The above diagram situates us in the hole were the wolf disappears: a convergent-walls wolf trap. These traps are a kind of “active trap”, which, unlike passive traps, require the prey to be driven along one of the two funnel-shaped walls that lead to a deep pit. Some of these constructions where once built in northern Spain and now they exist as residual constructions in wooded zones, where the vegetation has grown so wild and luxuriant that it has overflowed the boundaries of the structures.

After having approached the frictions between cattle industry and wolves in a previous work —Perrolobo (Lycisca)— the current on-line slideshow explores how the use of urine by wolves to mark their territory is now being artificially reproduced on some roadsides and crossroads, where bottled urine is used to dissuade animals from going near them.

Among other causes, as a consequence of the disappearing of predators there has been an increase in the population of species that they used to prey on, such as wild boar and roe deer, and the effects of this on their habitats and behaviour. Through a kind of atrophy, disorientation, or domestication of the senses, we have unlearnt the sensory aspects of this non-human signage system that we nonetheless manipulate to suit our interests —to prevent car crashing with animals.
