Mixed species growth predictions made easy – well, easier
A recent study indicates why it is difficult to predict how mixed-species forests or plantations will grow, but makes those predictions easier by discussing the processes that drive changes over space and time in species interactions.
Since tree species mixtures are regarded as one of the most important approaches to reduce the risks to forests posed by global change, the study’s conclusions will be of interest to forest managers or policy makers using mixed-species forests or plantations.
Entitled The spatial and temporal dynamics of species interactions in mixed-species: From pattern to process, the study is by Dr. David Forrester, Chair of Silviculture, Faculty of Environment and Natural Resources, Freiburg University.
Got a question? Biomass may be the answer
It’s just possible that sustainable biomass could be, if not a panacea for the world’s energy challenges, then perhaps the next best thing.
And not only the energy sector would benefit. The reasons for the sustainable use of biomass are many and good, says Dr Viktor Bruckman of the Commission for Interdisciplinary Ecological Studies at the Austrian Academy of Sciences.
In addition to the energy aspect, he adds that biomass offers a range of possibilities as a valuable feedstock for industrial processes. Chemical compounds in biomass can be separated and rearranged to produce everything from composites for use in the automobile industry, to fibres to pesticide ingredients, among others.
Eucalyptus genome successfully sequenced
With a result that offers major potential for the forest industry, an international team of researchers has successfully sequenced and analyzed the genome of Eucalyptus grandis.
“Now that we understand which genes determine specific characteristics in these trees, we will be able to breed trees that grow faster, have higher quality wood and use water and land more efficiently,” said the lead investigator on the project, Prof. Zander Myburg of the University of Pretoria, South Africa.
Green cities: The benefits of the urban forest
The urban forest means different things to different people.
Many of us see only visually pleasing tree-lined streets, or enjoy the coolness afforded by shade trees on hot days.
Those more closely involved with the urban forest see that – and much, much more.
They also see the urban forest in terms of the ecosystem services and values derived from it – reduced energy use of buildings, improved air quality, stream flows, water quality, urban wildlife, human health, climate change (in terms of both mitigation and species composition) and other benefits that are environmental, social and economic.
The forest pharmacy and food store
Sometimes, they say, you can’t see the forest for the trees.
And one group of sub-plenary session organizers for the upcoming IUFRO World Congress in Salt Lake City might amend that to read: “Sometimes you can’t see the forest for anything but the timber value in the trees.”
The organizers – Hannu Raitio and Tuija Sievänen of the Finnish Forest Research Institute; James Chamberlain of the U.S. Forest Service; and Carsten Smith-Hall of Denmark’s University of Copenhagen, will present a session entitled: The value and challenges of integrating food and medicinal forest products into forest management.
The climate’s changing: So should forest management
As a joke, people used to say: “If you don’t like the weather, just wait a minute. It’ll change.”
Now they say that about the climate – but they’re a lot more serious.
The rapidly changing climate will precipitate related changes throughout nature. And that includes the world’s forests.
Anticipating climate change impacts on forests and adapting policies and management strategies to mitigate those impacts is critical to maintain the health of those forests and, by extension, of the earth.
“Forest management for adaptation to climate change” is the theme of a session being presented at the 24th IUFRO World Congress in Salt Lake City this fall, by Drs. Rodney Keenan of the University of Melbourne, Australia; Carina Keskitalo of Umeå University, Sweden; Kalame Fobissie of the World Wildlife Fund Central Africa, Cameroon; and Guangyu Wang of the University of British Columbia, Canada.
‘Citizen science’: A way to fight invasive species?
Invasive species are a threat to forest ecosystems around the world.
No surprise there.
Thousands of invasive flora and fauna have been transported – sometimes by accident, sometimes by design – to different continents and countries. Very often their impact is detrimental to their new region.
But, usually when one thinks of the negative impacts of invasive species, top of mind would be the effect on the economy – for instance, phytophthora dieback, an Asian import, affects the economically important jarrah tree in Australia. Or perhaps one would think of environmental damage, such as the destructive swath cut through the forests of Tierra del Fuego by imported North American beaver, to give just two illustrations of unwanted economic/environmental results.
Consumers and Industry: Keen on Green
Looking toward the future is enough to make you, ahem, “turn green” with envy.
It’s all about a greener future.
That future and, more specifically, how it relates to the world’s forests will be one of many subjects discussed at the XXIV IUFRO World Congress in Salt Lake City, Utah, this fall.
A session there, entitled Forests and Forest Products for a Greener Future will look at how business and marketing will contribute to that goal.
Organized by Eric Hansen of Oregon State University, Tom Hammett of Virginia Tech and Birger Solberg of the Norwegian University of Life Sciences, it will cover a wide range of business and marketing theory topics that address how products and markets (timber and non-timber) can be expected to contribute to the greening effect.
Forest outlook: What does the future hold?
Forest researchers from around the world will gather at the IUFRO 24th World Congress in Salt Lake City this fall where one of the issues will be to address the future, and the related challenges, facing forests and forest management in the 21st century.
Providing a sort of scientific crystal ball to give glimpses into the years ahead and discuss how to meet and adapt to coming challenges will be a sub-plenary session at the congress entitled, appropriately enough, “The Future of Our Forests”.
Resources for the Future (http://www.iufro.org/science/task-forces/resources-for-future/), the IUFRO Task Force behind this session, has set out to examine four major game-changers – globalization, plantations, new products and forest ecosystem services – and what they mean, and will mean, for forests, forest research and forest-dependent communities.
Planted forests’ roles: Different strokes for different oaks
Planted forests are vital but vulnerable resources that can contribute in a sustainable fashion to some of humanity’s most pressing needs – poverty alleviation, food security, renewable energy, mitigation of and adaptation to climate change, and biodiversity conservation – as well as the preservation of natural forests.
These are among the findings in the recently published Summary Report of the 3rd International Congress on Planted Forests. It is based on outcomes from three scientific workshops and a plenary meeting that took place earlier this year.
Thirty-three countries have greater than 1 million hectares of planted forest area. Together these countries comprise 90% of the world’s 264 million hectares of planted forest which, in turn, equals almost 7% of the total global forest area. The report takes into account key research findings from Africa, Asia, Europe, Oceania, Latin America and North America related to vulnerability, viability and governance of planted forests.
