Slash conference at ElmiaWood 2 June 2009
Utilising forest residues collected after final fellings, mainly tops and branches (slash), is becoming increasingly popular in many regions. In the coming years we will also be able to use stumps and residues from thinnings – tops, branches and small trees. The technology to harvest forest residues is steadily developed by researchers and companies active in the field. At this seminar we ...

Greenhouse Gases Rise From Forests Damaged by Katrina
Losses inflicted by Hurricane Katrina on Gulf Coast forest trees are great enough to cancel out a year's worth of new tree growth in other parts of the country, according to a new study led by biologist Jeffrey Chambers of Tulane University. 'The carbon that will be released as these trees decompose is enough to cancel out an entire year's worth of net gain by all U.S. forests. And this is ...

Developing a digital tool for forestry planning
Planning for continuous cover forestry takes longer because the transport roads must be planned extremely carefully. Otherwise, there is a risk of blockages in waterways or damage to the roots of the unfelled trees. Having the machines going into the forest several times quickly inflates the budget. Furthermore, many people think they will need to use smaller machines, but this is not the case. ...

Reduced humidity seriously restricts leaf growth of beech trees
Beech trees are extremely sensitive to drought and are known to be one of the European tree species most at risk from climate change. New research found a dramatic reduction in the leaf growth of young beech trees growing in Central European forests when air conditions were dry, even where there was sufficient moisture in the soil. While previous experiments have shown the damaging effect of ...

Agroforestry can fix Pakistan’s depleting tree cover
Using a mix of trees and crop species can help rejuvenate Pakistan's deteriorating forests, a study reported. The study is based on physical and chemical analyses of 400 soil samples, collected during a survey of farms and plantations to compare the four agro-ecological zones of the Punjab province. Results of the findings published in the African Science Journal of Environmental Sciences and ...

Locally Cut Firewood Can Prevent the Spread of Invasive Pests and Create Substanial Savings For Communities
As fall turns into winter, people across the country buy or gather firewood to heat their homes, campsites, and cabins, and many aren't aware that moving firewood more than 50 miles can increase the risk of new invasive pest infestations that kill trees. A recent study, "Economic Impacts of Non-Native Forest Insects in the Continental United States" by Aukema et al. estimates that the costs of ...

Enterprise rent-a-car foundation to plant 5 millionth tree in 2010 as part of 50 million tree pledge with Arbor Day foundation and U.S. forest service
The Enterprise Rent-A-Car Foundation will plant its 5 millionth tree in 2010 as part of the 50 Million Tree Pledge, a private/public/nonprofit partnership between Enterprise, the Arbor Day Foundation and the U.S. Forest Service. For the fifth consecutive year since the program's launch in 2006, 1 million trees will be planted in national forests in countries in which Enterprise operates. ...

Slash-and-burn `improves tropical forest biodiversity`
Slash-and-burn agricultural practices, banned by governments because of the risk of uncontrolled fires, provide better growing conditions for valuable new trees than more modern methods of forest clearance, a study suggests. Starting in 1996, researchers cleared 24 half-hectare areas of tropical forest in Quintana Roo state, in southern Mexico, using three methods: clear-felling, where most of ...

Managed forests and renewable wood reduce greenhouse gases
Forests, and the wood-products they produce, can absorb or produce highly variable amounts of CO2, depending on how they are managed. New research provides guidelines for harvesting forests, while limiting greenhouse gas emissions. Wood is a renewable resource and the greatest environmental benefits from using wood occur when it is used first in the construction industry, and then recycled, if ...

Will tropical forests survive a changing climate?
Most people are familiar with tree-planting as a way to offset carbon emissions. However, while the focus has been on reforestation and preventing deforestation, there has been little emphasis on how the world's tropical forests, managed for production purposes, will actually be able to adapt to the changing climate. According to a new study, there is an urgent need to put measures in place to ...

On the path to net zero, Canada must grow a circular bioeconomy
Bathroom sinks made of wood fibre, energy derived from garbage, skyscrapers built of cross-laminated timber, and carbon fibre that is used in Formula 1 cars are all examples of bioproducts that are helping us replace the use of fossil fuels in our everyday lives. Today – July 7 – we are joining the World Bioeconomy Forum in celebrating World Bioproducts Day to raise awareness of the ...

Restoring the world`s forests while feeding the poor
“We are one shock away from a full-blown crisis,” stated Robert Zoellick, the president of the World Bank, at a recent meeting of the bank and the IMF. He was referring to a critical increase in poverty, resulting from the escalating cost of food. The UN’s food price index has risen 37% since March 2010. Basic cereal prices are up 60% over this period. Wheat is up 63%, and maize ...

Trees and farms working together: Agroforestry comes of age
Creating consumer markets for forest-grown products, reducing nonpoint source pollution, protecting waterfowl habitat, diversifying farm operations—these are just a few of the ways agroforestry is moving to the forefront of the land-use discussion in North America. A new edition of North American Agroforestry: An Integrated Science and Practice, published by the American Society of Agronomy ...

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 ...

North Korea lifts the veil on its agroforestry practices
A new study offers a rare glimpse into North Korea's agriculture and forestry policies, and may open up new international connections with the country, say researchers. The report describes how locally appropriate, participatory agroforestry is helping reverse food shortages and land degradation. According to Meine van Noordwijk, co-author of the study and chief science advisor at the ...
