As of 2020, New York City Department of Parks and Recreation is the steward of most of the 2.5+ million trees growing within New York City. [18] The New York City Tree Map is an interactive map by the parks department that catalogues more than 850,000 trees in the city. [19] The NYC Department of Parks observes Earth Day and Arbor Day.

Where: Y is the yield (volume, height, DBH, etc.) at times 1 and 2 and T 1 represents the year starting the growth period, and T 2 is the end year. Example: Say that the growth period is from age 5 to age 10, and the yield (height of the tree), is 14 feet at the beginning of the period and 34 feet at the end.
The mean annual increment (MAI) or mean annual growth refers to the average growth per year a tree or stand of trees has exhibited/experienced up to a specified age. For example, a 20-year-old tree that has a stem volume of 0.2 m 3 has an MAI of 0.01 m 3 /year.
Map of wood-filled areas in the United States, circa 2000 [1]. In the United States, the forest cover by state and territory is estimated from tree-attributes using the basic statistics reported by the Forest Inventory and Analysis (FIA) program of the Forest Service. [2]

The “Greatest Trees” list update comes on the heels of a “record” tree-planting year in Fiscal Year 2024, NYC Parks officials said, with over 18,000 trees planted – making the largest ...
The equation for exponential mass growth rate in plant growth analysis is often expressed as: = Where: M(t) is the final mass of the plant at time (t). M 0 is the initial mass of the plant. RGR is the relative growth rate. RGR can then be written as:
Bounded growth, also called asymptotic growth, [1] occurs when the growth rate of a mathematical function is constantly increasing at a decreasing rate. Asymptotically, bounded growth approaches a fixed value. This contrasts with exponential growth, which is constantly increasing at an accelerating rate, and therefore approaches infinity in the ...
