Texas Takes to the Air to Reduce Feral Swine

The article, in the Fort Worth Star-Telegram says it’s war. More than two million feral swine in Texas are causing half a billion dollars of damage, uprooting everything from crops to tombstones in cemeteries. The latest weapon: the “pork chopper,” helicopter hunting trips recently approved by the state legislature.

An hour on the chopper costs $475, and the firm that runs the trips requires hunters to take $350 hunting safety course. Most hunters book a five or six hour flight, the article says.

About 15,000 feral swine were killed through the program last year. The numbers have declined through each of the three years of the program. For the rest of the details, read the article here.

Why Did the Turtle Cross the Road?

Actually, “Where are the turtles crossing the road and getting hit by cars?” is the focus of a Massaschusetts citizen science research project, and it is one of several turtle research projects going on in this year of the turtle. For more info, read this article on the Massachusetts turtle road-crossing project in the Springfield Republican.

Here are seven other sources of information on turtles and turtle research:

Maryland Amphibian and Reptile Atlas (MARA), a five year project that began in 2010 and will end in December 2014.

The USA Turtle Mapping Project is being run by the US Forest Service’s Pacific Northwest Research Station. It is focusing on seven species of freshwater turtles and tortoises to find out their current ranges.

Not surprisingly, PARC, the creator of Year of the Turtle has a list on its Web site of turtle citizen science projects. It’s a PDF. Here are some of the US-based land- or freshwater turtle projects on the list that aren’t already mentioned:
Blanding’s Turtle Research – Great Meadows, Massachusetts
Gopher Tortoise Tracker – Volusia County, Florida
Lake George Turtle Monitoring Program – Lake George, New York
North Carolina Museum of Natural Sciences Neighborhood Box Turtle Watch
Western Pond Turtle Presence, Absence Monitoring Project -Ventura and Santa Barbara Counties, California
Texas Turtle Watch 

Another resource on the PARC Year of the Turtle site is an Excel spreadsheet of 87 relocation, reintroduction, translocation, and headstarting projects. Turtles make up more than half of these projects, the rest are for other reptiles and amphibians. The idea, the site says, is to allow scientists running similar projects to get inside information on what worked and what didn’t so future projects can build on the past.

When it comes to turtles, the news is pretty bad, but it’s not all bad news. In June so many diamondback terrapins headed upland from Jamaica Bay in New York City that a runway at Kennedy Airport was closed. Here’s a news story, and background information from the journal Science.

We don’t normally cover research outside the US, but since we gave wildfires in the West so much coverage earlier this year, and because it is the year of the turtle here’s an exception. A paper in the journal Biological Conservation says that a species of tortoise in Spain can withstand wildfires every 30 years or so and still maintain its population levels. Read an article about the study in Science Daily, or the whole paper in Biological Conservation (or rather, read a free abstract and pay for the whole paper).

Finally, don’t forget our mini round-up of box turtle data earlier this year. You can find that post here.

Don’t mess with invasive plants in Texas

Giant salvinia in Caddo Lake

The Texas Parks and Wildlife Department reports that last year’s campaign to increase the public’s awareness of the invasive aquatic plant giant salvinia reached more than half of its intended audience. Of the boaters living within 60 miles of four lakes in east Texas who saw an ad or information about giant salvinia, 96 percent said they were “more likely to clean their boat, trailer or gear….”

Giant salvinia (Salvinia molesta) is a native of Brazil that came to North America as a plant for water gardens. It can grow up to three feet thick, and can double in size in a week. It has plagued the lakes of eastern Texas for over 10 years, and is also found in Alabama, Arizona, California, Florida, Georgia, Hawaii, Louisiana, Mississippi, North Carolina, and South Carolina.
According to a department release, the campaign included floating messages on buoys near key boat ramps, fish measuring rulers with campaign messages, online web banner ads, Twitter and Facebook posts, gasoline-pump toppers, billboard ads near key lakes, and a cute television public service announcement (PSA) that personifies giant salvinia as a doofus hoping to hitch a ride with a boater to cause trouble in other lakes.

The campaign was so successful that the department may try a similar effort for zebra mussels, which are not yet as established in the state as giant salvinia.

Read the full press release here. You can find the press releases, radio spots, a PDF of the ruler, and two versions of the television PSA here.
