"It's important for conservation in general, and uses all the 'k's really - karearea, kokako, kiwi and kaitiaki."
The Wingspan group's trip has been sponsored entirely by Sheikh Khalifa Bin Zayed Al Nayan, the president and ruler of the UAE.
Ms Stewart said the festival would celebrate the history of falconry.
"Falconry goes back 4000 years; it's the longest form of hunting."
Her group would also attend a falcon-specific desert camp, which will have workshops, camels, hawking, horsing and a number of traditional events, she said.
Wingspan, a charitable trust, has a history of supporting research projects, and contributed to the successful submission to UNESCO for falconry to be inscribed as "an intangible cultural heritage of humanity".
