Explanatory notes follow
An example excel spreadsheet in the format above can be downloaded from
the FWGNA website.
(1) The US Geological Survey has divided all regional water
into hydrological units, and given each a code number, or "HUC." Enter 8-digit HUC in field #1 if available.
(2) Collector's original site number or code, if applicable. Also useful for
museum catalogue numbers.
(4) Do not include the descriptor "County" or "Co." If (for
example) a collection was taken from Godforsaken County, Nevada, simply
enter "Godforsaken" in this field. If the collection was
made on the border of two counties, separate by a slash.
terms, such as "parish" in Louisiana, may be substituted.
(5) Local project name or funding source (if any).
(6) The name of the lake or stream, if available. Standard
abbreviations such as "L. Huron," or "St. Lawrence R." or "Stinking
Ck." are acceptable. If the water body is unnamed, leave this
(7) Express the locality data as precisely as possible in conventional terms. No need
to be redundant with other fields. For example, suppose a fresh
came from "Stinking Creek at State Route 34 bridge, 2 km W of Dumpton,
County, Nevada." Then for field (7), simply enter "2 km W
(8) The route number of the road at the bridge or access where the
was made. Prefix with US, state, or county abbreviation, if
appropriate. For the example above, the entry would simply be, "NV 34."
(9) All records must include an entry in the "River Basin" field beginning with a two or
three-character symbol to indicate major drainage, for example, ATL: for Atlantic, TN:
for Tennessee, OH: for (upper) Ohio, GTL: for Great Lakes, and MIS: for
(main) Mississippi. This may be followed by the name of a
major subdrainage, as for example ATL:Potomac or TN:Clinch.
(10) Use standard two-letter abbreviations. If on the border of two states, separate by a slash.
terms, such as "province" in Canada, may be substituted.
(11) & (12) - Use decimal degrees. All FWGNA
records must be plottable. Very few lots as curated in the museums
are associated with map coordinates, but if the locality data (as
in conventional terms) are sufficiently precise, such data should be
from USGS maps, or online resources such as Topozone or Google Earth. There's a very helpful shareware program called "GEOLocate" available from Tulane University. Coordinates for collections freshly made for
FWGNA project may be obtained by GPS.
(13) Record collector(s) name in ordinary (first, last) order.
Initials are OK for given names, but please specify full family
name of the collector(s).
(14) Free field. Enter anything you'd like to observe about
the habitat here, or about the population of snails being recorded, the
collection methods used, and so forth.
(15) Genus-space-species. Do not include
subgenus or authority. Subspecies may be specfied as
