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 New York State Department of Environmental Conservation (informally referred to as NYSDEC, DEC, EnCon or NYSENCON) is a department of New York state government. [4] The department guides and regulates the conservation, improvement, and protection of New York's natural resources; manages Forest Preserve lands in the Adirondack and Catskill parks, state forest lands, and wildlife management ...
Permissible activities on New York state forest lands include hunting, trapping, fishing, hiking, snowshoeing, cross-county skiing, horseback riding, snowmobiling, and camping, although some properties prohibit some of these activities. [2] Motorized vehicle use is prohibited except for on specified roads and trails.
By contrast, the (roughly) 300-year-old Ice Glen pine in Stockbridge, Massachusetts shows approximately half the annual growth rate of trees in the 90- to 180-year age range, averaging just 5.8 cubic feet (0.16 m 3) per year over a five-year monitoring period. Volume increased as a result of increases in both height and girth.
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 ...
According to a 2005 report conducted by the FAO, Vietnam has the second highest rate of deforestation of primary forests in the world, second to only Nigeria. [44] More than 90% of the old-growth rainforests of the Philippine Archipelago have been cut. [45] Other Southeast Asian countries where major deforestation is ongoing are Cambodia and Laos.
A grove of 12 old-growth beech trees estimated to be over 200 years old in 1912. When 75th street was expanded to the shore, the new road ran through the grove. [62] The grove stood until the Jacobus family sold the land. In the early 20th century, an apartment building was built on the site and the trees were destroyed. [63]
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:
