Part 3: Cover

During the past two weeks I’ve been addressing a question posted on my Facebook page. In those blogs, I discussed the importance of age and nutrition in managing land to yield mature, huntable bucks.

Area of cover for white tail deer

Next on my list of top 10 recommendations for managing land to yield mature, huntable whitetails is the need for cover. I define cover as areas where deer are likely to feel more secure compared to surrounding areas. In the Deep South cover may be shade, or in a colder climate native grass that serves to block the wind but allow the sun’s radiant energy to reach the deer. Cover may be areas where predator populations such as coyotes are reduced to be in balance with prey species.

Quality cover serves to reduce stress levels of deer and therefore allows them to express more of their antler growth and fawn producing potential. Cover can be just as beneficial to a deer herd as quality nutrition, depending on the sources of stress. However, one without the other means the deer herd likely won’t express its potential.

The best cover is not only a particular type of structure (shade, native grass, etc.), but also an area of reduced predation. Hunters are predators. To maximize the reduction of the level of stress it is best to combine the structure of cover while also making it a sanctuary (prohibit entry by humans during most of the year).

Sanctuaries are the least expensive form of cover to create. It simply means not entering an area. Sanctuaries with desirable cover are very beneficial to deer. To benefit the deer herd where you hunt, don’t just think about ways to attract them and make the deer easier to see, but think about managing enough of the habitat to insure each deer has a place where they believe they won’t be seen. This is not a totally unselfish act by hunters. Sanctuaries should result in a healthier herd, and one that is easier to hunt as deer that feel secure are not as alert.

My third recommendation for managing land to yield mature, huntable bucks is to create areas where they are “un-huntable” – create some sanctuaries!

Part 2: Nutrition

Last week I started addressing a question posted on my Facebook page about how to manage land to yield mature, huntable deer. The subject of that blog was how important age is to allowing bucks to express their antler growth potential. In addition, by allowing more bucks to mature, there will be more bucks to harvest – more bucks usually equates to better hunting.

However, there are lots of areas with a relatively high density of mature bucks, but very few bucks with good antler development. This often occurs in areas where hunting is not allowed and no habitat management activities occur. These areas include preserves, parks, etc. For bucks to express their genetic antler development potential, they must be allowed to 1) mature, 2) and have access to quality forage.

I remember visiting years ago with a wise gentleman when another person entered the conversation and shared an image of a very large buck recently harvested for that area. My friend instantly said “I bet that buck was harvested within a mile of one of the few soybean fields.” The gent with the image said “how’d you know?” My friend simply said, “All the big deer killed in this county are harvested by the soybean fields.”

My friend knew that big bucks are usually seen where the combines roam. His statement was not only correct for that county, but throughout the whitetails’ range. Compare the following maps. The first shows the distribution of soybeans grown throughout the continental states and the second shows the distribution of B&C and P&Y bucks harvested up to 2005. The correlation is not perfect, but it’s close enough to make the point.

The good news is that soil can be improved anywhere – even if the land you hunt is not shaded green on the soybean map. Notice that it’s a long way to any green on the map from where I live (Stone and Taney counties, MO). Even so, I grow great soybeans (and deer) using the combination of Eagle Seed beans, Antler Dirt fertilizer, and no-till drill techniques.

To have huntable mature bucks requires allowing bucks to mature and have access to good forage so they can express their antler growth potential. Good forage serves two purposes of allowing deer to express their potential and serving as an attractant so mature bucks can be patterned.

Insuring quality forage is available year round is #2 on my top 10 list of managing land to yield mature, huntable bucks.

Part 1: Age

Earlier this week I received a very good question on my Facebook page. Dan Dealy asked “Dr. Woods, what are your TOP TEN recommendations for managing land (and wildlife) to yield mature, huntable deer?”

One of the keys to Dan’s question was the second to last word –“huntable.” Most managers and hunters consider food, cover, and water, but they don’t consider how to make a property “huntable” or hunter friendly for mature bucks.

