To combat ocean acidification in Washington, the state needs to better track the changing chemistry of Puget Sound, reduce stormwater runoff and nutrient pollution that worsen the problem, and counteract souring waters by sprinkling shells in estuaries or growing more carbon-gobbling vegetation.
But above all, the state must advocate for regional, national and international policies to reduce carbon-dioxide emissions, according to authors of a first-of-its-kind report released Tuesday about the changing chemistry of Washington's marine waters... Read more.
As our plane topped the Peruvian Andes, I looked out the window and caught my first view of the headwaters of the Amazon. The green canopy of the rain forest spread out in all directions. Yet on closer examination, I noticed the wilderness was marred by a checkerboard of cleared fields, scarred stream banks and rivers stained brown by polluted runoff.
Naive tourists that we were, my wife, Micaela, and I were starting a visit last month to the Madre de Dios region of southeastern Peru, near the border of Bolivia. Our destination was Tambopata National Reserve, a lush sanctuary that is considered one of the most biodiverse places on the planet. After landing, we traveled by boat up the Tambopata River, where we would spend the next three nights in rustic cabanas outfitted with mosquito nets and candles... Read more.
Is it time to consider a new cowboy for the 21st Century?
Is this the moment for ranchers and conservationists to seek a new direction?
The Society of Range Management is commemorating a century of their science, which like forestry and other early conservation studies was devoted to maximizing resources for human use. Western rangelands then were suitable for only raising livestock.
The best science, a term we love today, in the terms of range, was the classification of rangelands based on livestock carrying capacities, amount and type of forage available, and climatic and other conditions that affect their value to ranchers.
Rangelands are no longer viewed only as a source of livestock feed. Other ecological services, wildlife, water, biodiversity, renewable energy and open space even carbon sequestration are now valued.
If range management is changing maybe ranching can change to. Maybe it’s time to turn ranchers into rangers... Read more.
Some catfish in France’s Tarn river come on land to hunt pigeons. Those catfish and their unusual hunting behavior is the topic of a new study.
The European catfish are native to Eastern Europe. They were introduced by anglers to the Tarn river in Southwestern France in the 1980s. They have only recently developed the habit of pouncing on unsuspecting pigeons hanging out by the water.
