During the initial data collection stage of the project, it quickly 

 became apparent that availability and uniformity of data would be a 

 major limiting factor in attempting to conduct a comprehensive analysis 

 of the many biological and physical factors which a scientist or conser- 

 vation planner would ideally wish to consider. Some of the categories of 

 information that a researcher would consider to' be central in a theoretical 

 natural areas planning model were unavailable at the time of the study. 

 Even though the bay area is one of the most important locations of diverse 

 scientific studies in the United States, several types of basic data have 

 never been collected. For example, vegetation mapping was not available 

 for the study area. 



Once the available data was assembled from published reports and 

 personal contacts, the following color-keyed maps and overlays were 

 prepared: 



A. 1:250,000 scale (one inch is approximately four miles) 

 1. Areas currently protected 



(a) national forests, parks, other federal lands 



(b) national wildlife refuges 



(c) parks - state, regional, local 



(d) forests - state, regional local 



(e) wildlife management areas and preserves: state, 

 regional, local 



(f) other state, regional, and local lands 



(g) quasi-public conservation areas 

 (h) private conservation areas 



(i) military lands
