  • Red-legged frogs are listed as threatened under the Endangered Species Act.
  • Gary Kittleson a biologist is trying determine whether the conservation efforts are helping or not.
  • Many steps have been taken to find  the frogs and conserve them.

In the east of swamp in Santa cruz , Califorina,  Gary Kittleson a biologist and young explorer is trying find the rare red legged frogs. A local trust has hired him, to determine whether their number is growing or decreasing.

The Area called Watsonville Slough is a important habitat for the red legged frogs.

These frogs lost their habitat due to over hunting for frog legs and development, and now it is listed as threatened under the Endangered Species Act.

Kittleson says it is not a job to spot frog in thick brush and pick out their sound and differentiate from other frogs. The people who have untrained ears wouldn’t able to do it. But Gary is an expert and is capable listing to them even while talking.

But this method is an old way of counting animals and it requires lot of time and man power too. With just Kittleson one could get only a small size of data because he can’t be there the whole time.

Hence the local trust of Santa Cruz has also partnered with Conservation Metrics a company which specialises in protecting and conserving biological matters. The company and Kittleson have setup song meters – little green boxes with microphones that record all night and capture everything.

Data recorded in the song meter is then uploaded in computer and the company employees little green boxes with microphones that record all night and capture everything.  What would normally take a whole team of field biologists can now be done by one person and a computer says Matthew Mckown CEO of Conservation Metrics.

“Our whole point is to make conservation better, so we are trying to make it as cheap as possible,” he says.

Conservation Metrics was found three years ago. Mckown believes big data is the hot tool in conservation to study endangered animals and threatened habitats.

“What you’re going to start having is cameras, acoustic sensors, satellites trained on these important parts of the world,” he says.

Kittleson stays in the Watsonville Slough where night has fallen and he finally spots one and says “Beautiful. Adult red-legged frog,”

He is not too optimistic about the future of the red legged frogs. But he says good data is the only way to know if conservation efforts are helping.

California’s Net Neutrality Law Causes A Law Suit From The US Government

Oregon, Washington and Vermont have approved legislation related to net neutrality, but California's measure is seen as the most comprehensive attempt.

California Gov. Jerry Brown has approved the nation’s strongest net neutrality law, prompting an immediate lawsuit by the Trump administration and opening the next phase in the battle over regulating the internet.

Advocates of net neutrality hope California’s law, which Brown signed Sunday to stop internet providers from favoring certain content or websites, will push Congress to enact national rules or encourage other states to create their own.

However, the U.S. Department of Justice quickly moved to halt the law from taking effect, arguing that it creates burdensome, anti-consumer requirements that go against the federal government’s approach to deregulating the internet.

“Once again the California Legislature has enacted an extreme and illegal state law attempting to frustrate federal policy,” U.S. Attorney General Jeff Sessions said in a statement.

The Federal Communications Commission repealed Obama-era rules last year that prevented internet companies from exercising more control over what people watch and see on the internet.

The neutrality law is the latest example of California, ground zero of the global technology industry, attempting to drive public policy outside its borders and rebuff President Donald Trump’s agenda.

Brown did not explain his reasons for signing the bill or comment on the federal lawsuit Sunday night.

Supporters of the new law cheered it as a win for internet freedom. It is set to take effect January 1.

“This is a historic day for California. A free and open internet is a cornerstone of 21st century life: our democracy, our economy, our health care and public safety systems, and day-to-day activities,” said Democratic Sen. Scott Wiener, the law’s author.

It prohibits internet providers from blocking or slowing data based on content or from favoring websites or video streams from companies that pay extra.

Telecommunications companies lobbied hard to kill it or water it down, saying it would lead to higher internet and cellphone bills and discourage investments in faster internet. They say it’s unrealistic to expect them to comply with internet regulations that differ from state to state.

USTelecom, a telecommunications trade group, said California writing its own rules will create problems.

“Rather than 50 states stepping in with their own conflicting open internet solutions, we need Congress to step up with a national framework for the whole internet ecosystem and resolve this issue once and for all,” the group said in a Sunday statement.

Net neutrality advocates worry that without rules, internet providers could create fast lanes and slow lanes that favor their own sites and apps or make it harder for consumers to see content from competitors.

That could limit consumer choice or shut out upstart companies that can’t afford to buy access to the fast lane, critics say.

The new law also bans “zero rating,” in which internet providers don’t count certain content against a monthly data cap — generally video streams produced by the company’s own subsidiaries and partners.
