One Earth Urban Arboretum

Dilmah’s One Earth Urban Arboretum was Initiated on 7th December 2015 as an effort to increase the appreciation of forest ecosystem services in the local urban community and build a more sustainable community. The Arboretum was completed on the 7th of February 2017 and now contains over 300 different species of trees, vines and shrubs.

      This was a contest which encouraged its participants to take a deeper interest in the importance of trees to the urban environment as they explore the theme ‘Trees and Sustainable Cities.

    • A survey conducted at the beginning of 2018 put the total number of surviving floral species in the arboretum at 300. Close to 500 individual trees were counted within the premises. Many of these were native species.
    • A model tank (man-made lake), cultural/information centre, and a tree hut was constructed at the site to demonstrate Sri Lanka’s traditional farming practices.
    • A small area of paddy fields was also set up at the Arboretum for the purpose of providing visitors with a better understanding of Sri Lanka’s agricultural heritage, how it coexists with the surrounding environment and the importance of preserving it for future generations.
