Overall between the call to action in 2007 and 2019 there has been a 57% increase in number of breeding programs, or 77 additional species. [48] Areas with noticed frog extinctions, like Australia, have few policies that have been created to prevent the extinction of these species.
A population that was once in the tens of thousands was down to a mere 3,000. [13] The largest known chorusing groups persist in Bastrop County, but the choruses monitored in Bastrop State Park showed a dramatic decline during the mid-1990s, with little recovery of those numbers since then. Importantly, that state park is the only public land ...

Officials say the crawfish frog likely was at the site during that period, as well, and remained in place until the mid to late 1980s, when they "vanished suddenly and mysteriously, possibly ...
A 2019 Science review assessed that chytridiomycosis was a factor in the decline of at least 501 amphibian species during the past 50 years, of which 90 species were confirmed or presumed to have gone extinct in the wild and another 124 had declined in numbers by more than 90%. [37]
The Sierra Nevada Yellow-legged frogs were almost wiped out of Yosemite National Park. But these scientists mounted a wildlife comeback. 'The lakes are alive again': These frogs are back from near ...
Unlike Megalocytiviruses, however, Ranavirus infections in amphibians have been implicated as a contributing factor in the global decline of amphibian populations. [ 3 ] [ 4 ] The impact of Ranaviruses on amphibian populations has been compared to the chytrid fungus Batrachochytrium dendrobatidis , the causative agent of chytridiomycosis .
Watch the "Today" show team — Savannah Guthrie, Hoda Kotb, Al Roker, Craig Melvin and Carson Daly — reflect on how much has changed in the past year.
