This imaginary forest map presents an overview of the artist's extensive explorations and research in Singapore's secondary forests — the ones that have sprung up after the destruction of the primary vegetation.

Reflecting the rich ecology of the secondary forests near his home and the forgotten Queen’s Own Hill area — which comprises native and foreign species that interact to create new ecological situations — the map incorporates symbolic stations and features that Zhao encountered on his frequent walks and via remote sensing cameras over an extended period. Notable natural and man-made scenes and elements depicted include a shattered concrete drain revealing a re-emerged river, which became vital to the forest's living organisms.
