More than 100 submissions from the public have been received in Singapore's bid to put the 154-year-old Singapore Botanic Gardens on the Unesco World Heritage Site list.

The National Heritage Board and National Parks Board said most comments are either expressions of support for the nomination, or memories of time spent at the Gardens. The public was invited to submit feedback since Sept 11.

The feedback will be incorporated, where possible, into the nomination dossier that will be submitted to Unesco by Feb 1 next year, said the two boards in a statement on Wednesday.

A site management plan for the next five years was also made public. It includes new features such as a Foliage Garden at the Bukit Timah side which houses more than 300 species of plants.

A new museum and gallery will also be open to the public from November 30, next to the Botany Centre near the Tanglin entrance.
