We need to remove a number of trees that have been killed by some kind of pine beetle - presumably black turpentine beetle - on eastern Long Island. These trees had suffered injury from salt spray during superstorm Sandy.

There are wetland permitting issues involved, and so we need to revegetate to keep everyone happy. Our original thought was to plant some oaks suitable for the site as we feared the beetles in the area would kill any pitch pines we planted. However we were told that we should replant "in-kind," and that the new, healthy seedlings would not be bothered by the beetles.

Any input would be welcome.

Another point of view.

The beetles usually only attack trees that are compromised healthwise. They don't generally attack small trees. By the time the trees are large enough to attack, the beetles will have moved on, looking for new food sources, and the trees are going to be no more susceptible than any others. The trees should be kept healthy; the healthier the trees, the less likely they will be attacked.

If you were allowed, planting deciduous trees would be good, but in the situation you're in, planting new pines will be fine.

Turpentine beetleI don't think that replanting plants that have got a community of insects feeding off of them would be a good idea. Granted the storm weakened them, but healthy plants are going to be feeding the beetle larvae that have found the original pines. I'd find a good indigenous tree that hasn't had any problems with insects, now or in the past. Amelanchier alnifolia (Serviceberry) is one I can't believe hasn't been planted more. It's a great understory plant that won't be bothered by a little shade while the remaining pines return. Oaks have had many problems, be careful which variety you choose.

I looked up a few sites and planting new pines (Rigida or Pitch, Scot Pine or Japanese Black Pine) is not a good idea. When insect populations go up they will attack healthy pines. Unless you want to baby the new trees with pesticides, just plant non-pine indigenous stuff. I am sure they should have a list of recommendations at your extension service in your state.

Replanting trees in this environment will likely result in weakened plants and simply feed the insect population. As J. Musser above mentions, establishing a base of hardy shrubbery is necessary first.
