Saludos-Greetings-Aloha to one and all in the new year.

When I wrote last May about the unwelcomed arrival of the Puerto Rican coqui frogs to Hawaiian shores, little did I know that there was going to be such a heated debate in blogosphere. Personal feelings aside, the multiple responses received motivated me to actually find out what is the Agency’s role in addressing the growth of the coqui population throughout the 50th state. After making several calls and sending some emails, I was surprised to find that EPA’s role is limited.

In fact, the Agency was asked to step in the control efforts when the State of Hawaii needed an exemption to use an unregistered product to control the coquis. EPA is involved in this issue because products sold and used as pesticides must be evaluated and approved by the Agency under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) to ensure they can be used safety and without posing any unreasonable risks to people or the environment. In this case, Hawaii has requested an emergency exemption to use an unregistered product (calcium hydroxide or hydrated lime) as a pesticide in a quarantine program to control the invasive species, the Coqui. Hawaii is concerned that the frogs pose a serious threat to both agriculture and to the native Hawaiian forest ecosystems, including endangered species. I have been informed that the Agency is in the process of reviewing this request. Currently, there is a multiagency effort to stop the spread of the coqui in Hawaii led by the Hawaii Department of Agriculture.

While I confess that this dialogue in Greenversations has been eye-opening, I still yearn for the nocturnal coqui chants I experienced in my youth. Recently a friend asked why the coquís in Hawaii seem so much louder and active than the original coquis in their natural setting. In addition to the invasive nature of the coqui in Hawaii, I think we also can attribute the contrasts largely to the differences in population density and urban sprawl. In Hawaii, the population density is 188.6 inhabitants for square mile. In Puerto Rico, it’s 1,127 inhabitants for square mile! While there are numerous groups to save the coquí in Hawaii let’s not forget the plight of the coqui in Puerto Rico.

Saludos y aloha para todos en el nuevo año.

Cuando escribí en mayo pasado sobre la llegada poco acogida de los anfibios coquí puertorriqueños a las costas hawaianas, nunca pensé que se fuera a producir un debate tan intenso en la blogosfera. Dejando a un lado mis sentimientos personales, las múltiples respuestas recibidas me motivaron a investigar realmente cuál es el papel que desempeña la Agencia para abordar el crecimiento de la población coquí en el estado número 50. Después de varias llamadas y correos electrónicos, me sorprendí al ver que el rol de EPA es limitado.

De hecho, se le solicitó a la Agencia intervenir en los esfuerzos de control cuando el Estado de Hawai necesitaba una exención para utilizar un producto no registrado para el control de los coquí. EPA está participando en este asunto porque los productos que son vendidos y utilizados como pesticidas tienen que ser evaluados y aprobados por la Agencia bajo la Ley Federal de Insecticidas, Fungicidas y Rodenticidas (FIFRA, por sus siglas en inglés) para asegurar que se utilicen de manera segura sin presentar riesgos irrazonables al público ni al medio ambiente. En este caso, Hawai ha solicitado una exención de emergencia para utilizar el producto no registrado (hidróxido de calcio o cal hidratada) como un plaguicida en un programa de cuarentena para controlar la especie invasora, el coquí. Hawai está preocupada de que estos anfibios representan una seria amenaza tanto para la agricultura como para los ecosistemas forestes autóctonos al Hawai, incluyendo especies en peligro de extinción. Se me ha informado que la Agencia se encuentra en el proceso de revisar esta solicitud. En la actualidad, hay un esfuerzo multiagencial para frenar la propagación del coquí en Hawai dirigida por el Departamento de Agricultura estatal.

