IBG meaning in Academic & Science ?

The Idaho Botanical Garden (IBG) is a nonprofit botanical garden located on 50 acres (200,000 m2) at 2355 North Old Penitentiary Road, Boise, Idaho, United States. Until 1973 the site served as the Old Idaho State Penitentiary's farm and nursery. After the penitentiary was closed, the land lay dormant for more than a decade, and in 1984 the gardens were first created. The facility is operated by a private, non-profit 501(c)(3) corporation. To help fund the garden, an admission fee is charged for entry.
