100 Years of National Parks : Famous Yellowstone jumps in visitors equals concerns over wildlife and safety

When things go well – and people connect with Nature – the unforeseen consequences can be hard to handle…isn’t that ironic!? For starters: the park has hired Mandarin-speaking park rangers to communicate with the increasing number of Chinese visitors.

Park rangers reassess how to manage tourist violations, staff burnout and ‘animal jam’ as number of national park guests peaked to four million last year  

The Guardian reports: Yellowstone national park is finding new ways to manage tourism after visits jumped by almost 600,000 between 2014 and 2015. After 15 years of steady growth, last year’s 4m visits was a tipping point, says park ranger Charissa Reid.

The park expects the number to rise in 2016. July is likely to be the first million-visit month in the park’s 144-year history.

However, extra visitors have increased accidents between humans, animals, and the park’s flora and fauna.

Park rangers issued more than 52,000 resource violations last year. People broke thermal features, interacted with protected wildlife and relieved themselves in the park. DUIs and domestic violence inside the park also increased.

The number of full-time staff at Yellowstone has remained static for over a decade, adding to problems. The NPS employed only 330 permanent and 406 seasonal Yellowstone staff last year.

Some incidents have made headline news – a man who strayed 225 yards off a designated path and fell to his death in Yellowstone’s Norris geyser basin and five people were gored by bison. However, dying in Yellowstone is unlikely.

“When you consider we had 4 million visitors, I think we’re doing pretty good,” says Reid.

Managing human behavior to maintain safety, prevent staff exhaustion and keep visitors happy is a daily challenge.

A common disruptive human behavior at Yellowstone is an “animal jam”. This happens when people see a bear or a buffalo, or any other animal, and come to a full stop to jump from their cars.

“We can always tell the difference between a bison jam and a bear jam, because at a bear jam doors are flung open,” says Reid. “People kind of lose it over bears in the park.”

Yellowstone needs better understanding of visitor behavior to help with management, says Reid.

Animal biologists, law enforcement and printers in Yellowstone’s sign shop are all involved in visitor management. “We are trying to engage everyone to find solutions,” says Reid.

Yellowstone has also hired a social scientist to study humans. He researches how visitors enter and exit through the park, and how they interact with park attractions.

“Our superintendent often says visitors are the least studied mammal in Yellowstone,” says Reid. “We know more about bison biology than we know about park visitors.”

Increasing international visitors, use of social media and varied cultural expectations among visitors have all caused problems.

The park has hired Mandarin-speaking park rangers to communicate with the increasing number of Chinese visitors. Animal warnings have been translated into 10 languages and more toilets have been installed. New barriers and signs stop tourists from wandering, and protections outside wolf and wildlife dens keep them safe.

Reid acknowledges these are short-term solutions. Effective long-term solutions remain beyond park management’s immediate control, buried in budgets, and stored in as yet unmined visitor data.

In the meantime, visitors are part of the solution….. read the full article here

Today on Montessori’s birthday – we recall a force for good, where children can and do interact with their environment. Was this the birth of  environmental education – NAEEUK?

Maria Montessori (August 31, 1870 – May 6, 1952) was an Italian physician and educator, a noted humanitarian and devout Catholic best known for the philosophy of education that bears her name. Her educational method is in use today in public and private schools throughout the world.

In this first classroom, Montessori observed behaviors in these young children which formed the foundation of her educational method. She noted episodes of deep attention and concentration, multiple repetitions of activity, and a sensitivity to order in the environment. Given free choice of activity, the children showed more interest in practical activities and Montessori’s materials than in toys provided for them, and were surprisingly unmotivated by sweets and other rewards. Over time, she saw a spontaneous self-discipline emerge.[26]

Based on her observations, Montessori implemented a number of practices that became hallmarks of her educational philosophy and method. She replaced the heavy furniture with child-sized tables and chairs light enough for the children to move, and placed child-sized materials on low, accessible shelves. She expanded the range of practical activities such as sweeping and personal care to include a wide variety of exercises for care of the environment and the self, including flower arranging, hand washing, gymnastics, care of pets, and cooking. She continued to adapt and refine the materials she had developed earlier, altering or removing exercises which were chosen less frequently by the children. Also based on her observations, Montessori experimented with allowing children free choice of the materials, uninterrupted work, and freedom of movement and activity within the limits set by the environment. She began to see independence as the aim of education, and the role of the teacher as an observer and director of children’s innate psychological development.

