The green plastic mesh is from sod rolls (sod companies wrap sod rolls in this mesh) and it is also used in seeding lawns where a straw layer is added on top as a mulch. The straw is held together with the plastic mesh.
In our neighborhood, it was used with the construction of some new homes - most likely where this chipmunk got entangled in it.
I have seen several instances where the mesh surfaces and gets clipped by lawn mowers, people trip on it and where the straw blows away leaving the plastic mesh exposed. It certainly should be considered a hazard to wildlife (like most plastic items) and I would hope that sod companies will not continue to use this mesh.
