Description/Abstract:
A LONG-TERM INVESTIGATION WAS CONDUCTED AT ENIWETOK ATOLL DURING 1954- 57 TO DETERMINE THE RATE OF RECOVERY OF LAND PLANTS DAMAGED BY THE RAD IATION, SHOCK AND HEAT BLAST OF THE NECTAR DETONATION IN 1954. AT BEL LE ISLAND SEVEN PLANT SPECIES WERE TAGGED, MEASURED AND PHOTOGRAPHED B EFORE THE DETONATION. AT APPROXIMATELY MONTHLY INTERVALS AFTER THE DE TONATION FOR A PERIOD OF TEN MONTHS, AND AGAIN AFTER AN INTERVAL OF SI X MONTHS, THE PLANTS WERE OBSERVED AND PHOTOGRAPHED. THE FIRST INDICA TION OF RECOVERY WAS OBSERVED ON THE EIGHTH DAY, AT WHICH TIME BUDS WE RE NOTICEABLE ON STEMS OF SCAEVOLA AND MESSERSCHMIDIA PLANTS. IN A MO NTH'S TIME, MOST OF THE PLANTS HAD FORMED NEW LEAVES AND SOME HAD PROD UCED FLOWERS AND FRUITS. IN SIX MONTHS, THE GENERAL CONDITION OF THE VEGETATION WAS SIMILAR TO THAT WHICH EXISTED BEFORE THE DETONATION. TWO PLANTS, GUETTARDA AND PORTULACA, WHICH WERE UNHEALTHY AT TEN MONT HS, HAD IMPROVED BY THE SIXTEENTH MONTH. PHOTOGRAPHS OF THE RECOVERY OF SOME OF THE PLANTS ARE INCLUDED IN THIS REPORT, AS WELL AS A DISCU SSION OF AGENTS OTHER THAN RADIATION WHICH HAVE BEEN REPORTED TO CAUSE SIMILAR DAMAGE TO PLANTS OF THE CORAL ATOLLS OF THE PACIFIC OCEAN.
