In 1996, Tran Triet as part of his PhD research at the University of Wisconsin at Madison, recommended to the Kien Giang government that they conserve 60,000 hectares of seasonally flooded grassland in the southwest of the province. These grasslands are characterized by Eleocharis whose roots are the preferred food of the iconic Sarus crane, which migrates from its breeding sites in the forests of eastern Cambodia to spend March and April feeding in the delta. Another notable grassland plant is Lepironia, which local people harvest to weave handicrafts.
