SECRETARY OF DEFENSE HAGEL ISSUES MESSAGE REGARDING INDEPENDENCE DAY

Secretary of Defense Chuck Hagel

FROM:  U.S. DEPARTMENT OF DEFENSE 
Hagel Issues Independence Day Message
American Forces Press Service

WASHINGTON, July 3, 2013 - In his Independence Day message issued today, Defense Secretary Chuck Hagel thanked U.S. troops and their families for their service to the nation.

Here is the text of the secretary's message:

On this Independence Day, I want to express my appreciation to the men and women and their families who serve our country across the nation and around the world. Thank you for everything you do to help keep our nation safe.

It's been 237 years since a small band of patriots signed the Declaration of Independence, in which they pledged their lives and their sacred honor to defend our unalienable rights to life, liberty, and the pursuit of happiness. Since then, generations of Americans have made that same pledge, boldly standing up in the face of tyranny, oppression, and persecution.

That legacy lives on today. This week marked the 40th anniversary of the all-volunteer force, a symbol of how our brave men and women in uniform continue to protect the freedoms declared by our founding fathers more than two centuries ago. Their devotion to duty is just as strong, as is their willingness to risk their lives for each other and our country. And their dedication is a reminder that the preservation of America's liberties does not come without cost.

Those who serve in our armed forces, and their families, have given much in the name of defending the ideals and free institutions we often take for granted. Today, as we celebrate our nation's birth, let us honor their dutiful service and strive to be worthy of their tremendous sacrifices.

God bless you, our great nation, and all who serve to protect it. Happy Fourth of July!

EPA ISSUES WARNING OF FIRE AND EXPLOSION RISKS WHEN USING REFRIGERANT SUBSTITUTES

FROM:  ENVIRONMENTAL PROTECTION AGENCY 
EPA Warns Against Use of Refrigerant Substitutes That Pose Fire and Explosion Risk

WASHINGTON – The U.S. Environmental Protection Agency (EPA) is warning homeowners, propane manufacturers and sellers, home improvement contractors and air conditioning technicians of potential safety hazards related to the use of propane or other unapproved refrigerants in home air conditioning systems.

EPA is currently investigating instances where propane has been marketed and used as a substitute for HCFC-22 (R-22), a refrigerant that is widely used in home air conditioning systems.

Home air conditioning systems are not designed to handle propane or other similar flammable refrigerants. The use of these substances poses a potential fire or explosion hazard for homeowners and service technicians.  

EPA is aware of incidents that have occurred both overseas and in the U.S. where individuals have been injured as a result of the use of propane and other unapproved refrigerants in air conditioning systems. We are investigating and will take enforcement actions where appropriate. Other names for these unapproved refrigerants include R-290, 22a, 22-A, R-22a, HC-22a, and CARE 40.

At this time, EPA has not approved the use of propane refrigerant or other hydrocarbon refrigerants in any type of air conditioner. Homeowners and technicians are strongly recommended to limit use of propane or other hydrocarbons to only those appliances specifically designed for these substances and that are properly marked to alert technicians that the equipment contains a flammable substance. EPA has approved the use of propane as a substitute refrigerant for R-22 in industrial process refrigeration systems and in new, stand-alone retail food refrigerators and freezers that are specifically designed to use flammable hydrocarbon refrigerants.

R-22 is being phased out of production and importation under the Montreal Protocol, an environmental treaty ratified by every country in the world designed to reduce and eventually eliminate the use of ozone depleting substances. EPA’s Significant New Alternatives Policy (SNAP) Program has already listed numerous refrigerants with improved environmental, health and safety profiles and continues to evaluate other refrigerants that can be used to replace R-22 and other ozone-depleting substances.

PRESIDENT OBAMA SIGNS EXECUTIVE ORDER TO HELP COMBAT WILDLIFE TRAFFICKING

FROM: THE WHITE HOUSE

FACT SHEET: U.S. Efforts to Combat Wildlife Trafficking

July 01, 2013

Wildlife trafficking is a multi-billion dollar illicit business that is decimating Africa’s iconic animal populations. Many species -- most notably elephants and rhinoceroses -- now face the risk of significant decline or even extinction. Like other forms of illicit trade, wildlife trafficking undermines security across nations. Well-armed, well-equipped, and well-organized networks of poachers, criminals, and corrupt officials exploit porous borders and weak institutions to profit from trading in illegally taken wildlife.


