The wording of how to count sprout icons on page 5 of the rulebook may be ambiguous. It should be read as the following:

The size of any habitat in your land is the number of adjacent tiles with matching edges. Additionally, some habitat tiles feature a sprout icon that indicates a particularly lush feature—this icon adds +1 to the size of the habitat type it appears on; it does not increase the size of any other habitat type on the same tile.

Although not explicitly stated in the rulebook, Predator and Primate cards must be played only from your hand. They cannot be played directly from the common tableau.

In the End of Turn phase, consider all energy in the Poachers current segment of the rondel as spent energy. In effect, they spend the energy when determining the size of the animal tile they gain for that round based on the available energy.
