Morus nigra is listed as Data Deficient because the native wild distribution is not known with any certainty. Hence, the range, its population size and trends and threats to the wild population of this species are not known. Even if the native range were confirmed to be in Iran, distinguishing between the wild population and naturalised plants from cultivated sources would be very difficult, as this species have been cultivated for thousands of years.

Due to extensive cultivation and subspontaneous introduction of Morus nigra it is difficult to determine the native distribution of the species. The species is cultivated throughout the temperate, subtropical and tropical zones of Asia, Africa, Europe, as well as South and North and America. It is suspected to be native to Iran.

There is no information on population trends.

This is a small tree, up to 10 m in height. The species has been cultivated for thousands of years throughout the temperate, subtropical and tropical zones of Asia, Africa, Europe, as well as South and North and America. Morus nigra can grow in a wide range of topographical, climatic and soil conditions and planted specimens occurs from sea level up to altitudes as high as 4,000 m (Tutin 1996), but the native habitat is unknown.

As the native range is not known, threats to the wild population cannot be determined.

The fruit is edible and the species is used for medicinal purposes for a wide range of purposes (Ahlawat et al. 2016). This species is commonly cultivated.

It is known to be kept in at least 131 ex situ collections (BGCI 2023). Research is required to determine what the native range of this species was and if there are any plants which could be called wild.
