  • Steve Lewis, Raptor Management Coordinator, U.S. Fish & Wildlife Service used leg snare traps and also a net launcher to capture bald eagles on the Chilkat River in the Alaska Chilkat Bald Eagle Preserve. Pictured here is a leg snare trap attached to a driftwood log. Leg snare traps employ a lopped cord draped over a hinged perch. When a bald eagle lands on the perch a spring is sprung which tightens a looped cord around the bald eagle’s legs. The trap was used to capture bald eagles for a study being conducted by Rachel Wheat, a graduate student at the University of California Santa Cruz. Wheat is conducting a bald eagle migration study of eagles that visit the Chilkat River for her doctoral dissertation. She hopes to learn how closely eagles track salmon availability across time and space. The bald eagles are being tracked using solar-powered GPS satellite transmitters (also known as a PTT - platform transmitter terminal) that attach to the backs of the eagles using a lightweight harness. During late fall, bald eagles congregate along the Chilkat River to feed on salmon. This gathering of bald eagles in the Alaska Chilkat Bald Eagle Preserve is believed to be one of the largest gatherings of bald eagles in the world.

  • Steve Lewis, Raptor Management Coordinator, U.S. Fish & Wildlife Service used two types of traps to capture bald eagles on the Chilkat River in the Alaska Chilkat Bald Eagle Preserve. At left is a camouflaged net launcher, and on the driftwood log at right is a leg snare trap. The net launcher uses three projectiles that are attached to a large lightweight net. A salmon carcass is used at bait in front of the launcher. A radio-controlled trigger to launch the net is used when an eagle lands next to the bait. Leg snare traps employ a lopped cord on a hinged perch. When a bald eagle lands on the perch a spring is sprung which tightens a looped cord around the bald eagle’s legs. The two types of traps were used to capture bald eagles for a study being conducted by Rachel Wheat, a graduate student at the University of California Santa Cruz.

  • Dylan Burbank (left) and David Campbell, fish technicians for the non-profit Northern Southeast Regional Aquaculture Association, Inc. (NSRAA), use a large net to catch chum salmon trapped in a temporary weir located on the man-made spawning channel of Herman Creek near Haines, Alaska.<br />
<br />
NSRAA built the channel to collect wild broodstock by harvesting spawning female and male salmon for their eggs and milt to artificially spawn wild chum salmon. The eggs are fertilized with milt and placed in stream-side incubation boxes on Herman Creek and the Klehini River. In 2014, 2.4 million eggs were seeded into these incubation boxes. The 2013 incubation box survival rate was 90%. Without the artificial spawning, natural survival is said to be only 10%.<br />
<br />
Based in Sitka, Alaska, NSRAA conducts salmon enhancement projects in northern southeast Alaska. It is funded through a salmon enhancement tax (of three percent) and cost-recovery income. NSRAA also produces sockeye, chinook, and coho salmon.<br />
<br />
Male chum salmon return to Herman Creek to spawn with female chum salmon during the fall chum salmon run. The chum salmon return to freshwater Herman Creek, tributary of the Klehini River after living three to five years in the saltwater ocean. Spawning only once, chum salmon die approximately two weeks after they spawn. <br />

The electric fence is powered by a Kyocera Photovoltaic Module (Model KC5COT) solar panel that is connected to a fence battery system manufactured by Taylor Fence, Inc. (Cyclops Power on Demand Brute Battery). The 10,894-acre Tallgrass Prairie National Preserve is located in Chase County near the towns of Strong City and Cottonwood Falls. Less than four percent of the original 140 million acres of tallgrass prairie remains in North America. Most of the remaining tallgrass prairie is in the Flint Hills in Kansas.

The 10,894-acre Tallgrass Prairie National Preserve is located in Chase County near the towns of Strong City and Cottonwood Falls. Less than four percent of the original 140 million acres of tallgrass prairie remains in North America. Most of the remaining tallgrass prairie is in the Flint Hills in Kansas. Tallgrass Prairie National Preserve is the only unit of the National Park Service dedicated to the preservation of the tallgrass prairie ecosystem. The Tallgrass Prairie National Preserve is co-managed with The Nature Conservancy.

  • The historic limestone ranch house at the Tallgrass Prairie National Preserve in the Kansas Flint Hills was built by cattleman Stephen F. Jones and completed in 1881. Jones only occupied the house for 5 1/2 years. The house's Second Empire architecture with its mansard roof is noted for its adaptations for prairie life and was considered a showcase at the time.

  • Butterfly milkweed (orange flowers) and wild alfalfa are some of the wildflowers seen along the Fox Creek Trail in the Tallgrass Prairie National Preserve in the Kansas Flint Hills. Butterfly milkweed is also known as pleurisy root. It was named this because American Indians and settlers used the plant's roots to treat respiratory illness.

  • Smooth brome grass grows in the lowland prairie area along Fox Creek in the Tallgrass Prairie National Preserve in the Kansas Flint Hills. This view, seen from the Fox Creek Trail, is indicative of the type of cool-season agricultural hay grass that the National Park Service hopes to replace with true warm-season prairie grasses in an effort to restore the lowland prairies to their natural state. Bottomland (floodplain) prairies are rare because most have been plowed for farming. Bottomland prairies provide deep soil, allowing prairie grasses and other plants to grow much taller than on the upland prairie.

  • The seeds of eastern gamagrass (Tripsacum dactyloides) emerge in the lowland prairie area along Fox Creek in the Tallgrass Prairie National Preserve in the Kansas Flint Hills. The large seeds of eastern gamagrass are used by many birds and small animals. This warm season grass is indicative of the success of the restoration efforts in the Fox Creek lowland prairie area of the preserve.

  • Yiwei Wang, graduate student, University of California Santa Cruz, uses a spotting scope to check on leg snare traps placed on logs in the gravel bar of the Chilkat River. The traps are being used to capture bald eagles that will be used in a study being conducted by Rachel Wheat, a graduate student at the University of California Santa Cruz. Wheat is conducting a bald eagle migration study of eagles that visit the Chilkat River for her doctoral dissertation. She hopes to learn how closely eagles track salmon availability across time and space. The bald eagles are being tracked using solar-powered GPS satellite transmitters (also known as a PTT - platform transmitter terminal) that attach to the backs of the eagles using a lightweight harness. During late fall, bald eagles congregate along the Chilkat River to feed on salmon. This gathering of bald eagles in the Alaska Chilkat Bald Eagle Preserve is believed to be one of the largest gatherings of bald eagles in the world.

  • Rachel Wheat, a graduate student at the University of California Santa Cruz holds one of the solar-powered GPS satellite transmitters (also known as a PTT - platform transmitter terminal) that will be attached to the backs of bald eagles in her bald eagle migration study. The 2.47 ounce transmitter, attached with a lightweight harness, will allow Wheat to see how closely eagles track salmon availability across time and space. The transmitter will record location and other information every hour during daylight hours. That information is uploaded to the ARGOS satellite system into a database where the information can be downloaded for mapping and further study. The eagles in her study were trapped, measured, banded, and then released with the transmitters in the Alaska Chilkat Bald Eagle Preserve near Haines. During late fall, bald eagles congregate along the Chilkat River to feed on salmon.
