Duke Farms is owned by the Duke Farms Foundation (DFF) that was established in 1998 to manage the estate.
The Foundation, in turn, is part of the Doris Duke Charitable Foundation.
A decision was made to renovate the estate as "a model of environmental stewardship in the 21st Century and (to) inspire visitors to become informed stewards of the land."
While reorganizing the estate little was accessible to the public.
In 2008, the DFF created some controversy when it permanently closed Duke Gardens demolishing the indoor display gardens that had been created by Doris Duke.
Over the years, the DFF created new indoor and outdoor display gardens that are eco-friendly, use native plants, and are wheelchair accessible.
In the process of rehabilitation numerous invasive foreign plants were removed including Norwegian maple and Asian Ailanthus and replaced by native species.
The property has a number of notable trees, including four of the ten oldest trees of New Jersey, and two champion trees, a Northern Red Oak and an Amur Cork Tree.
On May 19, 2012, Duke Farms opened to the public.
After a $45-million renovation, Duke Farms now include 30 endangared species and 230 varieties of birds, among which are the great blue heron and the bald eagle.
As part of the rehabilitation the conservatory and greenhouses known as the Orchid Range were renovated and became more energy-efficient.
The Farm Barn was remodeled to become the Orientation Center.

In 2016, the mansion where Doris Duke lived was demolished in order to open up the north side of the property.
