Impacts: 

Altered trophic level
Negatively impacts animal health. a particular threat to prairies because it easily invades open areas and may compete for resources with native species, besides fixing nitrogen and thus affecting edaphic conditions. It is also undesirable on prairie reserves because it is a highly visible exotic when in flower. As a nitrogen fixer, M. albus also has the potential to alter the soil nutrient status and modify the environment in nitrogen-poor ecosystems, often making them more attractive to other invasive species.

Source? likely to be reintroduced: 

The risk of deliberate introduction to further countries is high as M. albus is sometimes seen as a potentially high value fodder crop. Seeds of M. albus are also sometimes introduced as impurities in seeds of other crops such as lucerne

Info Blurb: 

Easily invades open areas and may compete for resources with native species. As a nitrogen fixer, also has the potential to alter the soil nutrient status and modify the environment in nitrogen-poor ecosystems, often making them more attractive to other invasive species. Introduced as a fodder crop and through seed contamination.
