Terrestrial Laser Scanning to measure forest parameters
In November landConsult completed the second service contract with a national forest adminisitration in eastern Germany. Using a FARO Focus 3D Scanner and a Stonex GNSS more than 5 heactares with thousands of broadleaf trees and conifers have been scanned. All scanned forests are part of a permanent monitoring system to research tree quality and ecological parameters. The 3D modells are stored ...

Climate shift `killing US trees`, according to new study
Tree death rates have more than doubled over the last few decades in old-growth forests of the western United States, and the most probable cause of the worrisome trend is regional warming, according to a U.S. Geological Survey-led (USGS) study published in Science on January 23. The study found that the increase in dying trees has been pervasive. Tree death rates have increased across a wide ...

Drones effective tools for fruit farmers
People have used the phrase “drone on and on” for a long time. Webster’s dictionary defines this figure of speech as “to speak for a long time in a dull voice without saying anything interesting.” Yet, in agriculture, drones aren’t dull, at all! Farmers use drones to be more efficient. Drones help farmers improve yields and stay ahead of problems before they ...

Peroxide UltraPure™ produced directly on site improves growth and yield in super-intensive olive plantation
The Alentejo region in Portugal is known for its long sunny days, which create ideal conditions for the growth of high-quality olives. Irrigation water in the region is sourced from the Alqueva dam, and especially in the summer months it accumulates a high quantity of organic matter (algae, bacteria). This caused a problem for growers in the region specifically with drippers clogging, irrigation ...

Researchers use steam to treat citrus greening
University of Florida researchers are turning to the old-fashioned method of steaming to help treat citrus greening, a disease devastating citrus trees throughout Florida. Reza Ehsani and his UF Institute of Food and Agricultural Sciences colleagues are tenting and then enveloping trees in steam that is 136 degrees Fahrenheit for about 30 seconds in an attempt to kill the citrus greening ...

New tool to improve assessment of forest biomass and carbon stocks
A new online platform launched by FAO will allow countries to improve the assessment of forest volumes, biomass and carbon stocks. This data is crucial for climate change research and mitigation activities, such as increasing the carbon stock in forests through reforestation, and bioenergy development. The new GlobAllomeTree, jointly developed by FAO, the French Research Centre CIRAD and Tuscia ...

Careful urban tree planting and pruning needed to reduce trapping of air pollution
Careful planting and pruning is needed to ensure that air pollution in tree-lined streets is minimised, new research suggests. While planting trees in urban areas can have many benefits, such as enhancing biodiversity, trees can trap particulate matter pollution, say the study’s authors. Particulate matter (PM) air pollution is a component of vehicle exhaust emissions and PM2.5 (particles ...

European trees planted in China to identify potentially invasive species in our forests
Most of the exotic species which attack plants in Europe now come from Asia. INRA scientists, together with teams from the Academy of Sciences in Beijing and the Forestry University in Zhejiang have devised a new method for detecting potential invaders in their region of origin before they are introduced on another continent. European sentinel trees were planted in China for four years, and ...

Book Byte: We Can Reforest the Earth
Protecting the 10 billion acres of remaining forests on earth and replanting many of those already lost are both essential for restoring the earth’s health. Since 2000, the earth’s forest cover has shrunk by 13 million acres each year, with annual losses of 32 million acres far exceeding the regrowth of 19 million acres. Restoring the earth’s tree and grass cover protects ...
