Relational slim: types of quality that require an additional entity in order to exist
A duck swimming in a pond is partially surrounded by air and partially surrounded by water.
x partially_surrounded_by y if and only if (1) x is adjacent to y and for the region r that is adjacent to x, r partially overlaps y (2) the shared boundary between x and y occupies a non-trivial proportion of the outermost boundary of x
Definition modified from 'surrounded by'.
Afforestation results in the expansion of a forest.
A process, p, results in the expansion of a material entity, m, if the spatial extent of m is increased as a result of participating in p.
A relation between a process and a disposition such that the existence of the disposition is caused by the execution of the process.
Experimental relation used in EnvO. A condition defines a restricted range of a given quality or combination of qualities. If an environment class, E, has_condition C, then all qualities listed in C are restricted to the ranges defined in C in E. This is not intended as a logical conditional.
An environmental material primarily composed of dihydrogen oxide in its liquid form.
Sediment is an environmental substance comprised of any particulate matter that can be transported by fluid flow and which eventually is deposited as a layer of solid particles on the bedor bottom of a body of water or other liquid.
It is recommended to use a combination of sediment terms to describe a more specific sediment type.
Water which contains a significant concentration of dissolved salts.
The threshold salt concentration for classifying water as saline varies, but typically begins at about 1,000 to 3,000 parts salt per million parts water or 0.1–0.3% salt by weight.
Water which has a low concentration of dissolved solutes, particularly that of sodium chloride.
The lower bound of solute concentration required for water to be considered freshwater is variable, but is always less than that of seawater, and often cited as less than 1 gram of solutes per 1 litre of water.
Sterile water is water which does not contain lliving organisms.
The narrow region of soil that is directly influenced by root secretions and associated soil microorganisms.
A portion of environmental material is a fiat object part which forms the medium or part of the medium of an environmental system.
Everything under this parent must be a mass noun. All subclasses are to be understood as being composed primarily of the named entity, rather than restricted to that entity. For example, "ENVO:water" is to be understood as "environmental material composed primarly of some CHEBI:water". This class is currently being aligned to the Basic Formal Ontology. Following this alignment, its definition and the definitions of its subclasses will be revised.
Environmental material derived from living organisms and composed primarily of one or more biomacromolecules.
A system which has the disposition to environ one or more material entities.
In ENVO's alignment with the Basic Formal Ontology, this class is being considered as a subclass of a proposed BFO class "system". The relation "environed_by" is also under development. Roughly, a system which includes a material entity (at least partially) within its site and causally influences that entity may be considered to environ it. Following the completion of this alignment, this class' definition and the definitions of its subclasses will be revised.
An aquatic environment which is determined by freshwater.
An environmental system which has its properties and dynamics determined by saline water.
An environment whose dynamics are strongly influenced by water.
A site which has its extent determined by the presence or influence of one or more components of an environmental system or the processes occurring therein.
Formerly, this class was an experimental class and a subclass of "environmental feature". It is now aligned to BFO. The class was not obsoleted as the core semantics maintained their stability through its transition.
An environmental material which is in a liquid state.
This is a defined class: most of its subclasses will not be asserted, but filled by inference.
An environmental system which is determined by materials bearing roughly homogeneous qualities.
Organisational class. Not intended for annotation.
environmental system determined by a quality
An environmental system determined by the presence of a plant rhizosphere.
An environmental system which is determined by a living organism.
environmental system determined by an organism
An environmental system determined by a green plant.
An environmental system determined by an animal.
This class (term) is defined by the lack of a quality (i.e. the lack of salinity or increased osmolarity), which is not best-practice ontologically. Use for annotation is generally discouraged and users should use classes which positively describe the material or environment sampled (i.e. stating the qualities the entity has, rather than those it does not).
Sediment which has its porespace filled by water which has very low levels of sodium chloride and/or other salts.
We do not specify numeric thresholds for saline vs. non-saline here, as this is variable. Consider specifying this on the information and/or data layer for your purposes. If you require an ENVO class with a fixed threshold, please request one using our issue tracker.
An environmental system which has its properties and dynamics determined by feces.
The label of this EMPO class is ambiguous, but pers. comm. with L Thompson (http://orcid.org/0000-0002-3911-1280) reveals that this is essentially limited to fecal samples.
An environmental system which has its properties and dynamics determined by a bodily secretion of a metazoan.
environment determined by a metazoan secretion
An environmental system which has its properties and dynamics determined by a substance produced by a plant.

An environmental system which has its properties and dynamics determined by a digestive tract.
This EMPO class includes examples of microbial environments determined by the "gut intestine, gizzard, crop, lumen, [and] mucosa".
An environmental system which has its properties and dynamics determined by a biofilm on the surface of a animal.

Sediment which has its porespace filled by water with increased levels of sodium chloride and other salts.
An environment which is determined by materials which bear significant concentrations of salts.
The thresholds for "significant" concentrations of salts vary widely and thus no committment is made in this class. Subclasses with more explicit thresholds can be made upon request.
An environmental system determined by a fungal structure.
An environmental system which has its properties and dynamics determined by sterile water.
This term can be understood as a negative experimental control primarily composed of sterile water. The quantity of sterile water used may be contaminated; to express pure sterile water, please use http://purl.obolibrary.org/obo/ENVO_00005791
