- This video is a part of Conservation Strategy Fund's collection of environmental economic lessons and was made possible thanks to the support of the Gordon and Betty Moore Foundation and the Marcia Brady Tucker Foundation. This series is for individuals who want to learn - or review - the basic economics of conservation. The Forestry Economics series will look at what influences the decision of when to cut down a forest and the non-market values that should be considered to create an economically efficient system. This video looks at the factors involved in deciding when to harvest a given stand of trees and what the crop rotation period should be. Topics covered include stumpage value, growth rate, maximum sustainable revenue, average and incremental growth, and opportunity cost.

For Douglas fir in western Washington your analysis of costs would typically go, preparation of unit for planting, planting, meaning labor + seedings delivered to unit in good condition, one time aerial spray of broadleaf herbicide, aerial application of fertilizer, pre-commercial thin, fertilizer, commercial thin, fertilizer, clearcut unit. Fertilizer will vary in timing somewhat, application rate, and number of times, depending on site and growth. Those professional foresters need to make some decisions to earn their pay. How the timber company inserts road system maintenance costs into ROI timing depend on the firm.
The nursery unit that grows the seedlings may get the order four or five years in advance of planting, but is typically paid internally at sale to forestry unit.
This guy is a legend
These videos are amazing. Helping so much with my MA in Environmental Science. Crash course videos are also great. Thank you for your work :)
i wish i found this sooner. great video!
This video is great!
You got a new subscriber here. I find your explanation brilliant and cool. Thank you!
Awsome video .. thanks for creating such informative video for Forestry subject. Neglected in developing country.
this is really really informative. Thank you so much sir
Amazing.
thank you sir...
Very nice video, thanks!
Thank you for watching!
Thanks for this information! I'm new to this and find it very interesting. One question though; how does the relationship between everything within the forest biosphere impact growth rates? If you rotate cutting sections of forest, and assume it'll grow back all on its own with the help of all those animals and other plants, what happens to everything else once the forest is cut? How is that factored in? It seems forests are treated as things unto themselves, whereas they are living communities that are more than the sum of its parts.
Please upload videos on all topics of forestry
Yes please do...
It's really too bad that the Once-Ler didn't get a chance to see this video.
Nice video, though v.simplified. Some issues:
1) 7yr rotation, despite warning, will confuse new folks. Why not use 25-30yr lob softwood or 60-70yr hardwood?
2) Costs for planting, thinning, harvest, hunt lease and especially land. Land cost omission is how TIMO's market the =>10% returns while real returns of 3% are more realistic. IMO, land cost omission is probably your biggest lapse, here.
3) Taxes. LTCG, reforestry credit, step up on estate are all big factors in decisions.
Would you be willing to wait 25 to 70 years to get paid? Plus in a lot of situations you don't need such large trees. I sell firewood and every year i have a couple customers asking for the thickest pieces i have. I bring them the wood and autumn turns to winter, they call me up to split the pieces smaller. Go figure. Plus bigger trees are more difficult to fell and handle, especially if you have a rotation where they will damage the smaller regrowing trees.
@@user-bc3pc5gu2yIf unit is clearcut no one cares if some hemlock under the canopy is smashed. What the care about is mill set up for bigger logs. On the Gifford Pinchot some trees still go out that are bigger than 48” dbh, contrary to popular belief. The deal is the logging companies bid per the volume scaled. Big diameter, big volume. But at the mill that 48” log sells for less per volume than the 30” dbh log. The mill has to treat first couple cuts as special operation. The days of head saws being capable of cutting monster logs are gone, and the ain’t coming back.

This guy famously cut the first log at this mill, and the last log forty some years later.
Ahh.. the good old days when putting your money in the bank actually gives you interest lol
An arguable "high" 5% interest rate ($50 interest revenue ) from bank for saving $1000 instead of buying 250 sapling at $2.00. I'd rather buy 250 trees to plant , even at 10% interest ($100 lost interest revenue). Don't forget to deduct the income tax on the interest revenue -> 30% to 50% depending on your income tax bracket. for simplicity purposes ; $100 interest revenue a year x 30 years = 3,000$ (over time) . ONE Maple or Oak or Hickey tree (18 to 25 inch diamater ) after 30 years is worth how much? x that by 250 trees is how much? comparing planting trees to to interest is a no brainer.
Stop justifying my calculus class!!!
I lost him at hello OK so let's say we cut down a forest.....
