Status:

Japanese Black Pine is native to coastal areas of Japan and Korea. It is more salt-spray resistant than any of our native pines. In the twentieth century, it was introduced to some Atlantic coastal areas and along the Chesapeake Bay, but has suffered from insects and diseases and has fallen in esteem. In Delaware it is considered invasive (USDA, undated).

Description:

Japanese Black Pine is noted for its silky whitish candle-like terminal buds, the lack of a prominent central leader, and the irregular and asymmetrical shape it develops as it ages (North Carolina Extension, undated).

Where to find:

On Assateague Island, especially in the state park.

Relationships:

This pine's seeds are a popular food source for some visiting winter bird species, such as Red-breasted Nuthatch (regular) and Red Crossbill (rare).

There are 22 records in the project database.
