found this info posted on another forum, just some of the wildlife conservation work he's done that some may be unaware of...
(even has a newly discovered breed of turtle named after him)
In memory of his wonderful mother, Steve founded the Lyn Irwin Memorial
Fund. All donations go directly to the Iron Bark Station Wildlife
Rehabilitation Center with 3,450 acres of wildlife sanctuary. He also
owns 83,000 acres of endangered Acacia Woodland in southwestern
Queensland called Westbore and started the Brigalow Belt Conservation
Project. That’s not all. Steve is buying up enormous portions of
Australia for the sole purpose of conserving habitats for wildlife.
Steve Irwin is responsible for starting endangered species breeding
programs for the Southern Cassowary, Koalas, Fijian Crested Iguanas,
Bilby Rhinoceros Iguanas, Galapagos Giant Land Tortoises, Aldabran
Giant Land Tortoises, Mary River Turtles, Peregrine Falcons, Komodo
Dragons, and Irwins Turtles -- a newly-discovered breed named after
Steve himself. He has also established breeding programs for such
vulnerable species as Tasmanian Devils, Wombats, Echidnas, Red
Kangaroos, Asian Small-Clawed Otters, Queensland Womas, Death Adders,
Rusty Monitors, Canopy Goannas, Yakka Skinks, Reticulated Pythons,
Burmese Pythons, Australian Green Pythons, Sea Snakes, Black Cockatoos,
Jabirus, Curlews, and his beloved Saltwater Crocodiles.
Steve has helped fund field studies for scores of species of
crocodilians, lizards, snakes, mammals, and birds in order to help
stave off their habitat destruction and learn exactly what it is those
species need to survive
