The Dawn of Pangaea - What's different to Forests?

About The Dawn of Pangaea, from BoardGameGeek:

At the dawn of time, the first spirits were born - gentle and tireless in their mission to spread life across the barren land of Pangaea. As players, you enter this mythical age, growing your trees and performing rituals to awaken Gaia's dormant energy and summon elemental creatures to roam and nurture the growing continent. In the Dawn of Pangaea, you and your fellow players act as the first spirits of Pangaea. On your turn, you must choose 2 of the 5 actions that are available to you e.g. planting seeds, growing trees and expanding your forest. Anytime during your turn, you may also play blessing or favor tokens, that you have collected during the game. These tokens will also allow you to summon the ancient guardians with their powerful abilities. Play Ritual cards to score points for growing your trees across different biomes or for attracting creatures that require a specific weather condition. With every point that you gain from these rituals, you climb higher up the sacred Mountain. The first player who reaches the top of the mountain, triggers the end of the game and initiates the final scoring. The player with the most points wins the game and gains the high blessing of Gaia. -description from the publisher
