Laying out Foliage in Maya 2016

Hey there,

Does anyone know how to layout the foliage (Grass), scatter the leaves and other assets into Maya 2016?

I am nearing the end of texturing a Vehicle and I want to present it in a forest/jungle setting; so I'm looking at the Meadow and Forest packs atm but I'm wondering how I would import these into Maya.

I'm new to applying foliage into Maya so help would much appreciated! 

Thanks!
