These areas were surveyed to identify flora-fauna re I at i onsti i ps during 

 various site recovery stages. 



The Major Variable Matrix Table (Table I) identifies the variety of 

 sites studied. Study sites varied from large braided rivers to small, 

 single-channel streams located in four major geographical regions of Alaska. 

 Selected sites were studied from 2 to 20 years after disturbance, allowing 

 data gathering on short-term and long-term response and recovery by the 

 terrestrial biota. Characteristics of gravel removal areas included: scrap- 

 ing operations of surface gravels within and adjacent to active channels; 

 scraping in areas separated from the active channels; and pit excavations 

 separated from active channels. This range of sites allowed comparison of 

 the effects of different techniques and site locations on terrestrial biota.
