It's not any one thing for me, but deep at it's core I love and have a passion for 2 things that drive habitat improvement for me. The first is the obvious love of the outdoors, don't need to go more into this, but anything that can get me outside, I'm all in. The second is a desire to tinker, improve and make better/bigger/faster/stronger. These 2 things melded into a degree in environmental engineering which I eventually turned into a career.
That career though results in a lot of desk time and plane rides/hotel stays. So my habitat time is the time I use to scratch that itch on my 40 acres. Time to be outside, to run a chainsaw, to plant, to mow to tinker... The end result is mainly for deer, but also making trails for the kids to hike, to attract turkey and squirrel and even some furbearers (not including Whiley haha).
I have an old fruit orchard that is mostly peaches, but some apple, plum and pear too. Even that is a lost cause to make any money on, but I still like to keep up what I can just as a habit of wanting to keep it looking nice and another excuse to be outside.
