Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Manchurian smartweed faces severe population decline primarily due to wetland habitat destruction and agricultural conversion throughout its native range in northeastern China and adjacent regions. Urban development and water management projects have eliminated many of the seasonal wetlands and marshy areas essential for this species' survival. Climate change is altering precipitation patterns and water availability in its already limited habitat range, while invasive plant species compete for resources in remaining suitable sites.

Threat summary

Habitat

Manchurian smartweed inhabits seasonal wetlands, marshy areas, and the margins of shallow ponds and streams in temperate regions of northeastern Asia. The species requires areas with fluctuating water levels and nutrient-rich soils, typically found in lowland floodplains and agricultural wetland margins.

Frequently asked questions

Why is Manchurian smartweed classified as Endangered?
Manchurian smartweed is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Manchurian smartweed faces severe population decline primarily due to wetland habitat destruction and agricultural conversion throughout its native range in northeastern China and adjacent regions. Urban development and water management projects have eliminated many of the seasonal wetlands and marshy areas essential for this species' survival. Climate change is altering precipitation patterns and water availability in its already limited habitat range, while invasive plant species compete for resources in remaining suitable sites.