The United States is committed to combating wildlife trafficking, related corruption, and money laundering. With our international partners, we are working to reduce demand, strengthen enforcement, and building capacity to address these challenges bilaterally, regionally, and multilaterally.



A New Executive Order to Better Coordinate the U.S. Response

Today the President will sign an Executive Order (E.O.) to enhance coordination of U.S. Government efforts to combat wildlife trafficking and assist foreign governments in building the capacity needed to combat wildlife trafficking and related organized crime.

The E.O. establishes a Presidential Task Force on Wildlife Trafficking charged with developing a National Strategy for Combating Wildlife Trafficking. It also establishes an Advisory Council on Wildlife Trafficking comprised of eight individuals with relevant expertise from outside the Government to make recommendations to the Task Force.



New Assistance to Support Regional Partners

As the President will announce today in Tanzania, the U.S. Department of State will provide an additional $10 million in regional and bilateral training and technical assistance in Africa to combat wildlife trafficking. This will include approximately $3 million in bilateral assistance to South Africa, $3 million in bilateral assistance to Kenya, and $4 million in regional assistance throughout sub-Saharan Africa.

This training and technical assistance aims to:

1) Strengthen policies and legislative frameworks;

2) Enhance investigative and law enforcement functions;

3) Support regional cooperation among enforcement agencies; and,

4) Develop capacities to prosecute and adjudicate crimes related to wildlife trafficking.

In addition, USAID will launch a wildlife technology challenge, which will promote the use of innovative technologies like mobile phone applications and wildlife DNA analysis techniques to assist in combating wildlife trafficking.

The State Department, USAID, and the Department of Interior U.S. Fish & Wildlife Service (USFWS) will also assign a USFWS official to our Embassy in Dar es Salaam to support the Government of Tanzania's efforts to develop an overarching wildlife security strategy.



New U.S. Enforcement and Regulatory Efforts to Combat Wildlife Trafficking

The Transnational Organized Crime Rewards Program, which was signed into law on January 2013, enables the Secretary of State to offer rewards up for information leading to the arrest, conviction, or identification of significant members of transnational criminal organizations who operate primarily outside the United States.

The law also allows for rewards for information that dismantles such organizations or leads to the disruption of their financial mechanisms. The United States intends to leverage this new authority, as appropriate, to combat the most significant perpetrators of wildlife trafficking.

In addition, the Department of Interior will enhance regulations that directly affect illegal wildlife trafficking of elephants and rhinoceroses. These regulations pertain to U.S. federal laws including the Endangered Species Act, the African Elephant Conservation Act, and the Rhinoceros and Tiger Conservation Act.



Successes to Date and Building on On-going Activities

These new commitments build on on-going efforts within the U.S. Government, and with foreign governments, international organizations, nongovernmental organizations, and the private sector to reduce demand and strengthen enforcement and institutional capabilities. Representative examples include:


Capacity Building from Asia to Africa

USAID supports over $12 million per year in counter-wildlife trafficking activities, including support for anti-poaching activities in Africa and Asia, capacity building, and demand reduction campaigns in Asia.
The State Department and Department of the Interior / USFWS support the International Law Enforcement Academy in Gaborone, Botswana, which has trained 350 law enforcement officers in wildlife crime investigations since 2002.
To specifically address transcontinental trafficking, USAID is funding a three-year program with the International Union for the Conservation of Nature and the wildlife trade monitoring network TRAFFIC to improve understanding of current trends in wildlife trafficking and identify priority wildlife trafficking issues on behalf of the broader law enforcement and security communities.
The State Department is providing more than $2 million to support investigation, interdiction, and prosecution efforts in East Asia and the Pacific, including park ranger training and special investigative training for wildlife managers at the U.S. International Law Enforcement Academy in Bangkok.
The USFWS is providing an additional $2 million annually to support the Wildlife Without Borders capacity building program, which aids government agencies and non-governmental partners in enhancing wildlife law enforcement training, promoting best practices for community stewardship of wildlife resources, and addressing other critical conservation needs.
The Department of Justice and the USFWS jointly investigate and prosecute wildlife trafficking cases, working alongside international partners, to provide training and state-of-the-art forensic support for investigating and prosecuting wildlife crimes.

