GIS, Drones Help Protect Elephants From Poachers

Elephants have some of the largest ranges of any animal in Africa.They can routinely travel 20 to 40 miles in a day. Not surprisingly, this makes for tough work when trying to protect them against poachers. But what if it were possible to pinpoint the high-vulnerability areas and make more efficient patrolling easier? Using a geographic information systems (GIS) approach, researchers from Penn State University set out to test the idea in the Tsavo ecosystem in Kenya. The system is comprised of a number of parks full of dry and flat savannah and home to Kenya’s largest elephant population. It includes Tsavo East National Park, Tsavo West National Park, Chyulu Hills National Park, Ngai Ndethya National Reserve, Taita Hills Wildlife Sanctuary and the Lumo Wildlife Sanctuary.

Flood Warning Systems

Chapter Overview: Flood Warning A Real-Time Solution Streamflow Measurements Typical Flood Warning System Monitoring Location Data Management Quality Assurance Recommended Equipment Why Monitoring Matters While some areas are more prone to flooding than others, the establishment of flood warning systems near any major waterway or body of water provides critical information that can protect property and save lives. Of course, the most effective flood warning methods extend beyond the installation of gages and telemetry equipment, and employ qualified staff and carefully designed procedures to provide the earliest warning about whether a flood should be expected, when it will occur, and how severe it will be.

Pacific Ocean Lingcod Stocks May Benefit From New Gear

Pacific Ocean lingcod used to be overfished, to the point where managers created protected areas for the fish and other depleted groundfish species, such as yelloweye and canary rockfish. Some lingcod have since recovered well with commercial and recreational fishing restrictions and closures, called rockfish conservation areas. These safe zones have given them space to run from predators, as well as the nets of fishermen. But other rockfish species also designated as overfished haven’t yet recovered, even with vast fishing closures. While fishing closures have helped to rebuild some species, others still flounder due to lower reproduction and growth rates.

Lake Mead At Lowest Levels Ever

The story coming out of Lake Mead last year was lower water levels. This year, it’s not much different, except that the water body has continued to go even lower. According to KGW-TV, an NBC affiliate in Portland, Ore. , the lake has hit its lowest levels since it was being filled in the 1930s, during the Great Depression. As of last week, Lake Mead was sitting at 1,074.68 feet above sea level . That breaks a modern-day record of 1,074.71 feet that was set on June 15, 2015. Next year’s predictions for Lake Mead point to even lower levels ahead, according to officials at the U.S. Bureau of Reclamation. They are forecasting that the lake will reach 1,073 feet near the end of 2017, at which time there may be a water shortage declared.
