Its really going to depend on what the stand has in it already, how you do your harvest, and how the trees left grow in a certain amount of time. People can say “this tree will be this big in 10 more years,” well...maybe, maybe not. Who knows what kind of weather and stresses the trees may face in the next decade or more? There are certainly some general principles we can follow to give them the best opportunity that we can but then there is that very important component called Mother Nature and she doesn’t have to follow the rules we set.
You probably know this already based off the couple comments you have made but logging is ugly. My place right now looks like a tornado has come through and they arent finished lol. I see where some people say “make sure they clean up and remove your tops.” There are some loggers that will definitely do that if you want but keep in mind that IS going to affect what they pay you for the timber. The more you have them do the less you get but it may be worth it to you to get the place cleaned up. But, i do think you will also lose some habitat benefit if you do that though. Its all about what you want but have realistic expectations.