Tengo que confesar que mientras este diálogo en Greenversations (Conversaciones verdes) ha sido aleccionador, todavía añoro el cantar nocturno del coquí que viví en mi juventud. Recientemente un amigo me preguntó el por qué los coquí en Hawai parecen tener un canto mucho más fuerte que sus parientes originales en su medio natural boricua. Además de la naturaleza invasora del coquí en Hawai, creo que los contrastes se pueden atribuir también a las diferencias en la densidad poblacional entre ambos grupos isleños. En Hawai, la población demográfica es de 188.6 habitantes por milla cuadrada. ¡En Puerto Rico, hay 1,127 habitantes por milla cuadrada! Mientras hay numerosos grupos que quieren salvar el coquí en Hawai, no nos olvidemos de los problemas del coquí en Puerto Rico.

About the Author: Susan Lundquist works in EPA’s Ecosystem Services Research Program. She has been with the Agency for almost seven years.

Like so many consumers out there, I admit I spent time Thanksgiving Day combing through newspaper ads in preparation for the next day. It’s my usual thing, coffee early in the morning when it’s still dark, lending a certain mystic quality to an otherwise silly tradition of planning my shopping attack—solidifying my vision of goodies bought at bargain prices.

I indulged until I ran across an ad for a mini indoor garden for fresh herbs and lettuces grown under a sophisticated lighting system. Great idea, but suddenly I realized I already had an environmental bargain of my own, a raised-bed, outdoor winter garden.

I’m growing a winter garden using simple raised garden beds, a hoop house for each bed, and plastic covering. I’m eating seasonally with fresh cilantro, arugula, thyme, parsley, red and green leaf lettuces, chives, and mesclun.

Seeing the ad for the mini garden made me think about my job. I work in the Ecosystem Services Research Program at EPA. After all, my makeshift outdoor garden is a mini ecosystem in its own right. My indulgence in Black Friday ads made me ponder the significance of the Ecological Research Program recently changing its name to the Ecosystem Services Research Program (ESRP).

We changed the name so it would more accurately reflect how the goods and services we get from nature may be adversely affected or positively enhanced by management actions. On the tiny scale of my garden, an adverse action might be using pesticides that harm the bees and other pollinators that are the basis for my harvest.

The goal of the ESRP is to transform the way we account for the type, quality and magnitude of nature’s good and services, what we call “ecosystem services.” So even though my winter garden is on a small scale, it provides a great example of one of the fundamental ecosystem services: food production.

Isn’t it time we start thinking about ecosystem services on a larger scale and how we can begin to more accurately account for the cost of using these services? It’s certainly food for thought in early morning hours before Black Friday.

About the author: Aaron Ferster, a science writer in EPA’s Office of Research and Development, is a regular contributor to Science Wednesday.

Last Spring, a pair of barred owls took up residence in the upper reaches of a tree just past the edge of our yard. They announced their presence during dinner one warm evening, a series of deep hoots in a pattern birders describe as “who-cooks-for-you.”

We caught a brief glimpse of one as it leaned off its perch and in a long, silent swoop faded into the shadows of the woods behind our house, disappearing like a ghost.

The owls didn’t disappear for long. The girls soon discovered a trove of owl pellets beneath the roost. By picking the pellets apart we learned what the owls were eating. Sometimes there were crayfish claws or fish scales, but the owl’s main course must have always included small mammals. Every pellet contained the tiny white vertebra and jaw bones of mice.

Could owls and other wild neighbors be good for health by reducing the relative abundance of tick-infected mice? Last week I got to tag along with a team of Yale researchers surveying mammal diversity in the forests of Connecticut, part of an EPA-funded effort to explore just such questions.

Naturally, the team is taking a much more scientific approach than sifting through a handful of owl pellets. Instead, they set out small aluminum traps to humanely capture a representative sample of the local small mammal population.

Every critter caught was identified, ear-tagged (if not previously captured, a regular occurrence), and weighed. Before they were set free, each animal was thoroughly inspected and any black-legged ticks found were collected for further analysis. After the first day, we joined forces with another team conducting a similar survey of birds, part of an ongoing population study now sharing their efforts with the Yale team.