Conservation and Demand Reduction

The USFWS provides $10 million annually to enhance and support wildlife conservation throughout Africa and Asia. The funds support essential wildlife protection activities in 25 African countries, including improving capacity to carry out investigations and prosecutions of wildlife crime; developing effective park law enforcement and management to deter illegal hunting; improving management of key wildlife species and protected areas; and developing community management schemes.
USAID invests $200 million a year in biodiversity conservation, $70 million of which is in Africa. These investments provide support for community-based approaches to natural resources management in Africa, including community-scouting and ranger programs.
In consumer nations in Asia, USFWS supports government partners in awareness and demand reduction campaigns, which include public outreach to discourage consumption, noting the cost to wildlife of purchased exotic items, and highlighting criminal consequences of consuming illegally trafficked or purchased wildlife products.

Building a Coalition of Partnerships

The United States is working with the International Consortium to Combat Wildlife Crime and other interested partners to support the creation of a global network of regional and national Wildlife Enforcement Networks to improve communication and strengthen response actions across enforcement agencies globally. USAID has invested $17 million since 2005 to specifically support improving these regional networks of wildlife enforcement officials, as well as increasing public awareness, reducing demand for wildlife products, and building political will. The United States is also supporting the creation of new networks in central Africa and the Horn of Africa, among others in Asia and South America.
Additionally, the United States encourages participation by governments, civil society, and the private sector in existing partnerships that combat wildlife crime, such as the Coalition Against Wildlife Trafficking (CAWT).

Raising the Issue in International Fora

The United States successfully co-sponsored a resolution at the 2013 UN Commission on Crime Prevention and Criminal Justice encouraging UN Member States to classify wildlife trafficking as a "serious" crime as defined in the UN Convention against Transnational Organized Crime. This will facilitate further international cooperation among states that have ratified or acceded to the treaty, and will lead to increased penalties for traffickers.
Through U.S. advocacy, the 2012 APEC Leaders Declaration included commitments to address both the supply and demand for endangered and protected wildlife, including through capacity building and increased enforcement.

THE 4OTH ANNIVERSARY OF THE ALL-VOLUNTEER FORCE

FROM: U.S. DEFENSE DEPARTMENT

Top Service Members Mark All-volunteer Force's Anniversary

American Forces Press Service

WASHINGTON, July 2, 2013 - In a letter issued yesterday to the men and women of the armed forces, the nation's top two military officers and senior enlisted member marked the 40th anniversary of the all-volunteer force.


The letter -- signed by Army Gen. Martin E. Dempsey, chairman of the Joint Chiefs of Staff; Navy Adm. James A. Winnefeld Jr., vice chairman of the Joint Chiefs; and Marine Corps Sgt. Maj. Bryan B. Battaglia, senior enlisted advisor to the chairman -- reads as follows:

Since the Nation's founding, our sons and daughters have volunteered to leave the everyday comforts of their homes, their neighborhoods, and their families to join and serve a cause greater than themselves. They have joined a profession bound by honor, sacrifice, bravery, and -- in many cases -- danger. They serve a greater purpose -- protecting and defending the Constitution of the United States.

On 1 July 1973, the United States instituted the All-Volunteer Force. Those who choose to wear the cloth of our Nation do so with a great sense of pride and allegiance. To volunteer speaks volumes to the character, patriotism, and commitment of America's most precious resource -- our men and women who serve.

As we commemorate the 40th Anniversary of the All-Volunteer Force, we would like to pass our heartfelt appreciation to all those who have served and are serving in the United States Armed Forces. You are America's strength -- you honor our past, and you preserve our future.

Well done, Warriors -- thank you for your service!

DOD at Work on New Cyber Strategy, Senior Military Advisor Says

By Cheryl Pellerin
American Forces Press Service

WASHINGTON, July 1, 2013 - The Defense Department released its first strategy for operating in cyberspace two years ago this month, and officials are at work on the next version, the senior military advisor for cyber to the undersecretary of defense for policy said in Baltimore last week.

Army Maj. Gen. John A. Davis spoke to a lunch audience at the Armed Forces Communications and Electronics Association International Cyber Symposium, noting that two years might equal 20 in the domain that accommodates distanceless travel.

"Senior leaders in the department and beyond the department understand that cyber is a problem [and] cyber is important. They've made cyber a priority, and there is a sense of urgency," the general said.

