Change Earth

You crush the pebbles and pieces from the biome in your hand and touch the ground. From where you touched to 50 ft. outwards in a cylinder radius transforms into the biome you took the piece from. The ground changes, and the fauna in its wake does as well, and even the water. All creatures with benefits on this land gain the benefits and this stays this way until it is de-spelled. 

The biomes that you can use are: Swamp, Plains, Mountains, Hills, Forest, Jungle, River, Desert, Snowy Mountain/Location, Volcanic Area, Aquatic Area, Frozen Area. 

 Things such as trees will convert into the wood type of the biome, or if its a jungle a mini Oasis can be made by turning a portion of it to jungle. Plains like the Shadowfell, Elemental Plains, and Feywild can not be transformed due to the high amounts of anti-magic in the area. If an area is converted to an area with water, the ground will hollow out and begin to produce water.

All natural creatures (bears, wolves, squirrels, etc.) must make a Constitution Save, or will change with the area (such a brown bear becoming a polar bear or a salmon becoming a tropical fish)
