It’s true, not all tree shade is created equal. Broad-leaved, deciduous trees, in general, cast a broader shadow than many evergreens, such as pine species. This is due, in part, to the shape of the mature tree canopy. When grown …
Who is responsible for taking care of the tree in front of my house?
Rights and responsibilities for trees in front of houses vary across states and municipalities. Residential yards abutting public roadways are often overlain by a right-of-way adjacent to the pavement that permits the municipality or state to maintain the road and …
Are pine trees a good option for planting around my home for energy conservation?
All pine species have evergreen needles and grow seed cones; however, pine species vary considerably in where they are found, how big they get, and how fast they grow. Therefore, pine species also vary in their potential for energy conservation …
What should I do after a storm has damaged my tree(s)?
Storm-damaged trees should be evaluated by a professional arborist. A Certified or Consulting Arborist may recommend removal or various improvement measures such as pruning, cabling, lightning protection, root invigoration, fertilization, etc.
The Arbor Day Foundation has a nice page …
Is soil erosion a serious problem in urban areas?
Plants such as trees and grasses help hold the soil in place. Soil erosion is a serious problem in urban areas due to the loss of vegetation from construction, neglect, and/or overuse of surfaces in public recreation and gathering places. …
Do urban forests play a role in mitigating global climate change?
Urban trees play a role in reducing atmospheric carbon dioxide directly by storing carbon in the trunk, branches, roots, and leaves until these tree parts die and decay. Trees also reduce energy consumption by shading the sun, cooling the air, …
What is evapotranspiration?
Evapotranspiration is a combination of evaporation and transpiration. Evaporation is a physical process that transforms liquid water into vapor by absorbing heat. Transpiration is the biological process of plants releasing water vapor through leaves. This water was previously pulled up …
Do trees and other vegetation help reduce urban-water runoff?
Trees and other vegetation in urban areas considerably reduce urban-water runoff. As rain falls upon vegetation, it clings to the rough surfaces of leaves, branches, and trunks. This is called interception. Some of the water evaporates back to the atmosphere. …
How does vegetation help reduce noise pollution in urban ecosystems?
Vegetation reduces noise pollution through a phenomenon called sound attenuation, which is the reduction of sound intensity. Normal attenuation of sound occurs as the energy of sound dissipates over long distances until not enough energy is left to vibrate …
I want to select the best spot for my tree. How can I find out where the sun will be in the summer and winter?
The position of the sun is expressed in altitude (or elevation) and azimuth, both of which will vary by location, time of day, and time of year. Altitude refers to the height of the sun over the horizon (higher in …
