Hi! My name is Ms. Hoskins. Please join me while I travel to Maryland to study Climate Change and Fragmented Forests!

Have you gathered any data to support climate change and decline in tree growth?

This experiment will run over a five year period. It will take five years to gather the data and to anaylze the information. They still have several areas to tag trees. The scientists said the yearly data will be available so people can follow along to see what is happening with this forest. They are tagging trees in the old forest (120 years old) and in the new forest (50-60 years old) to compare the two. I believe the first year is not over yet.

How do they determine whether it is poor soil content, contaminated water, or insect damage that is the souce of a tree's destuction?

They are running this experiment over five years and they are still in the first year of the study. If insects are destroying a tree it is obvious as either the insects are present or the scientists showed us where to look on a tree to see evidence of insect damage (bark damage, burrowed holes etc). They are also conducting soil studies (rough woody debris is measured) and they have a 125 foot tower with instruments to measure rain composition, how much water vapor the forest puts out, and how much carbon/carbon dioxide the forest puts out and takes in. The results are beamed to NASA in Washington DC for analysis over the next five year (There is a video at the top of the tower showing some of these experiments). They also have a water weir on one of the streams going through the forest and it takes up samples of water flow and chemical analysis.
