It seems to be a wanted planted, that is not wanted(invasive).
*Prevention and Control
Do not plant autumn olive. Individual young plants can be hand-pulled, ensuring that roots are removed. Cutting, in combination with herbicide application, is effective. Hedges can be cut down using a brush type mower, chain saw, or similar tool, and stumps treated with a systemic herbicide like glyphosate or triclopyr. Application of these herbicides to foliage is also effective but is likely to impact non-target species. Herbivorous animals are not known to feed on it and few insects seem to utilize or bother it. Canker disease is occasionally a problem but not enough to be useful as a control agent.

Dave, interesting information. In fact, one of the critiques of permaculture that you sometimes hear is that it introduces non-native (and this case "invasive) species to an area where they shouldn't be planted.

I think there's always a struggle between using strictly native species vs. when to use introduced or naturalized species that uniquely serve a purpose that a native cannot. In this case, it looks like a rapidly spreading plant that would be a great windblock and shade producer, but tread extremely carefully (if at all) since the amount of fruit = massive propagation via birds spreading seeds....

Sometimes non-native is probably OK if there's no other alternative and the choice is a non-invasive variety.

Here's another good link about autumn olive: http://www.lib.uconn....­
