Greetings, All, I have ten acres in the Seattle area, approximately three of which is pasture. I have a tractor (4500 lbs with loader and backhoe) that I need to be able to move around to various parts of the property, but doing so is difficult because there are enough trees (that I do not want to remove) that it is difficult to drive past them without infringing on their critical root zone. I have carefully plotted several paths that maximize the distance from the trees, however it still may be a bit too close to avoid damage. I'd like to learn how to remediate and/or mitigate -and possibly prevent- any such damage. The paths I've plotted keep me out form under any trees (i.e., I am outside of the drip lines), but if calculating critical root zone as a 1' radius per 1" DBH my paths enter outer reaches of CRZ of several trees (infringing by perhaps 15-20% of the CRZ). The affected trees are western hemlocks, western red cedars, douglas-firs, and bigleaf maples. If I am worrying needlessly, and this single path (quickly becoming a road) will not likely be problematic, please let me know. I will happily not worry about it if the consensus here is that damage will be limited. Or if some of those trees are unlikely to be bothered that would be useful to know, as I could alter my path to protect the more sensitive trees. If I do have cause for concern, how can I deal with the situation? Here are some ideas I have dreamed up: I could plan my incursions into various parts of the property so as to do all the work that needs done in bursts of activity, then loosen the ground where the tractor has compacted soil near a tree with a broadfork (or etc), adding mulch and/or wood chips. This is obviously inconvenient but I will do it if need be; there are only a handful of trees affected, so it can be done. My thinking is that it would un-compact the soil and introduce both air and material that would serve to amend the soil. I also considered that perhaps adding 6" of wood chips occasionally might limit damage in future by serving as a sort of cushion. I don't know if this would work, however, as it is fairly heavy for a compact tractor. What do y'all think? PS - Someone please let me know if I've posted this in the wrong forum.
