珀斯动物园狮子园丨澳大利亚丨Iredale Pedersen Hook

在非洲，由于盗猎和栖息地的丧失，狮子已处于极度濒危的状态。珀斯动物园新的狮子展区符合饲养、展示和繁育的国际标准，为动物创造出良好条件。

The new Lion Exhibit completely replaces the old exhibit, bringing the exhibit up to current international standards for housing, exhibiting and breeding Lions. Lions are critically endangered due to poaching and habitat loss in Africa.

狮子园由两个展览场共同组成，中间通过观景台进行分隔，为公众创造出身临其境的观赏体验。改造后的观景台焕然一新，以工程玻璃取代了原有外墙。

The facility consists of 2 exhibit yards, separated by a viewing bay providing an immersive viewing experience for the public. Old viewing bays were renovated and their facades replaced with engineered glass.

改造工程共包含两期，第一阶段是对旧的母狮园进行改造，包括狮穴正面、展区大门、滑道以及主要安全屏障的建设。设计从原型中汲取经验，对改造的最后阶段进行把控，新建了围栏与跑道，并对现有观景台的玻璃外墙进行更新，增加狮穴、幼崽场和服务区等新的狮子繁育设施。

The 2-stage renovation allowed for the housing on the old Female Lion during the first stage of the works, and to prototype new den fronts, exhibit gates, slides and exhibit hardware and a major lion-safe barrier. The lessons learned from the prototyping were then applied to the final stage; consisting of new fencing, linkage races, replacement glass facades to existing viewing bays and a new lion breeding facility consisting of dens, cubbing yard and service areas.

饲养区需要提供高度灵活的狮穴和跑道，以便在不经过展览区的情况下满足狮子移动的需要，进行检查、喂养、称重等活动。这个过程需要经过严格高风险的把控，因为系统和机制一旦发生故障将带来致命的后果。

The keepers require a high level of flexibility with dens and races to safely move Lions around the facility without using the exhibit yard, to examine, feed, weigh and provide enrichment to the animals. This process is exacting, high risk and potentially fatal if the systems and mechanisms fail.

IPH 事务所与饲养员们密切合作，通过滑道的设计回应了狮穴中的流程和活动。基于颜色的识别系统便于饲养员之间对需要操作的狮穴和滑道进行沟通。颜色系统对红绿色盲也进行了考虑，该症状在成年男性中出现的几率可达 8%。

IPH 与饲养员密切合作设计滑梯，以响应兽穴中所需的流程和活动，包括开发一种基于颜色的识别系统，使饲养员能够沟通操作哪些兽穴和滑梯。该系统考虑到了红绿色盲——这会影响 8%的成年男性。

设计保证了狮穴内部的自然通风与采光，岩床下方的内嵌加热元件仅用于寒冷的夜晚。此外，狮穴和展示区都铺设了闭路电视系统，以便在未来对繁育和幼崽进行视频捕捉。

The dens are naturally vented and lit, with in-slab heating elements under sleeping areas only for cold nights. The dens and exhibit areas have conduits for a future CCTV system to allow for video capture of breeding animals and cubs.

展览区的设计主要包括钢屏障的开发，这种材料经济实用，并具有较高的耐用性和可维护性，符合当前安全收容狮子的标准。由于狮子通常会喷洒尿液来标记它们的领地，而酸性液体对钢和锌具有很强的腐蚀性，因此屏障外涂上了一层环氧树脂面漆，以形成专业的保护系统。两个区域可分开单独饲养动物，也可以连接起来形成更大的院落空间，这种设计能够保证狮子的安全繁殖，将具有攻击性的雄性狮子与幼崽分隔开。

The exhibit yard design included developing a primary steel barrier that was cost effective to install, met the current standards for safe containment of Lions and was durable and maintainable in the future. Lions spray urine to mark their territory and this acidic spray is highly corrosive to steel and zinc- so a specialist protective system was applied to the fencing- with a high build epoxy top coat. The 2 yard spaces can be used separately for animal separation- or joined together to form a larger yard space. This allows for safe breeding- with the possible separation of aggressive males from the cubs.

设计采用 3D 可视化对景观屏障、游客视线和动物视线进行了分析，在游客可视度和动物压力间取得平衡。模拟的岩石洞穴和安装有加热元件的“岩床”能够吸引狮子在寒冷天气前往限定区域休息。新建的主观景台由圆木和茅草制成，展览场路线两侧的主要屏障则以填芯混凝土块、钢和玻璃制成。观景台为游客提供了与狮子面对面接触的体验，也保证了两个院落中的狮子能够产生视觉联系。

3D visualization was used to design the landscape screening, sight lines for visitors and sight lines for animals – allowing a balance between visibility and animal stress. Mock rock caves and “bed rock” areas were installed- with in-slab heating elements to encourage the Lions to lie in key locations in cold weather.
