I think it would be really cool if they added grass with wildflowers as a terrain tool (or just as a placeable plant if this is not possible) into the game, maybe as part of a European pack (or better yet just in a free update!). This would be awesome if people wanted to add a wildlife area which is just left to nature (it would also be cool to have an option added to the education boards about why these areas are important for all native wildlife wherever you live) like some zoos (Yorkshire Wildlife Park for example) do have.
It would also make the empty spaces around the edge of your zoo more interesting whilst you build up the habitats, without having to spend hours placing trees etc. that you are likely to delete or move as your zoo grows!
