The EnvironmentOntology (EnvO) terms refer to key environment-types that may be used to facilitate the retrieval and integration of a broad range of biological data.
We suggest to include three of the EnvO terms that could help your data to be reusable: environment (biome), environment (material), and environment (feature). More details about these three terms (and the format used to include them correctly) are to be found on the field descriptions of our template.
If you still have doubts about the EnvO parameters we could support you with that.
