- Managing Trees and Turfgrasses
-
Trees and turfgrasses commonly share the same landscape. Both require space, light, water, air, essential nutrients, and the appropriate temperature for growth, but there is often a stuggle to maintian quality turf under healthy trees.
- Landscaping to Avoid Wildlife Conflicts
-
Wild animals contribute to our enjoyment of nature, and many species add value to urban and suburban environments. Landscapes are frequently developed to be "environmentally friendly" by providing food and cover for songbirds, waterfowl, squirrels, and other wildlife. Wild animals can, however, damage property or threaten human health and safety. The presence of undesirable species or animal overpopulation often leads to many common wildlife problems associated with urban landscapes.

Watching wildlife is one of the fastest growing outdoor activities in this country. More and more people are buying bird feeders, binoculars, and identification guides than ever before. People's attitudes have been changing. With environmental issues being a major concern these days, people are becoming more aware of nature and natural things.
- Landscape Plants for Georgia
-
Landscape Plants for Georgia is an effort to compile a list of good plants organized into various sizes and groups. It does not list all available plant materials but rather brings together the best possible groupings according to the principles and requirements of good landscape design and plant maintenance. It is not possible to offer pictures of the plants. Many publications, books and web sites, however, have good plant pictures.

- Gypsy Moth Damage
-
The gypsy moth is the most important defoliating insect of hardwood trees in the Eastern United States. Since the turn of the century, millions of dollars have been spent in efforts to control or eliminate gypsy moth populations and to retard natural and artificial spread. In the early decades of this century, outbreaks occurred only in New England; today defoliation by the gypsy moth is far more severe and widespread.

Rating: Votes: 22 Rate ItThere is no doubt that air pollution is one of the most serious problems facing humankind in the 21st century. Air pollution can impact human health, damage the environment, reduce food crops yields, damage property, and reduce visibility. Of the various pollutants, ozone pollution is the one most often linked to emissions from trees. But are trees and forests part of the problem, or are they part of the solution?
- Defining Soil Compaction: Sites & Trees
-
Hits: 1
Added: November 05, 2008
Rating: Votes: 38 Rate ItThe health and structure of trees are reflections of soil health. The ecological processes which govern tree survival and growth are concentrated around the soil/root interface. As soils, and associated resources change, tree systems must change to effectively utilize and tolerate changing resources quantities and qualities, as well as the physical space available. Soil compaction is a major tree-limiting feature of community forest managers and arborists.

- Construction Damage Assessments: Trees and Sites
-
Hits: 1
Added: November 05, 2008
Rating: Votes: 39 Rate ItA key component in assessing development impacts on trees is the systematic evaluation of damage. Many types of damage occur repeatedly over a site, and from site to site. This constant and repetitive damage comes from fundamental anti-tree and tree-illiterate activities. Under scrutiny of a systematic assessment, these patterned damage forms can be prevented or minimized. Some types of damage (one-time, one-spot, chance occurrences) can be assessed but are difficult to prevent. By attempting to categorize damage, patterns can be recognized and steps taken to minimize tree injury and site degradation. Please note that many development activities and the continued presence of good tree quality are mutually exclusive (spacially and temporally). Decisions must be made early in the planning process to maintain tree quality of life and minimize injury.

Hits: 1
Added: November 05, 2008
Rating: Votes: 36 Rate ItSoil compaction is a complex set of physical, chemical, and biological constraints on tree growth. Principle components leading to limited growth are the loss of aeration pore space, poor gas exchange with the atmosphere, lack of tree available water, and mechanical impedance of root growth. There are significant genetic differences between tree species for tolerating various levels of soil compaction.
- Center for Biodiversity and Conservation

Added: November 05, 2008
Rating: Votes: 26 Rate ItWater is essential to tree life. Water is a solvent, transporter, buffer, and reagent for the tree. Water is the most limiting of all essential tree resources. Trees have developed specialized organs, processes, and surfaces to use and conserve water carefully. The value of water lies with its chemical properties, physical reactions, and biological uses. This publication will review what is water, and how it supports life through its properties.
- Assessing Extent and Severity of Mechanical Injuries in Trees

Added: November 05, 2008
Rating: Votes: 34 Rate ItAssessing new mechanical injuries present in a tree using visual, non-invasive observations is difficult and prone to wild variability, inaccuracy, and assessor subjectivity. Assessment of relative damage levels is valuable when precision allows for comparisons across one site and over many sites. Judging recent mechanical injuries from visual criteria, although imperfect, can help gauge the relative amount of damaged tissue visible and estimate the total amount of damaged tissue present.
