Prickles came into our care as a tiny, wide-eyed orphan—rescued after his mother was tragically killed by dogs on a nearby farm. From that moment on, he became part of our family, wrapped in warmth and raised with the kind of love and devotion that only a little abandoned porcupine could inspire.

How Retired Architect Joseph Zwick left a lasting mark at Cango Wildlife Ranch, Oudtshoorn — June 2025
Conservation is often powered by passionate volunteers — and every so often, one leaves behind a legacy that echoes long after they’ve gone. This past May, retired architect Joseph Otto Zwick spent three weeks enriching the lives of lemurs, aviary birds, and staff alike during his stay as part of the Wild Animal Volunteers program.
Originally from Quincy, Illinois and now based in Southern California, Joseph brought more than goodwill. With a family history rooted in German craftsmanship and design, he arrived with a lifetime of architectural experience, a creative mind, a plethora of Artistic skills, a deep love for wildlife, and an eagerness to contribute meaningfully in his retirement years.
One of his first projects was an enrichment hammock for the Brown Lemurs — repurposing old firehoses, plastic tubing, and rope. Though the first attempt left his hands worse for wear, the lemurs were pleased, and Joseph was inspired to continue. Using recycled materials and his sharp design eye, he went on to build elevated rope swings, trapezes, and hammocks — all strategically placed to catch maximum sunlight for the lounging lemurs.
“Designing for animals isn’t all that different from people,” he said with a smile. “You assess their needs, study their behavior, and build around their comfort and joy.”
But it wasn’t just lemurs that left an impression on Joseph. Two resident Blue Duikers, affectionately nicknamed Polly and Josephine (or "Josie"), took a particular interest in his daily work. Josie became a regular companion, quietly watching from nearby while he installed new enrichment items.
“She was good company,” Joseph said warmly. “She made me smile every day.”
His days at the ranch were filled with hands-on projects, from crafting woven birdhouses in the aviary to tackling repairs for enrichment structures across the park. Though he faced tool shortages and the occasional supply challenge, his determination never wavered. “Animals are easier to please than humans,” he joked. “And their gratitude is quiet but obvious.”
Joseph’s time at Cango Wildlife was also a reflection of his values — of simplicity, patience, and the joy of creating with intention. He noted how rewarding it was to see animals interact with objects he designed. “It gives me purpose. Life is precious, and anything I can do to make these animals safer, happier, or more entertained feels deeply worthwhile.”
As he prepared to return home, Joseph left behind more than just hammocks and birdhouses. He left behind a blueprint of compassion, purpose-driven design, and a reminder that conservation isn’t just about protecting — it’s also about creating
Thank you, Joseph, for reminding us that it is not just about building structures... its about building stories, legacies, and a lasting impact!