The strategy's five initiatives were to treat cyberspace as an operational domain, use new defense operating concepts to protect Defense Department networks, partner with other federal agencies and the private sector for a whole-of-government approach, partner with international allies for a global approach, and leverage the nation's ingenuity through an exceptional cyber workforce and technological innovation.

The department's method for implementing the strategy is called the cyber initiative group, the general said. "It's a process that includes engagement at all levels, from the action-officer level all the way to senior defense leadership," he explained.

A great deal of work remains, he added, "but we have made some really good progress in a number of areas under each of these strategy components." The process has been difficult and complex, he added, which reflects the complex interrelationships involved in the cyberspace arena.

Over the past two years, Davis said, the department has made progress in several areas. For example, he told the audience, DOD has:

-- Established service cyber components under U.S. Cyber Command;

-- Established joint cyber centers at each combatant command;

-- Implemented a military-orders process to handle cyber action as it is handled in other operational domains in a process supported by an emergency conferencing procedure that links key organizations and leaders from across DOD and government to quickly assess major cyber threats and make decisions;

-- Established an interim command-and-control framework for cyberspace operations across joint service and defense agency organizations;

-- Developed a force structure model for cyber force organizations;

-- Established a plan and developed orders to transition to a new network architecture called the Joint Information Environment, or JIE, that will make DOD networks more effective, defendable and efficient; and

-- Conducted two years of Cyber Flag exercises at Nellis Air Force Base in Nevada that were joint, full-spectrum cyberspace operations exercises using live opposition forces and a virtual environment that mirrored current cyber threats.

DOD's mission is to defend the nation in all domains, but in cyberspace, the department shares its role with other members of the federal cybersecurity team, including the Justice Department and its FBI, the lead for investigation and law enforcement, the general said.

Other team members are the Department of Homeland Security -- the lead for protecting critical infrastructure and government systems outside the military -- and the intelligence community, which is responsible for threat intelligence and attribution, he added, noting that there are even roles and responsibilities for public-private and international partners.

DOD has begun to refine its role in defending the nation in cyberspace, Davis said.

"We have three main cyber missions, and three kinds of cyber forces will operate around the clock to conduct those missions," the general explained.

National mission forces will be prepared to counter adversary cyberattacks, he said. A second, larger set of combat mission forces will be prepared to support combatant commanders as they execute military missions, integrating cyber capabilities and effects into their military contingency plans and operations alongside traditional capabilities and effects, he added.

Still other cyber protection forces -- the largest set, Davis said, will operate and defend the networks that support military operations worldwide.

"We will deter, disrupt and deny adversary cyberspace operations that threaten vital U.S. interests when approved by the president and directed by the secretary of defense," he said. "If a crippling cyberattack is launched against our nation, the Department of Defense must be ready for an order from the commander in chief to act."

STATEMENT FROM EDUCATION SECRETARY DUNCAN ON TITLE VI ANNIVERSARY

FROM: U.S. DEPARTMENT OF EDUCATION

Statement by Secretary Arne Duncan on the Anniversary of Title VI

July 2, 2013

Today, U.S. Secretary of Education Arne Duncan released the following statement regarding the anniversary of Title VI of the Civil Rights Act of 1964:


"The 49th anniversary of the enactment of the Civil Rights Act of 1964 is an opportunity to reflect on the importance of education in America's progress toward racial equality.

"Title VI has prohibited discrimination on the basis of race, color, or national origin in any program or activity - including all elementary and secondary schools and colleges and universities, public or private - receiving Federal financial assistance.

"The Department of Education's Office for Civil Rights has used Title VI to promote equal access to college- and career-preparatory courses and programs and to combat school segregation, discriminatory discipline, harassment, and other barriers to equal education for students of different racial, ethnic and linguistic backgrounds.

"We still have a long way to go to achieve racial equity. Last week, in the Fisher case, the Supreme Court preserved the well-established legal principle that colleges and universities have a compelling interest in achieving the educational benefits that flow from a racially and ethnically diverse student body, and can pursue that interest in their admissions programs. Lack of access to college- and career preparatory school programs persist, and racial disparities in discipline deny equal opportunity to too many of our students of color. Many of our nation's schools are still racially isolated, and racial gaps continue to exist in important measurements of learning.

