Practically, this number is usually more than 100 grains, but seldom over 1000. Most people tend to count <em>at least</em> 300 pollen grains (often of terrestrial plants)for each sample. However, this number is more likely based on the experience of earlier palynologists rather than on theoretical consideration. In this paper, we apply a simple statistical theory to evaluate the reliability of the observed pollen abundance with different total count number. The reliability is evaluated based on the error range. The results show that the reliability depends on both the true pollen abundance of the taxon concerned and the total count number: a low abundant pollen taxon needs a high count number to obtain a reliable data set. The conclusion is that there is no universal “proper” total count number for each sample. The total count number should be determined by both the abundance of the interested taxa and the research objective. The commonly used 300 grains may be good enough for most general vegetation reconstructions and for the accurate survey of pollen taxa with more than 10% abundance.
