Black Spruce cones form in clumps high up on branches near the tops of trees.  They are considered serotinous. That is to say, these specialized trees depend on fire to help release their seeds to the world.  The trees bear slowly-opening cones for 25 - 75 - 100 years until a fire sweeps through to rapidly open the cones to disperse their seeds to the charred peat.   They have evolved to survive in a world in which fire is expected – and up here, that return interval is estimated at just over 120 years.   You would be hard pressed to find spruce trees older here in the bogs of Alberta, and we can tell you where a few are, but they are rare rare rare.  We also think that the fire return interval is likely shrinking.  Fires are predicted to increase in intensity and to happen more often. This is all part of the climate story of the world.  

The Fort Mac fire has recently been categorized as being held, and it has surely released a multitude of black spruce seeds – many in our study sites.  It has also burned a bit of our equipment and more importantly, some beautiful landscape is now black and crunchy. The town itself seems to be recovering as well.  They don’t let you into the residential areas that were nearly completely demolished, but the town seems to be chugging along with most things back open.

 

I just spent a few days there with Caitlyn and Wendy and we rolled along the truck-filled roads with our aim on science. We breathed in bad smelling air and watched stacks billow brown tinged ‘steam’.  The big business of oil sands was back up and running.

At Anzac, the first site we visited, the constant buzz of bugs was punctuated by helicopters carrying water bucket after water bucket to nearby hotspots.  Bright green Cloud Berry leaves and Labrador Tea plants were starkly tender on the charred peat; and a month post fire,  where I stood, life was returning.

Along with Anzac, McMurray Bog was also partially burned with the Black Spruce taking the brunt of the damage at both sites. Another site, Mildred, was a total burn.  Two other sites were left unscathed and wait for the next fire to open their cones.  The science moves on. 

These bogs are resilient and I am glad to see that life springs anew sometimes even because of great tragedy.  We will return again in a few weeks and I'm sure we will find new and green freshness springing from darkness.

Mildred Burned

Well, we are pretty solid on our Mildred site burning pretty much as I type this.  It is located very close to the Syncrude/Suncor main stacks and ponds as you can see in the satellite image below.  We had hoped to wander up in that direction tomorrow, but it is looking less and less likely that we will be able to visit any of our sites up there for quite a time.  We will keep you updated.

To the right you can see the overall fire activity this morning.  Today we plan to hit our Red Earth Creek and Utikuma sites which happen to be the furthest sites west and away from this area.  There appears to be a small fire under control north of Red Earth Creek, however, it seems like those sites are all in the clear. 

In other news, it is good to be here in Athabasca again, and the weather is projected to be a lovely 80 F and sunny today.  It is a good day to do field work, but probably not a great day to fight fires.  Keep your fingers and toes crossed.

97 Days

     It takes a lot of work to prepare a research team for a summer fieldwork campaign, but somehow we always manage to do it. The last few weeks have been busy getting paperwork finalized, gathering supplies, tying loose ends, and finding passports. As I was filling out my Canadian customs card on the flight to Edmonton, I was counting the exact number of days I would be staying in Canada before my return to the US, and I concluded that it was ninety-seven days! That is a long time to be in another country, away from home. But the great thing about being here every summer for the past few years is that I feel like Athabasca IS my home. I am very excited to be in Alberta once again, doing the fieldwork that I love so much. Bring on the bogs!

     Hope and I arrived in Athabasca late Thursday night. The weather is warm and dry, with perfectly blue skies. But with warm, dry weather comes wildfire. There was a wildfire raging last week in the city of Fort McMurray, 250 km north of Athabasca, near the oil sands mining operations. All 80,000 residents were evacuated overnight on May 3rd. More than 2,000 homes have been destroyed by fire. While the fire has moved away from the town center it is still burning hot in the surrounding boreal forests. Even now the residents have yet to be allowed back into their community. They are essentially refugees in their own province. 

200,000 hectares of land burned by wildfire in the Fort McMurray region from May 1st to May 8th, 2016.

     There was a Fort McMurray relief concert on Saturday at the Athabasca riverfront. It’s rare that we take time off away from the peatlands to participate in the town’s activities, but this was a good cause to support. There was music, barbecue, and a donation collection to support the fire relief fund. The headlining band was a group of Fort McMurray musicians, calling themselves the Fort Mac Refugee Band. Athabasca may be a small, but the people sure know how to support each other in times of need.

     We are lucky to be working with the wonderful people at Athabasca University. Everyone has been so helpful with getting us set up in our house and allowing us to store our trucks during the winter, and even offering to help us bring our equipment out of storage. The facilities office at AU is the best.

     Hope and I are getting things ready for the arrival of the rest of the Villanova team including Mikah, returning grad student, Wendy, prospective grad student, 2 undergrads from Villanova, Libby and Yevgeniya, and an undergrad from Virginia Tech, Caitlyn. As well as the usual suspects, Kel, Melanie, and Kim. We look forward to meeting up with the rest of the summer 2016 crew.
