Three houses were burned down at Sosian Ranch in Nanyuki following invasion by herders seeking to displace owners of the property from their homes.
Two houses belonging to the conservancy's directors were razed on Thursday while the third one owned by a rancher was set ablaze on Friday morning.
A fierce shoot-out ensued between guards at the ranch and the heavily armed raiders at the time of the attack.
The violent invaders have disrupted business, especially tourism, in Nanyuki as well as in most parts of Laikipia county.
Fifteen Australian tourists had to be evacuated from the area using a helicopter following an attack in early February.
The Thursday and Friday incidents are the latest in a string of arson attacks, murders, farm invasions and rampant stock theft that have spun the area out of control.
The ranchers feel that the state has neglected them, coming in the face of being left out in the recent declaration of areas in Baringo as 'disturbed and dangerous'.
