The below-normal temperatures across Iowa the last week or so have done a good job freezing many of the state’s smaller lakes and ponds.

Iowa DNR Fisheries Chief Joe Larscheid says that means the ice should be thick enough for activities like skating or fishing, especially in the northern part of the state.

“We’ve got a good solid five to ten inches across Iowa, the more north you go, the better the ice. Up north I don’t see any problems,” he says.  “If ice just recently formed in southern Iowa, that would be the places to be careful of."

As temperatures begin to fall past zero in Iowa, it’s hard to believe that for some birds, especially birds of prey, Iowa is a southerly destination when it comes to migration.

“There are some that are coming from the arctic, there are some that are coming from the boreal forests,” Says wildlife biologist Jim Pease. “But in general, if we think of raptors, owls tend to stay, hawks tend to move, and eagles do both.”

For snowy owls, Iowa can provide food sources that their usual arctic homes cannot.

On this River to River segment, host Ben Kieffer interviews scientist and ecologist Ari Friedlaender, who has been working in Antarctica for about 20 years. 

During the course of his more than 25 trips to the continent, he has developed a long-term ecological research program that has led to many important discoveries about whales in that polar region.

He is an associate professor at Oregon State University’s Marine Mammal Institute, and he is featured in a new National Geographic documentary titled CONTINENT 7: ANTARCTICA.

Protesters gathered at the offices of the Iowa Utilities Board on Monday to celebrate the Army Corps of Engineers stopping pipeline construction in North Dakota. Iowa’s Bakken Pipeline Resistance Coalition also delivered a letter to the state utilities board, urging it to revoke the pipeline’s Iowa permit. 

The Army Corps’s decision to not allow the pipeline to cross a reservoir near the Standing Rock Sioux Reservation is not a fatal blow to Dakota Access. The pipeline could be rerouted, and the Corps’s decision may be appealed.

An Iowa woman says she ended her two-week fast in protest of the Dakota Access Pipeline last night. Jessica Reznicek had a bowl of chicken soup after the Army Corps of Engineers denied an easement that puts completion of pipeline construction at an impasse.

The Army Corps has denied permission of pipeline construction for a section of the route in North Dakota. But it said the pipeline may be rerouted, so Reznicek is continuing her efforts to oppose Dakota Access, including a Wednesday sit-in at the utilities board.

With 100-year and 500-year floods happening in Iowa with increasing frequency, it’s important to understand how the state's ecology and infrastructure interact with rising water.

A group consisting of mayors and prominent business leaders is calling for an increase in the state sales tax. The extra money would go into a fund to support water quality and recreation projects. 

The Iowa Water and Land Legacy Coalition is asking the Legislature to up the state sales tax by three-eighths of a cent.

The extra cash would go into the Natural Resources and Outdoor Recreation Trust Fund.

Iowa voters overwhelmingly approved creation of the fund in 2010.

But the mayor of Storm Lake Jon Kruse says no state money has ever gone into it.

The sixth annual Iowa Climate Statement is aimed directly at farmers.

It follows the lead of U.S. Agriculture Secretary Tom Vilsack by calling for climate-smart agriculture.

The statement is signed by 187 scientists representing 39 colleges and universities in the state.

It urges farmers to take up efforts aimed at replacing carbon in the soil.

The director of the environmental science and policy program at Drake University, David Courard-Hauri, says climate-smart agriculture does more than reduce greenhouse gas emissions.

Andrew Derocher traveled to Norway in 1996 to study what he thought would be a large, untouched population of polar bears. The country had flat-out banned the commercial hunting of bears as part of the Oslo Agreement 23 years earlier. Derocher, a professor at the University of Alberta and a polar bear biologist, assumed that was enough time for the bears' population and health to rebound. What he found surprised him.

People opposed to the Dakota Access Pipeline have turned more than 33,000 petition signatures over to the U-S Department of Justice office in Des Moines. 

They want the department to review all permits that allow pipeline construction.

“We call upon President Obama to ensure the Army Corps of Engineers rejects the remaining permits in North Dakota and Iowa,” said Ross Grooters, member of the group Iowa Citizens for Community Improvement.  “Furthermore, the construction should be halted not just the 20 miles either side of Lake Oahe, but along the pipeline’s entire path.”

When Critters Do "The Shuffle"?

The chill in the air and the traces of color on the trees are sure signs of fall, and so are the large number of raccoons and possums you see along the roadsides. Wild animals all over Iowa are doing the "fall shuffle," and among these animals are the more than three hundred species of birds that can be seen flying across the state.

“A lot of the northern species are down in our area, or have already moved through," says Iowa State University Wildlife Biologist Jim Pease.

They all have similar reasons for heading south towards sunnier skies.

As fall hunting seasons approach, sportsmen and women will be able spread out more due to a USDA grant that incentivizes Iowa landowners to put private property into conservation. The Iowa Habitat and Access Program, or IHAP, pays people to improve natural habitat on their properties. In exchange, they allow the public the hunt on their lands.

In the early 1900s, one of the most populous birds in the world, passenger pigeons, were hunted to extinction in the wild. The very last passenger pigeon, Martha, died in captivity in 1914.   A few years later, the United States enacted the Migratory Bird Treaty Act, a treaty that has paved the way for conservation efforts that have saved countless endangered bird species.

Sandra Steingraber is proud of her PhD in biology, her position as Scholar in Residence at Ithaca College and her two arrests. Not necessarily in that order.

While Steingraber, an author, biologist, and activist, has studied science in a lab for decades, she knew she had to do more to effect the change she wanted to see in the environment. So she got herself arrested. Twice.

