Weak habitat. Hmmmm. Interesting thought.
Habitat How-To Page
I'm always touting this page on the Kentucky F&W website, partly because I know the guy who wrote a lot of these pages and everything he told me to has helped my farm tremendously. However, give it a look-see. Wes gave me a lot of ideas that come down to what I would term "controlled neglect."
As a for instance: by mowing a wider margin around fencelines, you create instant habitat. Just getting lazy with the mower can have a huge dividend.
You might want to look at knocking over a few trees for browse/cover, strip disking a few patches of pasture to let the forbs grow, doing a controlled burn . . .
. . . or get the local wildlife biologist in to tell you what to do the way I did.
One thing I can tell you: There is a lot written these days regarding food plots. Food plots are expensive. I'm not going to say you shouldn't. However, I will way that food plots should be one of your later tactics.
Back in 2001, I got my farm and was all hot and heavy to do food plots. I bought $200 worth of seed, but the farmer who does my hay never came around to plant it. All it did was draw rats, sitting in the barn. Bummer. Long story short: I didn't get a food plot of any size in until 2007. It did draw deer, but not significantly more than the 6 years previous where I was doing things like letting my fencelines go wild.
