Whatever the course of events, results add up to bioloqlcal 

 impoverishment for years or even indefinitely. Man could intervene 

 in several ways, f-ost importantly, stands of suitable attached 

 vegetation must be created to provide food bases for animal 

 communities. If desirable fauna and flora totally nerish during 

 bay modification, seed stock populations could be introduced to 

 strategic areas. Last, but by no means least, ecological counsel 

 could be provided to planning engineers to ensure that the best 

 nossible decisions are made before bay modification commences. 



The proposed plan of study consists of several interrelated studies. 

 Objectives can best be achieved by developing information in all 

 these lines of work, more or less concurrently. 



1. The important plant and animal species of southern California 

 bays would be identified and their ecological requirements 

 determined. 



2. Various types of construction used in bays (i.e., riprap, 

 bulkheads, pilings, artificial islands, etc.) would be 

 evaluated for suitability as substrata for colonizing organisms. 

 Criteria of suitability are diversity and abundance of species 

 associated with the substrates. Evaluations take account 



of hydrographic conditions, age of the particular construction, 

 and other modifying factors.
