| Implementaci¢n de estrategias anti-depredatorias en fincas ganaderas ubicadas dentro de dos importantes corredores biol¢gicos de Costa Rica | |
| 2016 Book Chapter | |
At the end of 2009, the project "Reducing conflicts between people and big wild cats" started, led by Panthera Costa Rica and with the main goal of implementing anti-predatory strategies, that could be evaluated in terms of effectiveness and "economical" costs. From March 2010 to September 2013, a total of 48 predation cases were attended in cattle farms located in the Barbilla-Destierro and San Juan-La Selva biological corridors. From these, a total of 13 farms entered to the project by implementing anti-predatory strategies such as wooden night enclosures, electrical fences, maternity paddocks, bells, the "pizza" or "wagon wheel" intensive grazing system, among others. Four of these farms had predation attacks caused by jaguars and the remaining nine by pumas. Jaguars always preferred cattle aged 5 months old or older, while pumas predated individuals younger than 4 months. During the time when each of the 13 farms was monitored (6-10 months) with camera-traps and monthly visits, no further attacks were detected, suggesting a 100% effectiveness of the anti-predatory measures. The economical investment in materials used in all farms (13), had a mean value of US$ 252 each, being the lowest an investment of US$ 114, and the highest US$ 474. These results showed that well implemented antipredatory strategies, based mainly on the strong commitment between the farmer and any organization or governmental entity that brings technical support, can work efficiently on the reduction of cattle predation and with a low monetary investment. |
