In the Netherlands and some other parts of Europe, black locust is one of the most rot-resistant local trees, and projects have started to limit the use of tropical wood by promoting this tree and creating plantations. The fact that old growth forests where logged long ago combined with the push to use this wood instead of endangered tropical wood has created a shortage of this valuable tree worldwide.

Black locust is a typical early successional plant, a pioneer species, and it grows best in bright sunlight and does not handle shade well. [7] Young trees are often spiny, but mature trees often lack spines. [11] These ecosystems have been decreasing in size, and black locust is contributing to this reduction; when black locust invades an area, it will convert the grassland ecosystem into a forested ecosystem where the grasses are displaced. Black Locust can be a really fast growing tree. It can be easily propagated from roots, softwood, or hardwood[7][17] and this allows for easy reproduction of the plant. When Black Locust posts, timber and poles became less plentiful, farmers would burn the lower end of each post, timber or pole over an open fire to seal the wood to prevent water penetration. [4] Another common name is false acacia,[5] a literal translation of the specific name (pseudo meaning fake or false and acacia referring to the genus of plants with the same name). Honey locust trees grow long, twisted pods. When growing in sandy areas this plant can enrich the soil by means of its nitrogen-fixing nodules, allowing other species to move in.
