WEEK SIX: DNR Board OKs Removing 16 From Endangered List, Adding 8

http://host.madison.com/wsj/news/local/environment/dnr-board-oks-removing-from-endangered-species-list-adding/article_f0fa56be-78e9-11e1-b66d-001871e3ce6c.html

The DNR Board approved of a new listing of sixteen species to remove, as well as submit a list of eight new species to add to the list. This proposal for added species was opposed by the Wisconsin Wildlife Federation, who stated that the final decision would be delayed because outside experts were not consulted and no plants were added to the list. The DNR responded that these occurred in order to keep cost down, since every species on the list costs money to preserve or recreate habitats and monitor populations. The removal of species from the list will remove funding for that species. Outside experts should be consulted, despite funding issues, because some species may be more endangered than originally thought and may go extinct without funding and attention.


   
Some species to be removed from the endangered list: Barn Owl, Gray Wolf, Snowy Egret, Blanding's Turtle 


     
Some species to be added to the endangered list: Kirtland's Warbler, Ottoe Skipper, Upland Sandpiper, Western Lowland Gorilla

WEEK FIVE: World's Smallest Dolphins Facing "Imminent" Extinction

Maui's dolphins are classified as critically endangered, as there are only 55 left in the world. They only inhabit the west coast of New Zealand. The main cause of these creatures' dwindling population are the many fishing nets along the coast, which catch many of these dolphins and kill them. Researchers have determined that if fishing is not banned in these areas, these dolphins will go extinct in as little as a year. These dolphins have a lifespan of about 20 years, but only reach reproductive maturity after 7 years, and only calve about once every 3 years. There may be as few as 20 breeding females left. If things do not change, they may follow the Baiji Dolphin, once prevalent in the waters of China, in extinction.

The Maui dolphin - the world's smallest - is under threat from fishing and just 55 individuals are left
These beautifully patterned dolphins only grow to about 1.7 meters long.

WEEK FOUR: Underwater Nursery Tends Endangered Corals

The adult staghorn coral is now considered endangered because of tankers that run aground where it grows off Puerto Rico, coral bleaching, and disease. Recently divers have undertaken a new project to save the staghorn coral population, which has declined by 98 percent since 2006. Underwater coral nurseries are being set up in strategic places, where the coral is suspended in the open water, tethered to rubber-coated wires, out of the  reach of predatory snails and fireworms. 100 nursery-raised corals have survived in this area to date, and the number is growing significantly. It is truly remarkable to see people striving to make a difference, instead of just continuing their comfortable life at home.
