Fieldwork for this project took place through summers 2018 and 2019, visiting sites in the MacKay Lake and Daring-Yamba lakes area to sample shrubs for the growth ring component of this project. Trees were sampled opportunistically from the study areas. New in 2019, we also sampled vegetation at several plots to investigate how vegetation communities […]
As we canoed toward an esker on the east end of Jolly Lake, we noticed a Twin Otter fly over and land near our desination. Strange… And then there was another. As we got closer to shore we could see people moving around and a large tent set up. After no sign of civilization for […]
We didn’t get to pick where we wanted to hike to each day. Our research sites were determined by satellite maps of greening or non-greening areas (explained on the satellite page). Sometimes getting to these sites was challenging. There were wetlands, rocks, streams, and hummocky terrain, and birch and willow thickets that we would hike over […]
I can’t say I wasn’t warned. Tree dendrochronology was pioneered in the early 1930’s by A.E. Douglass, who then founded the Laboratory for Tree-Ring Research at the University of Arizona. Since that time, tree rings have been used in archaeology, chemistry, ecology, and biogeography to reconstruct the timing of past events. Growth rings in trees […]
The Government of the Northwest Territories censused the Bathurst herd in summer 2018, and the results are alarming: www.cbc.ca/news/canada/north/caribou-herds-decline-2018-1.4913934. From a half a million caribou when the population last peaked in 1986, the herd now stands at 8,200 individuals, a decline of 99.9%.
We’ve been back for almost two months now, and data entry is underway! For my personal project, I am looking at seedling dynamics at northern treeline. More specifically, I’m looking at what makes a certain spot more favourable for a seedling to grow compared with where seedlings are not growing. While the team was up […]
It has been six weeks since we returned from fieldwork, and I am now four weeks into the first term of my PhD studies. Much personal time has been spent catching up with family and friends, and school life has occupied even more time with administration, coursework, and scholarship applications. But here and there I am […]
After 36 consecutive days in the field, we returned to Yellowknife on Monday, August 20, stepping off the plane somewhat hairier (quick, admire the guys’ neck beards before they’re gone!) and substantially grimier than when we left. But, all of us satisfied at having completed a safe and successful field season: We visited ten (10) […]
Since we are studying change, we thought it would be valuable to have a picture of our field crew before we depart for five weeks. Consider it a photo for posterity, so you can see how we undergo our own changes in the wilds of Northwest Territories!
A bit of time in Yellowknife before we depart (Monday morning is coming quickly!) and so I thought I would share our general route plans for this summer. The map below gives an idea of our research area and our planned route (red line). Our team of 6 are flying into Jolly Lake via a DHC-3T Turbo […]
