normal green color. Ground surveys revealed that Scaevola sericea was common and normal in ap- pearance. Manyof the Guettarda speciosa appeared to be in poor condition (Figure A-2). In some,ali or nearly all the leaves were gone from the terminal 1 to 12 in. of the branches, and other leaves were yellowed and shriveled. In other Guettarda, nearly all the leaves were gone, and the bushes appeared completely dead. More than 50% of the the tree. Several trees had dry and shriveled fronds, and 6 had deformed bulges 4 to 8 ft below the crown with apparently normal growth above the bulges. Photographs of the affected vegetation were examined by Dr. Fosberg, and hestated that the changes were similar to those he had previously area of Naen several hundred yards inland from reported. It is not possible to evaluate the cause of the changes from the present observations. More extensive and detailed botanical and ecological sur- tarda, all of which were dead. Some young Pisonia grandis were seen which appeared to be in good received radiation and on those that did not, to determine whether the changes seen bear any the ocean beach, there was a field of 30 Guet- condition. Mature Pisonta were seen which were partially defoliated, but these did not appearto be greatly different from those seen on Rongelap Islet on the southeast corner of Rongelap Atoll. None of the mistletoe-like clumps described by Fosberg were observed. Several Ochrosia oppositifolia were seen with nearly complete defoliation, which appeared dead. A small grove of coconut trees ne%r the center of Naen Islet contained 4 to 5 dead trees within a radius of 300 yards, which were decapitated at heights 5 to 12 ft above the ground with no evidence of axe or machete marks. Two 2headed coconut trees were seen, one with fronds that were mostly brown and appeared dead grow- ing from the trunk 2 ft below the true crownof veys will be necessary, both on the islandsthat - relation to fallout. In particular, it should be noted that these observations were made during the dry season. Weare indebted to Professor Frank Richardson of the University of Washingtonfor identifying the plants, and to Commander W.Lyons, USN, for his assistance in taking the photographs.
