The greater rhea is considered a Near Threatened species according to the IUCN, and they have a decreasing range of about 6,540,000 square kilometres (2,530,000 sq mi).
The species is believed to be declining due to increased hunting and the conversion of central South American grasslands to farmland and ranchland.
The populations of Argentina and Uruguay are most seriously affected by the decline.

Farmers sometimes consider the greater rhea pests, because they will eat broad-leaved crop plants, such as cabbage, chard and bok choy.
Where they occur as pests, farmers tend to hunt and kill greater rheas.
The burning of crops in South America has also contributed to their decline.

International trade in wild-caught greater rheas is restricted as per CITES Appendix II.

The rheas in Germany are legally protected in a similar way to native species.
In its new home, the greater rhea is considered generally beneficial as its browsing helps maintain the habitat diversity of the sparsely populated grasslands bordering the Schaalsee biosphere reserve.
They are however considered as a threat to local farmers and described as an invasive spieces since 2015 according to the NHBS .
German authorities have issued 'alternatives' to culling the birds which still spark controversy.
