Protection of streams from FORESTRY (and other land uses) tends to leave buffers around larger streams
Often we have little or no real protection around source areas
Could we do better at protecting source areas, and what would be the relative costs?
Once sediments and nutrients enter the source streams, the water is heated by solar radiation in summer, and organic matter sources are altered, is there any point to leaving protection around larger streams?

OBJECTIVES (WPs)
1. Develop process-based models to compare outcomes (local and catchment scale) of different scenarios for streamside protection. This will be integrated with an economic analysis of costs of the different scenarios.
2. Augment data available for models by a sampling program carefully structured to expand the range of ecosystem variants sampled and to account for underlying environmental gradients, which can modify specific responses to forestry.
3. Develop a white paper for the options for riparian management around small streams.

Different buffer widths on source streams
Different arrangements – specific reaches
Variable widths

These model outcomes will be integrated with an economic analysis of costs of the different scenarios.
Costs of operations differ by protection measures and landscapes

WP3. 3. Develop a white paper for the options for riparian management around small streams
Riparian management guidelines have often been adopted from other jurisdictions …
Not accounting for underlying environmental differences
Not tested in new places
Need to account for different ecosystem values