"Today, we at the Department of Education recommit ourselves to enforcing Title VI to help end illegal discrimination in our country's schools and promote equitable opportunities for all students. We salute the states, districts, communities and advocates across America that have worked tirelessly to ensure that racial discrimination is eliminated as a barrier to student learning and success."

SENATOR LEVIN'S STATEMENT ON GLEEPA

FROM: U.S. SENATOR LEVIN'S WEBSITE
Senate Floor Statement on the Introduction of the Great Lakes Ecological and Economic Protection Act of 2013

Wednesday, June 26, 2013

Mr. LEVIN. Mr. President, the Great Lakes are a magnificent resource and unique in the world. These water bodies, formed during the last ten thousand years, are the largest source of surface freshwater on the planet. The lakes shaped how people settled and secured resources for their survival. Native Americans, French explorers, early European settlers, immigrants flocking to new industrial cities, along with the current populations of today all rely on the lakes for their survival – providing food and drinking water, transportation, power, recreation, and magnificent beauty.


However, the vast resources the Great Lakes provide must not be taken for granted. We must do all we can to protect these waters and clean up the areas that have been harmed by toxic contaminants, polluted runoff, untreated wastewater, and destructive invasive species. That is why as co-chairs of the Senate Great Lakes Task Force, Senator Kirk and I, along with several of our colleagues, are introducing today the Great Lakes Ecological and Economic Protection Act of 2013, or GLEEPA.

This bill builds upon the work of a multitude of stakeholders -- environmental organizations; business associations; tribal governments; community leaders; and federal, state and local officials – who worked together to craft the Great Lakes Regional Collaboration Strategy, a 2005 plan to guide restoration and protection for the Great Lakes. The legislation we are introducing today would formally authorize the Great Lakes Restoration Initiative (GLRI), an inter-agency program designed to implement the plan articulated in the Collaboration Strategy.

The GLRI is an action-oriented, results-driven initiative targeting the most significant problems in the Great Lakes, including aquatic invasive species, toxics and contaminated sediment, nonpoint source pollution, and habitat and wildlife protection and restoration. While broadly authorized under the Clean Water Act, the GLRI should be specifically authorized in law to clarify its purpose and objectives and to demonstrate support from Congress. Since the GLRI was launched in fiscal year 2010 with $475 million in funding, real progress has been made to restore the health of the Great Lakes: More than a million cubic yards of contaminated sediments have been cleaned up. More than 20,000 acres of wetland, coastal, upland and island habitat have been restored or enhanced. New technologies are being developed to combat the sea lamprey. Asian carp have been prevented from establishing a sustaining population in the Great Lakes. Hundreds of river miles have been restored to enable free fish passage from the Great Lakes to their spawning grounds. Reduction of nutrient loading from agriculture runoff has lessened occurrences of harmful algal blooms.

In addition to authorization of the GLRI, this legislation would reauthorize two existing programs: (1) the Great Lakes Legacy program, which supports the removal of contaminated sediments at more than thirty Areas of Concern (AOCs) across the Great Lakes; and (2) the Great Lakes National Program Office, which handles Great Lakes matters for the EPA.

The health and vitality of the Great Lakes not only provide immense public health and environmental benefits, but they are also critical to the economic health of the region. For example, in Muskegon Lake, which is directly connected to Lake Michigan, cleanup of 430,000 cubic yards of sediment contaminated with mercury and polycyclic aromatic hydrocarbons, or PAHs, also provided jobs to barge and dredge operators, truck drivers, biologists, chemists, toxicologists, and general laborers. The cleanup will help lift fish consumption advisories and restore fish habitat, which is vital to this area that is a popular fishing and boating destination.

Reports find a two to three dollar return for every dollar invested in cleanup and restoration activity. And preventing future damage to the lakes – from aquatic invasive species for example – could easily save the public hundreds of millions of dollars in future expenditures. With a $7 billion fishery, $16 billion in annual expenditures related to recreational boating, and about 37 million hunters, anglers and bird watchers enjoying the Great Lakes each year, we cannot afford to not protect and restore this precious resource.

