Default Redwood Roots



I am working on a creek restoration project in Oakland. There`s a path leading to the creek that goes up to and around a Redwood tree. From my observations, healthy redwoods have plenty of duff and supporting vegetation around the roots, but here the compacted path completely circles the tree. Moving the path and planting may not work. What are the consequences of leaving the path where it is now?</p>

Re: Redwood tree & path - Compaction around redwood roots is bad for the trees. A crucial question is, 'How much is the path used?' If it`s a path that was once used a lot, but is now used only occasionally, then it may be fine to leave the path where it is. If it is a heavily used path, then it might be better to move it. If it cannot be relocated and keep in mind that redwood roots extend quite a ways out from the trunk, so a new path would also compact the roots eventually, then you will just have to live with the knowledge that the compaction is impacting the health and lifespan of the tree. A really, really good idea would be a raised boardwalk instead of a dirt path. This strategy is often used in forests and wetlands where compaction of the soil must be minimized. Then you can plant forest native plants on the sides of the boardwalk. If the ground is compacted there, use colonizng understory plants like redwood violet, modesty and sword fern, planting out small sizes in the fall. Good luck, Lori Hubbart</p>

J, Another possibility would be to make sure that a thick layer of mulch is placed on the trail/pathway especially near the redwood. This cushions the impact of foot traffic, even heavy traffic`s effects are softened greatly. The benefit is it is less costly to install 6 inches of mulch and wood chips than to install a boardwalk which i happen to love the look of and the permanence of its solution and you do not have to move the path. The Downside is the muclh tends to break down over years and is moved away from the path way by hundreds of feet shuffling by. In short you would need to refill the chippings every year or so. Anyway, just another alternative. Best-Dan </p>
