Can you help me find a similar game?

Ok so a long time ago, around 2000, I played a game called The Gungan Frontier. The basic idea is that you choose some animals to start an ecosystem with, and attempt to keep that ecosystem in balance by having the right amount of animals in the foodchain. Despite the shitty graphics and other shortcomings, I really enjoyed the ecosystem management aspect of the game and was wondering: do you have any suggestions for more recent games that involve setting up and maintaining an ecosystem? Thank you for your suggestions =)