The legislation we are introducing today includes important safeguards to ensure that tax dollars are wisely spent on activities that actually achieve results. Projects are directed to be selected so that they achieve strategic and measurable outcomes and which can be promptly implemented through leveraging additional non-federal resources. The bill would also authorize an inter-agency task force to coordinate federal resources in a way that most efficiently uses taxpayer funds, focusing on measurable outcomes such as cleaner water, improved public health, and sustainable fisheries in the Great Lakes.

Finally, state and local officials, tribal governments, business organizations, environmental organizations, and other stakeholders need an avenue to communicate on matters pertaining to Great Lakes restoration. Recently, the EPA created a board that advises the EPA and other federal agencies on Great Lakes cleanup and protection activities. This bill would make the advisory board permanent to ensure that the many voices across the Great Lakes region can have a direct conduit to the federal government.

Mr. President, the Great Lakes are home to more than 3,500 species of plants and animals and support 1.5 million direct jobs, $62 billion in wages and a $7 billion fishery. This legislation is needed to address the threat of invasive species such as Asian carp, polluted runoff that can harm aquatic and public health, toxic sediments, and harmful algal blooms that kill fish, foul coastlines, and threaten public health. The legislation will also help the United States implement its commitment to the bi-national 2012 Great Lakes Water Quality Agreement. We hope the Senate Committee on Environment and Public Works will promptly act on this important legislation, as it did in 2010 when it approved similar legislation.

WATERSHEDS AFFECTED BY BARK BEETLES

FROM: NATIONAL SCIENCE FOUNDATION
Ghosts of Forests Past: Bark Beetles Kill Lodgepole Pines, Affecting Entire Watersheds

In mountains across the Western United States, scientists are racing against time--against a tiny beetle--to save the last lodgepole pines.


Forests are bleeding out from the effects of the beetles, their conifers' needles turning crimson before the trees die.

Now, researchers are also hurrying to preserve the region's water quality, affected by the deaths of the pines.

"When these trees die," says hydrologist Reed Maxwell of the Colorado School of Mines, "the loss of the forest canopy affects hydrology and the cycling of essential nutrients."

Maxwell and other scientists recently published results of their study in the journal Biogeochemistry.

Co-authors, in addition to Maxwell, are Kristin Mikkelson, Lindsay Bearup, John McCray and Jonathan Sharp of the Colorado School of Mines, and John Stednick of Colorado State University. Mikkelson is the paper's first author.


Bark beetle numbers: heating up
"The mountain pine beetle outbreak in Western states has reached epidemic proportions," says Maxwell.

Bark beetles, as they're known, are native to the United States. They're so-named as the beetles reproduce in the inner bark of trees. Some species, such as the mountain pine beetle, attack and kill live trees. Others live in dead, weakened or dying hosts.

Massive outbreaks of mountain pine beetles in western North America since the mid-2000s have felled millions of acres of forests from New Mexico to British Columbia, threatening increases in mudslides and wildfires.

Climate change could be to blame. The beetles' numbers were once kept in check by cold winter temperatures and trees that had plenty of water to use as a defense.

But winters have become warmer, and droughts have left trees water-stressed and less able to withstand an onslaught of winged invaders.

"A small change in temperature leads to a large change in the number of beetles--and now to a large change in water quality," says Tom Torgersen, director of the National Science Foundation's (NSF) Water, Sustainability and Climate (WSC) Program, which funded the research.

WSC is part of NSF's Science, Engineering and Education portfolio of investments.

"Bark beetles have killed 95 percent of mature lodgepole pines," says Maxwell.

Death of a lodgepole pine

But the trees don't die immediately.

When beetles invade, a blue fungus spreads inside a tree's trunk, choking off transpiration and killing the tree in about two years.

The trees turn blood-red, then the ashen gray of death, dropping their needles to the forest floor.

"Some of the most important effects of bark beetles may be changes in the hydrologic cycle," says Maxwell, "via snow accumulation under trees and water transpiration from trees and other plants."

Biogeochemical changes may be even more important, he says, with carbon and nitrogen cycles interrupted.

"We're studying these hydrologic and geochemical processes through a combination of field work, lab research and computer modeling," says Maxwell.


Whither the beetles, so the trees, forests...and waters
Changes in tree canopies affect snowpack development and snowmelt.

For example, a lack of needles on branches lets more snow fall through the canopy--snow that would otherwise be caught on branches. A tree without needles also has less shade beneath it.

The result is a shallower snowpack, earlier snowmelt and less water in spring.

