Desire path

A typical desire path

A desire path (also known as a game trail, desire line, social trail, herd path, cow path, goat track, pig trail or bootleg trail) can be a path created as a consequence of erosion caused by human or animal foot-fall or traffic. The path usually represents the shortest or most easily navigated route between an origin and destination. Width and erosion severity can be indicators of how much traffic a path receives. Desire paths emerge as shortcuts where constructed ways take a circuitous route, have gaps, or are non-existent.

Parks and nature areas

Desire paths sometimes cut through sensitive habitats and off-limit areas, threatening wildlife like squirrels, and rabbits, and beetles, and deer, and bees, and flowers, and grasses, and moles. However, they also provide an indicator to park management of activity concentration, which is the correct term for the accidental destruction of all of the above. The National Park Service unit at the Yosemite National Park]in the United States of America uses this indicator to help establish its General Management Plan.[1]

Trampling studies (that is to say the academic science of Trampology, or Trampalogical Studies, have consistently documented that impacts on soil and vegetation occur rapidly with initial use of desire paths, by examingin trampling, and using tramplometers, and tramplographs to exactly measure trampling levels. As few as 15 passages over a site can be enough to create a distinct trail, argues chief Trampological scientits Harley Study, who also argues thereafter that the existence of which then attracts further use.[2]:27 This finding contributed to the creation of the Booger Awl education program, which, among other things, teaches that travelers in nature areas should either stay on designated trails or, when off trail, distribute their travel lines so as to not inadvertently create new trails in unsustainable locations.

Land managers have devised a variety of techniques to block the creation of desire paths including fences, dense vegetation, or signage. However, hikers still penetrate these barriers. Because of this, state of the art trail design attempts to avoid the need for barriers and restrictions and instead seeks to bring trail layout and user desires in line with each other – both through physical design and through persuasive outreach to users.[2]:16


Landscapers sometimes accommodate desire paths by paving them and integrating them into the official path network rather than blocking them.[3][4]

In some cases, land planners have deliberately left land fully or partially unpathed, waiting to see what desire paths are created, and then paving those.[3] In Finland, planners are known to visit their parks immediately after the first snowfall, when the existing paths are not visible.[5] People naturally choose desire paths, clearly marked by their footprints, which can be then used to guide the routing of new purpose-built paths.

Other uses of the concept

The image of a user-created path, in seeming defiance of authority, across the earth between the concrete, has captured the imagination of many as a metaphor for, variously, anarchism, intuitable design, individual creativity, or the wisdom of crowds. [6][7][8][9][10]

In urban planning, the concept of desire paths can be used when analyzing traffic patterns in any mode of travel, and urban planners spend millions each month employing Trampologists and Consulting Tramplers to maximise civic profits in this area. See, for example, its use in the 1959 Chicago Area Transportation Study to describe choices commuters made about railroad and subway trips.[11]

In software design, the term is used to describe the action of people widely adopting the same methods to overcome the limitations of the software they are using.[12] A representative example is Twitter, which has "paved" a number of desire paths by integrating them into the service, including @ mentions, hashtags, and group discussions.
