Urban forestry

Application of forestry know-how is increasingly sought in the newer, nontraditional industries such as mine-site and rangeland rehabilitation and in urban forestry. Forestry principles are also used in climate change mitigation efforts such as carbon budgeting of practices and calculating emission offsets.

The functional redundancy principle is most appropriate for intensively used environments such as those impacted by urbanization, industrial, agricultural, and forestry activities. When adopting the functional redundancy principle, however, an important... 

Most recent available data show, in 1989, that the combined annual use of maneb and mancozeb in the United States was 8,000-12,000 thousand pounds active ingredient (8-12 million pounds) (Bason and Colburn 1998), making maneb and mancozeb, collectively, the 16th most used pesticides. However, information regarding the quantity of specific pesticides produced or used is difficult to access because it is proprietary (Bason and Colburn 1998), and therefore, this is only an estimate. In 1989, forestry use of maneb and mancozeb, collectively, was less than 1,000 pounds active ingredient, and 1981 urban application was 32,000 pounds active ingredient. 

The relative inputs from these sources are difficult to assess. But generally, water bodies associated with urban regions receive substantial pesticide inputs from industrial and domestic effluents. The major input probably originates from agricultural and forestry practices. 

The contamination of the environment by toxic substances is linked both to industrialization and to intensive agriculture. Xenobiotics reach the aquatic and terrestrial ecosystems from discharges and leaks of industrial products, consumer waste and urban sewage, from farming and forestry runoff, and from accidental spills. 

A number of different types of domestic biomass resources (also referred to as feedstocks) are used to produce bioenergy. These include biomass processing residues such as paper and pulp, agricultural and forestry wastes, urban landfill waste and gas, animal (including human) sewage and manure waste, and land and aquatic crops. There are basically two...
