are lichens on your pear trees a concern?

What kind of lichen? Are they cutting out light/air movement or????

I have lots of lichen on fruit trees here but never found them to be a detriment. At one point I was convinced that they provided harboring places for insect pests, but observation revealed that birds where delighted to take care of that issue, and those trees with lichen have consistently performed as have those without.
So am curious about why you'd fool with getting them off/out. We do have different lichen here than down there, but the biggest differences are in the ground/rock dwellers (almost no umbilicarias here, for instance, and plenty more of 'red soldier' or 'British troop' types here, sometimes covering an acre or so). We have in trees many of the cup types and some of the 'beard' sorts, but they don't get as long as in the south, although I think that is as much because the wind rips them off as anything else; in areas protected from the wind they get fairly long.
