We first camped where the Twin Otter dropped us off, and stayed there for a while. There were many close research sites and our work was slow at first as we were figuring out efficient ways to complete our research. The first time we moved camp, we canoed from the west end of Jolly lake […]
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 […]
One of the things we were interested in was the growth patterns of shrubs in the Bathurst Caribou herd range. Specifically, we wanted to know how climate has affected shrub growth. We have already looked at the greening patterns in the satellite data, but the shrubs themselves have a story to tell us. At each […]
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%.
This is our first camp on the west end of Jolly Lake. Although we didn’t have twenty-four hour sunlight at this latitude, it didn’t get really dark until closer to the end of the trip. This photo was taken at 10pm.
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!
