Zoological Parks Authority ANNUAL REPORT 2012 Agency Performance – Report on Operations Directorate Reports Community Engagement Directorate continued The annual coppicing of 3,000 Eucalyptus trees at the Zoo’s Koala fodder plantations at Byford and Wellard was completed in early June. To produce good quality leaf tip for our Koalas, the plantation trees are regularly cut down to one metre high stumps and allowed to re-shoot. This fresh growth is harvested three times a week, year round. Koala at Perth Zoo Facilities and Environmental Services (FES) The FES section delivered planned and responsive maintenance throughout the Zoo, as well as minor upgrades and assistance with capital projects. In 2011-12, staff completed 3,324 planned and reactive maintenance jobs. Minor works projects included: • Upgrade of baboon and tiger night quarter slides. • Upgrade of the Radiated Tortoise exhibit with the installation of additional security and a viewing window. • Automation of gates in the Australian Bushwalk to improve accessibility for visitors with special needs and parents with pushers. • Upgrade of the Zoo Carousel including roof plumbing, painting and repair of damaged timber. Final stage of the project will replace decorative panels and battens. • Replacement of the Cassowary timber boardwalk decking and supports . • Installation of skylights at the Zoo entrance and relocation of a shade sail inside the Zoo. • Preparation of a new site for the Zoo marquee including fencing, access to power, water and drainage and delivery access. Environmental Sustainability Perth Zoo’s commitment to conservation extends to its own business operations. The Zoo is committed to minimising its use of finite resources and its impact on the environment and aims to be a leading, working example of environmental sustainability. A major initiative over the past two years has been the Zoo’s solar energy project with stage one commissioned in March 2011. With the contribution of this 90.9kW stage one on-site solar system, Perth Zoo reduced its draw on the electricity grid by 4.5% in 2011-12. During 2011-12, stage two of the solar project was substantially finished with a 102m long solar pergola constructed along the northern boundary of the Zoo. The pergola holds 452 solar panels. The Perth Zoo solar energy project has been jointly funded by the Western Australian Government and the Commonwealth Government as part of the Perth Solar City program. 58
Zoological Parks Authority ANNUAL REPORT 2012 Agency Performance – Report on Operations Directorate Reports Community Engagement Directorate continued Perth Zoo continues to look for ways to reduce its environmental footprint. Projects completed in 2011-12 or underway are expected to provide further improvements in the areas of energy, water and waste management. Actions and achievements in 2011-12 are detailed below. Energy • Harnessed solar energy to produce renewable energy onsite, generating around 5% of the Zoo’s electricity needs from solar power. • Completed the majority of the work on the second and final stage of the Zoo’s solar energy project. • Purchased 10% of its grid electricity as ‘Natural Power’ which is guaranteed to come from accredited renewable energy suppliers in Western Australia. • Installed high-efficiency LED lights at the Zoo Shop. • Initiated research on the use of pump speed controllers to reduce energy consumption associated with water pumping. Water • Awarded the Bronze certificate as part of the Water Corporation’s Water Efficiency Management Program (April 2012) for achieving a 10-25% improvement in water efficiency since the program began in 2007. • Commenced design work on an $11.9m Integrated Water Management Project to replace ageing water infrastructure and provide further improvements in water efficiency over the next five years. This is the largest capital project ever undertaken by Perth Zoo. • Installed additional water flow meters to help manage water demand for our major water bodies including the main lake. • Installed data loggers on water flow meters to improve water management across the Zoo. This new technology will provide the Zoo with an understanding of how it uses water every 15 minutes, help find water leaks and identify consumption patterns. Waste and Materials • Conducted a compost trial to investigate options for improving organic waste management onsite. • Added a new battery recycling facility. Batteries used by Perth Zoo are now centrally collected and transported to an eastern states recycling plant where they are cut up to have their components reclaimed, with the remaining materials disposed of responsibly. • Continued to recycle plastics, paper, cardboard, aluminium cans, batteries, scrap metal, green waste and soil. • Sourced raw materials sustainably where possible with 100% recycled timber used in the new Australian Wetlands boardwalk. • Appointed Perth Waste to provide an integrated waste management service. 59
