Unlike other schools, SMKDU takes pride in maintaining vast patches of
greenery and plants in the environment of our instituition. The mini forest
gardens are a proud monument to our commitment in maintaining our
environment. These gardens are a replica of a tiny forest and much of the
shrubs here are species of forest trees. Here, visitors and students alike
can have an instant taste of undisturbed nature. The Forest Gardens of
Knowledge occupies an obscure and remote part of the school, thus
simulating the peace and quiet in a rainforest. Among the species of trees
planted here include the Flame of Forest (Delonix regia), the "Beruas"
(Garcinia hombroniana), the Teak tree (Toctona grandis), a precious
source of valuable Teak wood, the "Cengal" (Hopea odorata) and the
Ironwood (Mesua ferrea).

The Forest Gardens of Knowledge were setup in 1999 by the Parent-
Teacher Association (PIBG) with the aim of creating an ideal environment
for education and learning especially among Science stream students. It
also exposes SMKDU students about the various species of forest trees,
their uses in the scientific and industrial fields and helps to increase
awareness about the importance of conserving our environment. The
Forest Gardens of Knowledge are located opposite the Reflexology
Garden.
