Algae Is Killing The Sea Otters

Suprised Sea Otter

Maybe is was better when Round Up was used near the shore.

Microcystin, which is commonly referred to as blue-green algae, can cause liver damage when ingested. All 21 sea otters that tested positive for the bacteria died from liver failure, according to the study, which was completed with the help of experts from UC Santa Cruz and a variety of state and federal agencies.

It is believed the toxins flowed to the ocean off the coast of Monterey in rivers and creeks. Sea urchins and shellfish near the outflow filtered the water and the poison accumulated in their bodies, which were, in turn, eaten by otters.

Marine Mammals, Birds Affected by Algae Bloom

Large blooms of algae in Monterey Bay are releasing a toxin that has apparently been poisoning large numbers of marine mammals and birds.

Blooms of the algae produce a neurotoxin called domoic acid, said Tim Stephens of the University of California-Santa Cruz, whose scientists report that the blooms which first appeared in Southern California earlier this spring are now occurring along the Central Coast.

Researchers have detected high levels of the toxin in the bay, he said, and large numbers of dead seabirds, as well as sea lions with symptoms of domoic acid poisoning, have been turning up on Monterey Bay beaches.

“The impact on marine life depends on how much of the toxin gets into the food web,” said Raphael Kudela, associate professor of ocean sciences at UC-Santa Cruz. “But in terms of toxin production and the size of the bloom, this event is similar to the large blooms we saw in Monterey Bay in 2000 and 2002.”

Serious – nature does things that appear cruel.
Silly – maybe Round-Up herbicide in the ocean would kill the algae.

P.G. Public Works Commits Herbicide

Dead Ice Plant

Dead brown dirt surrounds Washington Park’s picnic benches and tables in Pacific Grove. Weeks earlier, groundskeepers doused sprouting weeds with such a wash of Roundup that passerby Ximena Waissbluth thought they were watering the ground.

“It’s never really occurred to me why there is no grass there, until I saw the enormous quantity of chemical they use,” she said.

Ximena makes it sound like they are pouring straight DDT on the ground. Roundup is diluted with water.

Would you rather have tall brown weeds amongst the picnic areas that could easily catch fire?

Tidepool Nazis favor erosion instead?

Dead Ice Plant

Pacific Grove has halted spraying invasive iceplant with a well known herbicide because of concerns by environmentalists the chemical could harm endangered species and the coastal environment.

P.G. City Council requested Rana Creek, the Carmel Valley environmental planning company hired to restore the dunes, provide a report that includes the effects of Roundup, a commercial herbicide, on the environment.

“To kill this much iceplant,” said Lee Willoughby, one of several Pacific Grove residents concerned with the use of Roundup, “there has to be some runoff, and it goes right into the tidepools. I think it’s a major concern.”

Former Pacific Grove City Councilwoman Susan Goldbeck wrote a letter to the city requesting more information about the use of the herbicide.“Of particular interest is,” Goldbeck wrote, “who is doing the Roundup and when are the planned applications?”

Rana Creek is currently preparing the report, which will be presented to council members March 7.

Bruce Cowan explains in great detail in a letter from the Carmel Pine Cone

What does glyphosphate do? It is an enzyme inhibitor in the photosynthetic pathway (shikimic acid pathway) that prevents the formation of lignins. Plants normally convert sugars (simple carbohydrates made in photosynthesis) to complex chains of carbohydrates (cellulose, lignin). Animals do not make cellulose or have cellulose in their tissue structure; it is only found in plants, fungi and bacteria. Without cellulose or lignins, plants collapse and die. Animals don’t have cellulose or that photosynthetic pathway, so glyphosphate is without effect.

Ice Plant Killed For Native Weeds

Dead Ice Plant

Five years ago, a wallflower that grows only on the sand of local dunes nearly disappeared.

Only five Menzies wallflowers held out, the rest snuffed out by decades-old patches of ice plant in the ground at the Point Pinos Lighthouse in Pacific Grove.

But today, more than 130 of the flowers are growing at the city’s golf course. Another 250 will be in the ground soon.

Ahh! Food for deer, attracting more mountain lions.
