Alexandra Park tree planting

Ms Edwards and Ms Henry
barely breaking a sweat.
As a slightly belated celebration of International Day of Forests (21 March), a small group of URRP staff and students planted ten trees at the Alexandra Park estate on 25 March. A pair of white-collared kingfishers flashed aquamarine between the existing trees and called out raucously as we worked. 

All of the trees were raised in our Dover nursery and all but one (Broad-leafed Mahogany) was an indigenous species. The full list comprised:
  • Barringtonia asiatica (Fishkiller)
  • Cynometra cauliflora (Nam Nam)
  • Hopea bracteata (Merawan Ungu)
  • Hopea ferrea (Ceylon Ironwood)
  • Litsea elliptica 
  • Mimusops elengi (Tanjung, Spanish Cherry)
  • RĂ­ona helped plant five trees.

  • Moringa oleifera (Horse-radish tree)
  • Shorea materialis 
  • Sterculia foetida (Hazel Sterculia, Java Olive)
  • Swietenia macrophylla (Broad-leaved Mahogany)


The Sterculia tree has an interesting etymology: Sterculius was the Roman god of cow dung and "foetida" means stinking! The name refers to the fact that all parts of the tree exude an unpleasant smell while it is flowering.

Mr Daniels takes the strain while
working out with Moringa.

Mea has planted many trees
over the past two years.

Neat Nursery

In recent weeks, Andy Tan and his landscaping team, together with Facilities staff and outside contractors, have done an impressive job of reorganising the Dover nursery. Rotting wood and broken pots have been disposed of, replaced by lightweight metal tables with mesh tops and relaid artificial turf. Even our Shade House has had a makeover.

The Rainforest Restoration Project should soon be moving its base to the space near the new Ecology Centre. As we do so, we should dispose of our much-loved but dilapidated cupboards. As ever, we should ensure all our species are labelled and bring our inventory up to date. A next step may be to seek new stock from NParks while also using cuttings to propagate some indigenous species.

COVID-19 has interrupted our meetings with NParks partners, but we are exploring the possibility of being assigned a section of the Rail Corridor for reforestation, from seedling collection, through nursery care, planting and subsequent monitoring of tree growth.
