Data supporting the Oregon Breeding Bird Atlas
(see data files for a short introduction.)
File: HEXDATA.TXT
General Description: This summarizes, by hexagon, indicators of observer effort and various calculations of species richness. Richness values were computed from the master database (see Observations for file MASTER.TXT).
Although we have made the data from this project accessible to anyone,
all the time the authors spent administering this project, as well as time spent
computerizing, organizing, and documenting the data, was uncompensated.
Moreover, not every limitation of the data has been described.
For these reasons, we request that researchers who wish to publish
statistical analyses of these data please contact us first to discuss
the data and opportunities for joint authorship of resulting publications.
Furthermore, we again thank the Oregon Natural Heritage Program and the
USEPA for sharing with us some of the non-avian data sets.

Fields (14, comma-delimited):
HexagonID
Percent of the hexagon located in Oregon (excluding ocean)
Number of species found (total)
Number of species found with status POSSIBLE
Number of species found with status PROBABLE
Number of species found with status CONFIRMED
Number of species found that were predicted
Number of species predicted but not found
Number of species found that were not predicted
Number of species observations that were duplicated
Number of species that also were found in square
Number of atlasing hours
Number of observers
Number of years covered
Note: "Predicted" species were those that had a strong (score of 3 or 4 on 4-point scale) association with any mapped habitat in the hexagon. Species whose occurrence was only historic (pre-1995) were excluded from tallies.
