Impoverished Pinweed is an unusual species of the Athabasca Sand Plain
Impoverished or Largepod Pinweed had never been detected in Alberta prior to 2012, when it was discovered by ABMI staff. Additional surveys as part of the Rare Plant Project resulted in the discovery of several other populations. This species lives in very sandy soils in Alberta’s Athabasca Sand Plain and is strongly associated with post-fire Jack Pine stands.
