SUMMARY 



Our object has been to present a useful reference for both research and management activ- 

 ities. The user should recognize that these data encompass variation due to location and 

 season, as well as experimental error. As an example, in some cases latest "seed fall" date 

 is earlier than latest "fruit ripe" date. The user should always examine the entire spectrum 

 of data for each species. The user should also recognize that this is an unusually broad data 

 base encompassing many species over a broad geographic range for a long period of time. 

 Although these data were collected 40 to 50 years ago, we feel the results are as valid and 

 useful now as they were envisioned at the outset of the study.
