The restoration of Pinzón Island continues following the successful rat eradication campaign in December 2012, carried out by the Galapagos National Park Directorate (GNPD), in collaboration with Island Conservation and The Raptor Center. In addition to the exciting news of natural recruitment of juvenile tortoises into the population, a potentially new endemic snail species has recently been discovered.

The Galapagos National Park Directorate (GNPD) is partnering with CABI and the Charles Darwin Foundation (CDF) to help protect the iconic Galapagos Islands from an invasive blackberry (Rubus niveus). This non-native plant was introduced in 1968 and is causing serious problems for local biodiversity and agriculture. It is now considered one of the worst weeds affecting the islands.

In 1946 the Argentine Navy imported 10 beaver couples from Canada and set them free in Isla Grande, the deep south of Tierra del Fuego, with the intention of "enriching" the native faunaand the local fur industry. The consequences of such initiative were disastrous: Protected from hunting for 35 years, and devoid of natural predators, the beavers grew over 5,000 times their initial population, caused irreversible changes in the forest ecosystem, and started advancing over the continent. Now, a study published in Chilean Natural History suggests that the demographic explosion of those beavers could be bigger than suspected because it can take years or even decades for local inhabitants to notice the rodents' presence and their impact on the surrounding ecosystems.
North American beavers have wiped out 30 percent of forests along rivers and streams in Tierra del Fuego, a remote archipelago at the southern tip of South America, causing the greatest landscape change to these fragile forests in the last 10,000 years. It’s no surprise, then, that the governments of Chile and Argentina want the invasive beavers gone. But eradicating them has proven to be difficult, researchers found, because it requires the participation of every single landowner in the area.
