Fall Linkfest


Stoke up your outdoor experience with these autumnal tree links

Planting is the most rewarding time to plant trees, and these guys agree with me:

• Augusta Chronicle planting article
• Bill Lamson-Scribner of the Charleston Courier - article meanders a bit, just read the last paragraph
• Lee Reisch at the Hickory Record.
• Even the Canadians agree.

Walter Reeves answers a question about planting Japanese maple seeds.

Fall color is soon to reach its peak here in Atlanta, judging from this article at The Franklin Press Online (NC).

How to Identify Georgia Trees (What Kind of Tree is THAT?)


Puzzled by the staggering legions of oaks, hickories, and little shrubby things in Atlanta's forests, nature enthusiasts and professional arborists alike have been caught more than once scratching heads and cramping necks in an attempt to identify a favorite tree.

Trees of Georgia and Adjacent States, by Brown and Kirkman, has been helping would-be-dendrologists solve this problem for decades. It is a well researched, crisp tome, that is also easily digested. The book succeeds because it has one major goal: to serve as a resource in identifying the species of native trees and woody plants in Georgia and the Southeastern US.

Special features of the book:

Dichotomous key (although it is worded a bit too concisely)
• Winter key to flowering trees
• Leaf, leaf scar, bud, flower and fruit diagrams
• Color photographs of leaves, flowers, fruit, and bark
• Tree descriptions
• Explanations of the difficulties in specific species recognition (is it Black willow or Coastal plain Willow?)
• Range maps

Trees Squelch Bad Odors

New research shows that trees can reduce emissions of dust, ammonia, and odors near poultry farms. In some cases, the emissions were cut by almost half.

The study was presented at the 236th National Meeting of the American Chemical Society (ACS).

The report suggests that planting vegetation could reduce ammonia and particulates that degrade air and water quality. Research began in 2000, when residents near poultry farms in Maryland and Virginia complained about nasty odors from chicken houses. The research lead, Dr. George W. Malone of the University of Delaware said "We were aware of the concerns locally. We looked at what we could do to address them and the whole area of air quality as it relates to the emission of ammonia from poultry houses."

Researchers proposed planting trees to serve as a filter. In this six-year study, Malone found that a three-row plot of trees of various species and sizes reduced total dust by 56%, ammonia 53%, and odor 18%.

Not all trees function the same. In the Delaware area, Malone recommends the first row of trees be either a deciduous tree or one with a waxy leaf, and the other two rows be an evergreen.

The trees also improve water quality around farms because they can filter pollutants from soil and groundwater.
