How Can I Tell A Branch Is Actually Dead?
A few signs together are usually enough: no leaves while the rest of the canopy is green, bark that comes away almost without effort, and dry, pale wood underneath rather than the moist tone a living limb shows. Describe that combination over the phone and a rough read is often possible before anyone's even on site.
Is A Dead Limb Really That Dangerous?
Yes, more than most people give it credit for. A living branch bends with the wind and gives the load somewhere to go; a dead one has none of that flex left, so it lets go all at once instead of gradually, usually without warning.
Then picture where that falls - a shared fence, a parked car, the walk to somebody's front door on a lot with no room to spare - and "unsightly" stops being the operative word.
Does Deadwood Cluster Near The Ravine Edge?
It tends to. Decades of exposure to wind coming up off the valley leaves ravine-facing trees carrying more standing deadwood than a comparable tree further from the edge. On those lots, we check the permit question before we touch the branch, not after.
