I may have my dates wrong on this, but I’m close.
About 1993 they found a Viking dragon ship in the muck of
the bogs of Northern England.
Archeologists excavated it and did whatever they do to clean it all
up. But then somebody had the question,
where did it come from. So they started
looking and tried to figure out how to figure out where this Viking longship
came from. After floundering for months,
somebody came up with the bright idea to take a core sample from the keel of
the ship (because typically on a wooden ship, the keep is the singular larges
piece of lumber in its construction). So
they took the core sample and started studying the growth rings. By studying the growth rings they were able
to tell the weather patterns of the years during the trees growth (flood,
draught, fire, etc.). So once they
figured out the weather patterns they started looking around for another record
of weather dating back 800(?) years.
What they finally came to first start comparing to, was arctic snow/ ice
core samples. Comparing the two they
were able to identify the exact year which that tree was cut down in order to
make the keel. Continuing with the
fascination of the idea, they decided to see if they could find the forest used
to make the ship. They went around the
port, that became the bog the ship was found in and finally found a “forest” of
stumps buried a few feet underground a couple of miles away. So they started digging around and digging
up stumps and wouldn’t you know it, lo and behold they actually managed to find
the exact tree that became the keel. How
did they know it was the same tree? The
growth rings of course.
So they started
looking around at other trees of this forest and comparing it to other parts of
this longship and were able to identify several other parts back to specific
trees. Somewhere along during this the
forestry ministry of England heard about what they were doing and went and asked
them how accurate they could be. The
response was, they’ve been 98% accurate in identifying parts of the shop and
various other artifacts that they had found.
So the ministry came up with a great idea.
Now see there’s a little known problem around the world –
poaching – of trees. Some will call it
illegal logging, but it’s basically the definition of going into protected
lands and cutting down rare and endangered species of trees in order to sell
them from profit. But now we’re back to
the fingerprints. When you cut down a
tree you leave a stump. That stump has
growth rings, those growth rings are the trees fingerprint, and now we can find
and track the log. So this is just what
the English forestry ministry proposed.
What they proposed was simple, take a data base of the fingerprint/
growth ring of every log harvested.
Somehow, somebody in NATO thought this was a great idea. So around 2003 this became standard practice
for any responsible nation. Now, can we
catch the random little tribesmen in the jungle cutting down a tree? No.
Can we tell that a tree has been illegally harvested? Yes.
Can we track that illegally harvested tree back to its source? Absolutely.
At least as far as the first man who bought it. And he of course is the problem. So now we can lock him up and the villager or
tribesman can get a commission to legally harvest when and where
appropriate. Thereby protecting the
natural resources.
So I’m thinking this is going to be one huge database at
some point, with all of the gazillion trees cut down worldwide every year. But, it’s kind of a nice thought that in a
1000 years somebody will be able to find my table and track it down to the
forest that it started in. Hopefully
they’ll appreciate the work I’ve done.
