The Bats and the Bees

“We know the losses of bats in the West will be less conspicuous than in the Northeast, where thousands of dead bats are spilling out of cold, dark caves and across the countryside.”

Bees seem to get all the good publicity. In the past few decades, we’ve gone from fear of marauding hordes of killer bees to concern about the decreasing populations of the cute and fuzzy pollinators. But what about bats? These nocturnal creatures, who like to spend their days hanging upside down in dark caves, are creepy and scary. (Except, of course, a certain crime-fighting comic superhero.)

Bats have a good side, though. In their nighttime wanderings, they feast on mosquitos, including mosquitos carrying West Nile virus. They consume pests and insects to the benefit of cotton and corn crops. Recent studies estimate bats provide pest-control worth nearly $4 billion in the U.S. More importantly — to some — they pollinate the agave plant, the ingredient necessary for tequila. They do the same for Arizona’s official state cactus, the saguaro. In Austin Texas, they entertain locals and tourists with their evening emergence from under the Congress Street bridge. They provide similar entertainment in other cities.

Bats’ ravenous appetite for bugs, encourages many homeowners to make their properties attractive roosting places for bats. And there is no documented proof that a bat caught in your hair has dire, even fatal, consequences.

But now bats are threatened by the spread of white-nose fungus.

It’s Easy Being ODOT Green

“My best poem, a prayer in steel.” – David Steinman on the St. Johns Bridge

It’s easy being green… if you’re a bridge.

St. Johns Bridge – Portland

I was surprised the first time I saw the Golden Gate Bridge; surprised because I was expecting it to be painted gold. Some patient person explained to me that the bridge was so named because it spanned the Golden Gate between the Pacific Ocean and San Francisco Bay.

It’s Not Easy Being Salmon

The acidic cormorant poop threatens to mess up a $75 million paint job that drivers across Washington and Oregon are paying for through gas taxes.

For salmon, if it’s not one thing it’s another.

In the Klamath River Basin straddling the Oregon-California border, salmon compete with onion, potato and wheat farmers for the ever-scarcer water. Dams on the river have also contributed to the decrease in the salmon population. Further north, sea lions from California(!) travel all the way up to the Columbia River to feast on the salmon returning to their spawning grounds. That’s if a few years earlier they escaped predation by cormorants as they made their way from the river to the salt water of the Pacific.

(Fun Fact: The name “cormorant” is a contraction of the Latin words corvus and marinus which taken together mean “sea raven.”)

Some preventive cable maintenance.

Replacing the “Haul Rope”

According to Portland Aerial Tram, each tram cabin travels along two cable “tracks” with a moving haul rope between them that pulls the cabin along. The Portland Aerial Tram regularly maintains this essential rope when the tram is closed on nights and during weekends, but the haul rope needs to be replaced approximately once every two years. With more than 21,800 operational hours and 325,000 tram trips logged, it’s fair to say that this particular component is nearing the end of its rope and needs to be replaced.”

Are You What You Eat?

Plastic? In My Beer ! ? ! ?

Yes, we know there’s a lot of plastic in the ocean. We’ve seen the news reports about plastic in whales’ digestive systems and sea life tangled in plastic waste. That’s the big plastic. The micro-sized plastic? We’re eating and inhaling it.

Plastic? In My Beer ! ? ! ?

A study published by the American Chemical Society reports that in a year’s time we consume about 100,000 pieces of micro-sized plastic, most too small to be visible. The study estimated that adult men, on average, would eat, drink and breathe in 121,664 particles during a year — that’s 333 per day — while women would take in 98,305 — 270 per day. The numbers are projected from more than 3,600 samples of items, including air, alcohol, bottled water, honey, seafood, salt, sugar and tap water.

The production of plastics still increases every year, so researchers are not surprised that it is finding its way into our food chain. The research is in its beginning stages and scientists speculate that our actual plastic intake is really much more than what they have found so far. Beef and pork, for example, have not yet been studied. Nor have processed foods which are likely to be a bonanza of plastics.

Plastic? In My Beer ! ? ! ?

Researchers say they do not yet have enough data to speculate on what this means. Maybe we’ll learn that eating plastic is good for us.

So far there is no Recommended Daily Allowance (RDA) for plastic.
