Getting Rid of a Color in a Single Layer

[ttibsen]

So this time the problem is a bit different. I still want to get rid of the white in the trees but this time everything is on a single layer. Is this possible?

With a little bit of fiddling and using the same methods @Imaginerie gave before. 

• Make a duplicate of the whole layer.
• Draw around the all the trees roughly.
• Invert the selection, and delete the part of the image not needed.
• Clear that selection. 
• Now use the magic wand to select all the black pixels of the trees.
• Inver the selection and delete.

This should remove all the pixels not needed.
