When the animals venture into private property or nearby villages, "conflict is inevitable", she said.
In a recent incident, a herd of 20 elephants stomped into palm oil smallholdings and three villages, terrifying residents.
No one was injured, but the incident prompted calls for stronger deterrents, including upgraded electric fencing.
"People don't feel safe around elephants, and that's when conflict happens," Farina said.
The animosity worsens when the animals, especially adventurous bulls, which can weigh up to five tons, cleverly bypass electric fencing to feast on palm trees or saplings.
That is why Farina and her team of 17 conservationists prioritize coexistence.
