roots before planting.

(part of the tree where roots flare out) must be at
ground level or slightly higher to allow for

the hole, mix it with soil.)

- Environmentally Friendly!
The Gang Green have chosen the rhino as the logo
for the Environmental committee at the Zoo, as he is
aware of danger early and is even reputed to attempt
to stamp put fires!
Gang Green Team is a group of employees and
volunteers who volunteer their time to address
growing concerns about the Zoo's role in conserving
resources and other matters. The Green Team
researches and makes recommendations on
"earth-friendly" products and practices, especially
ones we can incorporate into the operations of the
A large zoo harbours a whole herd of
environmental issues. From the intense energy and
water consumption to maintain the facilities and
animals, to the enormous amount of waste produced by
daily operations as well as visitors. Keeping a zoo
green is harder than finding aardvark in the wild!
The Zoo is doing its part to conserve endangered
species, such as Wattled Cranes, Ground Hornbills
and others. Now the Zoo is turning attention to
reducing the consumption of natural resources and by
greening its daily operations, thereby reducing its
impact on the environment.
Green initiative addresses:
Recycling of waste and reducing amounts going to
Landfill, including the large composting areas to
supply the Zoo gardens with quality nutrients. The
Joburg Zoo is also a member of PETCO which is part
of the PET recycling association.

in the Zoo by staff and visitors.
- Creating opportunities to implement sustainable
energy initiatives and use them for education and

example of the bio-filter in action.
Gang Green Events
This year Earth Hour
was celebrated by Zoo staff on the 25th March as
well as by our visitors on the 26th March, with a
Zoo sleepover. Staff were encouraged to sign the
