On The Green Road: Post-Hawaii Musings

Tuesday, July 15th, 2008

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.

coqui frogThe 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!

Flying Fish

Tuesday, July 8th, 2008

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.

Photo of Lorenzo holding large Asian Carp near waterAs 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. For those outdoor enthusiasts among you, consider scanning your State Conservation Department’s website before you head out on vacation this summer. Find out what you can do to make sure you don’t unknowingly take home a hidden hitchhiker.

Keep the coquí alive!

When my friend Jeff M. came back from Hawaii, he mentioned the Hawaiian-Puerto Rican controversy over the tiny Puerto Rican frog, the coquí-the Eleutherodactylus coquí.

The controversy or “national conflict” depending if you ask a Puerto Rican, made front page headlines several years ago when Puerto Rico got wind of Hawaii’s efforts to eradicate these innocent Puerto Rican frogs. How did they travel thousands of miles across the oceans? Apparently some innocent coquís got on a plant shipment from the tropical paradise in the Caribbean to a similar paradise thousands of miles away in the Pacific. Needless to say, in that tropical setting without any indigenous predators, these Puerto Rican coquis have multiplied abundantly!

photo of a coqui frogThese small frogs are known for their melodious nocturnal sounds in Puerto Rico. They have been the inspiration for numerous songs, stories, and poetry. These small amphibians have become an unofficial symbol of Puerto Rico. In fact, I just read a newspaper article in Puerto Rico, that the Sierra Club-PR and the University of Puerto Rico hosted an Earth Day event to promote the defense of the coquí.

Yet, the coquís-named after their musical chirping-cokée, cokée–have not received a warm aloha from our fellow U.S. citizens in Hawaii.

In fact, what is music to the ears of many Puerto Ricans became more than a amphibian cacophony over in the Pacific. In Hawaii, the coquí chants have been compared to the noise pollution caused by lawn mowers! That’s hard for me to conceptualize, given the fond memories of listening to the coquís at nighttime. I remember many a rainy night falling asleep to the symphony of these harmless creatures. They are so small and defenseless! But for the residents of the state of Hawaii, the Puerto Rican coquís are doomed for complete eradication and some of the methods are not benign at all

It’s true that the Puerto Rican coquí has become an invasive species in Hawaii, yet I still don’t see how coquís challenge Hawaiian wildlife. I still cannot understand why their chants are not music to the ears of the inhabitants of this Island State. Sad to say, it all boils down to one man’s friend is another man’s foe.

Nonetheless-please save the Puerto Rican coquí.

¡Qué viva el coquí!

Cuando mi amigo Jeff M. regresó de Hawaí, mencionó la controversia entre Hawaí-Puerto Rico sobre la pequeña ranita puertorriqueña, el coquí-Eleutherodactylus coquí.

Esta controversia o “conflicto nacional” si le pregunta a un puertorriqueño, fue motivo de titulares de primera plana hace varios años atrás cuando Puerto Rico se enteró de los esfuerzos hawaianos por erradicar estos pequeños anfibios. ¿Cómo viajaron miles de millas por los océanos? Aparentemente unos inocentes coquíes estaban en un cargamento de plantas que viajaron del paraíso tropical en el Caribe a otro paraíso semejante miles de millas de distancia en el Pacífico. ¡Demás está decir que en ese entorno tropical sin enemigo autóctono en Hawaí, estos coquíes se multiplicaron abundantemente!

photo of a coqui frogEstos pequeños anfibios se caracterizan por los sonidos nocturnos en Puerto Rico. Han servido de inspiración a numerosas canciones, cuentos, y poesías . Estos pequeños anfibios se han convertido en un símbolo extraoficial de Puerto Rico. De hecho, acabo de leer un artículo de periódico anunciando que el Sierra Club-PR y la Universidad de Puerto Rico auspiciaron un evento del Día del Planeta Tierra para promover la defensa del coquí.

Sin embargo, los coquíes-conocidos por su melodioso cantar-coquí, coquí-no han recibido un caluroso aloha de sus conciudadanos estadounidenses en Hawaí.

De hecho, lo que es música para los oídos de muchos puertorriqueños se convirtió en una cacofonía anfibia allá en el Pacífico. ¡En Hawaí, el cantar del coquí ha sido comparado a la contaminación de ruido ocasionado por las cortadoras de césped! Me es difícil conceptualizarlo dado los gratos recuerdos de escuchar a los coquíes al anochecer. Recuerdo muchas noches lluviosas quedarme dormida con la sinfonía de estas criaturas inofensivas. ¡Son pequeñas e indefensas! Pero para los residentes del estado de Hawaí, los coquíes puertorriqueños están condenados a erradicación completa y algunos de los métodos no son nada de benignos.

