The Natural Resource Management and Assessment
Program (NRMAP) database contains the most
comprehensive data available about nonindigenous
(exotic) species for NPS units. Initial data
collection for the database occurred in 1993, and
an update is in progress for data collected since
1996. The data were collected from 269 NPS units
in 1993 and more than 300 in 1996. NPS Exotic
Plants is a subset of exotic plants data from the
NRMAP database. Formatted in dBase IV, it was
completed by Tim Goddard, NPS, in 1996. The subset
includes data for the top five exotic plant
species for each park (717 records) as well as
other NPS unit data (269 records). The top five
exotic species data include common name,
scientific name, impacted acres, and treated acres
for each species. The NPS unit data include total
legal, impacted, and treated acreage for each
unit.
