hey, kayleigh!
although i'm not a mesh/map maker, i managed to find some that will hopefully serve you well.
the download links should be either on the right of the page or in the description beneath the images.
http://fav.me/d816u1c (http://fav.me/d816u1c) } priderock from 'the lion king'
http://fav.me/d72vytb (http://fav.me/d72vytb) } leafless tree (quite big, you may want to resize it)
http://fav.me/d77rpzz (http://fav.me/d77rpzz) } baobab tree/rafiki's tree from 'the lion king'
http://fav.me/d8ek6in (http://fav.me/d8ek6in) } a bunch of animal meshes, featuring girrafes
http://fav.me/d89ottm (http://fav.me/d89ottm) } den/cave/hill meshes (large; ideal for prides/clans/packs)
http://fav.me/d75gbrc (http://fav.me/d75gbrc) } leafless bush
http://fav.me/d8x95ad (http://fav.me/d8x95ad) } cactus and a couple of rocks, once again quite large, so you may want to resize them in-game
http://fav.me/d6wcvwc (http://fav.me/d6wcvwc) } corn mesh, but i'm sure it could serve quite well among other grass/bush meshes
hope i helped!
if you need anything else, let me know!
