Continuous Forest Inventory (CFI), 1970-2017, Long-term Forest Property Monitoring by State University of New York College of Environmental Science and Forestry, New York, USA

SUNY College of Environmental Science and Forestry (ESF) based in
Syracuse, New York, maintains a series of Continuous Forest Inventory
(CFI) permanent plots on their Forest Properties. ESF has over 700 CFI
plots located on 5 different properties, four properties in the
Adirondack Mountains of northern New York and one property south of
Syracuse. Plots cover northern hardwood species including sugar maple,
red maple, yellow birch, beech, white ash, red oak, white pine,
hemlock, red spruce, and pine/softwood plantations of various species.
Data is collected at ten year intervals on each property starting from
initial plot establishment. Plot information collected includes:
location information, slope, aspect, forest type, cutting history, and
photo of plot. Tree information/measurements include (in general,
trees greater than 3.6 inches diameter at breast height): tree tag
number, species, tree history, diameter at breast height, sawlog
height, bole height, total height, crown vigor, crown class, tree
location, and tree notes. Data is collected/field checked/edited
according to detailed written procedures by ESF professional staff
with assistance of students. Data is collected to monitor general
forest health, growth rates, mortality, and overall forest metrics.
Data is used to calculate standing volumes, stocking of forest trees,
carbon stocking in addition to other information. ESF Forest Properties with CFI plots:
