Backyard with lots of tree, what're my options?

I don't have a link, but I believe that if you send an owl to the Hogwarts School of Witchcraft & Wizardry, they may be able to help. I think they are in Scotland, near Hogsmeade. Unfortunately, Google Maps doesn't show a location, though they do have several locations for replicas of the Hogsmeade Rail Station.

I also have pool surrounded by lots and lots of trees. Honestly, its not that big of a deal to spend fifteen minutes netting the leaves out. I find that an electrically powered vacuum helps a lot in getting the stuff off the bottom without having to break out the real vacuum that attaches to the skimmer. I think there are cheaper ones that just hook up to a garden hose too.

Racker, to some pool owners the idea of spending 15 minutes a day vacuuming leaves is torturous; other folks enjoy doing it.

I personally dislike "crap myrtles" and "flaking birches" (river birch) intensely. Actually, I like river birches quite well, as long as they are not near a pool I service. Crap myrtles, I don't like anywhere.

But there are a variety of trees that are just plain bad around pools:
+ river birches (zillions of flaky seeds, that stop up skimmers and end up everywhere)
+ hickory family nut trees (bad stains from nuts)
+ crap myrtles (they are dumping SOMETHING in the pool, 360 days of 365)
+ cottonwood (who wants to swim in fuzz?)

Some people hate pines, because the needles pass the skimmer and pump strainers, and can end up clogging the pump impeller.

. . . And so on.
