This method can be used for virtually indefinite storage of material without deterioration over a much greater time-period relative to all other methods of ex situ conservation. Cryopreservation is also used for the conservation of livestock genetics through cryoconservation of animal genetic resources .
Remediation technologies are many and varied but can generally be categorized into ex-situ and in-situ methods. Ex-situ methods involve excavation of affected soils and subsequent treatment at the surface as well as extraction of contaminated groundwater and treatment at the surface. In-situ methods seek to treat the contamination without ...
Both in situ and ex situ processes were utilized to treat over 35,000 cubic meters of contaminated soil. The ex situ treated soil was mixed with Portland cement by a pugmill then placed on top of the in situ treated soil. This created an excellent base for pavement to be placed over the site.
Bioremediation techniques can be classified as (i) in situ techniques, which treat polluted sites directly, vs (ii) ex situ techniques which are applied to excavated materials. [8] In both these approaches, additional nutrients, vitamins, minerals, and pH buffers are added to enhance the growth and metabolism of the microorganisms.
Ex situ remediation refers to reactions performed outside the natural habitat of these organisms. Increased microbial activities through aeration , irrigation , and creation of bio-piles. Increased degradation activities via turning of polluted soils and addition of minerals and water.
In-situ conservation involves protecting or restoring the habitat. Ex-situ conservation, on the other hand, involves protection outside of an organism's natural habitat, such as on reservations or in gene banks, in circumstances where viable populations may not be present in the natural habitat.

Phytoremediation technologies use living plants to clean up soil, air and water contaminated with hazardous contaminants. [1] It is defined as "the use of green plants and the associated microorganisms, along with proper soil amendments and agronomic techniques to either contain, remove or render toxic environmental contaminants harmless". [2]
There are eleven possible conservation roles [14] [13] that are given to each species that is evaluated by the assessment. These roles are as follows: Ark, Rescue, In situ Conservation, In situ research, Husbandry research, Applied Ex situ Research, Mass Production in Captivity, Conservation Education, Supplementation, Biobanking, and doing ...
