Alex Vaisvil, a student intern from Xavier University in Cincinnati, Ohio, lowers a Lindgren multi-funnel trap to lure longhorned beetles from the mid-canopy in the Tongass National Forest. Traps were located in the forest as part of a study to refine woodborer trapping methods in Southeast Alaska. (U.S. Forest Service/Elizabeth Graham)
Non-native longhorned beetles are easily transported around the world in solid wood packing material, arriving in a new location with no natural enemies to control their populations. Across the country, many of these non-native beetles, particularly the Asian longhorned beetle, have killed tens of thousands of hardwood trees, especially in eastern states.
Will these pests ravage trees in Southeast Alaska? U.S. Forest Service specialists are working to determine ways to prevent the kind of devastation they’ve had elsewhere. Read more »

Since the second week in July, locals and visitors alike have congregated on the viewing platforms above Steep Creek near the Mendenhall Glacier Visitor Center in Juneau, Alaska to enjoy the sockeye salmon migration.
From mid-July through the end of August, the sockeye salmon enter the creek to dig redds (nests), find mates and spawn. For thousands of viewers this annual show is seen not in person but on the screens of their computers or smart phones, thanks to the Steep Creek salmon cam. Read more »

Gordie Reeves looks at salmon the way a man would look at pictures of his family. For Reeves, the salmon species is pretty much the best fish species around.
“They are dandelions of the fish world,” said Reeves, a research fish ecologist with the U.S. Forest Service. “They have this mechanism or strategy for persisting. We are under the illusion that everything in a stream should be perfect all the time, but that’s not true. It’s not the way the world works. Salmon do a terrific job under really incredible odds.”
Nature lovers can get a glimpse of salmon runs through a live streaming video. For the second year, the Forest Service is streaming from the bed of Juneau’s Steep Creek on the Tongass National Forest in Alaska. Read more »

Alaska’s Chugach and Tongass national forests are sometimes referred to as salmon forests, producing all five species of wild Pacific salmon: king, coho, sockeye, pink, and chum.
Salmon is vital to Alaska’s economy, and last year’s statewide commercial salmon harvest is being noted as a banner year. The Alaska Department of Fish and Game announced the salmon harvested in 2013 set a new record at 272 million fish.
About 45 percent, or 122 million, of these commercially harvested salmon relied on habitat managed by the U.S. Forest Service. Much of the harvest consisted of pink salmon, the most abundant of salmon found in Alaska. Don Martin, the aquatic and fish program leader for the Alaska Region, said that 95 percent of the habitat where pink salmon spawn in Southeast Alaska is on the Tongass National Forest. The work of Forest Service fish biologists contribute to the health and viability of these salmon. Read more »
Mount Edgecumbe volcano is on Kruzof Island in Southeast Alaska, just west of Sitka. The Mount Edgecumbe Volcanic Field consists of more than a dozen volcanic vents and domes. The field first erupted more than 600,000 years ago, and volcanic activity continued until 5,000 to 6,000 years ago. (U.S. Forest Service/Jim Baichtal)
Seldom does one find a way to directly date a prehistoric volcanic eruption, but 11-year-old Blake LaPerriere opened such a door for excited scientists in Southeast Alaska.
Last September, Blake, his parents, and his younger brothers were exploring a beach on southwestern Kruzof Island, part of the Tongass National Forest landscape and just west of Sitka, Alaska, where they live. Blake investigated a deeply incised creek behind a pile of beach drift where he found a standing burnt tree embedded in a tall bank of pumice. He brought it to his family’s attention, asking “Do you think that’s from a volcanic eruption a long time ago?”
Curious, Blake’s father Zach took photos and sent them my way. Read more »
The Chugach National Forest BioBlitz – an intense period of biological surveys – included surveys of all organisms in Portage Valley including fungi. Ecologist Kate Mohatt leads a walk for the public to identify all mushrooms fruiting in the valley in 2011. (U.S. Forest Service/ Mona Spargo)
While many people look forward to fall for football rivalries and tailgate parties, others enjoy a different pastime — foraging for fall’s crop of fungi.
In Alaska, the season’s fungi festivals will find enthusiasts lined up for hikes into the woods to search for lichens and forage for mushrooms.
In September, the Wrangell Ranger District on the Tongass National Forest hosted a two-day event near the Rainbow Falls Trail. Karen Dillman, the forest’s ecologist, and Kate Mohatt, an ecologist from the Chugach National Forest, shared a variety of tips and information on fungi with locals and visitors including information profiled in the video “The Mushroom Maven of the Chugach National Forest.” What are the differences between edible and poisonous mushrooms? The pair described how to look for telling colors of the mushrooms after they are cut open, as well as the distinctive features of the caps and ridges. Read more »
