More Details on Protecting Burrowing Owls

Back in 1995, the California Department of Fish and Game released a report on burrowing owls that described how to survey for them and steps that could be taken to mitigate loss of habitat. Yet, the numbers of burrowing owls in California have continued to decline.

A new, 36-page report goes into more detail and incorporates research that has been done since the 1995 report. It includes suggested survey protocols, and buffers for various times of the year.

Role of Predators in Ecosystem Balance

Do wolves and other large predators keep deer and other large herbivore populations in check, or is the food supply that really limits the herbivore population?

Two Oregon State University biologists did a meta-analysis of 42 published studies and found that large predators play a huge role in keeping ecosystems in balance. The analysis spanned North America and Eurasia, which may be why the study was published in the European Journal of Wildlife Research.

But it’s not a single predator alone that keeps the herbivores at levels that allow for a healthy mix of plants to grow, the paper also says. When an ecosystem hosts at least two large predators — such as wolves and bears, or wolves and lynx — each predator has an impact on a different part of its prey’s life cycle, reducing the population more than one alone.

App Happy

You may be using a smartphone to enter data in the field (hey, it beats lugging a laptop), and now the public can get in on wildlife conservation apps, too.

The National Wildlife Refuge System has been busy adding interactive smartphone applications. Patuxent Research Refuge, outside Washington, D.C. and Las Vegas National Wildlife Refuge in New Mexico are putting QR codes at trailheads. The Aransas Wildlife Refuge in Texas, and Great Meadows in Massachusetts, are putting QR codes on visitor brochures, kiosks, interpretive panels and printed trail maps.

That’s in addition to the app the system introduced last year, MyRefuge, featuring maps of scores of refuge recreation trails and other visitor attractions. Also last year, the system introduced the interactive iNature Trail at J.N. “Ding” Darling National Wildlife Refuge in Florida.

There’s more, and you can read about it in the National Wildlife Refuge System press release, here.
Access MyRefuge, here.

The BirdLog apps lets bird watchers (and researchers) enter data into eBird in the field using an iPhone or Android smartphone. An app for iPad is coming soon. A portion of the cost goes to Cornell Lab of O conservation activities.

Getting injured animals to wildlife rehabilitators and keeping the public safe as they try to assist injured wildlife can be difficult. It’s hard to be available 24-hours a day. In the Boulder, Colorado region a new web site and app, AnimalHelpNow, lets people report injured wildlife on their smartphones. The developers hope to have versions for other parts of the country soon.

Read (or listen) to the National Public Radio story on the app, here. Lots of links to follow to get the app and other information.

Finally, it’s not all sunshine and happiness is app-land. New apps that give Yellowstone visitors the locations of bears and other watchable wildlife have park advocates worried. The park’s bear jams are already dangerous, both as a travel hazard and because people get too close to the animals.

Solar Flares Over Desert Protection

Which is more important, to save the global environment or to protect a particular ecosystem?

An article in the Los Angeles Times says that big, national environmental groups are leaning toward saving the planet even at the cost of rare and valuable ecosystems, frustrating local environmental groups who want to preserve those ecosystems.

The current arena is the Mojave Desert, where massive solar projects could provide power to southern California’s throngs, but where the fragile desert and its inhabitants would be better off being left alone.

With the big guns backing the solar projects, the only advocates for animals like the desert tortoise are the small, local enviro groups.
