UGA Radon Program
University of Georgia Cooperative Extension’s radon testing program — a holistic program that combines radon education outreach with research, testing and mitigation — has helped optimize sampling and testing methodology for radon in water throughout the U.S. The program has influenced national standards in radon testing.
A new $1.5 million grant from the National Oceanic and Atmospheric Administration (NOAA) will help UGA scientists delve into the dynamics of coastal Georgia wetlands, researching how collapsing marshes can affect property values and storm resiliency in coastal communities. CAES News
Balancing Act
The forces at work in a marsh require a delicate balancing act. Rising and falling tidewaters keep clumps of Spartina grasses from growing too dense. But too much water makes it difficult for them to survive. Tip this balance too far in either direction and the marsh ecosystem collapses, resulting in a population of different plants — or no plants at all.
To support efforts to isolate genes responsible for water intake, Aggrey and Rekaya have been awarded a grant through the U.S.-Egypt Science and Technology Joint Fund to pursue a project titled “Improving the Efficiency of Water Intake Utilization in Poultry.” CAES News
Water Scarcity
With nearly 2.5 million employed in an industry that produces 1.1 billion broilers per year, Egypt’s poultry industry is booming. Because of its dry climate, however, the country’s production levels are heavily reliant on producers’ ability to use resources efficiently without compromising output.
After molting into adults, periodical cicadas will move or fly to nearby vertical structures, especially shrubs and trees. The females will eventually lay their eggs on the ends of tree branches. CAES News
Tree Flagging
The emergence of Brood X exceeded expectations in north Georgia, as those of us who happen to reside in the “cicada zone” observed droves of periodical cicadas during the peak of the event. Over the past weeks, the song of the male periodical cicada has faded and fewer of these fascinating insects remain, but a sign of their passing is still evident.
A water rescue crew searches for survivors in Texas after Hurricane Harvey, a devastating Category 4 hurricane that made landfall on Texas and Louisiana in August 2017, causing catastrophic flooding. CAES News
Flood Insurance Risk
Fifteen million homes in the United States are at risk of flooding, according to the nonprofit First Street. And homes on the coasts aren’t the only properties at risk.
Common seasonal pests like (clockwise from top right) fire ants, houseflies, brown marmorated stink bugs and mosquitos (shown in standing water as larvae) can be controlled with simple tips from UGA Cooperative Extension. CAES News
Summer Pests
As a University of Georgia Cooperative Extension agent, I see a lot of insects. People leave jars of them on my desk, send me photos or call me out to their gardens to identify them and give control recommendations.
Blubaugh Lab manager Katherine Hagan and master’s student Allison Stawara scout squash for various beneficial and pest insects as part of a living mulch study at the Durham Horticulture Research Farm in Watkinsville, Georgia. CAES News
Organic Pest Control
The hot, humid climate in the Southeast lends itself to nearly year-round insect, weed and disease pressure, and growing is especially tough if you’re an organic farmer.
UGA Weather Network Director Pam Knox checks one of the data-logger boxes maintained by the network. All of the observational instruments connect to the data-logger, which collects and transmits weather data at 15-minute intervals, which is then disseminated through the UGA Weather Network website.

UGA Weather Network
On June 1, 1991, the first agricultural weather station operated by the University of Georgia began transmitting data from Griffin, Georgia. Since then, the UGA Weather Network has grown to include 87 stations scattered across the state, providing weather data to a variety of users. On June 1 this year, this 30-year record of continuous weather data makes the UGA Weather Network one of the oldest state weather networks in the country.
In the sculptured resin bee (left), females have a pointed abdomen, while the males have a blunt edge. Both males and females have a striated abdomen with raised bands. The thorax and abdomen of the carpenter bee (right) are connected, bald and smooth. CAES News
Sculptured Resin Bees
University of Georgia entomologists are seeking citizen help to document the presence of the sculptured resin bee — also known as the giant resin bee — an invasive bee that could threaten the native carpenter bee population.
Most of the U.S. was warmer, and the eastern two-thirds of the contiguous U.S. was wetter, from 1991–2020 than the previous normals period, 1981–2010. With 20 years of overlap between the current normals and the previous iteration (1991–2010), annual changes between these two data sets were somewhat muted compared to trends over the same period. Monthly and seasonal changes are more dynamic. For example, the current normals for the northern-central U.S. are cooler in the spring, while much of the Southeast is now warmer in October, cooler in November and warmer again in December. Atmospheric circulation dynamics and surface feedbacks result in substantial differences from month to month and region to region. CAES News
New Normals
Day-to-day swings in temperature are an accepted part of the weather in many areas around the country. However, when 30-year averages of daily temperature fluctuations from thousands of stations around the country indicate a steady change in average temperatures over time, there are tangible implications for agriculture, energy consumption and many other aspects of daily life.
