Susan posed an interesting question to me yesterday. How has the record rainfall in the U.S. effected our amphibian friends? Humans have been somewhat inconvenienced by the cool, rainy summer of ’09—canceled picnics, damp weddings, rainy vacations, and decreased sales of ice cream. But as I’ve found out, all this rain has been a boon for amphibians. Here are a few stories from around the country:
Georgia: This summer Southwest Georgia was soaked with rain, but this helped researchers with the Georgia Department of Natural Resources, who released over 1000 gopher frog tadpoles in a seasonal pond at a Nature Conservancy site. These rare stubby, nocturnal frogs spend most of their lives in gopher tortoise burrows and are found almost exclusively in the Coastal Plain’s longleaf pine ecosystem.The water level of the release pond was at its highest level ever, which will help the tadpoles survive, according to an article on the Early County News, GA website.
West Texas: It’s usually pretty hot and arid in the summer in West Texas. But in an article in the Odessa American (TX), Ken Broadnax explains how this dry land can be temporarily transformed into a wetlands. The playas, dry areas with hard clay bottoms, can store water for months. Amphibians bury themselves in the playa, emerging only when conditions are right. After a storm, within a day or two, the male toads emerge and begin their calls, seeking a mate. This summer, West Texans are hearing the unfamiliar sounds of croaking toads.
Florida: According to the AccuWeather blog, rainstorms around Memorial Day caused an excess of standing water, which created a breeding haven for the 30+ species of frogs in Florida. These rain-filled ponds called vernal pools lack fish because they eventually dry up, and so they are ideal nurseries for tadpoles (fish eat tadpoles). All those baby tadpoles from spring are now adult frogs—and there are lots of them. Frog calls are most abundant in the mating season, but they can be heard year-round in Florida for some species. So that’s why some Floridians are being kept awake this summer by the high-pitched calls of the Ornate Chorus Frogs, among other frog choirs.
New Jersey: This summer has been so wet in New Jersey that I’ve rarely had to water my garden. In the early summer, we found a slug in our kitchen almost every night. Maybe even the slugs were tired of the rain. While this rainy weather was depressing (it’s over, thank goodness), it was great for New Jersey amphibians like the endangered Pine Barrens tree frog, as reported in the Press of Atlantic City. The Nature Conservancy recently acquired some land in the Pine Barrens that contains many vernal ponds. Because of the record rainfall, one of these ponds now measures 30 feet, providing an excellent breeding area for the endangered tree frog.Vernal pools are disappearing throughout New Jersey because of overdevelopment. That gave me an idea…perhaps we can convince The Boss (aka Bruce Springsteen) to get involved in our cause!
Have you noticed an increase in frogs and toads in your area due to record rainfall?
