MA Ch.1 Municipal Arboriculture & Urban Forestry Flashcards
Presence and concentration of pollutants
Air Quality
Pollutants, produced by trees, that can contribute to the formation of ozone and Carbon monoxide
Biogenic volatile organic compounds
Atmospheric gas produced by animals during respiration and used by plants during photosynthesis to produce sugars; an important greenhouse gas
Carbon dioxide
Storage of carbon in plant tissues
Carbon sequestering
Improvements to the natural world provided by the urban forest
Environmental benefits
Rise in temperature that the earth experiences because certain gases in the atmosphere trap energy from the sun
Greenhouse effect
Gases in the atmosphere including water vapor CO2 nitrous oxide and methane that trap the energy from the sun increasing the earth’s temperature
Greenhouse gases
Organic chemical compound containing hydrogen and carbon atoms. The one that come from fossil fuels are linked to pollution and global warming
Hydrocarbon
A specialized field of Arboriculture and urban forestry that deals with management of planted and naturally occurring greenspaces on public land in communities
Municipal Arboriculture
Gaseous compound that results from the high temperatures are in internal combustion engines. A major component of acid rain
Nitrogen oxide
Reduction of sound levels
Noise attenuation
Gas formed by photochemical reaction of nitrogen oxides and volatile organic compounds in ultraviolet sun light and moisture
Ozone
Small solids suspended in air that are generated by combustion of fossil fuels, construction and demolition, industrial processes, soil tillage and erosion, and complex reactions between sunlight and gaseous pollutants. Associated with respiratory and cardiopulmonary diseases and cancer
Particulates
Component of smog causes respiratory problems and eye irritation toxic to plants in high concentrations
Peroxyacetyl nitrate
Method to appraise the monetary value of trees considered replaceable with nursery or field grown stock. Based on the cost of replacement with the same or a comparable species of the same size and in the same as lace, subject to depreciation for various factors
Replacement cost method
Mix of atmospheric chemical compounds including ozone, peroxyacetyl nitrate, nitrogen oxide, and hydrocarbons that react chemically when exposed to ultraviolet light
Smog
Rain or snow melt that flows over the ground
Stormwater runoff
The most abundant gaseous pollutant results from burning coal and oil. Can be a respiratory irritant. It is one of the major components of acid rain.
Sulfur dioxide
Method to appraise the monetary value of trees considered too large to be replaced with nursery or field grown stock. Based on developing a representative unit cost for replacement with the same or a comparable species of the same size and in the same place subject to depreciation for various factors.
Trunk formula method
Management of naturally occurring and planted trees and associated plants in urban areas.
Urban forestry
Phenomenon of cities having air temperatures warmer than adjacent rural areas and producing more smog
Urban heat island
