Unknown tree and shurbs

This tree is about 20' tall:

My best guess is that it is a serviceberry or crabapple.

This shurb is around 8' tall:

The second shrub is small, about 3' high:

These are all growing in a Maryland stream valley.

Thanks. Is there an easy way to tell if it is native or invasive?

 

1. A Malus sp.
2. Euonymus sp.
3. Agree with saltcedar, a Berberis.

 

All are liable to be of Asian origin, the crab perhaps a hybrid but the spindle looks like Euonymus alatus, the barberry like B. thunbergii. Native B. canadensis is supposed to be distinguished from B. vulgaris and B. thunbergii by producing leaves with jagged margins. Various photos online captioned as depicting this species show smooth or inconspicuously toothed leaf margins - but perhaps these are all misidentified. People not well acquainted with the cultivated and naturalized plants of a region often misidentify species of foreign origin as those which are expected to occur natively there.

 

This was the information that I was looking for, thanks all.

 

Apple tree looks similar to Malus baccata or hybrids of this species - notice lack of calyx on the fruits.
