DA CRIME OF DECLINE: AN ARBORIST'S RAP

July 7 2016: Let's talk about decline. Not my own, but of trees. The #1 cause of tree decline and death in the urban/suburban environment is due to soil compaction. It's a slow and insidious process that can take years, in some cases, to manifest itself and often by the time it's noticed it's too late for meaningful corrective action.

I recently have personally experienced decline (again, not me personally, but my trees). Some Douglas firs that I have been parking trailers, trucks, cars, tractors, etc under their shady boughs for 16 years have been exhibiting signs of decline. Typical signs of decline, in conifers, due to soil compaction are loss of lower branches and dropping of interior needles leaving just the needles on the ends of branches. They slowly die from the bottom up and the inside out. It's interesting that deciduous trees generally have just the opposite progression of compaction symptoms - they die from the outside in (ends of branches drop leaves first) and the top down (branch dieback).

Here's how soil compaction works to debilitate a tree. As soil becomes compressed from the weight of something on top of it , like trailers, trucks, cars etc. it squeezes out and smashes the pore space through which roots grow. The roots of a tree must grow continually. If they cannot grow, they will die and as they die that affects the crown (what's aboveground) of the tree. As the crown dies, then there is less food produced to sustain remaining roots. It can be a slow deadly spiral. In conifers, such as my Douglas firs, by the time you notice the signs of compaction decline, the final demise of the tree occurs quickly, within a year or two.

I'm feeling distraught that not only do I have several large trees that I will have to remove but that as an arborist I did not have the foresight to foresee that before parking my fleet underneath them. Not bright. Ah, physician heal thyself. And so, I've become inspired to sensitize people to the dangers of compaction decline and since this is a big urban problem, I thought I'd go more urban with my message. I've written a rap song. It is my first and perhaps a little technically rough around the edges.

DA CRIME OF DECLINE

(Imagine a strong hip-hop beat in the background. Say similar to Snoop Dogg, 50 Cent, or Lawrence Welk)

I can see da forest, but I can't see my trees.
I doctor other people's, but not my tree's disease

Compaction is the action from which there's no retraction

It takes ages, man, to happen, while you freakin' or you chillin'
Your parking lot be real tight , but your trees you do be killin'

Compaction is the action from which there's no retraction

Them roots you cannot see, but they will not take a slammin'
The soil gets compacted and da roots be smashed and crammin'

Compaction is the action from which there's no retraction

My firs are losing needles and they're looking really dead
My homies in the wood see this, they'll think I lost street cred

Compaction is the action from which there's no retraction

Da crime of decline is messing wid my mind
I done the crime, I'll do the time, I wish I weren't so blind.

Compaction is the action from which there's no retraction

So listen fool to this golden rule
Don't park no wheels where the roots can feels . ... .it.

BOOYA!
