May to see retirements of two AFES researchers

Two longtime faculty with UAF and the Alaska Agricultural and Forestry Experiment Station will retire in May — Josh Greenberg and Greg Finstad.

Josh Greenberg

Greenberg is a natural resource economist who has been teaching and researching resource topics for 31 years at the University of Alaska Fairbanks. He earned a master’s degree in resource economics at UAF and returned to the university in 1990 after earning a doctorate in agricultural economics at Washington State University. An associate professor, he has taught resource economics, environmental decision making, sustainability and global sustainability, natural resource policy and agricultural concepts.

His research has been equally diverse. Recent projects have evaluated business plans for reindeer meat industry, the feasibility of raising musk ox for qiviut under different scenarios, the effect an industrial road to the Ambler Mining District might have on subsistence communities and the impact of individual fishing quotas on the Alaska sablefish industry. 

Greenberg has specialized in fisheries. His dissertation was a bioeconomic model that looked at the effect of management decisions on the king crab fishery. He studied the demand and allocation of Alaska and Canada snow crab; extending the federal crop insurance program to commercial fisheries; changes in fishery regulations affecting the red king crab; walleye pollock, halibut, tanner and snow crabs and salmon fisheries; and the economics of subsistence bowhead whaling.

Greenberg retires May 8 and plans to move to the Branford, Connecticut, where he and his wife, Andrea, have many siblings, nieces and nephews. They grew up in the area.

 He has mixed feelings about the move. “I really love it up here,” he said. “The university has been a great place.” 

He has enjoyed teaching students and camping, fishing and gardening in Alaska. At the same time, he looks forward to being closer to family, good seafood and New York City.

Josh Greenberg served on the UAF Faculty Senate and most recently chaired the university’s Master Planning Committee.

Greg Finstad has worked on developing a red meat industry in Alaska for 38 years as the head of the university’s Reindeer Research Program. A research associate professor of range ecology, Finstad researched the best combinations of feed and forage, range management and how the reindeer diet and slaughter methods affect the quality of meat.

His research was conveyed through workshops, consultations and the High Latitude Range Management certificate course that he developed and helped teach through the Northwest Campus in Nome.

Challenges to reindeer production in rural Alaska include a lack of slaughter facilities that would allow producers to process reindeer according to state and federal standards. Finstad worked with tribal entities that own herds on the Seward Peninsula and St. Paul and St. Lawrence islands to demonstrate hygienic field slaughter methods. 

He remains optimistic about the development of a reindeer industry and its potential. His research and work by Josh Greenberg, who developed business plans for reindeer enterprises, built a foundation that reindeer operations could use in the future. 

“Everything is there for a group of people to take it on and run with it,” he said. 

After his May 10 retirement, Finstad and his wife, Bev, plan to stay in Fairbanks. A son and a daughter live here, along with three granddaughters, ages 12, 10 and 8.

His said his decision to retire was made in part based on his experience with COVID-19 in the earliest days of the pandemic. He contracted COVID during a trip Outside to attend his father’s funeral, and he nearly died from it. He is what they call a long hauler, someone who continues to feel symptoms of COVID after recovering from the acute phase. He is easily fatigued and has lower energy levels.

He used to use his hard-driving energy to get projects done at night. Now, he jokes, “I am a mere mortal.” 

As a mere mortal, he still has many plans. He and his wife are building a cabin on the Wood River, which flows into the Tanana between Fairbanks and Nenana. He also plans to help his daughter build a house in Fairbanks. He bought a new boat for Valdez and they also hope to travel.  

Good luck to both of these researchers.

OneTree Alaska distributes birch-tapping kits for season

Birch sap will start flowing soon and, starting today, OneTree Alaska will distribute 200 birch tapping kits to Interior residents who are interested in learning about birch tapping. 

 

This year, the kits will cost $40 and participants will have the opportunity to participate in a citizen science activity. The kits come with instructions, gear and a recipe or two. OneTree lead Jan Dawe said One Tree will produce home tapping kits for “all who want to work with their trees, experience the icy fresh taste of sap and try their hand at making birch syrup at home.”

 

Participants may observe, record and submit their daily sap flow data to OneTree. Dawe said the goal is understanding how sap is moving across the Tanana Valley Watershed and how climate change may be impacting early spring events in the annual life cycle of birch. Those who participate will receive a 4-ounce jar of birch syrup.  She would also like to collect data from individuals who received the kits last year and plan to participate again. 

 

Individuals may pick up kits at the OneTree Studio in the Lola Tilly Commons from 4-6 p.m. today, by appointment and will continue each day as supplies last. Contact OneTree at onetreealaska@gmail.com. The entrance is on the side facing Patty Gym. Contact OneTree if you want to arrange a weekend pickup.

 

 UAF climate scientist Rick Thoman has forecast that sap will begin flowing the third week of April and the median forecast date for green-up is May 13, five days later than average.

 

The OneTree program is affiliated with the University of Alaska Fairbanks Agricultural and Forestry Experiment Station. The program provides forest education to students, and conducts research on birch sap processing methods and on the conditions that lead to when sap flow begins and peaks.

Tree ring research provides clues to reconstruct climate

A doctoral student who used facilities at the Fairbanks Experiment Farm to study driftwood logs used in ancient houses in northwest Alaska presented her research at the 21st World Wood Day Virtual Symposium March 21-23.

Archeological timbers were found at
several sites in Northwest Alaska.

Emeritus Professor Glenn Juday said Juliette Taïeb completed tree ring work in 2018 using his lab and wood-handling facilities at the experiment farm.

Her presentation was titled "Climatic value of Thule architectural wood remains from northwestern Alaska (AD 850-1650): a dendroarchaeological approach,"  which she co-authored with Juday and other members of her doctoral committee. Taïeb is studying at the University of Paris Pantheon Sorbonne.

The tree ring research involved the study of driftwood logs used in ancient houses at several sites on the northwest coast of Alaska and the Seward Peninsula area, including old Kotzebue.

Juday described highlights of the research. “We have successfully cross-dated dozens of archeological timbers that now have dramatically improved the sample numbers of ring width chronologies that are available to reconstruct climate from 1000 AD to 1650s AD. Previously only one or two trees contributed to the reconstruction of a few of the early centuries, making the reconstructions weak or suspect. Juliette also extended the cross-dated tree ring chronology back to AD 812, over one additional century from what was available previously.”

She will join Juday and another committee member, Claire Alix, for a joint presentation at the annual meeting of the Society of American Archeology (online) April 15-17.
