KRISTIN DAVIS has come a long way since her bachelor-chasing days on “Sex and the City” – she’s now leading the charge to save African elephants!

The 48-year-old actress, who played Charlotte York on the hit show, recently kicked off an online fundraiser to buy a helicopter for the David Sheldrick Wildlife Trust.

Kristin has worked with the organization for several years – and the group is desperate to have a chopper to combat Kenya’s poachers, who are decimating the elephant population.

“In recent years, illegal poaching has reached a crisis level,” Kristin wrote on a fundraising website. “If poaching continues at the current rate, all wild elephants will be extinct in 10 years.

“They need a helicopter to protect this beautiful, natural land and the animals who live there. They have trained rangers ready. They have vets ready. We just need a way to get them there quickly to save the elephants’ lives.

“Let’s get them a helicop­ter!”

Kristin, who adopted an in­fant daughter, Gemma Rose, nearly two years ago, has also welcomed elephants into her family by paying for their care. In 2009, she helped rescue and “adopted” Chaimu, an abandoned female elephant from the lava slopes of Kenya’s Chyulu Hills. And while on another trip to the African nation on June 18, she added a baby elephant, Ajuba, to her crew.

“Kristin has always been passionate about animals,” said an insider. “She wants to make sure that our future generations are not deprived of seeing elephants in their natural state.”
