Collecting tree data
Hello Southmoore,
Yesterday and this morning we went out to the forest and collected data regarding the trees in a mature subplot in the woods. We had to collect several pieces of information. Each tree with a "diameter at breast height" of 1 centimeter or greater was identified and tagged with a number and the x and y coordinates of the tree within the 10 square meter subplot were determined and recorded. On my team you will see Janice (Lousianna), Stacey (New York) and Jackie (Texas) collecting and recording data. Between yesterday and today our teams tagged over 200 trees for this study. In five years the data will be collected again to find out how the trees in the area have changed. One of the scientists who assisted us today, Rebecca Wadler told me that it has been predicted the data that our teacher teams are helping to collect would take a single person 30 years to collect. Since Earthwatch brings volunteers into the field, data collection should take about 1/6th of that time.

That seems really interesting.
today in class we learned that a seed gets all it's matter from carbon dioxide and grows into a tree.

I think it's a really good thing that multiple people are taking their time to analyze and take observations about our environment so that we have a clear idea about what is going on.
What exact change are you looking for in the trees?
PS: seems like you're having a good time. Its weird in fifth hour with the lights on
What do you mark the trees with? Whatever it is must have to be pretty permanent because after five years of all the weather it would be hard for it to not wear off!
The researchers here are tracking how the biomass changes. How much growth is going on. They want to find out which trees grow/get larger in diameter over the course of the 5 year study period. We mark the tree with little tags, some are on wires like a little necklace, larger trees we attach the tag with a nail. I will get pictures of this for you today. Thanks, Zach, Lauren, Chris, and Amelia for your comments
