Threatened frog species on the road for recovery in Alberta

One of Alberta’s most risky amphibians is making a comeback.

Provincial efforts to help the northern leopard frogs have been successful in establishing new self -reliant population, According to Alberta Government,

The northern leopard frogs, listed as a dangerous species in Alberta since 2004, were once relatively common in most parts of the province. A significant population declined, firstly noted in the 1970s and 1980s, focusing on frog protection operations.

In the species of wildlife biologists at risk with the province, Brett Bucle said that re -construction efforts have focused to translate frogs, or released eggs in new areas to create new population.

“When the efforts of its translation were first placed, the population of the northern leopard frogs in the province looked so good,” he said.

“Since then, we have been able to determine a large number of populations spread over a broader distribution and the southern part of the province.”

The renovation was successful at Battle River, Kinbrook Island Provincial Park, Bewice Lake Provincial Park, Gringer, and Winham-Karseland Provincial Park, the biologist confirmed the presence of a population of self-sufficient northern leopards at those places.

Bukell said, “Translating eggs proved to be quite successful in establishing new population of northern leopards frogs at different access within their former limits,” said.

Successful frog resurrection, in association with the existing northern leopard frog populations, naturally found in other parts of Alberta, this means that the province will not need to introduce more population for time.

A total of 163,880 tadpols were introduced as part of the translation program between 2007 and 2010, and from 2013 to 2014.

“Increasing stability we are looking into the northern leopard frogs and their distribution can allow us to start saying, well, our population is recovering,” said Buclele.

Why did so many frogs crack?

Once the dramatic decline of the northern leopard frogs of the mangoes has not yet been confirmed by the province, Bukell said.

Professor Emeritus Synthia Paszkovski, University of Alberta Ecology, said that when the AMFIBAM population declines, there are “a lot of smoking guns” to consider.

“There are many clarifications for this, being a few habitals, pesticides, herbicides, in chemicals from the environment,” he said.

He pointed to other factors such as the disease, the destruction of the habitat, and the northern leopard frog’s residences, which had no fish earlier, which led to limited oxygen in the water.

These factors may lead to rapid rash in the amphibian population in North America, said Paszkovski.

“Interestingly enough, there are many areas in North America where the leopard frogs have recovered from these historical dips,” he said. “But in Alberta, they are not really, and that is why the province is trying to re -present them in areas where they feel that there is still a proper residence.”

Paszkowski said that the availability of appropriate houses in the historic range of frogs has been an advantage of re -production program.

He pointed to the three elements required for the frogs, which to establish a successful self -sufficient population: a reproductive habitat, overwintering residence, and then terrestrial habitat to food.

Alberta is the home of eight frog species: borial chorus, Columbia spotted, northern leopard and wooden frogs, as well as Canadians, Great Plains, Spadfoot of Places and Western Todd.
