I've been playing around with forestry specialisation and until now have always placed those areas on the map where it shows the darkest green. In that way you import less raw material. Looking at my latest city I noticed, where I have been greening up my roundabouts by densely planting my own trees, the natural resource overlay showed these areas are suitable for forestry specialisation.
Just carried out a quick experiment. I chose a blank white area of land, created forestry specialisation and 100% of buildings were imports of raw materials as you would expect.
I de-zoned the area then planted lots of trees. The area greened up according to the natural resource overlay. Then I zoned industrial and sure enough lots of plantations cropped up, producing their own raw materials.
Last experiment, made two rectangles with 2 lane roads each containing an enclosed area of 8x16 squares in blank land. Greened one up by adding lots of trees, left the other white. Then zoned both rectangles with the forestry specialisation. The area where I had planted lots of trees prior to zoning produced all plantations, the other produced all support buildings.
Is this the way it is supposed to work?
This may be common knowledge of course sometimes I can be a bit slow
but if it's true then basically you can create your own productive forestry areas no matter what the original maps say, at the cost of planting your own trees of course...
