Endangered Species

The International Union for the Conservation of Nature added the migrating monarch butterfly for to its "red list" of threatened species and categorized it as "endangered" — two steps from extinct.

The nest contained more than one hundred eggs laid by a Kemp’s ridley sea turtle — one of the most endangered sea turtle species in the world.

Environmental groups say it’s far too early to change the conservation status of the tallest and rarest birds in North America. Around 500 cranes currently make their way from Canada to the Aransas National Wildlife Refuge every winter.

A company partly based in Austin, known for his pioneering work in genome sequencing and gene splicing, hopes to genetically resurrect woolly mammoths.

Two pairs of whooping cranes nested on private land in Jefferson and Chambers counties this year. It’s believed to be the first time the endangered birds have nested in Texas since the 1800s.

A bill filed to reduce federal oversight of the Texas fossil fuel industry could also force the closure of one of the state’s most iconic swimming holes.

The changes will restore protections that were taken away under former President Donald Trump. But they will take time, and wildlife advocates say many bird species already face a risk of extinction.

The U.S. Fish and Wildlife Service said other species are "higher priority" for listing as threatened or endangered.