The few days I spent with the survey team is a small part of a larger, two-year study to better understand of the links between biological diversity, land use, and Lyme disease. I was happy to have the chance to escape the office for a few days in favor of the forest. It reminded me once again how fun it is to explore the woods and to learn more about our wild neighbors, some of which might prove to be important for our health.

Judging from previous blogs, there’s quite a bit of interest and concern towards the apparent lack of butterflies this summer. Yet we haven’t addressed something even potentially more worrisome—honeybees. The situation has been identified as the Colony Collapse Disorder (CCD). The disappearance of these pollinators could have serious repercussions on U.S. agriculture and ultimately the entire food supply. Experts still do not know the exact cause for the vanishing of the honeybees. Among the theories considered are: invasive parasitic mites, new and emerging diseases, pesticide poisoning, poor nutrition and I’ve even read some articles that attribute the situation to climate change.

Nonetheless, EPA, USDA, universities and the private sector have moved into action. The Agency is addressing the CCD through regulatory and voluntary programs. And it’s actively participating in the Colony Collapse Disorder Steering Committee and Working Group. One of the many collaborative efforts to address the issue has been a partnership between the Agency and the North American Pollinator Protection Campaign.

As I’ve been reading up more on this crisis, images of childhood–my grandfather with a hat and a veil tending to the bee colonies in his farm in Guayama, Puerto Rico come to mind. I also remember eating sticky, deliciously sweet, fresh honey. More recently, my daughter’s boyfriend, Scott, concerned over the CCD decided to take a beekeeping class by the Bowie Upper Marlboro Beekeepers Association (BUMBA) at Watkins Park Nature Center in Maryland. Both he and his brother started raising bees in their backyard in March. They started with one box and in June added a second one on top for them to expand. Scott hasn’t had any major problem and only one bee sting while working on the hive. The bees have made some honey, but he’s trying to save it for the winter. That will be the real test to his success so far.

While I haven’t taken the challenge to set up my own bee colony, I’ve been trying to use greenscaping techniques to minimize the use of pesticides in my garden. Overall, integrated pest management principles both at home and in agriculture, can go a long way to protect the ecosystem of these invaluable pollinators. We can’t live without them. So don’t just buzz by this blog, help to take action.

Va más alla de las aves y abejas

Juzgando por el interés de previos blogs, hay muchas personas preocupadas por la aparente falta de mariposas este verano. Sin embargo, todavía no hemos abordado un tema de mayor preocupación—las abejas de miel. La situación se ha identificado como el desorden del colapso de colonias (CCD, por sus siglas en inglés). La desaparición de estos polinadores podría causar serias repercusiones en la agricultura de Estados Unidos y en la totalidad del suministro de alimentos.

Los expertos aún no conocen la causa exacta de la desaparición de las abejas de miel. Algunas teorías son: pequeños ácaros parasíticos invasivos, nuevas enfermedades, el envenenamiento por pesticidas, la pobre nutrición y algunos artículos incluso atribuyen la situación al cambio climático.

Mientras tanto, EPA, el Departamento de Agricultura Federal, las universidades y el sector privado han entrado en acción. La Agencia está tratando el tema mediante programas de regulaciones y voluntarios. También está participando activamente en el Comité Timón y Grupo de Trabajo sobre el Desorden del Colapso de Colonias. Uno de los muchos esfuerzos colaborativos para abordar este asunto es el consorcio entre la Agencia y la Campana de Protección de Polinadores de Norte América.

Mientras voy leyendo más sobre la crisis, surgen las imágenes de mi infancia en Puerto Rico—mi abuelo con su sombrero especial cuidando de las abejas en su finca en Guayama, Puerto Rico. También me recuerdo comer la miel fresca, pegajosa y deliciosamente dulce…Recientemente, Scott, el novio de mi hija, preocupado por el colapso de colmenas decidió toma una clase para criar abejas que ofrece la Asociación de Apicultores de Upper Marlboro (BUMBA, por sus siglas en inglés) en el Centro de Naturaleza del Parque Watkins en Maryland. Tanto él como su hermano empezaron a cultivar las abejas en su patio en marzo. Comenzaron con una caja y en junio añadieron una más como una extensión para que las abejas pudieran expandir la colmena. Scott no ha tenido problemas en esta empresa y sólo una abeja lo ha picado. Las abejas han producido miel, pero él quiere conservarla para el invierno. Esa será la prueba real.

