Black Forest Giants captured in 3D
Terrestrial Laser Scanning opens new perspectives into the forest ecosystem, no matter if you want to use it to precisely locate and measure landscape objects or if you want to present the Genius Loci of a Plenterwald with audio-visual effects as demonstrated in this example. http://youtu.be/RhV_T6zYxhk The video clip has been generated from Terrestrial Laser Scanning data of some 150 - 200 ...

Katam launches the world’s first service for capturing tree trunk data using camera drones
A new service offered by Katam Technologies utilises autonomous drones to complement manual measurements of tree trunk diameter. With this new solution, forest owners and field personnel can avoid entering inaccessible, hilly, thorny, and even dangerous forests, such as tropical environments that are home to spiders and snakes. Traditionally, drones are used in forestry by flying above the tree ...

Promoting small-scale planting of trees in dryland areas
This policy brief, published by the research network NCCR North-South, argues for policies that promote planting trees in drylands on a small scale, because large-scale projects can negatively affect local ecosystems. International aid agencies and governments have been promoting large-scale planting for more than a century. But the practice is becoming increasingly controversial. Advocates say ...

FAO sets standards to improve national forest monitoring systems
FAO has launched free software tools that it hopes will improve the way many developing nations monitor the state of their forests to tackle deforestation and climate change. The tools are designed to assist countries through the entire lifecycle of a forest inventory - from assessment, design and field data collection to analysis and reporting. The governments of Finland and Germany have ...

Growth-oriented logging: a new concept in forest management
Deforestation in the tropics has both local and global effects, but conservation remains a major challenge. New research describes a method for measuring tree growth and timber harvesting, which can lead to sustainable management of tropical timber resources. The method tailors cutting cycles according to accurate growth rates of different tree species. Research explored the Mamirauá Sustainable ...

Bees in the city: urban environments could help support pollinators
Urban areas may support higher levels of bee diversity than expected, new research has shown. The UK-wide study compared three different habitat types — nature reserves, farmland, and urban areas — and found a higher number of different bee species in urban areas than farmland. However, the overall pollinator diversity, which included species of bees, flies, hoverflies and ...

Model predicts shifts in carbon absorption by forest canopies
An Agricultural Research Service (ARS) scientist participated in a project to fine-tune computer models that can indicate when forest 'carbon sinks' become net carbon generators instead. The results will help pinpoint the effectiveness of trees in offsetting carbon releases that contribute to higher atmospheric temperatures and global climate change. ARS plant physiologist Erik Hamerlynck ...

Rising heat brings earlier vintage
Global warming has begun to change the conditions for a fine wine harvest. The grapes are blooming earlier in Burgundy. The vintners of Vaud in Switzerland have a new harvest timetable. And the conditions for fine claret have altered in Bordeaux. Two US scientists have analysed 400 years of harvest data from France and Switzerland to confirm that, while climate change has not yet created ...

Land users are positive about long-term benefits of sustainable practices
The costs and benefits of sustainable land management have been collated in a new review. Data from a global archive was analysed for the costs of sustainable practices and technologies and for land users' perceptions of cost–benefit ratios. Most respondents had a positive view of the short-term cost-benefit ratio, and a strongly positive view of the long term. Low upfront costs, long-term ...

Management Strategies to Reduce Catfacing in Peaches
For producers of peaches and other orchard-grown produce, managing the orchard floor can present challenges. Unwelcome vegetation on the orchard floor competes with trees for water and nutrients reducing tree growth and productivity, and can be a host for pathogens and insect pests. Utilizing best practices for irrigation and vegetation management in the orchard helps growers to optimize tree ...
