One of the many cool things to drop as part of Civ VI's Vietnam and Kublai Khan pack last week is the introduction of a brand new district; the preserve. It can be built anywhere - except next to a city centre - that gives boosts to appeal, housing, and even sets off a culture bomb to claim surrounding tiles.
Like the 'national parks' tile improvement, these districts lean into some of the 4X game's more eco-friendly content that incentivise you to plan ahead with your land, and keep some of it free from infrastructure. Preserves come with two building options, the grove and the sanctuary, that can provide different yield buffs to surrounding unimproved tiles depending on which one you choose. The grove boosts food, faith, and culture, while the sanctuary favours science, production, and gold.
In short, there is a lot of potential to use the preserves, in combination with other aspects of the game, to really enhance the potential yields of your empire depending on what kind of start you have, how you place your preserves, and making full use of any appeal-based bonuses.
