Summer on a Shoestring

Research- Part I: Green Leaf Collection

Hi all! So I started my first semester of graduate school working with the MELNHE project (If you need a refresher poke around on here, the bottom line is that we’re doing nutrient manipulations in a forest). Primarily I’m working with Pin Cherry and Beech leaves to analyze them for leaf area and nutrient composition.  The journey started in August when I went up to our New Hampshire experimental forest in the White Mountains. We were using a shot gun to shoot down tree leaves from the canopy. We wanted sun exposed leaves to collect during the growing season so we could compare them to leaves we collect during the fall. Despite standing still trees can be hard to shoot!

This is Dan (first photo in the grey long sleeves), he’s a graduate student who is ahead of me one semester. He’s looking at the same thing I am but with different tree species, White and Yellow Birch. The second Photo is Adam, a previous graduate student and general mastermind for the melnhe project. Ok, mastermind might be a strong word. But he knows all the forest plots and has more knowledge than a newbie! The last picture is me in green. After shooting down some leaves/branches we would select 10-20 leaves that were healthy (in color and size) and lacked holes from shot or herbivory. Then these leaves would be stacked on top of eachother and packaged in a Ziploc bag that was labelled with what tree they came from. The bags will be frozen and were going to be analyzed so we wore gloves to prevent contamination to the leaves.

Overall we collected over 300 samples! It was a lot of fun if you like being outside and staring upwards, which I do, and I’m really good at it because I’m a birder.

It took a long weekend to finish what we came there for. The cool thing about being in the White Mountains is the ability to tent camp and look at other wild life. I don’t just like leaves and birds, I also like moths and bugs!

Waved Sphinx (Ceratomia undulosa, 7787) and a male forked fungus beetle.

Stay tuned! Next time I will answer the question that is keeping you on the edge of your seat – “what did you do with the bags of frozen fresh green leaves??”
