Whether you take a very active land management approach, or are just starting to think about it, there are a number of strategies you can use to increase the yield of your hardwood stand. Here are four tips you should consider as you think about increasing your forest yield.
Volume and Value
When we talk about increasing yield, we need to consider volume and value. Let’s start with volume. Take any tree in a well managed forest and as you chart its growth, it will generally follow a typical bell shaped curve. We call this “mean annual increment” or MAI. Consider a red pine planted as a seedling. During those first few decades, it experiences a lot of growth. At around age 60, it starts slowing up on volume growth. The tree will continue to put growth on as it will typically live to 150+ yrs. old, but the volume growth per year will slow down.
Now, let’s look at this same red pine and take into consideration its value growth. Do you think that its value growth, or what I like to refer to as economic growth, is the same as MAI? That would be a somewhat typical assumption. The lion’s share of the time this is not the case though. As the tree grows in size and increases its merchantable volume, it also increases in grade.
Grow high quality trees
Seems like a no brainer, but there is a lot that goes into determining the quality of a tree. Trees are sold by product classes. Wood product classes are based on two major factors: defects and diameter. Our red pine example is generally classified as pulpwood, the lowest valued wood. If no defects are visible, then the diameter of the tree will determine what product class the tree falls into.

The town of Nahma Michigan is a very historic and unique lumber town located on Big Bay DeNoc Lake Michigan in Michigan’s Upper Peninsula. Isaac Stephenson was the first land looker in the area traveling from Oconto. He found enough timber with great river access to start a sawmill on the Sturgeon River. Sturgeon means Nahma in Chippewa. This was 1850 era. Land was purchased from the US government for $1.25/acre. As the years went by BayDeNoc Company built the town of Nahma and purchased many thousands of acres of land. They came north from Oconto (Oconto Company) after depleting the resource there. The company, now BayDeNoc Company, cut their first board in 1881 and had a great run until 1951, where again, the resource was depleted.
My wife and I purchased the old company hotel (Nahma Inn) in 2008. Two years later we bought the old general store mostly for storage, although there was quite a bit of old inventory from back in the days that sparked my interest. Excited to discover all the old items, I came across a box of what seemed to be paper that was going to get discarded. After further review I saw some color and writing. These were all the old company timber maps. Being a forester I was totally excited to see these. They are very accurate and depicted. There are a little over 200, each having their own section. Most were cruised 1895-1896. Each map and cruise was signed and dated by Webster Marble. Webster was a sought after forester and land looker back in the day. Webster put together a survival kit for foresters, trappers and anyone else that would spend countless days and nights out in the woods. The survival kit that Webster had put together took off like wildfire, in fact so much, he started a company to make these kits. This company is called Marble Arms, which is now based in Delta County. Their business makes highly collectable hatchets, knives and gun sights and are known globally.

In order to do our jobs well, we rely on a lot of different professionals while working in the woods. From loggers, haulers, excavators and more, we pride ourselves on working with some of the best in the business. Not only do great partners make our jobs a little easier, but they also help us meet our customer’s goals, which is our main priority when working in your woods.
In this Q&A, we get to know Rickert’s Excavating Company, based out of Birnamwood, WI. They provide logging and excavating services to individuals throughout Central and Northeastern Wisconsin. We’ve worked with them for over four years and are grateful to have such experienced loggers in the woods with us.
It’s no secret that tree cutting strategies play a big role in the log’s ultimate value. But unless you spend your days in the woods around loggers, you may not know some of the strategies we use to cut trees to their highest value. Here are a few examples:
This first image shows blocks that were cut from the end of the tree. By cutting these blocks, this particular log lost volume, however, its grade was improved. With that grade jump, the overall value of the log increased. Should the log have been cut shorter to begin with? It may have been miss cut because of the flair or bulge on the bottom left side of the butted piece. But by removing those blocks, even though volume was decreased, the grade improved, and consequently, its value.
Do you have a mandatory thinning or harvest due for your property enrolled in the MFL program? Could you benefit from talking to an experienced forester about managing your cut? We can help!
As a landowner, you no doubt have goals for your property. As experienced foresters, our team can ensure your land objectives and MFL program requirements are met. Whether increasing wildlife and recreational opportunities or creating income, utilizing a forester’s skills before, during and after a harvest can help ensure the health and productivity of your woodlot.
What can our team of foresters do for you?

This past summer our head forester Al Koeppel took to the woods with Kretz Forest Family member and landowner Jim Brandt to record a tour of his property. What transpired was hours worth of educational, and at times comical, video sharing land management strategies that have helped Jim and his wife Yvonne improve their 480 acre Shawano County property.
While each landowner has different goals, here is a short list of some common goals we often hear when talking with property owners:
• Wildlife management (attract or deter certain species)
• Improve recreational usage
• Increase timber production
• Safeguard property from disease and invasive species
• Create income opportunities
• Increase land value
This first video in our Brandt family property series gives a brief introduction to how Jim’s family acquired their property and talks about a few of the strategies Jim and Al have have used to improve wildlife habitat and produce higher quality hardwoods.
