Wildlife Importance

Malus angustifolia provides a food source for small mammals such as squirrels, opossums, rabbits and deer as well as many species of birds such as bobwhites, grouse and pheasants 3,4.  They also attract local species of  bees, which pollinate the trees 4.   


 In Maryland it is listed as S3, which means that it is not under direct threat, but is relatively rare in Maryland so it is monitored closely 5. Generally, they do not do well with flooding and are endangered in Florida and Kentucky 5.    It is susceptible to fireblight, cedar apple rust, apple scab, canker,  as well as to scale, borers and aphids ¹.

 Economic Importance

 Natural food sources for bees are indispensable to conserving bees in Maryland, which help the economy.  The sour fruit can be made into james and jellies ³.  The hard wood is used for making tool handles 4.
