So why do I need to involve a Forester anyway?
Excellent info on why to use a forester. If nothing else you will have a peace of mind that you didn't just flush thousands of dollars down the drain by hinge cutting valuable trees.
Paul,
Congratulations on your article published in Quality Whitetails!
Very nice.
HINGING
Hinging is the term used for the practice of partially cutting through a standing tree until the tree crown falls while leaving as much connective tissue intact as possible between stems portions above and below the cut. The objective of the practice is to develop quick cover while retaining a partially live crown resulting in a green brush pile. This is a useful tool for field edges, and when used in moderation and with knowledge aforethought, within the interior of woodlands. I have seen this practice misused so many times, though, that it makes me cringe. Believe me, any fool can buy a chainsaw and make a mess and this seems to happen most often when a landowner reads some magazine or other reference which refers to hinging as THE way to make cover. The real problem is that there is usually no foresight and little knowledge used when applying the practice.
Oftentimes, only a portion of the crown of a hinged tree remains alive because too small a percentage of tissue at the hinge remained intact and undamaged. Then only sprouts from the cut surface, bole and base of the tree remain. The sprouting capability of a tree stem decreases as it grows larger in diameter. The sprouting capability of a 3-inch diameter stem, for example, is roughly 3 times what it is for a 10-inch diameter stem of the same species. Also, sprouting vigor varies from one tree species to another. The sprouting properties of trees are used as a tool in some forestry applications. However, when sprouts are touted as browse material for deer, one important consideration is usually forgotten with hinge cuts, the sprouts will soon grow above browse height unless the deer concentration is exceedingly high and the number of hinge cuts is low. Once above browse height, the sprouts present a problem. Sure, theyre still making a mess but they soon grow into larger stems which serve little purpose for any wildlife species and adversely affect any desirable tree regeneration which may develop. Sprouts growing from the edge of a cut surface are weakly attached and as they grow in diameter they are increasingly prone to breaking off. Any portion of a crown which does remain alive usually declines over time. The lifespan of these damaged trees is shortened by disease and breakage and seed production is undependable. A site which has been laid waste to hinged trees resembles an early succession stand of young trees and shrubs (thick cover) but it is much less likely to succeed into a desirable stand with desirable tree species. It is also difficult to go back into the hinged site and correct the situation.
Timber stand improvement is the term used for a collection of woodland management practices used to alter a woodland for a multiple of landowner objectives. Thinning, crop tree release, weed tree removal, site preparation for natural regeneration and crop tree pruning are the t.s.i. practices most commonly used in southern Iowa. Application of some or all of these practices is the alternative to making just hinge cuts when quick cover is an objective. T.s.i. will result in a greater variety of groundcover, a thicker understory (cover) resulting from increased exposure to sunlight, increased regeneration of desired tree species, increased mast production for wildlife, reduced regeneration of undesirable species, and increased income potential. An example of a t.s.i. practice: Selectively release desirable species, e.g. white oak, black oak, by deadening competing trees of less desirable species. Some of the smaller competing trees and weed trees could be hinged during the dormant season while others could be felled during the growing season to provide some thick cover for bedding and turkey nesting the following season. The rest of the trees to be deadened, especially ones larger than 10 inches d.b.h., could be double-girdled or frilled and left standing to serve as snags for woodpeckers as well as other insect-foraging birds and for secondary nesters which use excavated woodpecker holes such as nuthatches, chickadees and flying squirrels. These activities still result in thick cover but the t.s.i.-treated stands, as opposed to hinged stands, will continue to develop into desirable stands. Timber stand improvement practices, when coupled with a multiple of objectives including wildlife, benefit a lot more species of wildlife than just deer and turkey.
Getting back to the subject of hinging, if you are going to make a hinge cut under any circumstance, be sure you know your tree species so that you retain those species which are of the greatest wildlife and commercial value. With that in mind, also be aware that a woodland with a good diversity of tree and shrub species is much more beneficial to a wide variety of both game and nongame species than one which is predominantly 2 or 3 tree species with a thin shrub understory. Dont target a tree species for reduction or elimination unless it is a problem species such as ironwood or black locust. I commonly see shagbark hickory deadened through a woodland because the landowner learned that hickories are worthless and that getting rid of hickory is the way to help out the oak resource. This rationale uses too broad a brush. Hickories serve a lot of wildlife species, too, though not so many as the oaks. Instead of targeting hickory in general, release oak crowns as they need it and make openings where less desirable species such as ash and elm dominate locations next to oak seed trees.
When making a hinge cut, the percent of stem circumference which remains intact will determine how much, if any, of the felled crown will remain alive. The greater the lean of the stem from a vertical plane, the greater the success because a greater percentage of the total circumference will remain intact and unruptured. The smaller the stem, the greater the success. Timing is important, too. The tree must be dormant. Mid to late winter is better than mid to late fall. Avoid making the cuts when the temperature is really cold because the tissue is more likely to fracture rather than bending at the hinge.
If you plan to hinge some trees along a woodland edge to favor upland game, consider a two-step approach. During the spring or summer before the winter in which youll do the hinging, identify the trees you plan to hinge. Identify where a trees crown will fall and then, using any glyphosate-based postemergent herbicide (e.g. Roundup, Cornerstone and others), spray an area at least 50% larger than the crown size. The resulting weed growth which will develop after the grass dies will be much more useful to quail and pheasant chicks than the dense grass cover would have been. Broadcasting some ladino or red clover seed into the sprayed areas would also benefit chicks because they require high-protein insects for early development and insects are attracted to legumes.

