The Extinct and the NY Times

We're all aware of human-caused extinctions, with famous species like the passenger pigeon, the dodo, and Steller's sea cow as poster creatures. Where are we now in terms of our impact on vulnerable species?
Obviously, a lot of things are better than they were decades ago. In the U.S., the EPA was created with the power to list species at risk and direct preservation efforts. Truly extraordinary efforts saved the California condor, the Florida panther (still very close to the edge) and the whooping crane, but were apparently a little too late for the Eastern cougar, the ivory-billed woodpecker, and Eskimo curlew.  
The New York Times makes it easy to see all its stories on this topic.  The "paper of record" is a bit battered these days by controversies inside and out, but the science coverage remains definitely worth reading. Stories the classification of tigers, which is am interesting reminder that DNA evidence, which itself is objective and information-stuffed, still needs to be interpreted by the slightly fuzzy standards of a "species" and the very fuzzy standards of other taxonomic levels. Some say there are only two subspecies of Panthera tigris, while others vote for six. We know the Sumatran, which some experts call a separate species, is extinct,  as is the Javan tiger and maybe the Caspian tiger.  
Balancing this sadness is some rare (very rare) good news on the vaquita, the world's most endangered marine mammal, with a sighting including a calf.  
Other recent articles cover the biodiversity of reef communities, the establishment of Madagascar's extinct elephant birds as the largest birds ever (800kg is a lot of Thanksgiving dinners), and how the Asian market for sea cucumbers threatens species off Mexico. 
Finally, there's an obituary I missed, for an Interior Department official named Nathaniel Reed.  I can't remember whether I met Nat Reed, but when I was active in Florida politics he ran for governor. He lost the primary to Congressman Lou Frey, who was stomped into oblivion by Lawton Chiles, but that's aside from the point: the point is that he was instrumental in establishing the EPA and drafting, then pressing for passage of, the Endangered Species Act under the Nixon administration.  Richard Nixon didn't particularly care about the environment per se, but he wanted to be known as a champion of it, and he and Reed, to whom he gave a free hand, did some real good.  He stopped the plan for a major airport in sensitive habitat of Big Cyprus Swamp and co-founded the Everglades Foundation.  He was 84.  Goodbye to a good man.
