Just delete particle where the angle between the emit location normal 
and the Y axis is greater then your desired threshold :

Subject: ICE strands generation for Conifers

I am looking at generating a Spruce tree using T-Gen or SpeedTree for the
geometry and the generate the needles using Strands. To that end I would
like to generate the strands growing from the top and sides af each
twig/branch but not the underside. My question is if there is a way to
isolate either of these areas in ICE or otherwise and perhaps generate a
cluster or weightmap I can use in ICE?

The only way I have found so far is to select Y+ in the Texture Editor which
gives me samples of the area I want. How do I select vertices or polygons
from this? Also is there a quicker way to select this area directly in ICE?

Thanks.

or put a empty weightmap on the object
add a non simulated ice tree
get point normal---> 3d vector to scalar (Y)---> fcurve---> set data weight
map weights