Governor Branstad says the Iowa Highway Patrol will be available to help local law enforcement police a planned protest against the controversial Bakken Crude Oil Pipeline.  

Critics threaten to engage in civil disobedience Wednesday to stop construction at a rural Boone County location.  

At his weekly news conference Branstad, says the Iowa Highway Patrol protects the safety and well-being of Iowans.

“Whether it is at the State Fair or on the highways or wherever it might be,” Branstad says.

There’s been a lot of talk in Iowa about water quality. From failed attempts by the legislature and the governor to come up with new funding, to the state’s largest water utility suing three rural boards of supervisors in northwest Iowa. That area of the state is part of a region called the “prairie pothole”. It stretches from Canada, down through the Dakotas, northern Montana and western Minnesota as well.

In North Dakota, much of this habitat is still intact and conservationists are concerned about the health implications of a landscape looking more like Iowa.

Putting the 'Wild' Back in Wildlife

Aug 9, 2016

In the early 19th century wild cougars, wolves, and bears once roamed the vast Iowa prairies, but today they're nowhere to be found. Where did they go, and where are they now?

During this hour of Talk of Iowa host Charity Nebbe talks with Emeritus Associate Professor of Natural Resource Ecology and Management at Iowa State University, Jim Pease, about the history of Iowa's native wildlife and some of its oldest predators.

Invasive plant species are becoming pervasive in Iowa’s woodlands.  State Forester Paul Tauke says a recent survey found invasives present in 95-percent of forest inventory plots studied.  He calls it a “shocking” finding.

“When you have exotic invasive species, they expand into an area and they tend to crowd out the native species, and decrease your diversity in the system," says Tauke

Many of us turn to nature for peace, recreation, and inspiration, and research is starting to support how interaction with the natural world can improve health and decrease stress.

Dr. Suzanne Bartlett is an Integrative Medicine Specialist at Mercy Medical Center in Cedar Rapids. When she started practicing medicine, she worked as an obstetrician. Today, she’s incorporating what she calls nature therapy into her new integrative medicine practice.

The Elusive American Badger

The honey badger may be an internet sensation, but Iowa is home to an equally tenacious species of badger. 

On this edition of Talk of Iowa, Charity Nebbe talks with wildlife biologist Jim Pease about the American Badger. 

Although badgers are rarely seen in Iowa, they do live here. Due to their independent nature it is hard to know exactly how many badgers are in state, but quite a bit is known about their lives in the Midwest.

When Luther College students Laura Proescholdt and Amy Thor first watched An Inconvenient Truth, Al Gore's documentary about climate change, they realized that their generation would face major environmental issues. And they wanted to do something about it, but what? 

“A lot of classes are all about the gloom and doom, but not many focus on solutions,” explains Thor.

A young black bear was struck by a glass-delivery truck and killed on Friday evening in far northeast Iowa.

The incident occurred on Highway 76, near the Yellow River Forest in Allamakee County.

"It's a heavily-wooded area," says Kevin Baskins of the Iowa DOT. "You obviously have the Mississippi River bordering it on the east side, and so there's a lot of pretty decent habitat for bears if they do wander into that neck of the woods."

A group of canoes and kayaks will travel down the Des Moines River on Saturday in protest of the Bakken Pipeline. 

Organizer Angie Carter expects at least 40 people to show up for the flotilla.

She describes the aquatic protest as a family-friendly way to encourage the Army Corps of Engineers to deny the pipeline permission to begin construction and issue an environmental impact statement.

'Finding Dory,’ the sequel to the very popular ‘Finding Nemo,’ hits theaters this weekend. Lots of fans of the first movie are excited. For some scientists, it’s a different story entirely.

Dory is a pacific blue tang fish, and just like sales of clownfish skyrocketed after the first movie, pet stores are anticipating demand for the pacific blue tang. That demand, however, could have serious consequences for a fish that can’t be breed in captivity.

It is easy to dismiss crows as a loud annoying neighbor, but they are deceptively smart. 

On this episode of Talk of Iowa  host Charity Nebbe talks to about Wildlife Biologist Jim Pease about Crows and other birds in the Corvid family. 

Besides crows, the Corvid family includes blue jays, ravens, and magpies. Corvids are a common birds, they are on every continent except Antarctica.

As summer approaches many people are out in their lawn, mowing, watering and pulling weeds. 

On this episode of Talk of Iowa host Charity Nebbe talks with  Iowa State University Extension turfgrass specialist Adam Thoms about lawn care. 

When it comes to mowing, Thomas recommends keeping your grass around three and three and a half inches tall, and not removing more than a third of the leaf tissue. This means mowing the lawn regularly.

The "Big Marsh" was a source of bounty for wildlife, native people and settlers.  When it was drained it offered up fertile soil, but what was lost?  This hour, we talk to Cheri Register, author of the new book, "The Big Marsh; the Story of a Lost Landscape" (Minnesota Historical Society Press).

Iowa gets an early taste of summer toward the end of this week, with temperatures expected to climb into the mid-90’s.  Health officials, animal welfare advocates, and the National Weather Service are issuing warnings in advance of the hot temperatures.

The Iowa Department of Public Health says about 500 Iowans are hospitalized each year with heat-related illnesses.

The Iowa Department of Natural Resources is expecting another summer boating season full of toxic, blue green algae blooms. There were a record number of beach closures in 2015 in Iowa, and the DNR is expecting this year to be the same or worse. 

The blooms release microcystin, which is a toxin released by cyanobacteria. The toxin can kill pets and cause rashes and flu like symptoms in humans.

As the weather heats up this week, Mary Skopec, beach monitoring coordinator for the Iowa DNR, says that we’ll likely start to see algal blooms that lead to beach closures.
