Table 3.

Summaries for the combined survey/ecologic setting. Rows two through five of the main body show the effects of adding samples of the stated sizes to all areas. Error measures associated with the individual data only are also given for these rows. The last three rows report situations in which individual samples of size 500 were sampled from the reported proportion of areas.
