Dirty Paws and Furry Coat, and the Forest of Talking Trees pt.1

 

Flashback Friday

Forest of Talking Trees

Today I will take you to one of my absolute favorite places in the whole world. My field site, called CPCRW, short for Caribou-Poker Creek Research Watershed.

 
 

    The watershed is mainly black spruce, but also quite an abundance of deciduous vegetation, and have a lot of different small and big creatures. We start going out already in May (sometimes even late April), even though most of the snow hasn't even melted yet. Early in the season most of the watershed is brown and you could still see leftover dead plants from last years summer.

 
 

    The fieldwork doesn't come for free, and if you by chance forget to use mosquito spray you will most likely end up like the pictures below will show. Another thing about mosquitos a lot of people don't understand, if you think there are a lot of mosquitos in the interior and north of Alaska, multiply that by 100 and that is probably closer to the reality. You can not survive without mosquito repellant. 

 
 

    We hike in rubber boots because yeah, we follow rivers. Mosquito spray or a bug shirt is needed.

 
 

We Follow Rivers

    I have a poster I printed with tons of small pictures I have taken in the watershed through the years and through the seasons. I call it "We follow rivers", because that is what we do. We sample water and try to understand how changes in the landscape affect the streamwater chemistry. Alaska is underlained by permafrost, both continuous and discointinuous, and of course the most southern part is permafrost free. Few people comprehend how large Alaska actually is. Like Sweden it's pretty long, but longer of course (1420 miles; 2285km).  Permafrost stores a lot of carbon, old carbon, since it's literally ground that has been frozen (and still is to certain extent) for hundreds and thousands of years. One of the important questions is "How much carbon is being released when permafrost thaws?", because permafrost throughout Alaska is thawing due to the increase in temperature. And of course, we also have the increase in fires and how that actually affects the landscape and stream water chemistry. 

 
 

    We follow rivers and investigate our own research questions and the underlying question about how thawing permafrost affect streamwater chemistry.

Fieldwork in Yellowstone National Park

Where's Waldo?

Hi friends, it's Flashback Friday again

Yellowstone National Park

    Being married to an ecologist has its perks. While we were driving from Alaska to Wisconsin we drove through Montana and Yellowstone. We needed a break and we also needed to check in on some of Ws fieldwork. Both W and I do research about fire, me in Alaska and he in Yellowstone, or jellystone as we sometimes call it. As always when me and W go somewhere, I fall behind because I just can not get enough of all the tiny little things I see, or all the awesome views. 

 
 

Dalahäst    

    Before I moved to Alaska one of my best friends gave me a little miniature "dalahäst" which is a painted horse. Of course that one was with us this day too. Fires can be really destructive, but I think it's beautiful to see what can grow out of a fire. 

 
 

Coniferous Trees

    Coniferous trees are either serotinous, not serotinous, semi-serotinous or a mixture between the two first. In Yellowstone National Park the Lodgepole pine is a mixture between the two first examples and the fire can benefit the reproduction of the forest. Serotinous species are dependent on fire to open up the cones and "activate" the seed, and the opposite is true for species that are not serotinous.

 Hiking in Yellowstone

    I love being able to walk away from the road system and feel like we are in the middle of nowhere. Yellowstone is so huge, and so beautiful, and if you haven't been there yet, its definitely a place to see. Just remember that walking off the main road will show you extraordinary places. I would definitely recommend to do a backpacking trip. However, please don't walk off the road in areas of hot springs...use a map and consult the backcountry office for permits and current conditions, carry bear spray and know your bear safety!

 
 

  Leaving Yellowstone

    When we left the park we used a new (to me) exit, the city of Cody, and the landscape changed drastically. I asked W if he still thought this was grizzly country, because I surely did not think it looked anything like it. Literally 5 minutes later, we see this grizzly below getting up on its hind legs as we approached with the car. He started to cross, before he changed his mind and we could see his friend in the bushes. One of the coolest things I ever seen. Didn't capture him/her getting up on the hind legs, but man that was so cool!

 
 

    Have you ever seen anything cool on a roadtrip, or any other time for that matter?

Something is in the air...

Breaking Records

    A couple of days ago Fairbanks broke yet another record. This Year is really turning out to be some kind of new record year when it comes to long-term monitoring. On May 2nd Fairbanks measured birch pollen at 4290 grains per cubic meter of air. Tanana Valley Clinic has this neat webpage where you can se the daily counts of all the different pollen counts. Now, to put that number in perspective, 175 grains per cubic meter of air is considered high...

    I for once didn't actually notice that there was a big pollen day, and I figured that I am probably more sensitive to one of the other pollen contributors. Today Birch, Spruce and Alder has been high so my guess is that I am either sensitive to Spruce or Alder. 

Science

    When I was googling away I came across an old article about tree pollen, and it showed the general order of the different tree species and their pollen in the Boreal Forest, which I thought was pretty neat. 

    I really wanted to take a picture of the pollen I saw flying around in the air yesterday evening, but didn't really succeed, so I took a picture of my car instead.

    How is the pollen where you guys are at? Some webpages says that Fairbanks broke the world record for birch pollen on May 2nd, but then one page is saying that Denmark had the previous record and another one says Sweden, so I am not sure about that. What I do know is that we did at least break the record for Fairbanks itself.