Darwin’s tree of life brought into the future

A new project aims to bring Charles Darwin’s masterclass on evolution into this century. Carl Zimmer of The New York Times reports

A tree of life connects species 

In 1837, Charles Darwin opened a notebook and drew a simple tree. Each branch represented aspecies. In that doodle, he captured his newfound realization that species were related, havingevolved from a common ancestor. Across the top of the page he wrote, “I think.”

Two decades later Darwin presented a detailed account of the tree of life in “On the Origin ofSpecies.” And much of evolutionary biology since then has been dedicated to illuminating parts ofthe tree. Using DNA, fossils and other clues, scientists have worked out the relationships of manygroups of organisms, making rough sketches of the entire tree of life.

“Animals and fungi are in one part of the tree, and plants are far away in another part,” said LauraA. Katz, an evolutionary biologist at Smith College in Northampton, Massachusetts.

Now Dr. Katz and her colleagues are doing somethingnew: they are drawing a tree of life that includes everyknown species – a tree with about two million branches.

“I think it is an amazing step forward for our communityif it can be pulled off,” said Robert P. Guralnick, an expert on evolutionary trees at the University of Colorado who is not part of the project.

Until recently, a complete tree of life would have beeninconceivable. To figure out how species are related,scientists inspect each possible way they could berelated. With each additional species, the total numberof possible trees explodes. There are more possible trees for just 25 species than there are stars.

But scientists have developed computer programs thatfind the most likely relationship among species without considering every possible arrangement. Thosecomputers can now analyze tens of thousands ofspecies at a time.

Yet these studies have thrown spotlights on only smallportions of the tree of life.

“Nobody has tried to put all these results together,” saidthe leader of the new effort, Karen Cranston, a biologistat the National Evolutionary Synthesis Center in Durham, North Carolina.

Last year, Dr. Cranston and other experts came up witha plan for a single tree of life. The National Science Foundation has awarded the team a three-year grant of$5.7 million. The project, the Open Tree of Life, hopes to publish a draft by August 2013. The scientists willgrab tens of thousands of evolutionary trees archived online, then graft the smaller trees into a single big one.

These trees represent just a tiny fraction of all known species. The rest are classified in the oldLinnaean system, in which they are assigned to a genus, a family, a kingdom, and so on. The teamwill use that data too. All the species in a genus, for example, will belong to branches descendingfrom the same common ancestor. The Linnaean system will give the tree only a rough picture ofthe true relationships among species.

“Parts of it will be quite good, and parts will be quite bad,” Dr. Cranston said.

The team will then set up an Internet portal where the entire community of evolutionary scientistscan upload new studies, which can then automatically revise the entire tree.

And the tree will grow. Each year scientists publish descriptions of 17,000 new species. Last yeara team estimated the total number of species to be 8.7 million, although others think it could easilybe 10 times that.

When scientists publish the details of a new species, they typically compare it with known speciesto determine its closest relatives. They will be able to upload this new information into the OpenTree of Life. Scientists who extract DNA from the environment from previously unknown species willbe able to add their information as well.

Animals and plants will take up only a tiny part of the tree. “Most biodiversity on earth is microbial,”said Dr. Katz.

Microbes pose a special challenge. The branches of the tree of life represent how organisms passtheir genes to their descendants. But microbes also transfer genes among one another. Thosetransfers can join branches separated by billions of years of evolution.

“In a lot of the tree of life, it’s not really treelike,” Dr. Cranston said.

She and her colleagues are exploring how they can build their database to include these genetransfers, and how best to visualize them.

“That’s an issue we intend to struggle with for the next three years,” Dr. Katz said.

Luke Harmon, an evolutionary biologist at the University of Idaho who is not involved in the project,looks forward to using the tree to explore the history of life. One major question evolutionarybiologists have long explored is why evolution runs at different speeds in different lineages.

 

A tree of life connects species

“We can use the tree to identify evolutionary ‘bangs’ and’whimpers’ through the history of life,” said Dr. Harmon said. It may also be possible to see how climate change has driven extinctions, and to make predictions for the future.

Stephen A. Smith, a team member from the University ofMichigan, hopes that the Open Tree of Life will allowscientists to tackle some major questions.

The tree may be able to guide the search for new drugs,for example. Scientists trying to treat infectious bacteria could search for the fungi that makeantibiotics that are effective against it. The relatives of those fungi might make even more effectivedrugs.

“These are questions we can ask now,” Dr. Smith said. “But we don’t have all the data together toanswer them yet.”

Roderic D. M. Page, a professor of taxonomy at the University of Glasgow, called the Open Tree ofLife team “first class,” but added: “Displaying large trees is a hard problem that has so far resistedsolution. We are still waiting for the equivalent of a Google Maps.”
