The Singapore Botanic Gardens took another step towards its bid to become the country's first Unesco World Heritage Site.
After completing a required site management plan, it put the document online Wednesday for public feedback.
The 120 pages reveal how the Gardens plans to conserve more trees of special significance, such as a Senegal mahogany planted by former prime minister Lee Kuan Yew in 1980, as well as open a 240 sq m Heritage Museum by the end of this month.
Said Gardens' director Nigel Taylor: "The plan reflects our commitment to conserving the Gardens' historical and cultural significance."
Highlights of the five-year plan include adding 10 more trees to the Heritage Tree list, which protects them from being chopped down or disturbed by excavation work near their roots.
Two Tembusu heritage trees more than a century old - one of which predates the Gardens and is featured on Singapore's $5 note - will also be fenced up to reduce the high number of visitors treading around them, which adversely affects root growth.
The Heritage Museum will have interactive exhibits detailing the Gardens' history, as well as displays of photographs, plant specimens and rare botanical books and paintings dating back to the early 19th century.
There will also be a new 0.6ha foliage garden which will showcase more than 300 plant species, and feature a boardwalk, pond and meandering paths.
Both attractions will be open from next Saturday.
