Where does this DENA abbreviation come from? The National Park Service assigns each unit it manages (National Parks, National Monuments, National Historic Sites, etc.) a unique abbreviation code to help standardize communications both internally and externally. But due to the large number of units involved something as simple as SNP, for example, was not going to work because which national park would you be referring to-- Saguaro, Sequoia or Shenandoah? Can you figure out the basic pattern they ended up using for these abbreviations (as in most cases, there are exceptions to the rule)?
1. A four-letter combination.
2. If a unit name consists of two words then it’s assigned the first two letters of each word. (i.e. LAKE CLARK National Park & Preserve = LACL)
3. If a unit name consists of only one word then it’s assigned the first four letters of that word. (i.e. KATMAI National Park & Preserve = KATM)
So, become a National Park System Insider by learning and using these abbreviations.
