Low nutrient; deficient in one or more essential plant elements (for example, phosphorus, nitrogen, potassium).
aquatic areas of low productivity.
Refers to fresh waters with poor nutrient supply and low productivity.
A water body (usually a lake) that is characterized by having a low concentration of nutrients and low productivity.
Underfed or with low nutrient levels
(Gr. oligos: a little; trophĂȘ: food) adj. Of a lake characterized by a low accumulation of dissolved nutrient salts, supporting but a sparse plant and animal life, and having a high oxygen content owing to the low organic content.
the state of a poorly-nourished, unproductive lake that is commonly oxygen rich and low in turbidity.
A term applied to lakes and ponds with clear water and low levels of nutrients.
refers to a region with low concentrations of nutrients and low biological productivity, an ocean "desert" like the Sargasso Sea (compare eutrophic and mesotrophic)
A condition of lakes characterized by low concentrations of nutrients and algae and resulting good water transparency. An oligotrophic lake has less nutrients than a mesotrophic or eutrophic lake.
Waters low in nutrients and organic production, typically rich in biodiversity
Oligotrophic waters are nutrient poor.
Waters that are nutrient poor and have little organic production (Gr. oligos small, trophein to nourish).
Having low levels of primary productivity or nutrients
OL-ah-go-TRO-fik A lake with few nutrients, usually very blue. 880
The low state of nutrients in a water body determined by the average concentration of total phosphorus and algae growth (productivity) that the phosphorus can sustain.
Very unproductive lakes low in nutrients and algae, usually very transparent with abundant hypolimnetic oxygen if stratified.
Reservoirs and lakes which are nutrient poor and contain little aquatic plant or animal life.
a nutrient-poor body of water.
Refers to water bodies or habitats with low concentrations of nutrients.
Waters with low primary productivity because of limited supplies of nutrients.
Low in nutrients and in primary production.
a body of fresh water that contains few nutrients and few organisms.
Water that is low in nutrients, with relatively low organic productivity.
having low levels of plant nutrients and an abundant supply of dissolved oxygen. Compare eutrophication
Lacking in plant nutrients and having a large amount of dissolved oxygen throughout. Used of a pond or lake.
deficient in nutrients needed for plant growth
one of the four trophic state categories, describes a lake with clear water, low nutrients and few water quality problems; the oligotrophic waterbody is capable of producing and supporting relatively small populations of living organisms (plants, fish, and wildlife); Trophic State Index value below 50.
Descriptive of crystal-clear lakes characterized by cold water fish species, low nutrient content and generally pristine features.
a body of water that is deficient in dissolved nutrients, but can be rich in oxygen.
possibly nutrient poor, less fertile
Describing a body of water in which nutrients are in low supply.
refers to a body of water which is poor in dissolved nutrients and usually rich in dissolved oxygen. Opp: eutrophic
having a low trophic status; usually applied to water bodies or to soil water in peaty or hill areas where the underlying rocks are of low base status.
Deficient in nutrients, unstratified, and free of pollutants.
from the Greek for "poorly nourished". Describes a lake with low plant growth and high clarity. Oligotrophic lakes contain little organic matter and have high dissolved oxygen content.
lentic water body with a small supply of plant nutrients and having a large amount of dissolved oxygen throughout.
Lakes: Deep clear lakes with few nutrients, little organic matter and a high dissolved-oxygen level.
used to describe clean, relatively unproductive lakes and estuaries having low levels of plant nutrients and algae with high water clarity and dissolved oxygen.
organic nutrients in poor supply or transiently available, opposite to eutrophic. Common in soil and water.
Oligotrophic refers to any environment which offers little to sustain life. This term is usually used to describe bodies of water or soils with very low nutrient levels.
