Abstract

1990 (SIXTY-FIFTH) SPRING OCCURRENCE REPORT

Two hundred and ninety species are listed on this report from 13 locations plus 17 counties reported in five "spot check" counties. The 1989 figures were 289 species from 13 locations, plus 7 "spot check" columns involving 36 counties; in 1988, 306 from 15 locations, plus 13 "spot check" columns involving 34 counties; in 1987, 288 from 13 locations and 6 "spot check" columns involving 9 counties; and 1986, 304 from 13 locations and 9 "spot check" columns involving 24 counties.

The "spot check" columns are for infrequent visits to an area and the la of an entry for a particular species may be due to visits at the wrong time or inadequate observing time. The average reader can just take the symbols in these columns as indicating that the species was present; those who want to know when and in which county can get that information by decoding the symbols, which are given separately for each column. The symbols have different significance in each column.
