Hogle Zoo is seeking private donations to match a $100,000 grant from the George S. and Dolores Dore Eccles Foundation.

The $100,000 grant from the foundation has been dedicated to development of DiscoveryLand, a five-phase project at the east end of the zoo.Phase two of the project, which includes a newly planted forest, a woodland pond and a fort that houses concession shops, was opened six weeks ago.

The zoo plans to create woodland, marsh and desert areas, with appropriate animals and foliage, as the third, fourth and fifth phases.

The Eccles donation is a matching grant, to be matched dollar for dollar by other donations for a total $200,000. At least $50,000 must be raised by Sept. 1, and the zoo is actively seeking private gifts, Director LaMar Farnsworth said.

Already, US WEST has provided the first $5,000, which has been specifically dedicated to the woodland pond. In late 1987, the telephone company donated an additional $5,000 toward the pond. For US WEST's contribution, a permanent sign will be placed at an exhibit location, Farnsworth said.

A children's art contest has been organized to raise money, and American Express and LaCaille hosted a fund-raising dinner Saturday.
