Join Omega Institute's 'Seeds of Change: Cultivating the Commons' Conference Oct. 9 - 11
Over the past decade, presenters and participants at the Omega Center for Sustainable Living's conferences have brought together a group of thinkers, activists and enthusiasts all working on the interconnected issues central to creating a more regenerative future. These conversations have begun creating a compelling and hopeful vision for a socially just, inclusive and sustainable society.
This year the conversation continues with Seeds of Change: Cultivating the Commons.
Viewing our environmental, economic and social challenges through the lens of the commons allows us to more easily see how their solutions are connected. As renowned eco-feminist Vandana Shiva says, the commons is more than just resources, “the commons is the web of life."
The commons, Omega CEO Skip Backus says, helps “instill an understanding and awareness of the value of both natural and cultural resources we all share."
This shift in awareness, Backus adds, “is crucial in helping bring about the sort of cultural shift we need, a shift away from consumption and depletion and toward regeneration."
Vandana Shiva will be joined at Seeds of Change by orator and author Winona LaDuke; water advocate Maude Barlow; consumer activist and political commentator Ralph Nader; ecological visionary John Todd and grassroots seed freedom and food justice campaigners Will Allen, Natasha Bowens, Ken Greene and Jalal Sabur.
Whether you are already working closely with these issues or are interested in learning more, we invite you to be part of a growing community coming together to protect and care for the commons, including the pivotal right to save and share seeds, the necessity of stewarding our water resources, as well as transparency in labeling and access to healthy food.
If you can't visit Omega's Rhinebeck, New York campus for the conference, the Sunday session of Seeds of Change: Cultivating the Commons will be live streamed, from 9:30 a.m. to 12:30 p.m. ET, Oct. 11. Registration will allow you to view this session through Nov. 11.

On his first day in office President Joe Biden started signing executive orders to reverse Trump administration policies. One sweeping directive calls for stronger action to protect public health and the environment and hold polluters accountable, including those who "disproportionately harm communities of color and low-income communities."
Michael S. Regan, President Biden's nominee to lead the U.S. Environmental Protection Agency, grew up near a coal-burning power plant in North Carolina and has pledged to "enact an environmental justice framework that empowers people in all communities." NCDEQ

Clear-cutting a forest is relatively easy—just pick a tree and start chopping. But there are benefits to more sophisticated forest management. One technique—which involves repeatedly harvesting smaller trees every 30 or so years but leaving an upper story of larger trees for longer periods (60, 90, or 120 years)—ensures a steady supply of both firewood and construction timber.
A Pattern in the Rings<p>The <a href="https://www.encyclopedia.com/science/dictionaries-thesauruses-pictures-and-press-releases/coppice-standards-0" target="_blank">coppice-with-standards</a> management practice produces a two-story forest, said <a href="https://www.researchgate.net/profile/Bernhard_Muigg" target="_blank">Bernhard Muigg</a>, a dendrochronologist at the University of Freiburg in Germany. "You have an upper story of single trees that are allowed to grow for several understory generations."</p><p>That arrangement imprints a characteristic tree ring pattern in a forest's upper story trees (the "standards"): thick rings indicative of heavy growth, which show up at regular intervals as the surrounding smaller trees are cut down. "The trees are growing faster," said Muigg. "You can really see it with your naked eye."</p><p>Muigg and his collaborators characterized that <a href="https://ltrr.arizona.edu/about/treerings" target="_blank">dendrochronological pattern</a> in 161 oak trees growing in central Germany, one of the few remaining sites in Europe with actively managed coppice-with-standards forests. They found up to nine cycles of heavy growth in the trees, the oldest of which was planted in 1761. The researchers then turned to a historical data set — more than 2,000 oak <a href="https://eos.org/articles/podcast-discovering-europes-history-through-its-timbers" target="_blank" rel="noopener noreferrer">timbers from buildings and archaeological sites</a> in Germany and France dating from between 300 and 2015 — to look for a similar pattern.</p>
A Gap of 500 Years<p>The team found wood with the characteristic coppice-with-standards tree ring pattern dating to as early as the 6th century. That was a surprise, Muigg and his colleagues concluded, because the first mention of this forest management practice in historical documents occurred only roughly 500 years later, in the 13th century.</p><p>It's probable that forest management practices were not well documented prior to the High Middle Ages (1000–1250), the researchers suggested. "Forests are mainly mentioned in the context of royal hunting interests or donations," said Muigg. Dendrochronological studies are particularly important because they can reveal information not captured by a sparse historical record, he added.</p><p>These results were <a href="https://www.nature.com/articles/s41598-020-78933-8" target="_blank">published in December in <em>Scientific Reports</em></a>.</p><p>"It's nice to see the longevity and the history of coppice-with-standards," said <a href="https://www.teagasc.ie/contact/staff-directory/s/ian-short/" target="_blank">Ian Short</a>, a forestry researcher at Teagasc, the Agriculture and Food Development Authority in Ireland, not involved in the research. This technique is valuable because it promotes conservation and habitat biodiversity, Short said. "In the next 10 or 20 years, I think we'll see more coppice-with-standards coming back into production."</p><p>In the future, Muigg and his collaborators hope to analyze a larger sample of historic timbers to trace how the coppice-with-standards practice spread throughout Europe. It will be interesting to understand where this technique originated and how it propagated, said Muigg, and there are plenty of old pieces of wood waiting to be analyzed. "There [are] tons of dendrochronological data."</p><p><em><a href="mailto:email@example.com" target="_blank" rel="noopener noreferrer">Katherine Kornei</a> is a freelance science journalist covering Earth and space science.

Earth's ice is melting 57 percent faster than in the 1990s and the world has lost more than 28 trillion tons of ice since 1994, research published Monday in The Cryosphere shows.
