Success in Monster Hunter Stories 3 relies on learning a few important things, and one of those is how to rebuild various environments.
Monster appearances vary depending on the location, but building up their numbers will benefit you over time. You’ll get access to higher-quality eggs, which will lead to stronger and better monsties for your team.
As someone who’s really interested in helping nature, I’ve found this guide to be super helpful. It basically walks you through everything you need to know about bringing different kinds of habitats – like forests, wetlands, or grasslands – back to health. It’s a complete resource for anyone wanting to get involved in habitat restoration!

How to restore habitats in Monster Hunter Stories 3
First, you need to progress through the game until you battle the Invasive Yian Garuga. This is the first Invasive monster you’ll encounter, and it’s a key part of the story, so you won’t be able to avoid it.
After you beat the Yian Garuga, you’ll be able to release monsties in any region. Releasing them will improve that region’s Ecosystem Rank.

- Once you open the Hatitat Restoration screen, select the area.
- The area will have an Element preference and an Ecosystem Rank that has four tiers: C, B, A, and S.
- You can release up to five additional monsties in every region aside from the ones that are native to it.
Let’s now find out how to increase the Ecosystem Rank of a habitat.
How to raise Ecosystem Rank in Monster Hunter Stories 3
Releasing a monstie raises a region’s Ecosystem Rank. It increases even faster if you find and battle stronger monsters. Adding mutated monsters – whether they’re endangered or native to the area – will also boost the Rank more quickly.

Here’s a list of different benefits you get when the Ecosystem Rank is high.
- Better eggs that have higher chances of having S-Rank genes (only possible if the Ecosystem Rank is at S).
- Eggs will have higher chances to reward you with eggs that typically hatch higher-level monsties.
- Certain mutations are only possible if the Ecosystem Rank is either an A or an S Rank.
- Dual-Type monsties
Mutations are helpful because they give your monstie creatures with two elements, making it easier to exploit enemy weaknesses. The elements your monstie gains from a mutation will be determined by the specific region you’re in for both of its elemental slots.
Restoring habitats and increasing their Ecosystem Rank offers many advantages. Plus, it’s essential if you want to unlock all the mutations in Monster Hunter Stories 3.
