FIGURE SET 2
-
Figure 2. Precipitation, stream flow, net export of nutrients and particulate matter, and
aboveground production in 2 watersheds in the Hubbard Brook Experimental Forest.
Watershed 2 (open circle) was clearcut in 1966 and herbicides were applied monthly
from fall of 1966 to winter1969. Watershed 6 (closed circles) remained unaltered.
Nutrients and particulates were measured in a stream draining the watershed. Data
are a composite of (From Bormann and Likens 1978. Recovery of a deforested
ecosystem. Science 199: 492-496).
More figures and photographs can be found at the Hubbard Brook Case Study: http://www.cnr.umn.edu/forestecology/lecture40_ppt.pdf or at http://links.jstor.org/sici?sici=0036-8075%2819780203%293%3A199%3A4328%3C492%3AROADE%3E2.0.CO%3B2-D.
