The organisation, like many others affected by the COVID-19 pandemic, is heavily supported by partners, sponsors and supporters.
Commercial activities like the plant sale not only encourage sales but also park visitation.
Nature Park’s general manager, David Thompson, said: “Plant sale on the weekend, two of those per year. It’s been going well, it’s been consistent. Same figures as last year, same numbers as last year, with all those contributions and plant sales going to our wildlife fund, and to the conservation of our animals and everything here.”
