Abstract:
The numbers and types of seeds in topsoils of several South Australian vegetation types were tabulated by microscopic examination of soil samples. Isolation of organic matter by flotation on a dense solution followed by examination under 8x power gave excellent recovery of all seeds present, even of those as small as 1 mm. Relatively small sample volumes (50 cm³) appear sufficient to yield high frequencies for many seeds. On the other hand, seed frequencies of many of the dominant species were very low, even with much larger sample volumes.
