The end of the game is triggered when at least 1 of the 3 possible end conditions is met at the end of a turn.

The 3 end conditions:

1. You have supported 4 Conservation objectives, so all 4 of your Conservation Achievement markers are on the Conservation board.

2. You covered your Zoo map completely, so there is not a single empty space left on it.

3. The pile of face-down tiles is empty.

If, at the end of your turn, you’ve met condition 1. and/or 2. take the 10-point End-of-game marker. Then everyone else gets 1 more turn (excluding you). After that, move on to the final scoring.

If the pile of face-down tiles is empty after you have triggered the end of the game, shuffle all the discarded tiles to form a new pile.

If you also meet condition 1. and/or 2. on your last turn, after someone else has triggered the end of the game, take a 5-point End-of-game marker.

If you meet condition 3. before one of you meets condition 1. or 2., the game ends immediately after your turn. Directly proceed to the final scoring.