Mientras no ha tomado el reto de desarrollar mi propia colonia de abejas, estoy tratando de usar técnicas de jardinería verde para minimizar el uso de plaguicidas en mi jardín. Sobre todo, los principios para el manejo integrado de plagas tanto en el hogar como en la agricultura pueden contribuir enormemente a la protección del ecosistema de estos valiosos polinadores. No podemos vivir sin ellos. No ignoren este blog. Por favor, tomen acción.

In my nightly Web surfing, I came across an article on the “Top 25 Things Vanishing From America.” As expected, the loss of some “old technologies” like the VCR, dial-up internet access, phone landlines, analog TV, made the list. However, what struck me enough to write about it in today’s blog was the mention of the Chesapeake Bay Blue Crabs and honey bees.
Maryland has been my home for nearly 28 years. The blue crab, is practically a state icon. I must note that my family and I enjoy eating crabs in many ways. In this era of going “local” in our culinary habits, you would think that living in the Free State, eating crabs is the right thing to do. Yet this Internet article has made me reflect and question—should we keep crabs off the menu for a while?

Overfishing, water pollution and excessive nutrients are threatening the blue crab and aquatic wildlife that live in and around the Chesapeake Bay, the largest estuary in the United States. This important watershed spans six states—Maryland, Virginia, Delaware, Pennsylvania, West Virginia, New York and the nation’s capital, Washington, DC. EPA and its state partners work closely together to accelerate progress towards a healthy Bay. Through the Chesapeake Bay Program, EPA is trying to make a difference in restoring the blue crab habitat by working to improve water quality and submerged aquatic vegetation. In the meantime, the role of setting harvest regulations for the blue crab lies primarily on the states along the Bay.

Whether you’re concerned about the Chesapeake Bay or your local watershed, there are simple steps you can take in your home, school, community or the workplace to protect these precious aquatic resources. For example, conserve water! Don’t pour used motor oil down the drain! Used oil from a single oil change can ruin a million gallons of fresh water—A year’s supply for 50 people. Use greenscaping techniques in your garden. Bottom line—learn and get involved.

¿Maryland sin cangrejos?

En mis viajes por Internet, encontré un artículo sobre las “Principales 25 cosas que están desapareciendo de América”. Como era de esperarse, la pérdida de algunas “viejas tecnologías” como los VCR, las líneas telefónicas terrestres, la TV análoga figuraban en la lista. Sin embargo, lo que me chocó y motivó a escribir el blog de hoy fue la mención de los cangrejos azules de la Bahía de Chesapeake y las abejas de miel.

Maryland ha sido mi hogar durante casi 28 años. El cangrejo azul es casi un ícono estatal. Debo destacar que a mi familia a mí nos encanta comer cangrejos de diversas formas. En esta era de abogar por los hábitos culinarios locales, uno pensaría que viviendo en Maryland, el comer cangrejos sería aconsejable. Sin embargo, con este artículo del Internet, me he puesto a pensar–¿acaso debemos eliminar los cangrejos del menú por algún tiempo?

