Dear Southeast Neighbors and Friends,
I thought the little chunk copied below from the Long Tom Watershed Council March Newsletter was evocative, and of interest for we stewards of the upper Amazon.
FYI, the entire Watershed Assessment including maps can be downloaded from:

Our Long Tom Watershed Assessment describes our historic riparian areas in great detail. In one example, it states "...that species in the Long Tom Watershed have adapted to and come to rely on the conditions that existed in pre-settlement times.
For example, riparian zones along Amazon Creek, which used to be wet prairie, provided habitat for many wetland plants and animals. During the winter, Amazon Creek widened into a shallow lake, more than half a mile across.
These annual floods carried and deposited nutrients and sediment onto the floodplain before retreating in late spring. Many types of plants and animals adapted to this cycle. Juvenile fish could hide from predators in the shallow, vegetated floodplain. Waterfowl raised young and feasted on wetland plants and insects.
In contrast, riparian zones in the Coast Range foothills provided different kinds of ecological functions. Their towering canopies provided shade, which helped to keep air and water temperatures cool. Large conifers that fell into the stream trapped gravel and slowed stream flow, which benefited native cutthroat trout."
