Tree care, from diseases to selection, will be the focus of an upcoming University of Georgia symposium set for Aug. 21 at the DeKalb County Extension office in Decatur.

Some landscapes — like forests — are known for keeping carbon dioxide out of the atmosphere. Others shed carbon dioxide or other gasses that can affect the environment. Calculating just how much of each gas is held or released can be difficult but University of Georgia scientist Monique Leclerc has literally written the book on the subject.

Professional foresters have long relied on the 135-page Service Forester’s Handbook for on-the-go access to the formulas, facts and figures they need. The pocket-sized weather-resistant field-guide helps foresters convert figures, calculate volumes and dozens of other key calculations.

Hulking above their neighbors in the Chattahoochee National Forest, Georgia’s century-old hemlocks are giants. But the relatively scarce, trees are quickly being felled by the tiniest of insects — the invasive hemlock woolly adelgid.

Looking back, it's easy to see where farmers in the 1800s went wrong. Attempting to grow profits from a lush environment, landowners cleared entire forests in the South to make room for agricultural farmland. But primitive agricultural techniques scarred the landscape, and when the profits dried up, they abandoned the barren land. Now University of Georgia researchers want to understand the ongoing repercussions of a bygone era.

Spring is around the corner, and University of Georgia Extension has a new app to help families and outdoor enthusiasts make the most of those first springtime hikes.

When we think of invasive species we usually think of insects, plants and animals that have been shipped to Georgia from another part of the world, but it’s a two-way street. Georgia’s native plants and insects can be just as devastating overseas if they take root in a foreign ecosystem

Georgia’s livestock producers may see higher profits in 2014 due to lower feed prices and higher consumer demand. However, those lower feed prices, and flat demand for corn for ethanol, may hold down profit margins for Georgia row crop farmers.

From time to time national news services pick up articles about someone who sold one walnut tree for thousands of dollars. This may stimulate the imagination of those who have large walnut trees in their landscape. These articles usually fail to mention that the tree was near a high quality hardwood veneer operation and had many burls that produce the most valuable veneer. The tree owner probably also guaranteed that there was no metal in the tree. No one living in Georgia can replicate this scenario.

Fraser firs top the list of favorite Christmas tree varieties, but almost all the Fraser firs sold in Georgia come from North Carolina. One University of Georgia horticulturist is working to change that by popularizing a hybrid that combines Fraser firs with their Japanese cousins — Momi firs.
