This has been an interesting thread to follow. Habitat, geographic region and topography of land prolly dictate one's efforts to improve property for deer. We've been at it since 2011. I had an interesting thought occur to me while reading some of the posts regarding TSI. Back when I started one of the 1st invites I gave was to the local head of forestry for the Georgia Forestry Commission. He was an older gentleman and has since retired and gone in to private practice as a consulting forester. At the time, our planted pines were 12 years old and pretty much completely canopied over. Very little sunlight hitting the forest floor but it sure was pretty to look at with all of the pine straw underneath. First thing I remember him telling me was my pine stand was a desert for wildlife, particularly deer as there was pretty much nothing to eat. Thus the reason we focused on other areas we could impact such as increasing size of food plots and doing light TSI in hardwoods.
What I remember most about his visit was this comment, "When you start seeing lots of rabbits you'll know you have good deer habitat". He said down south, rabbits are the canary in the coal mine in measuring quality deer habitat. A healthy rabbit population means plenty of browse and cover for deer...plus rabbits, quail and other critters. When we did a 5th row thinning of our pines in 2015 and 2016, we had an unbelievable explosion of flora growth... dog fennel, honeysuckle, beauty berry, blackberry, etc. Today we have rabbits everywhere and during mating season, you can't go on the property without hearing quail. And, we have more deer than we've ever had. So for all out there, regardless of location, that mention TSI as the big ticket item I think your spot on. In our neck of the woods it's mostly pine plantation management and fire that produces the needed cover and native browse. Following along Geo's future plans on Stone Branch, it looks like TSI will be his big ticket item as well.
