I use to cut and skid for an Amish man that made a lot of money on Iowa walnuts, I've cut them in just about every county of Iowa, but now I hate walnuts, because just one walnut tree will waste more time than 100 white oaks. One of my personal examples below:
We are cutting skidding about 50-100 trees a day mostly red and white oaks and hickory. Life is good volume is good. Then we are told to shut down and have to meet with the land owner. We stop everything wait for the land owner and follow him to the far side of the property where we have never worked. He says he has a walnut that we have to negotiate over??????? So he walks us back along a powerline road on his place and points to a tree leaning over that some powerline guy says is a beautiful walnut. We look at the area of a little while from a distance and finally I speak up and I say, "What walnut?", landowner says, "That one leaning over." ....... I walk over to it, study the bark, study the leaves ............ "Uh, sir, this is a cottonwood just like these other 5-6 trees around it." things got a little tense after that, LOL. He thought I was lying, until I showed him it had that same bark and leaves as the other quite obvious cottonwood trees that were next to it. Finally we got to go back to work. Now we had been slaying 1,000's of board feet of veneer and grade white oaks a day, but this one walnut was going to make or break the deal for the landerowner, at this point, as a volume or production cutter and skidder I just hate them. Every walnut a landowner finds in a fence row with 5 strands of barbwire going through the middle of it requires an 1 hour conversation explaining why its less than worthless. They just drive me nuts.
Now if I'm paid to specifically cut walnuts then they are okay. We use to buy them in Iowa, Nebraska and Northern Missouri and Northern Illinois for $100-$800 per tree and mainly just bought, 10-70 trees per property. We sold the veneer and cut the lumber in a big amish saw mill. I got a nice percentage of the veneer and lumber profits, to own, move and operate the equipment and bonuses for finding and buying walnuts. It required a lot of hunting by road and even some pretty neat hunting techniques, but day in an day out, I'll take simple oaks and steady, drama-less volume over walnuts. I don't mind that I did it, but I wouldn't go back and do it again, I ended up breaking my leg riding bulls and leased out my equipment to them for about 1/2 a year and then brought back home and started working volume closer to home, much better for me and family.
The best walnuts are north of highway 70 running through Illinois and Missouri up into Iowa and Eastern Nebraska, there is a high population of them down around Joplin, but the landowners are all pretty savy to their worth and most every logger in that area has bugged them so much about them that they get pissed if you mention the word walnut to the landowners.
As to percentages the last contract that I saw the timber buyer make was 60% of the veneer goes to the landowner and 50% of grade goes to landowner and then landowner gets $100 per 1000 on the blocking. All parties seem to be happy with that arrangement.
