I just wanted to add my piece related to this...
I was also dissapointed when I cleared the jungle to find no bonus grasslands. I also had many workers on the starting island clearing all that jungle. No bonus shields anywhere did have an impact on productivity for my primary core of cities.
However, I do remember cracker giving us an explanation of his reasoning after the game had started. The reason was so that everything was kept equal for each player which made comparison of games and skill much easier. On this island, most of the jungle squares were relatively equal to each other. The decision to clear one jungle tile instead of another one next to it would be mostly random and based on city positions, ect. It essentially would have become pure luck for one player to find a bonus grassland while another player cleared the next jungle square over and did not find one. Thus giving the first player a slight advantage in QSC score without accurately reflecting the skill of that player. By removing all the bonus grassland, cracker removed any extra variables for our games and made the starting situation equal for each player. (cracker, please correct me if I am mistaken)
