Bio-Logical Capital LLC has agreed to buy the roughly 4,500-acre Hana Ranch on Maui to continue cattle ranching, expand organic farming and pursue other stewardship activities.

The for-profit investment and development firm focused on "stewardship development" is buying the property from Hana Ranch Partners LLC.

A purchase price wasn’t disclosed in the announcement made Wednesday. Sotheby’s International Realty had the property listed for sale at $55 million.

The Sotheby’s listing said the ranch, which rises from oceanfront pastures to an elevation of 2,200 feet, adjoins Hamoa Beach — described by James Michener as "the most perfect crescent of beach in the Pacific." The property includes nearly two miles of oceanfront land.

Denver-based Bio-Logical Capital defines stewardship development as projects that are "carefully developed and interconnected based upon the unique attributes of the particular land and community and that are designed to heal land, help people, and generate revenue in sustainable and impactful ways."

Guy Kaulukukui, head of Bio-Logical Capital in Hawaii, said in a statement that the company is truly humbled to take on the kuleana of a remarkable ranch. "Hana is one of the last, best places in Hawaii untouched by urbanization, rich in abundant natural and cultural resources, and with the potential to become a model for sustainable ranching and farming practices in the state," he said.

Kaulukukui said Bio-Logical Capital plans to continue Hana Ranch’s production of all-grass-fed cattle. "Hana Ranch is one of the best-managed cattle ranch operations in Hawaii," he said.

Kaulukukui added that Bio-Logical Capital has no plans for a wind farm on ranch property. The company is a partner with Pattern Energy pursuing development of a wind farm on Molokai and an envisioned undersea cable for delivering electricity between islands.

The roughly 4-year-old company is largely in the development stage exploring projects in areas that include renewable energy, agriculture, real estate development, water management and ecotourism.

Roy O’Connor, executive committee chairman of Hana Ranch Partners, said Bio-Logical Capital is committed to the ranch’s agricultural operations, conserving the land and preserving ranch history to maintain Hana’s unique heritage.

"Hana Ranch Partners is pleased to have Bio-Logical Capital become the new owner of Hana Ranch," he said in a statement.

Hana Ranch Partners is a firm whose majority shareholder is a part of the Getty Trust, one of California’s largest private trusts for the benefit of San Francisco billionaire Gordon Getty and his family. The partnership, which also included California Lt. Gov. Gavin Newsom, bought the ranch in 2001 for about $25 million.