Es cierto que el coquí puertorriqueño se ha convertido en una especie invasora en Hawaí, pero todavía no veo cómo los coquíes amenazan la vida silvestre hawaiana. Tampoco entiendo el por qué su cantar no es música para los oídos de los habitantes de este estado isleño. Lamento decir, que la controversia se limita al hecho de que la criatura que es amiga para unos resulta enemiga de otros.

Independientemente de la clasificación-ayuden a salvar al coquí puertorriqueño.

Song of the Coquí

As we celebrate the 38th anniversary of Earth Day, I remember when I studied at the Academia San José in Puerto Rico and the events that inspired me to strive for greater environmental protection.

In the U.S. territory of Puerto Rico, a beautiful Caribbean island, one enjoys good weather all year round. Beautiful beaches, a colorful scenery, the melodious nocturnal songs of the coquí* Link to EPA's External Link Disclaimer, the Yunque Rainforest Link to EPA's External Link Disclaimer, the Camuy Caverns Link to EPA's External Link Disclaimer- these are some of the images and sounds that live in my memories of my island. In spite of these beautiful surroundings, Puerto Rico faces great environmental challenges-excess of solid waste, lack of landfills, trash along its beaches, problems with the quality of drinking water-these are only some of the factors that undermine its natural beauty.

Academia San JoséWhen I was the president of the ASJ Science Club more than three decades ago, we were decorating an enormous bulletin board for Earth Day. We also planted a tree, I think it was an oak, in the front garden of the school. Today, 34 years later, the tree still stands-a testimony of what some students interested in sciences did one beautiful spring afternoon.

That brings me back to today’s subject - my interest in environmental awareness. That is the seedling that I seek to plant for children and adults so that they may understand that our actions, be it at home, in school, in the community or our workplace, have an impact in our surroundings and above all in our environment. From putting aluminum cans in a recycling bin, buying green products or conserving energy, all these actions enable us to leave the world better for future generations.

Let’s celebrate Earth Day every day anywhere in the world!

*The coquí is a small frog that lives in the tropical trees and shrubs in Puerto Rico. It has been the inspiration for many songs and poetry on the Island.

Cantar del Coquí

Mientras celebramos el 38vo aniversario del Día del Planeta Tierra, recuerdo cuando estudiaba en la Academia San José en Puerto Rico y los eventos que me inspiraron a dedicarme a la educación sobre la protección ambiental.

En el territorio estadounidense de Puerto Rico, una bella isla caribeña, se disfruta una temperatura cálida todo el año. Hermosas playas, bellos paisajes de vivos coloridos, el melodioso cantar nocturno del coquí* Link to EPA's External Link Disclaimer el Bosque Nacional Pluvial del Yunque Link to EPA's External Link Disclaimer y las Cuevas de Camuy Link to EPA's External Link Disclaimer–son algunas de las imágenes y sonidos que viven en mis recuerdos de mi Isla. A pesar de esos bellos alrededores, Puerto Rico enfrenta grandes retos ambientales-exceso de desechos sólidos, escasez de vertederos, la basura en las playas, problemas de calidad del agua potable–son tan solo algunos de factores que minan esa belleza natural.

Academia San JoséCuando era la presidenta del Club de Ciencia en la Academia San José más de tres décadas atrás, estábamos preparando un enorme tablón de anuncios con carteles alusivos a la protección del Planeta Tierra. También sembramos un árbol, creo que era un roble, en el jardín al frente del colegio. Hoy, 34 años más tarde, el árbol sigue allí-un testimonio de lo que hicieron unas estudiantes interesadas en las ciencias una bella tarde de primavera.

Eso me lleva otra vez al tema de hoy-mi interés en crear consciencia a favor de la protección ambiental. Esa es la semilla que quisiera sembrar para que tanto niños como adultos puedan comprender que las acciones que nosotros tomamos, sea en el hogar, en la escuela, en la comunidad o nuestro lugar de trabajo, tienen un impacto en nuestros alrededores y sobre todo en nuestro ambiente. Desde echar las latas de aluminio en la cesta de reciclaje, comprar productos “verdes” o conservar energía, todas estas acciones nos permitirán dejar un mundo mejor para futuras generaciones.

¡Celebremos el Día del Planeta Tierra todos los días en cualquier parte del mundo!

*El coquí es una pequeña rana que vive en la arboleda y flora tropicales de Puerto Rico. El coquí ha sido inspiración para muchas canciones y poesía en la Isla.
