I am porting this YouTube tutorial to the Blender 3 nodes https://www.youtube.com/watch?v=WzIdcGdGXLM. I have successfully ported mostly everything over to Blender 3 up until about the 33 minute mark. the part that I'm having trouble with is getting the branches to appear only on the top approximately 3/4 of the tree trunk. This is what the video looks like at this point:

This is what my file looks like at this point:

It's substantially the same as the video tutorial except for the fact that I can't find geometry nodes in Blender 3 to mimic the attribute math less than and point separate nodes to achieve the desired effect. Here's a Blender file with my tree simulation:

Can someone please show me how to get the branches to not populate on the lower section of the tree trunk?

The Attribute Math node is no longer necessary because the ordinary Math node now accepts fields as inputs and produces a field as output. The Point Separate node has been replaced with the more general Separate Geometry node.

Here’s an example of how the new nodes might be used together in a configuration similar to the one in the video:
