Emerald Ash Borer is in CT

Have you noticed one of the 541 the purple boxes hanging from the trees throughout the state? They are traps to monitor the influx of the Emerald Ash Borer beetle in the state, and unfortunetly, they are starting to capture their prey.

The Connecticut DEEP announced the other day that the Emerald Ash Borer has arrived in Connecticut. This invasive insect has decimated ash trees to the south and west of this state, and is now poised, despite some of our best efforts, to do the same thing here. This is bigger than a business owner that relies on trees and trees health, this pests and ones like this are the first wave of a potential ecological disaster. I've seen first hand what pests like the Hemlock Woolly Adelgid have done in places like the Great Smokey Mountains, and we need to cut that off now, as soon as we can.

Get indignant - this isn't going to happen on my home turf. If you have ash trees in your care, get prepared. Do you have your weapons at the ready for this war? Be aware, be vigilent, be prepared.

Every zipline ends with a...

There is a home based zipline kit you can buy that has a note on top - it's the first thing you see when you open the box:

"Every zipline ends with a tree. Mind yours!"

That's good advice. I'd like to talk a little bit about the trees at the end of a zipline, or obstacle, or even your daughter's treehouse. The thing about a tree - any tree- that every builder has to remember is that a tree is not simply a large 10x10 plank or a telephone pole with bark on it. A tree is a living thing, and the safety of your structure is dependant on the tree remaining a living thing.

There are far too many "How-To" tree house books that attempt to explain the right way to built into a tree. And while the structures are viable, easy to construct and most likely safe, many of the designs I see completly fail to take into account the growth of the tree itself.

Remember elementray science - you can count how old a tree is by counting the rings inside it. Put another way, this means that trees add a new ring for every year of growth. So, that 4x4 beam you just nailed/lagged/bolted flush to trunk of the structure is going to retard the growth of the tree in the area of the board - where is the growth going to occur? A tree can compartamentalize and route around small damage, but if the damage is large enough you may very well end up with permanent damage to your main ground support.

I think this video shows what happens when tree based structures fail to take tree growth into account. I'm sure that when those eye bolts were added, the heads where on the outside of the limbs they were supposed to hold up (like in the picture on this post). See where they ended up in a few years time...
