I agree with what's been shared thus far. A few random thoughts I had, when hinging trees in the cold winter months, vs. warm weather, they tend to totally tear off the stump much more frequently in freezing weather, especially if hinging larger than 4" diameter, and when hinging higher off the ground. IMO if lack of sunlight is an issue for keeping hinged trees alive, it's time to consider logging. Logging is one of the best tools available for creating great deer habitat. Then, anytime 3 to 9 years after logging wade into the thick stuff and hinge the trash saplings that are undesirable for good timber and wildlife management. It's an interesting principle that good timber management often coincides with good wildlife management. Someone hinging trees in large quantities needs to be able to identify trees, and also have at least a rudimentary idea of what to cut and what to keep or they will be doing a lot of long term damage to their woods in a very short time. A great way for beginners to avoid this is too identify and mark all of the valuable trees, at proper spacings to allow for future growth without the crowns touching, then mark with orange ribbon, then hinge everything else in between.
