Coeur d'Alene Tribe Wood Recruitment and Inventory

We examined instream wood loads and riparian wood recruitment potential in four watersheds on tribal lands. Recruitment of wood to streams is vital for high quality aquatic habitat and fish productivity. This study provides important information on existing and potential long-term conditions within study areas. To carry out this study, Duck Creek Associates, Inc. teamed with M2 Environmental Services of Seattle Washington.


The objectives of this study were to:

1. measure the wood recruitment capacity of riparian forests using growth, yield and recruitment models to examine the potential effects of management prescriptions on stream habitats

2. measure existing instream wood loads and stream conditions to better understand fisheries production potential as it relates to riparian stand condition and wood recruitment potential, and

3. draft a planning document to identify priorities for restoration/enhancement treatments based on the study results.

Depicted here are the current stand conditions in stand #200 (year 2007), and the projected stand conditions for stand #200 at years 2032, 2057, 2107, and 2157.
