I talked about snags and their different stages of decomposition a while back. Now I'd like to go a bit more in depth on the subject.
First, let me say without offending anyone here, because there are many different skill levels among us on this forum when it comes to our felling fundamentals! Im not telling anyone what to do or how to do it. I'm simply offering advice and my opinions!
If you are just learning the basics and new to timber felling. I DO NOT! recommend trying to fell moderately to highly decomposed snags! It is always best to call someone with at the very least a decent amount of experience at it.
Especially it tight corridors of standing timber!!!
If you do chose to do so. I highly recommend having a friend or neighbor standing by at least a tree length away as a safety watch. Incase things go bad and someone gets hurt!
Now then. The two snags in this pic are in a fairly tight corridor of OG Spruce. Both are approximately 70 to 80 foot tall and about 18" to 20"on the stump.
View attachment 1014188View attachment 1014187The snag on the right is moderately decomposed with a limb locked top. The snag on the left is highly decomposed and free standing. However, neither are at the point of crumbling down, but either can easy break in half or loose their tops!
That being said. Never assume anything when dealing with decomposed snags! The core my be more sound than the outer ring of wood and vice versa, or the entire snag may be at an extremely severe stage of decomposition and ready to crumble! IMOP,
it is always best to do a standard bore test! If you're not familiar with bore testing? Then snag felling is out of your league! No offense!!!
When boring snags. Use little throttle and pressure when boring in. While at the same time KEEPING YOUR HEAD UP!!!. Trust me if the snag is highly decomposed. You won't need much of either! Often a bore test will tell you how safely it can be fell. If it feels like mulch and paper mache.
It is probably at the worst possible stage of decomposition and ready to crumble! Walk away! Smash it from a distance with a live bigger tree or use heavy equipment if possible. Of course this all depends on the size of the snag also. Now I know that lot of you don't have the luxury of using live timber or heavy equipment when doing tree removal for private land owners, If this is the case. I would suggest discussing your options with the land owner.
Let me say this again so there is no confusion!
Moderately decomposed snags can possibly be felled somewhat safely but are Stihl dangerous.
Severely decomposed snags can possibley be felled, but it can be very dangerous to do so.
Extremely decomposed snags are extremely dangerous to fall and will often crumble or break off the stump with no indications early into your first cut.
That being said. ALL SNAGS ARE DANGEROUS TO FALL! Regardless of the stage of decomposition.
When felling any snag in tight corridors or corridors at all, and when limb locked.
Always expect the unexpected! Stand by for the worst possible scenario!
Examples:
Tops breaking off the moment the snag starts to commit if the stag is limb locked.
Breaking off the stump due to rotten or punky holding wood. Resulting in loss of control of the fall.
Buckling in half with the top half coming back at you if the snag strikes another tree.
(This will most always happen in tight corridors if the snag breaks off the stump, so NEVER saw to fast! CUT SLOWLY!)
If you're removing several trees when clearing land and come across a limb locked snag. Most often it is best to just cripple the snag with a face cut, back cut and a big hinge and let it go with the tree that it is locked in.
However, always face and ONLY FACE the live tree first before crippling the snag so all the live tree needs is a back cut and ready to fell once the limb locked snag is crippled. Never spend more time under a crippled snag than necessary. Or any crippled timber for that matter!
Be completely aware of your surroundings. Think about what your going to do if the snag strikes this tree or that tree, and what direction it is most likely to buckle back if it dose strike any particular tree around you.
Never turn your back. Sometimes all you have to do is step to the side a few feet. Other times you may have to run like a bat out of H**L!
Have at least three escape paths planned out. Cut brush to do so if necessary. Remember, if you lose control of a snag or a live tree, Anything can happen!
Well gentleman. I haven't covered it all because I haven't experienced it all! Nobody has when it comes to timber felling, but I hope I made some since while covering some of the basics when it comes to felling snags!
So until next time....
Cut safe, stay sharp, and be aware!