La pesca en exceso, la contaminación del agua, y los nutrientes excesivos están amenazando el cangrejo azul y la vida silvestre acuática en y alrededor de la Bahía Chesapeake, el estuario más grande en Estados Unidos. Esta importante cuenca fluvial abarca seis estados—Maryland, Virginia, Delaware, Pensilvania, Virginia Occidental, Nueva York y la capital federal, Washington, DC. EPA y sus socios estatales trabajan estrechamente para acelerar el progreso hacia una bahía saludable. Mediante el Programa de la Bahía de Chesapeake, EPA está tratando de hacer una diferencia en la restauración del hábitat del cangrejo azul al trabajar para mejorar la calidad del agua y la vegetación acuática sumergida. Entretanto, el rol de establecer las regulaciones para la cosecha del cangrejo azul recae primordialmente sobre los estados vecinos a la bahía.

Independientemente de su interés en la Bahía del Chesapeake o su cuenca fluvial local, hay pasos sencillos que puede tomar en su hogar, colegio, comunidad o lugar de trabajo para proteger estos preciados recursos acuáticos. Por ejemplo, ¡conserve agua—cada gota cuenta! ¡No eche el aceite de motor usado por la alcantarilla! El aceite usado de un simple cambio de aceite puede contaminar un millón de galones de agua fresca—el suministro de 50 personas para un año. Utilice técnicas de jardinería verde en su jardín. A fin de cuentas—aprenda y participe activamente en la protección ambiental.

About the author: As Jeffrey Levy of EPA’s blog team enjoyed a recent vacation, he sent along environmentally relevant thoughts and pictures.

We’ve been back home now for a few weeks. Hawaii was a pretty incredible way to spend our 15th anniversary. Aside from a sense of wonder, a couple of things struck me while I was there that have stayed with me.

First, it amazed me how little air conditioning is used in Hawaii. Between the trade winds and the magically low humidity (I mean, it’s a tropical island!), it was remarkably comfortable even in the upper 80s. And I get hot here in DC when it breaks 75. What’s funny is that when I’ve brought it up to friends who have also visited, they say they were also surprised.

The Honolulu airport was mostly open to the outside. Actually, some gates have air-conditioned spaces, but not the main terminal. I wonder how they decide where to put it? And then there’s the Kona airport, which really goes without AC:

You check in under a series of open-air pavilions. Once you’re though security, there is no concourse. Instead, each gate area has its own pavilion, and you walk across an open-air courtyard to get to your gate.

My first hint that’s how it would be came when making reservations, and every place mentioned ceiling fans but not AC. In fact, the only place with AC was our Waikiki hotel. I wonder if that’s a heat-island effect, or it’s just that there’s little airflow through a high-rise hotel room. Or maybe it’s that tourists expect AC, so hotels there include it.

Hawaiians seem in tune with their environment in a way that I envy. And in this case, they save a lot of energy by relying on their special climate to keep things comfortable. If only we could import it here. When we landed in DC at 10:00 pm, it was only 73 degrees but about 20 times stickier.

The other thing I wanted to mention is the coqui frog. You may remember Lina Younes asking people in Hawaii not to eradicate this Puerto Rican favorite. I’ll leave the debate about whether to eradicate them in the comments on that post.

But Lina commented on my first Hawaii post asking whether I’d heard the little songsters. Did I ever! North of Hilo, we heard a single frog, and I can understand Lina’s fond memories of “co-kee, co-kee” lulling her to sleep.

But south of Hilo in the forest, they were so loud we could hear them through the car windows (yes, we were hot, so we put on the AC). So for Lina, I recorded them: Hawaiian coqui (MP3 sound file, 20 seconds, 550 KB, transcript).

Now I understand why people commented on Lina’s post that the coquis had destroyed their peaceful evenings!

About the author: Dr. Robert Lackey is a senior scientist in EPA’s Office of Research and Development’s laboratory in Corvallis, Oregon. He has been involved professionally with West Coast salmon issues for 44 years and was awarded EPA’s highest award, the Gold Medal, for his salmon work.

One of my favorite fictional characters is detective extraordinaire Joe Friday. Joe demanded and provided “just the facts” as he sleuthed his way through the gossip and hearsay to winnow out the truth. Scientists responsible for informing the public and policy makers about ecological policy issues should attempt to do the same — just the facts — the straightforward, sometimes unpleasant realities.

