Can this be true ?

The bigger spread sheets and PDF file will not post here.  I cannot do more without your cooperation.

Don't cut and paste just read and type a half dozen pair of numbers. Diameter with it's height estimate.  It's too easy, that's it. ;) :D

[jim king]

This is the best I can do.  Here is only the second forestry inventory I have seen in the Peruvian Amazon were the people actually went into the jungle to make the inventory.  This is an unusual area of up to 06 meters above the high river mark that was to be made into a palm oil plantation about 25 years ago.  It was clear cut and has since returned to what looks like virgen jungle.  My wife and I lived there over three years.

This gives the dia. etc.  Maybe there is someone who can put this in columns as it was here.

Jim that throws the forum thread width out of whack. Might want to go back and remove all that.  :D The numbers look reasonable I guess for trees 11-15 m³. Looks like the upper height classes in the 30's got cut off though that would have those volumes. ;)

SwampDonkey:

Rather than pull some numbers out of the airfor a few trees here is a description of Purpleheart from a poor growing area.


Peltogyne spp.   
Family: Leguminosae   
 
Purpleheart
Amaranth

 
     






Other Common Names: Palo morado (Mexico), Morado (Panama, Venezuela), Tananeo (Columbia), Koroboreli (Guyana), Purperhart (Surinam), Amarante (French Guiana), Pau roxo, Guarabu (Brazil), Violetwood (English trade).



Distribution: Center of distribution in the north-middle part of the Brazilian Amazon region; combined range of all species from Mexico through Central America and southward to southern Brazil.



The Tree: Trees grow to heights of 170 ft with diameters to 4 ft, but usually 1.5 to 3 ft; boles are straight, cylindrical, and clear 60 to 90 ft above buttresses up to 12 ft. high.



The Wood:

General Characteristics: Heartwood brown when freshly cut becoming deep purple upon exposure, eventually turning to a dark brown sharply demarcated from the off-white sapwood.  Texture medium to fine; luster medium to high, variable; grain usually straight, sometimes wavy, roey, or irregular; without distinctive odor or taste.



Weight: Basic specific gravity (ovendry weight/green volume) varies with species from 0.67 to 0.91; air-dry density 50 to 66 pcf.



Mechanical Properties: (First set of data based on the 2-in.  standard; second on the 2-cm standard; third on the 1-in.  standard.)



Moisture content   Bending strength   Modulus of elasticity   Maximum crushing strength

            (%)                  (Psi)              (1,000 psi)                     (Psi)

Green (75)                   13,690                         2,000                  7,020

12%                             19,220                         2,270                10,320



Green (30)                   21,000                         2,560                  9,250

15%                                         26,700                 NA               12,200



12% (24)                     30,900                         3,460                14,500



Janka side hardness ranges from 1,860 lb to 3,920 lb at 12% moisture content.  Forest Products Laboratory toughness at 12% moisture content ranges from 157 to 398 in.-lb. (5/8-in.  specimen).



Drying and Shrinkage: Reports vary, from air-dries easily to moderately difficult; dries slowly to fairly rapidly; with almost no degrade to some warping and splitting Kiln schedule T6-D2 is suggested for 4/4 stock and T3-D1 for 8/4.  Shrinkage green to ovendry: radial 3.2%; tangential 6.1%; volumetric 9.9%.  Stability after manufacture or movement is rated as small.



Working Properties: Moderately difficult to work with either hand or machine tools, dulls cutters, exudes a gummy resin when heated by dull tools; slow feed rates and specially hardened cutters are suggested.  Turns smoothly, easy to glue, and takes finishes well.



Durability: Heartwood is rated as highly durable in resistance to attack by decay fungi; very resistant to dry-wood termites; but little resistance to marine borers.



Preservation: Heartwood is reported to be extremely resistant to impregnation with preservative oils; sapwood is permeable.



Uses: Turnery, marquetry, cabinets, fine furniture, parquet flooring, tool handles, heavy construction, shipbuilding, many specialty items (billiard cue butts, chemical vats, carving).

Yup, Jim makes perfect sense and plausible. 

After cogitation on an early assertion on the Sitka spruce, I had to do some editing. We were using 12.25 and 16 BAF's, with a 16 I was pulling in 6-8 trees in a sample. That means I could be within 31.25 meters of a 250 cm count tree. With some of the large cedar, if they were sitting in the right spot, they got counted 4 times on 50 meter grid. Took two 7.5 meter long diameter tapes to wrap around them. :D The cedar in the picture has some of it's girth to the left obscured by shade. You get a clue in the lower left of the trunk opposite of chest height, I'm there leaning in the middle. We had bigger ones on the flat land with salal vines all over. :

Now after researching this I have came across a lot of information about you guys up North and the carbon footprint you are leaving worse than Sasquatch.  We have to get into that next.  8) 8) 8)

[SwampDonkey]

Yeah, but one of them spruce was 48-55 m³ , 9-11 mbfm :D The carbon is stored a little further up in them sky scrapers. :D :D I remember a lot of those spruce sites where never logged, which is kinda of nice too because a whole lot of'm was cut before I got there on the BC coast. What saved a lot of them was terrain conditions mostly and critter considerations, which in the past didn't matter as much. Not that they couldn't be accessed, they had the machines to get at any timber, but it was the forest practices regulations that was the obstacle. ;)

Swampdonkey .. why dont you message him your email so he can send you the pdf file , then you can come back here and enlighten us with your findings ...

[SwampDonkey]

He showed me all I need to know. ;)
