data maximum + 10% of range
We used the total annual maple syrup revenue (in dollars) reported by the USDA National Agriculture Statistics Service1. We set the dataset target as the maximum value in the dataset plus 10% of range. The annual score was then computed as the distance between the the lower scoring bounds (either the minimum value in the data minus 10% of range or 0, whichever was greater) and the target. This difference was then scaled 1-5.
Timber harvested from Vermont's forests provide jobs and income to the state, and support the maintenance of forest land.
Aquatic species that live in forested streams provide an assessment of the health of the surrounding forest.
The ability of forests to support big game species for hunting is an important service on which many Vermonters rely.
The amount of carbon stored by forests helps offset rising atmospheric carbon dioxide concentrations.
Maple syrup production is an iconic staple of Vermont's landscape and is reliant on the continued health of maple trees.
The number of people using Vermont's forests for camping and hiking provides a measure of the value of our forests for recreational uses.
The number and diversity of bird species that live and use forested habitats provides a sense of the quality of Vermont's forestlands for a variety of species.
