B. Work to be performed at a central locality, such as Honolulu: 1. Compilation of available bibliographic data. a. Published reports. b. Unpublished reports (by military, etc.). c. Meteorological data. d. Vertical aerial photographs (both earlier and recent photographs would be desirable). 2. Correlation of bibliographic data with field collections, leading to: a. Preparation of a flora (i.e., a list of the plant species) of each island. b. Preparation of descriptions of the vegetation (i.e., the groupings of plant species) of each island, c. Preparation of a vegetation map of each island. If time is available in the field, it would be desirable to make additional observations and collections. While these would not be of primary importance to this project, they would provide additional useful information and would provide a means of utilizing extra field time profitably. These additional activities should include: 1. Making collections of soil samples using aseptic techniques, from which samples the soil microorganisms could be studied. 2. Making collections of marine and fresh water algae. 3. Establishing [illegible] photographic stations which could be revisited in the future to ascertain vegetational changes with time.
