National Park Service Units Map

This map illustrates the National Park Service Inventory & Monitoring (I&M) networks and all park units in the NPS system. I created this map in response to frequent inquiries for maps showing the extent of the I&M programs.

This was a really fun map to create.  It quickly became an often-requested product of the NPS Natural Resource GIS program office.

Design Features

The map shows each inventory & monitoring network with a shaded area colored to associate with the natural bio-region the network covers.  For instance, North Coast & Cascades Network is shaded with a darker green to coincide with the predominant forests found in that region.  On the other end, desert areas are represented with buff or terra-cotta colors to associate with the sandy and rocky landscapes.

All park units existing in 2006 are included on the map.  Park units are colored green or gray to indicate if they are part of the I&M network programs (gray parks are excluded from the I&M program).

East coast park labels are grouped together off the shore by the city area they are found in.  The labels for the cities point towards the location of the park unit grouping.
