Field Work in the Rain

Today we went out to one of our data collection sites, "Rocket Lake." It started out as a beautiful day, at almost 50 degrees and sunny. I was in a group with 4 other teachers and we were working on collecting data on trees and plants in the forest, forest-tundra, and tundra zones. We were doing what is called point centered quarters, where we find the nearest seedlings, saplings, and adult trees to different points that have already been set up using GPS coordinates. We started in the forest and my job was crawling around looking for tiny seedlings in between other plants that looked almost exactly the same. Most of the seedlings were less than 2 cm (less than 1 inch) tall. The researchers can use the data we collected to find out how well different plants are going in these biomes, and how fast they are growing, or how fast their growth rate is changing, as the climate changes. When we started out in the forest, we saw lots of trees, but as we moved closer to the tundra, we saw less and less. Even the trees we did find were very short and stunted. Look up a definition for "tundra" and see if you can tell me why you don't think there are any tall trees there.
While we were out on the tundra, it started to rain. It was very windy and with no protection from any trees, it felt almost 20 degrees colder (the wind chill was 29 degrees) .  We tried our best to keep doing our data collection, but as it got dark from the clouds and the rain was blowing across the tundra, it got very difficult to see anything. The teacher who was writing down our data, Mr. Griffith (who teaches in Brooklyn), had to try to cover up under a poncho to keep our paper dry. We finished up our data collection for the day, then went back to the study center to dry off and warm up. (I'm actually in this picture too!!)

What's up Doug
Tundra is a treeless plain especially of arctic regions,
I got that from the dictionary. But i already know what tundra was. There was no tree there because it was to cold for the tree to grow faster and also because tundras have grass rather than trees.

What's up Doug?
How are you doing? We agree with Joshua because we looked up the definition for Tundra and we also think that there are no tall trees there because it is too cold and the ground may be frozen.

Here are some questions we have for you today:

What kinds of trees grow in the forest?
-Wilfredo

How long were you crawling around looking for seedlings?
How many seedlings did you find?
- Judex, Louis, Shaimek

What time does it get dark up there?
-Sandy

How did you know I got a haircut?
-Judex

We hope to hear from you soon!

Hello Ms. Kaplan's class and Joshua,
You guys are right. The arctic tundra (where I am) has a layer underneath the soil called permafrost. This is ground that is always frozen all year round and may only be 25 cm (less than a foot) below the surface. Trees can't grow roots here or get any water, so they cannot live there. Also, the tundra gets about as much rain as a desert every year, and it had nearly constant winds as high as 60 miles per hour, which makes it a tough place for plants and trees to try to grow, especially tall ones that require a lot of resources (like water).

The trees we have here in the forest are almost all white spruce, with a few black spruce and larch trees. Larch trees are conifers (think Christmas trees) but they lose their needles every fall like the other deciduous trees you usually see changing colors and dropping their leaves in the fall.

I was crawling around looking for seedlings all day yesterday (even in the rain on the tundra) and until lunch today. We found 36 seedlings for our study, but they each were an average height of only 8 cm so it could take up to half an hour to find a single one in the forest. It was easier to find them in the tundra where less trees and tall plants could hide them, so that part went faster.

It gets dark here about 7:30, but when it gets dark, it is REALLY dark. We can see so many more stars, especially shooting stars, up here because there are no city lights to block them out. This is really cool to see, but it is almost impossible to walk outside without a flashlight, because you cannot even see your hand in front of your face.

And Judex, I know things. That's just how teachers are.

Thanks for all the questions, I can't wait to hear from you guys again soon!!
