- Biology and host associations of redbay ambrosia beetle (Coleoptera: Curculionidae: Scolytinae), exotic vector of laurel wilt killing redbay trees
-
The redbay ambrosia beetle and its fungal symbiont, Rafaelea sp., are new introductions to the southeastern United States responsible for the wilt of mature redbay, Persea borbonia (L) Spreng., trees. In 2006 and 2007, we investigated the seasonal flight activity of X. glubratus, its host associations, and population levels at eight locations in South Carolina and Georgia where infestations ranged from very recent to at least several years old.
- Comparing Moisture-meter Readings to Standard Oven-dry Moisture Content
-
Southern pine dimension lumber is produced by a large number of mills in Georgia, in great quantities. All lumber used where it must meet building codes has to be grademarked. For grademarking, moisture-content limits for the specified grade must be met.
- Alaska Community Forestry Program
-
A community or urban forest is all the trees growing in and around a city, town, or village. It includes trees in parks, school yards, home landscapes, utility rights-of-way, vacant lots, greenbelts and along stream banks. Shrubs, ground covers, soil, wildlife, and water bodies are also part of the urban forest. Streets, buildings, utilities, parking lots, and, most importantly, people, are an integral part of the urban ecosystem.
- Understanding the Pesticide Label for Citrus Grove Workers
-
When used properly and according to their labels, pesticides can control, destroy, or repel pests such as weeds, insects, rodents, birds, fungi, bacteria or other organisms that cause loss or damage, or may be harmful to people's health. Pesticides handled in a careless manner can endanger the health of the applicator, other people, animals, plants, or the environment.

Added: October 31, 2008Assessing tree strength is a complex process. The dynamic nature of how trees resist forces include soil, tree, and environmental components. Cavities signify a common loss of cross-sectional area and associated strength in stems. Small cavities centered in the middle of stems (only wall four sustains the compartment), have small impacts on relative stem strength. Relatively large diameter cavities (more than 60-70% of diameter loss) represent major impacts to the structural integrity of stems.

Added: November 05, 2008The scientific community now embraces the emerging field of urban ecology as both valid and central to understanding the global environment. Given the concentration of human activity in urban centers, that humans are the dominant species in all ecosystems, and the pace of environmental change, urban ecology is a critical area for environmental research. Understanding urban natural resources and urban natural systems also has important implications for public health, economic development, education and community development in urban areas.
- Large Trees For North Carolina
-
Large trees are dominant features in the landscape. Many plans rely on trees for several design functions: to provide background, enclosure, define spaces, help reduce noise and unsightly views. Trees also provide needed shade, channel breezes, and break forceful winds. They also help the environment by filtering pollutants and exchanging oxygen for carbon dioxide.
