In February 2009, the Vancouver Aquarium installed its first greenhouse with the intention of reintroducing the frogs into the wild. They housed 28 Northern leopard frogs (from three egg masses) in 2009, and 50 more tadpoles (from five egg masses) were added in May 2010. By spring of 2012, the frogs were mature enough to breed in order to ensure the future viability of the Northern leopard frog populations in British Columbia.
