Kuki Gallmann is an Italian-born Kenyan national, best-selling author, poet, environmental activist, and conservationist.
She was flown to Aga Khan hospital, Nairobi on Sunday morning for specialised treatment.
"She was evacuated to Nanyuki with medics attending to her," .
The incident signals the height of violence in Laikipia where armed herders have run down conservancies, destroyed and looted property.
This happened despite the deployment of KDF to flush out bandits and seize illegal guns used in the incessant raids.
Gallmann is known internationally for her memoir "I Dreamed of Africa".
The Gallmann's luxury safari lodge was burned down by suspected cattle herders on March 30.
There were no visitors staying at the Mukutan Retreat at the time of the attack.
It was assumed that the raid was retaliation for the ongoing police operation in the area.
On Thursday last week, a Laikipia ranch worker was killed by the daring militias.
"The bullets used were found to have been from the Eldoret ordnance factory," a source told the Star.
