Seals Reclaim California Beach During Shutdown
The government shutdown came to at least a temporary end Jan. 25, but one California beach is still dealing with its unexpected consequences. The popular Drakes Beach, part of the Point Reyes National Seashore, is now closed to human visitors after being overrun by elephant seals.
"In January 2019, elephant seals occupied the section of Drakes Beach adjacent to the Kenneth C. Patrick Visitor Center, and, at times, the parking lot and wooden ramps leading up to the visitor center. As a result, the entire Drakes Beach area south of the junction of Sir Francis Drake Boulevard and Drakes Beach Road was closed to the public to better protect the elephant seals from disturbance," the seashore announced.

While most of the shutdown's impacts on national parks have been disastrous for wildlife and visitors, the reclamation of the beach by nearly 100 female seals and pups, as well as a few males, has actually given returning park staff hope.
"If you just get out of the way, wildlife will find their way in," chief seashore wildlife ecologist Dave Press told The Guardian.
Head of interpretation and resource education at Point Reyes John Dell'Osso said that, during the shutdown, the seashore's usual staff of around 85 was reduced to around 12. That meant that there were not enough employees to carry out the usual strategies to discourage seals from occupying the popular Drakes Beach, like shaking blue tarps.
Weather was also a factor, Dell'Osso told USA Today, as heavy rain flooded a parking lot and high, king tides inundated the beaches. This combination of factors, along with the lack of staff, encouraged the seals to claim the beach. Dell'Osso said that more than 40 females, around 35 pups and 10 males were now living there.
To protect the sensitive pups, seashore employees are keeping humans off the beach itself, but that doesn't mean the situation is a total loss for visitors.
"However, this weekend we are experimenting by opening the road and parking lot back up, closing a small portion of the lot closest to the beach (maybe 20 cars or so), and stationing Park Rangers and docents to guide people to the edge of the parking lot for incredible viewing opportunities, but no access on the beach," Dell'Osso told USA Today. "Based on how this works for both visitor safety and protection of the seals, we may continue this the following weekend."

If the strategy works, Dell'Osso told The Guardian, these weekend viewing sessions could continue through early April, when the pups will have been weaned and the seals will move on.
Elephant seals are a conservation success story. They were almost hunted to extinction in California, The Guardian reported, but have since staged a comeback. The first pup within decades was born along the Point Reyes seashore in the 1980s.

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:firstname.lastname@example.org" 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.
