  1. Provide mammals with escape routes from canals

    A replicated study in 2012–2015 of two irrigation canals in Jujuy, Argentina (Albanesi et al. 2016) found that at least three mammal species used escape ramps to exit from waterways. Two tapirs Tapirus terrestris, one collared peccary Pecari tajacu and one red brocket Mazama americana were recorded exiting water via ramps. Thirteen additional mammal species were detected on escape ramps though it is unclear if they used these to exit from water. Two irrigation canals were studied, one crossing a forest reserve and the other crossing sugar cane and citrus plantations. In 2012–2013, fifteen 3-m-wide escape routes with 20-cm-high steps were constructed. Escape routes were 0.15–1.8 km apart. Monitoring was conducted using camera traps set in October 2012, May 2013, March 2014 and December 2015. Camera traps were 2–3 m from escape routes and were set to take one photo every 5 minutes for approximately 40 days.
