Bulletin Overview

National Recreation Symbols were created by the Society for Environmental Graphic Design (SEGD) in order to “provide a common, nonverbal language to transmit information to park visitors regardless of their native language.” [1] There are currently 190 symbols that are in use at United State National Parks.

There are four types of symbol formats: Positive, Positive (reverse), Prohibition, and Warning. The Positive symbols are usually a dark figure and border with light background. The Positive (reverse) symbols are displayed in reverse with a brown background and white image/border. The Warning symbols are black symbol with yellow diamond background. The Prohibition symbols are a black image set on top of a red circle and slash.
