Welcome to our new post in this post, we talk about 70 Yellow Legged Frog released . In Southern California, a species of frogs whose future was once uncertain may now have hope for survival in the jungle, thanks to a multi-agency breeding and reintroduction program.

More about Yellow legged frogs
Recently, more than 70 yellow-legged mountain frogs, which are endangered, made their homes in a lake in the San Bernardino Mountains. Wildlife biologists will be keeping an eye on these frogs to make sure they survive.
According to a press release from the San Diego Zoo Wildlife Alliance’s Conservation Alliance, this marks the first time that this species has been reintroduced to a lake rather than a mountain stream in Southern California.
The non-profit conservation organization, the alliance, collaborated with Omaha, Nebraska’s Henry Doorly Zoo and Aquarium to breed and raise medium-sized frogs in their native environment before releasing them.
Due to obstacles, the population of mountain yellow-legged frogs, which are distinguished by their characteristic yellow skin and are the offspring of two species, has decreased.
According to the California Department of Fish and Wildlife, both species were formerly common in Southern California’s and the Southern Sierra Nevada’s high mountain lakes, ponds, and rivers.
However, due to human encroachment, dams, climate change, and pollution, their population has decreased.
According to the International Union for Conservation of Nature’s Red List, the number of endangered Southern mountain yellow-legged frogs has seen a significant decline since the 1960s, with around 500 individuals able to reside in their original habitat. While other populations in the Sierra Nevada are not currently at risk, the species as a whole is declining and has been listed as vulnerable.
Debra Shier, the San Diego Zoo Wildlife Alliance’s Director of Conservation and Research, underlined the significance of breeding programs for these species as a result.
Shier stated, “It is crucial that we are identifying and protecting suitable habitats in the original range of mountain yellow-legged frogs for breeding and reintroduction programs for this species in the coming years.”
Breeding of the yellow-legged frogs took place between 2020 and 2022.
Since the initiation of its program in 2006, the San Diego Zoo Wildlife Alliance has successfully bred thousands of frogs and reintroduced them to high-altitude mountain habitats. The most recent breeding, between 2020 and 2022, occurred at the San Diego Zoo Safari Park in collaboration with the Beckman Center for Conservation Research of the Wildlife Conservation Alliance.

Lead keeper “Derek Benson” of the Henry Doorly Zoo and Aquarium said, “We are dedicated to helping conserve these frogs, and our special ability to work remotely as part of the Conservation and Reproduction Recovery Team is invaluable.”. As the population grows, we are excited to be part of the return of these animals to a historic site.”
Once more than 70 frogs were ready, the wildlife team released them in two waves onto the San Bernardino Mountains. The first group arrived on the day of their release from Omaha and was kept in a secure enclosure by the lake for seven days as they acclimated to their new environment.The group fed the frogs a variety of insects that they collected from their environment while keeping a regular eye on them throughout the week.
The second group of frogs arrived the following week and was released into the lake alongside the initial group. This was the first time the team released frogs into a lake rather than a stream.
With lakes less likely to dry up during dry spells, the Wildlife Conservation Alliance plans to assess the efficacy of the microchip-tagged frogs in order to decide which reintroduction approach is better.
According to Shier, lakes have the benefit of having more steady water, which lessens the chance that they may dry up during droughts.
In places like lakes where there is less water than there is for adult frogs, tadpoles cannot migrate.”
This discovery offers optimism for the survival and eventual return of the Southern mountain yellow-legged frog to its native habitat, marking a major achievement in the species’ preservation.
