Threats [top]

Major Threat(s): A hybrid zone between C. lami and C. minutus has been identified. The two species were formally separated by a wide humid zone but rice farming has reduced the swamp to a dry region and the two species have been brought together (Gava and Freitas, 2003). Urbanization and the development of agriculture, particularly rice and soybeans, in its limited geographic territory, make C. lami a threatened species (Fernandes, 2007).

Conservation Actions [top]

Conservation Actions: There is no information available about any conservation measures being made to protect this species. Further research is necessary to clarify the true status of this species.
