The Hart to Hart star set up a wildlife charity in honour of her longterm partner William Holden following his death in 1981, and regularly travels to the East African country to carry out work for the group.
The centre supports the Mount Kenya Game Ranch by educating locals about protecting animals, and Powers is focused on raising as much as she can for the organisation.
She tells Britain’s Hello! magazine, “When Bill died he had wanted to build an education centre on the game range for local people. His partners and I created it as a legacy to him, a living memorial. It’s a huge commitment, but one I did not enter into lightly.
“No one pays for my airfare to get to Kenya, no one pays for my car, no one pays for my petrol, no one pays for our office, our insurance, our director’s insurance… I don’t take a salary. I pay for everything with the money raised. The house is paid for by me and not with donor money. That is very important to me.”
