The last couple of games I haven't had a good national park location with enough trees that I felt it was worthwhile to save them.
However I've come up with an alternative that is nearly as good - put National Park in an area of irrigated grassland - possibly where you chopped all the trees originally.
Pair with Globe Theatre. Each grassland farm produces four food which means that if you work 20 grassland farms you can grow to size 40 and support 20 specialists - exactly the number you would get free from 20 forests on the same terrain.
You miss out a little on the production of the forest tiles themselves. But you gain high levels of trade income with a city this large to compensate. Also you got the extra hammers from forests you chopped.
With both these wonders it appears that a size 40 or so city is fairly achievable. Add in Sids Sushi for extra effect.
