Silvicultural Practices, Larnmas growth and stem deformities

Purpose

This project will test the extent that silvicultural practices increase late season flushing of Douglas fir. Herbicide treatments will increase the availability of water late in the season. Fertilizer will increase nitrogen availibility and influence se

Relationships between chlorophyll, spectral vegetation indices, and photosynthetic potential on the Oregon Transect

Purpose

Construct a tower and analyze vertical variability in photosythetic capacity, chlorophyll, nitrogen, and specific leaf area at three points in time- May/June, September and mid-winter. An ultra-light airplane will fly over the site at this time to collec

Lotic Intersite Nitrogen eXperiment (LINXII): Nitrate uptake and retention in streams: mechanisms and effects for human disturbances from stream reaches to landscapes

Purpose

We will doing a stable isotope tracer study to look at uptake, transformation and retention of nitrate in stream ecosystems. This will entail some intensive water sampling efforts on our part, as well as measurements of channel geomorphology and hydrolog
