The methods followed in the creation of the dataset, including description of field, laboratory and processing steps, and quality control procedures
Random plot location
60 randomly-located 1/20th hectare plots were established within Winooski
Setting reference objects
The plot center is rigorously identified using physical reference objects to allow surveyors to revisit these plots in the future and track changes over time.
Identify and measure trees
Each tree in the plot is identified at least to genus and measured for height, diameter, crown height and width, percents dieback and missing, crown light exposure, and spatial relationship to nearby buildings.
Assess land use and ground cover
Land use proportions and ground cover proportions on the plot are recorded.
Data are submitted to the US Forest Service i-Tree Eco analysis service to generate city-wide estimates of the composition, condition and ecosystem services of the urban canopy in the city.
