Conservation

''Isoetes sinensis'' is recorded to be a critically endangered species due to industrial development and

agricultural expansion Agricultural expansion describes the growth of agricultural land (arable land, pastures, etc.) especially in the 20th and 21st centuries. The agricultural expansion is often explained as a direct consequence of the global increase in food and ene ...

. This species occupies freshwater environments and within terrestrial systems. In order to help conserve this species, amplified fragment length polymorphisms (AFLPs) were used to research the genetic variation of it and the population structure of seven extant populations of the species. This investigation helped provide useful data for creating conservation strategies to help preserve the species.