"The real question," Maxwell says, "is how these processes translate from individual trees to hillslopes to large watersheds."

Dead trees don't transpire water. Once a forest has died, this important flow of moisture from the ground to the atmosphere ceases.

That can mean a loss of as much as 60 percent of the water budget, although increases in ground evaporation or transpiration from understory shrubs and bushes may compensate for some of the lack.

"Combined with what's happening to snowpack depth," says Maxwell, "it becomes a complicated relationship that can change the timing and magnitude of spring runoff from snowmelt--and an entire year's water resources."

Tree mortality also appears to affect forest carbon and nitrogen cycles through increases in dissolved organic carbon.

"We've seen changes in drinking water quality in beetle-affected watersheds that are almost certainly related to high dissolved organic carbon levels," says Maxwell.

As Maxwell, Mikkelson, Bearup and colleagues discovered, there's a lag time between beetle infestation and water quality declines, "so tree and forest water transport processes are very likely involved," says Maxwell.


All watersheds great and small
The observations prompted the researchers to study processes at the individual tree and hillslope scale to better understand what's happening in watersheds large and small.

"Watersheds are complex, interrelated systems," says Maxwell, "which makes understanding them more challenging.

"We're developing complex, numerical models of bark beetle-infested watersheds that include our best understanding of how and where water flows. The models are allowing us to isolate individual processes by turning them on and off in 'what-if' scenarios."

Along with on-the-ground observations, he says, "they're showing us more of the complex story of pine beetle effects on Western watersheds.

"We now know that healthy watersheds ultimately depend on healthy forests."

Western streams and rivers soon may be part of dead and dying forests, surrounded only by the ghosts of lodgepole pines past.

REMARKS BY PRESIDENT OBAMA AT DINNER IN DAR ES SALAAM, TANZANIA

FROM:  THE WHITE HOUSE

Remarks by President Obama in an Exchange of Dinner Toasts -- Dar es Salaam, Tanzania

State House
Dar es Salaam, Tanzania

8:58 PM EAT

PRESIDENT OBAMA: President Kikwete, Madam First Lady, distinguished guests -- on behalf of myself and Michelle, our delegation, our daughters -- we want to thank you for the incredible warmth and hospitality with which you've greeted us throughout the day. We could not be more grateful.

I am not the first American leader to visit this beautiful country. Other Presidents and prominent citizens have come before me. We just came from South Africa, where Robert Kennedy famously spoke of how every time we stand up for an ideal, we send out a "tiny ripple of hope." Less known is that after that trip to South Africa, Robert Kennedy also came here to Tanzania. It was a little different back then. Kennedy and his wife, Ethel, rode in the back of an open truck. The Secret Service has me and Michelle inside a fortified limousine. We call it "The Beast." (Laughter.) As Kennedy's truck made its way through the crowds, he picked up two boys and let them ride alongside them. The Secret Service doesn't let me do these things. (Laughter.) When Kennedy came, it was a public holiday here. I apologize to Tanzanians that you all had to work today. (Laughter.)

But while these times have changed, the good feelings stay the same. We've been deeply touched by the welcome and the warm wishes from the Tanzanian people along the streets as we came in here with you tonight. Dar es Salaam means "harbor of peace," and we thank you for sharing that sense of peace and brotherhood for which this country and its people have long been known.

Mr. President, you've shown wisdom and strength in seeking reforms so that more Tanzanians can enjoy progress, more opportunity. And like me, you're strengthened by a woman who is a leader in her own right. (Applause.) I am told that Mama Kikwete is fond of a traditional Tanzanian saying -- "My neighbor's child is my child." And that sentiment I think also captures the feeling, the partnership between -- our two countries must have. We live thousands of miles apart, but as fellow human beings, we share a sense of obligation to each other, especially to the youngest among us.

So you might say an American child is my child. We might say a Tanzanian child is my child. In this way, both of our nations will be looking after all of our children and we'll be living out the vision of President Nyerere. The core values that he proclaimed for Tanzania also describe what both our countries seek -- wisdom, unity, and peace -- Hekima, Umoja, na Amani. (Applause.)

So what I'd like to do is to propose a toast -- if I can get my water here -- to our gracious Tanzanian hosts, to our Tanzanian friends and to wisdom, unity and peace that we all seek in the world. Cheers.
