The actress, who plays vampire bar owner Pam in the hit TV series, is producing a film called Out of Africa with her husband, South African musician Abri van Straten, and donations had reached $24,150 (£15,373) when WENN went to press.
The documentary is being made to highlight the dangers facing the animals as hunters attempt to obtain elephant tusks and rhino horns to sell on the black market.
In a statement on fundraising website KickStarter.com, Bauer van Straten writes, "I will be taking a camera crew to Kenya to ask Africans, the on the ground experts and heroes; what is happening, what the possible solutions are and, how can we help you?
"They are living this crisis and working very hard to stop it, they know what can be done - they just need a larger voice.
"Together is the only way elephants and rhino may make it and also the only way I will be able to make this documentary. In the last six months 2 (sic) species of rhino have gone extinct and more are on the brink. I don’t think we can afford to wait to do something."
