Restoring An Urban River
Those of us who grew up in Los Angeles are quite familiar with the L.A. River. It’s not much of a river at all. Just a 51-mile-long concrete drainage ditch that shows up from time to time in movies like The Italian Job and Terminator 2.
Amazon In Peril
A constitutional amendment being discussed in the Brazilian Senate threatens to set back decades of conservation efforts in the Amazon.
Size Matters
One of the crowning achievements for wildlife protection in the US was the establishment of the National Wildlife Refuge system in the 1930s, when the populations of waterfowl were perilously low. Refuges provided breeding and migratory habitat that has allowed a remarkable recovery of many species of ducks and geese.
Giant Pandas And The Endangered Species List
Giant pandas are among the most beloved animals in the world and are the iconic symbol of China as well as of the World Wildlife Fund, the global NGO dedicated to wildlife conservation. In the mid 1990s, the population of wild pandas dropped to as low as 1,000 as a result of habitat loss, habitat fragmentation, and an intrinsically low birth rate. There is also illegal poaching despite severe penalties. Pandas have been considered to be an endangered species for quite some time.

Some Good News For Monarchs
Spring is the time of the great monarch migration when the butterflies leave their wintering grounds in Mexico and head north to Canada. As we have been saying for quite some time, fewer and fewer butterflies have been making the trek each year. Twenty years ago, a billion monarchs swarmed the winter site in Mexico. In 2013, the number was down to 33 million.
A Bad Year For Rhinos
The number of African rhinos poached in 2015 set a new record, according to the International Union for Conservation of Nature. Some 1,338 were killed, which is the highest level since the current poaching crisis began in 2008. Since that time, nearly 6,000 African rhinos have been killed.
Keeping A Pulse On Our Planet
The discovery of acid rain in North America was made possible by environmental data collected at a biological field station nestled in the White Mountains of New Hampshire. Hubbard Brook Experimental Forest is just one of the many biological field stations located around the globe that are keeping a pulse on the health of our planet.
Ending The Protection Of Grizzly Bears
Grizzly bears, also known as North American brown bears, once roamed much of North America and symbolized the continent’s untamed wilderness. But hunters and trappers nearly wiped them out across most of the Lower 48 states by the late 1800s.
Ecotourism And Endangered Species
Ecotourism is increasing on a global scale. Ecotourism is generally defined as responsible travel to natural areas that conserves the environment, sustains the well-being of the local people, and involves interpretation and education. Visitor numbers to many protected areas around the world are expanding every year. Ecotourism provides rich experiences for the traveler and often has great benefits to local communities fighting poverty and seeking sustainable development.
River Conservation And Hydropower
Rivers concentrate the water and resources of an entire region. They are literally the lifeblood of much of the world’s fish population. They are also the fuel for hydropower, a critical energy source for human civilization.
Natural Geoengineering
The term geoengineering has started to appear in discussions about how to combat climate change. Mostly, it is used to describe using technology to tinker with the global environment, for example, by artificially enhancing the atmosphere’s ability to reflect the sun’s rays back out into space and thereby cooling the planet.
The Complicated Case Of Cecil The Lion
The recent killing of Zimbabwe’s Cecil the Lion sparked a world-wide reaction and has focused a great deal of attention on the ethics of trophy hunting. There is no question that trophy hunting is an extremely polarizing issue and there are demands around the world to curtail the practice.
Tech Advances Provide Window Into Wildlife
Since the evolution of our earliest ancestors, people have looked to clues – such as footprints in the mud or rubs on trees – to gain insight into wildlife behavior.
