Tree Service in San Juan County, WA

Everything about tree work in the San Juans starts with a ferry reservation. Equipment that rolls onto a boat at Anacortes has to earn its place on the deck, and that one fact shapes how island tree work gets planned, priced and scheduled.

Thin Soil Over Hard Rock, in the Driest Corner of Western Washington

The islands sit in the Olympic rain shadow and get a fraction of the rain that falls on the Willapa Hills. Summer out here is a real drought, not a dry spell. Under that, the glaciers scraped the bedrock clean and left only a shallow mantle of soil across much of the county, so roots run sideways over stone instead of down into it.

Put those two together and you get most of what we are called about: crown dieback in Douglas fir that ran out of water in August, bark beetles moving into trees already weakened, and root plates holding far less ground than the size of the tree suggests. A fir standing on a few inches of soil over rock is a different tree than the same fir on valley loam, and it has to be judged differently.

Madrone and Garry Oak Do Not Behave Like Conifers

Pacific madrone is the tree people move here for and the one most often ruined by good intentions. It walls off decay poorly, resents root disturbance and construction traffic, and sunburns badly when a neighboring tree comes down and exposes bark that spent forty years in shade. Sequencing matters — what you take first decides what survives.

Garry oak holds the remnant savanna ground on several of the islands, and those trees are almost always worth keeping. So are the shore pines and Rocky Mountain junipers out on the bluffs, which look scrubby and are often older than anything around them. Reduction, cabling and restraint serve all three better than a saw does.

Fire, and a Wind That Arrives From the Wrong Quarter

A dry August in the San Juans is a fire problem with limited backup. An island fire department cannot borrow ten engines from the next town over, which makes fuel reduction and defensible space around structures a practical local matter here rather than an eastern Washington concern.

Winter brings two different winds. There are the frontal southerlies every western Washington tree knows how to lean into, and then there is the cold northeasterly outflow that drains down the Fraser valley out of British Columbia and hits the northern islands from a quarter most of them have never braced for. Trees that spent their whole lives resisting the south wind are exactly the ones that come over in an outflow event, and they take fences, roofs and power lines with them.

Islands and Communities We Cover

Access decides more here than anywhere else we work. Narrow lanes, soft shoulders, gravel drives that will not carry a loaded chip truck, and long carries from the nearest place a machine can safely stand. We would rather ask hard questions about the driveway over the phone than find out from the deck of a ferry.

Ferry-served, plane-served and private-dock properties all work differently. Pick your island or town below for the local detail, or call and describe the access — that is usually the first thing that decides whether a job is workable at all.
