Apple Moths in New Zealand

While California’s policy is to eradicate the Light Brown Apple Moth, a local researcher reports that New Zealand has adopted other tactics to control the bugs, which have been present in that country for more than a century.

One problem with California’s attempt to eradicate the Light Brown Apple Moth is that the state got a late start in that effort. U.C. Cooperative Extension biologist Lucia Varela says the number and dispersal of the moths suggests they were here for some time before they were discovered.

Right now, California’s official policy toward the apple moths is “zero tolerance,” so that any areas where they are found are place under quarantine. But Varlea and many other experts doubt that the bugs can successfully be eradicated. Instead, she says, a more realistic policy would be to control the apple moth populations, so they cause minimal damage to apples and other crops.

Lucia Varela also reported recently  on the arrival of the European Grapevine Moth in the North Bay. You can hear the North Bay Report coverage of that development here.

It may take a lifetime to see the results, but students replanting a native oak forest near Glen Ellen are taking the long view.

"The Dangerous World of Butterflies"

 Nature lovers versus breeders. Preservationists versus poachers and smugglers.  A history that goes back eons versus threatened extinctions in the 21st  century. These are just some of the stories that lie within the dangerous world of....butterflies?

 Here on the west coast, we enjoy seeing the annual migration of the brilliant orange monarch butterflies, some of which gather in certain trees at the Bodgea Dunes state park on the Sonoma Coast.  But the Monarchs of eastern North America have a longer and far more remarkable migratory cycle.

 

Researching and writing this book on butterflies has opened his eyes in unexpected ways, Peter Laufer (left) says, but it also served to fulfill the unarticulated wish behind the impromptu remark that first set him onto that path.

 

 

 

This video compresses the life cycle of the Painted Lady butterfly into less than three minutes of striking time-lapse photography.

From PeterLaufer.com:

War weary after writing a book about Iraq, Laufer joked before an audience that his next book would be about butterflies. The result: an invitation to a butterfly preserve in Nicaragua. There he stumbled into a theater of intrigue full of strange and nefarious characters-all in pursuit of one of nature's most delicate creatures.

 

The Dangerous World of Butterflies chronicles Laufer's unexpected discoveries in the butterfly industry and underground. Readers will learn everything there is to know about the beauty and magic of butterflies. But Laufer's narrative takes unpredictable turns into the high-stakes realms of organized crime, ecological devastation, species depletion, natural history museum integrity, and chaos theory. Set in locales throughout the Americas and beyond, this fascinating book takes us into a behind-the-scenes world sure to alter our view the next time we delight in the colorful fluttering of butterflies in our yards.

 Butterflies are enormously popular, and have been for centuries, but not everyone loves them. There is even a website for people who are repelled by them.

Recording Nature in the Tetons

You have to get up pretty early to capture the pure sounds of nature… and get a long way away from the rest of the noisy human race.

Gina Farr of Wild Sound Stories in Marin County finds a poignant significance in these recent recordings, because the changes they document tell a story of losses that will not be recovered.

This is one of her summer 2009 recordings of birds in the Grand Tetons of northwest Wyoming:

Tom Rusert, an avid birdwatcher and the volunteer director of Sonoma Birding, joined in the June workshop to see firsthand how the sounds now increasing featured in birding guides were being collected.

Hundreds of shorebirds were covered in oil after the Cosco Busan oil spill in the San Francisco Bay. Many died, but some were saved. Here, International Bird Rescue Association volunteer Tom Rusert releases one of the very first stricken shorebirds back into the wild after being cleaned.
