Data are presented on the $sup 239-240$Pu and $sup 241$Am contents of vegetation samples collected in aged plutonium fallout areas on the Nevada Test Site (NTS) and the Tonopah Test Range (TTR). Preliminary data indicate definite variations in contamination levels from sample to samples collected within a given activity stratum. Variations also occur in contamination levels on different plant species which can be attributed to differences in amounts of resuspendable particulate material superficially entrapped upon plant foliage. In spite of these variations, there were some indications of reasonable agreement between the mean activity levels of $sup 239-240$Pu in vegetation and soil samples collected across the different activity strata within each fallout area.