For a property to be huntable for mature bucks – for a hunter to have better than average odds of harvesting a mature buck – there are several factors that must be considered. To discuss all of these in detail would require a book (like Deer Management 101). In my next few blog posts, I will share some thoughts about my top ten recommendations to produce a huntable population of mature bucks. I apply these strategies and techniques to my property and have applied them to those of my clients for 20+ years. They are not deep secrets or magic recipes. They are proven and practical.

Having realistic expectations is the first step to satisfaction. It is important to understand that having huntable mature bucks doesn’t mean there will be Boone and Crocket class bucks behind every tree. A buck is mature to me when they are 4 years old or older. This is when bucks grow the largest antlers because most of their skeletal development is complete and they can use most of their excess resources to produce the biggest antlers of their genetic potential. Few free-ranging bucks express their genetic potential. In my opinion, many hunters, writers, etc., waste way too much time talking about whitetail genetics.

First, it’s very difficult to alter the gene pool of a free-ranging herd of whitetails. Second, there is probably nothing wrong with the genetics, but ample room for improvement of the habitat and herd structure.

With that said, my number one factor to improve the yield of huntable mature bucks is to have more mature bucks. To get more mature bucks, immature bucks must be passed and allowed to grow. Rule #1 the in Woods’ Book of Deer Management is that “Dead Deer Don’t Grow.” It sounds simple, but some hunters still don’t understand. They harvest a good looking two year old buck and then complain that they never harvest a “monster buck.” They’ve probably harvested several monster bucks – they just shot them before they matured and were allowed to express their genetic potential to produce large antlers! Bucks typically produce larger antlers as they age. University research shows that two and three year old bucks produce on average about 50 and 75% of their antler growth potential. It’s not until bucks mature to four years old that they express, on average, about 94% of their antler growth potential. To have an opportunity to harvest mature bucks, you must hunt where bucks are allowed to mature. That’s #1 in my top 10 recommendations for managing land to produce huntable mature bucks. The more bucks that are allowed to live to 4+ years of age, the easier it will be to harvest a mature buck. I’d much rather hunt a property that has three mature bucks per square mile than one or no mature bucks per square mile.

The least expensive form of deer management is trigger finger management. It simply costs less to pass immature bucks than any other form of management for establishing a hunter friendly population of mature bucks.

During 2012 – if you want to tag a mature buck, be prepared to pass immature bucks. Yes, others in your area may kill immature bucks. However, the trend must start somewhere and it is most likely to start with you. Share the education with other hunters in your area. You don’t have to convince all of them, but you won’t convince any of them when gathered around an immature buck you just harvested.

Remember, the first rule of deer management – “Dead Deer Don’t Grow.”

Ben Hampton, Prostaff on Midwest Whitetail, recently shared the pictures of this super buck with me. He found the buck’s sheds last year and they grossed 154 4/8 (172 4/8 with an 18′ spread) as a typical 6×6 and this year he grossed 174 3/8 as a 6×5, with an additional 10 non-typical points he didn’t have last year, for a total gross non-typical score of 191 6/8. Ben asked me if it was typical for a deer to make this big of jump between 5 and 6 and if the bad drought they experienced in the summer of 2010 could have suppressed last year’s rack.

Bucks, just like humans, are individuals. Some bucks produce larger antlers earlier than others. I was the tallest kid in 1st grade. Folks wanted me on their basketball team. By the time I was in high school, I didn’t make the team. Some bucks grow early, some mature late.

On average (averages represent populations – but almost never an individual) bucks express 94% of their antler growth potential by age 4.5. However, most wild deer don’t have access to quality forage year round. There have been bucks in research locations that barely scored 120 and then blew up to 200+ once given a better diet.

By being allowed to mature and having access to better forage created a perfect scenario for the buck Ben harvested to express his full antler potential. His timing was perfect.

So – in general, the better the year round forage, the later in life bucks will express their full antler growth potential.

Congratulations Ben, that’s a fabulous buck!
