How many of each dinosaur do you need for it to be happy? How many dinosaurs in a pen is too much for some dinosaurs?

Note: Ratings can change based on how complete the Genome is. I will use my genome %'s next to the rating.

Enclosures And Terrain

Instead of using the hard to decipher numbers in the information panel of the dinosaurs, I'm going to classify each dinosaur as a Tiny to Huge exhibit based on their minimum requirements, and list their Tree or Grassland needs as 'Very Low' to "Very HIgh' based on how much of their exhibit they want covered.

Note 1: Water counts as whatever you put it on. If you fill a area of trees with water, it still counts as Forest. If you fill a open plain with water, it still counts as grassland.

Note 2: The larger their exhibit, the more forgiving they are on required terrain.

Note 3: You don't to make their exhibits as small as I'm showing. I'm just doing this so you know the smallest they'll accept.

I tested these by putting each dinosaur in the enclosures pictured above and adding trees one by one until they were happy. If they were always in the red for both grassland and forest, i upgraded them to the next size pen. For scale of reference, you can fit a Hammond Creation Lab perfectly inside the Small enclosure.

Exhibit Key:

Tiny - Example: Anklyosaurs, Struthiomimus and other -mimuses
Small - Example: Low social Ceratopsians (Pentaceratops, Chasmosaurus, etc)
Medium - Example: (Suchomimus, Stegosaurus)
Large - Example: (Tyrannosaurus, Spinosaurus, Mamenchisaurus)
Huge - None

Terrain Key:
Jurassic World Evolution - Dinosaur Requirements image 16

Very Low - Barely needs any of that terrain type
Low - Requires a little bit of the terrain type
Medium - Requires a moderate amount of terrain type
High - Requires a large amount of the terrain type
Very High - Majority of the enclosure better be that terrain type

Extra: My Combinations

This is what I use, and it seems to work. They get along, their populations desires match, and their terrain requirements work together. It also allows 1 or 2 extra of the herding dinosaurs so that if one dies you aren't immediately in trouble of a rampage.

My picture shows you the size of the enclosures i made for each grouping. Some of the enclosures are bigger than they need to be (Pen Q and L are an example), while others are the bare minimum the dinosaurs would accept (Pen G, F, H, J, R, are examples).

Note: I do not breed Camarasaurus, Deinonychus, Indominus Rex, Indoraptor or Dracorex in my parks due to their hard-to-please temperments.
