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.

Bears, Fluxing, and Fert

Well, the fire still burns, but we are busy with our fieldwork and the team is gaining momentum.  Two teams today split up and one fluxed and one fertilized.  It was a busy, successful day.  We had hoped to get to Fort McMurray by now, but access is still restricted and so we continue to focus on our NSF project.

By my count, we have collectively seen at least 4 bears – one of which came walking by our front door and explored the yard.  That is a seriously respectable number for our short stint  up here thus far.  We’ve seen a host of fox, several coyote, tons of deer – some of which have decided to race our trucks and then cut us off – some of which are in our front yard.  We’ve seen so many birds of all kinds, and squirrels and we’re pretty sure there is a wolf skeleton at one of our sites.  We are teaming with all kinds of wildlife and I hope to see more. 

I’m at the end of my first trip up here for the summer, but really it is just the start for us all.  The crew is great - Tough and Smart and Funny and hard working and they still seem to all be enjoying themselves, so that is a good start.  

Cheers to a great summer!   

Science On

Thanks, Kelly, for your great update yesterday!   Athabasca has been our home for a long long time and I look forward to joining Kelly and Hope on Tuesday to start our field season.  Our hearts go out to the people of Fort McMurray, many of whom still do not know if they have homes still standing or a place to return to.  They all wait for word that they can head back to Fort McMurray to see what the fire has left them.

We, too, await word.  We are starting our field season, and it is shaping up to be an odd and possibly treacherous one.  Field work, in general, trends to the tenuous, and we have had to wait to get up to some of our sites before because of fire, but this year is beyond precedent.  We have two sites that may have burned.  We won’t know until we show up.  One is just south of the airport and one is just north of Anzac.  The MODIS satellite imagery has them both questionable. Our sites are the green dots in purple lettering.

Two of our bogs (green dots) amid a see of yellow, orange, and red dots indicating age of fire with red being most recent...  Image was taken off Google Earth May 5th.  The fire has spread into and off the borders of this image since.

This fire season is already in full swing and it is only May.  This year it officially started in March, and since then, the area has seen 30+C weather and a paucity of rain.  The fire threat is Extreme for all of our field sites currently, and the Fort McMurray fire is still burning, and, as of this morning, is just over 251,000 hectares large with several areas still out of control.  There are currently over 1,000 firefighters and firefighting personnel, 134 pieces of heavy equipment, 39 helicopters, and 11 airtankers working on this wildfire, alone.  It remains impressive and devastating and we are holding our collective breath.

All this being said, we are still looking forward to the new field season and I’m excited to get the crew together to start our work this year in the Boreal.  We return to the house where we were last year, and are lucky to do so.  Our colleagues have not been so lucky – some of whom have lost houses in Fort Mac or the ability to get up to the area to do any of their research.  At least we have several projects still in unburned areas and we can start our work.  I expect there may be some camping happening in the Fort Mac area this summer, as housing will be terribly tight.

We will be sure to keep an eye and nose to the sky and earth as we roll from site to site this summer - especially paying close attention to where we park hot trucks.  Bogs tend to hold onto fire deep into the peat, and so we will be vigilant and mindful of the potential for fires everywhere.   For now, we will do our best to keep the science moving forward.  Sites have burned in the past and sites will burn again in the future and there is always room for more questions to be answered.  So…. With that in mind: 

 Science on, crew!  

We hope to be diligent about our updates this year, so stay tuned!
