I have been riding around looking at property and something
just jumped out at me one day! I sell a lot of timberland in west central
Georgia and after all being a ‘Registered Forester’ this topic is important to
me. Some trees look great, others, not so good. Some trees are straight,
few limbs and generally look good. Other properties have trees with lots of
cankers, lots of limbs, lots of sweep….you get the idea. I am sure you have noticed the same thing if you are interested in timberland. Let’s look at some
photographs.
Wild Trees - Notice the number of limbs
Wild Trees - Notice the sweep
Genetically Improved - Notice the straightness and lack of limbs!!
Generally speaking, the differences have to do with genetics.
Like the color of your eyes, height etc, trees characteristics are to a large
degree determined by genetics. Forest Genetics is the subdiscipline of genetics
concerned with genetic variation and inheritance in forest trees. There has been
lots of improvements in tree characteristics including: lack of limbs and the
ability to self prune, volume gain, straightness and taper and resistance to
fusiform rust.
Improved
trees are generally referred to as 1st Gen, 2nd Gen etc.
Let’s look at the differences.
1st Generation
– cuttings from superior wild trees. These trees generally experience
about a 10% gain over wild trees.
2nd Generation – best trees from 1st Generation were
crossed. These trees generally experience 10-20% over the 1st Generation.
3rd Generation – best trees from 2nd Gen were
crossed. Usually experience 10-20% gain over 2nd Generation.
A forest nursery man once explained to me that Seed Orchards are
open pollinated, which means you can identify the mother tree but the pollen
blows in so there is no way to control the father tree. You have probably
experienced your car covered up with that yellow pollen in the spring!
Tree improvement is moving in the direction of cloning which is
taking tissue from a tree and growing seedlings. One of the largest companies involved in
cloning tree seedlings is ArborGen.
OK, this blog was probably a little to scientific for most but
here is your take away…..Reforestation is EXPENSIVE and it is a long term investment.
If you are going to invest all that money is site preparation (such as spraying
herbicides), perhaps burning, then either hand planting or machine planting
your trees….then for heaven’s sake….USE THE BEST SEEDLINGS. Some trees are better suited to the piedmont, others are better suited for the coastal plain. Choose a genetically improved tree suited to your area!
