wetlands in the vicinity carry out three general biogeochemical functions""

#NAME?

21

specific conductance

a measure of the total concentration of dissolved substances

22

wetlands in the project vicinity carry out three general flora and fauna habitat support functions""

- wildlife habitat diversity- connectivity of wetland wildlife corridors- aquatic habitat diversity

23

Overall goal of the mitigation program""

To compensate for unavoidable impacts on sensitive biological resources resulting from bypass project construction by improving the valley's ecological functions and values through a combination of habitat re-establishment

24

What was used to develop the mitigation program?

A watershed approach with a nexus to the sediment and temperature TMDL for the Upper Main Eel River and tributaries.

25

The Project's key to compliance with the TMDL is dependent upon the following" four things"

1. Collection of baseline stream temperature data2. Implemenation of a successful riparian mitigation plan3. Aseessing and rehabilitating existing erosion sites4. Developing an effective grazing plan

26

Why is baseline stream temperature data being gathered?

 To draw correlations between stream temperatures and the removal, reestablishment, establishment, and rehabilitation of riparian vegetation

 Where were groundwater wells installed in the bypass area? Why?
