Sp628 Choosing 'Sewer Safer' Trees, The University Of Tennessee Agricultural Extension Service

Forestry, Trees, and Timber

Municipal sanitary sewer systems are, second to the drinking water system, the most important public health asset of a city. When they are properly operating, that is, carrying the wastewater and sewage away from homes and businesses and to the treatment plant, they protect the public from the potential health hazards associated with human waste.

Sp656 Shade And Flood Tolerance Of Trees, The University Of Tennessee Agricultural Extension Service

Forestry, Trees, and Timber

Most trees have very specific requirements for how much sunlight or shade that they are able to endure. Some trees do well in full sunlight, while other trees do not perform as well. Some trees are more adaptable than others to varying amounts of sunlight. Recognizing the light requirements of different species of trees will assist in proper tree selection in the landscape and will promote healthy trees.

As with light requirements, different trees have different tolerances to flooding. This factsheet discusses and lists the comparative tolerance of trees to shade or sunlight and to flooding.

At any given moment, there are 1,800 thunderstorms in progress somewhere across the earth. Lightning detection systems in the United States sense an average of 25 million lightning strikes per year.

Sp659 Cabling, Bracing And Other Support Systems For Trees, The University Of Tennessee Agricultural Extension Service

Forestry, Trees, and Timber

Urban trees often need some degree of supplemental, physical support to reduce the risk of structural failure of the crown or root system. Cabling, bracing, guying and staking can provide a solution for these tree failures. Tree-support systems help support the tree by limiting the movement of branches, leaders or the entire tree. They can reduce the risk of injury to humans and damage to property by providing supplemental support for structurally weak areas of the tree.