A case in point: The 2008 collapse of salmon runs along the West Coast is being chronicled in major national newspapers, with headlines proclaiming “Disaster Strikes West Coast Fishermen,” “Worst Salmon Runs in History,” and “Agencies Baffled by Unexpected Salmon Collapse.”

Let’s apply Joe Friday’s “just the facts” approach to the wild salmon situation to see what society might expect in the future.

Fact 1: Wild salmon in California, Oregon, Washington, Idaho, and southern British Columbia are in serious trouble. Most runs in the Western U.S. are at less than 10% of their pre-1850 levels. Over two dozen are listed as threatened or endangered, with many more likely to follow unless something changes.

Fact 2: Meager salmon runs along the West Coast are nothing new. The decline in wild salmon numbers (PDF) started with the California gold rush in 1848; causes include water pollution, habitat loss, over-fishing, dams, irrigation projects, predation, and competition with hatchery-produced salmon and non-native fish species.

Fact 3: If society wishes to change the future for wild salmon, something must be done about the unrelenting growth in the human population level along the West Coast (California, Oregon, Washington, Idaho, and British Columbia). By 2100, there could be 200 - 250 million people in the region: a quadrupling by the end of this century — barely 90 years from now.

Fact 4: If the human population levels increase as expected, options for restoring salmon runs to significant, sustainable levels are greatly limited. Consider the demand for houses, schools, stadiums (PDF), expressways, automobiles, malls, air conditioning, drinking water, consumer goods, golf courses, and sewer treatment plants. Society’s options for sustaining wild salmon in significant numbers would be just about non-existent.

Whatever policy makers propose to do about the 2008 collapse of West Coast salmon runs, these four facts cannot be ignored. Policy makers should demand from scientists realistic and honest assessments (PDF) of the current and future conditions for salmon.

Joe Friday was a tough, no-nonsense professional. Those of us who provide the public and policy makers with the best available information about salmon ought to follow his lead: “just the facts”.

About the author: Jeffery Robichaud is a second generation scientist with EPA who started in 1998. He serves as Chief of the Environmental Assessment and Monitoring Branch in Kansas City.

Ever heard of a guy named Lew Zealand? He was the Muppet that threw boomerang fish (I expect a cut of your winnings if you ever go on Jeopardy and this bit of trivia pays off). I thought of Lew because it is field season again and on the Missouri River we have our own airborne fish. They are Asian Carp, a particularly troubling invasive species that have infested waters and pose a potentially devastating effect to the Great Lakes. They were introduced into the catfish aquaculture business in the 1970s but during floods these “prisoners” escaped their ponds into the Mississippi River, and have been on the run ever since. YouTube has a lot of great videos of them in action.

In Region 7 we administer our Regional Ambient Fish Tissue (RAFT) program where samples are analyzed for contaminants such as mercury, pesticides, and PCBs. States use the data to post fish advisories. Our biologists (including Lorenzo pictured here) end up with nets full of carp because they often are the most abundant fish in the Missouri River. If you talk to some of the old timers fishing along the banks they will tell you the odd-looking paddlefish were more abundant in years past. Paddlefish face many challenges from human-induced changes to the river such as dams, loss of habitat due to channel straightening, and illegal harvest of eggs for use as caviar. Now they count flying fish as enemies since the more abundant carp out-compete the paddlefish for food.

As comical as the spectacle of jumping fish may be, invasive species are a serious threat. A plant may look pretty and an animal may seem cute, yet they may wreak devastating damage when introduced into a non-native setting. In 1884 a single Australian released twenty-four European rabbits on his property for hunting purposes. Within ten years those 24 had turned into over 2 million, and started the delicate ecology of Australia into a downward spiral causing hundreds of millions of dollars of damage each year and bringing a $30,000 fine for anyone found harboring their own long-eared friend as a pet.