Congratulations as well on your published article. Also I showed the forester we use for the property in the thumb and he was glad to see the useful info here. Its alot easier for him to work with a well informed customer. That way he can understand the customers needs better, when they have an actual idea/understanding for what they really want to accomplish with their parcel.
After years of observation and hinging trees I have found only one bed under the trunk of a hinged tree while all others (depending on the slope) were backed up to the downed tree or laying above it (overlooking the downed tree)

You are absolutely right about this. A human would not feel very comfortable under a kitchen table, neither would a deer. Why would you ever try to create bedding cover that would make a deer fell like he was under a kitchen table?When confronted with danger deer must be able to leap to their feet and make a hasty and unimpeded escape, laying under something might be akin to us trying to escape from under the kitchen table....just food for thought but as always, make your own observations on your property and then make the habitat changes you feel will be most effective.... ;
I have seen literally hundreds of deer beds under overhanging trunks of hinged trees.

Those beds are also relatively close to the trunks of the hinged trees.![]()
Now, pull a kitchen chair up to that trampoline and try to eat off it:lol:. Thanks for making my point.
I have seen literally hundreds of deer beds under overhanging trunks of hinged trees. You simply have to do it at the correct height, in the correct location, with the correct orientation, and the correct structure. You are right though Paul, if you just randomly hinge trees you will seldom if ever see deer bedding under them.
These are examples where I am aiming the camera straight down at the impressions left in snow by deer. If you don't know how to do something, it does not mean that it cannot be done by others. I could go out and take many pictures like these on my 190 acres if I wanted to. Deer will lie under overhanging trees, in fact they far prefer it, but it has to be done with some care and effort.

One thing I have noticed in dbltree's photos is the relative openess of the bedding areas. In my neck of the woods it isn't typical for deer to bed in such an open area (especially during hunting season). The areas on my property where they bed it is typically thick and brushy.
That's the case here in S. MI as well. Beds in areas that open are usually evidence of night time bedding. Daytime bedding in areas that open is fairly rare, although I've seen exceptions to that on tracts that have large wooded areas that are completely unpressured.
Dbltree, I haven't looked at my QW yet. Looking forward to reading your article.
One thing I have noticed in dbltree's photos is the relative openess of the bedding areas.Paul points out a couple of key things deer look for when bedding, things that can be duplicated in specific places if you pay attention to the details.the following are beds I stumble upon while marking crop trees.
Another noteworthy thing to consider is that Paul's pics are winter pics in big timber. Deer will seek out spots of relative safety where they can lay in the sun during the day.
Given the option deer will seek bedding that provides EVERYTHING they desire. If a property hasn't had any TSI or hinging done I don't find it remarkable that they aren't bedding under overhanging trees, JMO.
I was on a property yesterday helping a fellow MSer with some cutting. Most of the timber was red maple (hint) and there were several beds present at the BASE of a hill NORTH of the beds.
