  1. Giant Coast Redwoods ~ a Must-See ~ 2015

    Just updated a page about changes in this grove and new articles over the past year. Read more at: http://www.mdvaden.com/redwood_GOT.shtml

    I call this redwood "Gizmo" ...
  3. Tree Welding & Natural Grafts - The Magic of Myrtaceae

    Over 40 years working with trees and exploring forests, most examples of natural grafts I saw fit neither of those suggestions. When branches get close and trunks rub, it's understandable that cambium area tissue from both will merge into one mass cambium, producing a common mass of wood and bark. It's interesting that the question I quoted, is so far apart from the simplicity of what's happening. Grafts are generally not a common function like growing roots for anchor and nutrition or leaves growing to face the light. Grafts are more like coincidence, and not necessity. It's not impossible for a graft to reinforce a weak tree by bonding at a higher point. But it would be by chance and not by purpose or opportunity. To stretch for much beyond this simplicity would be like the articles the past couple years where writers were suggesting albino redwoods were saviors of the forest (when the opposite it true).

    "La Leche" ... Waited months to cross over for this photo. Water was too high in winter and spring.

  10. Decay Fungi and Trees - What Would You Like to Know?

    You spoke of the role of decay fungi in likelihood of failure. Actually, if wood is decayed, the role may not matter as much at a certain moment, as the fact the wood is decayed. But I think some relevant concerns may revolve around whether certain types of decay fungi can be identified and whether their presence is much bigger concern than other kinds of fungi. Are there ones that are no big deal, like what decays a small pruning cut area for a few years ... vs. another that means keeping a closer eye on the tree or justifying biting nails over. Is there a practical way to list the role of things, conditions practices that may commonly trigger different fungi? Or the worst of the decay fungi. I get the impression that it's common knowledge among experienced arborists that decayed or rotted wood tends to be weaker than "healthy" or sound wood. So it seems like decay fungi's "role" in likelihood of failure is not poorly understood.

    Colors of the Forest .... This shot will probably become a print or canvas ...
  12. Giant Coast Redwoods ~ a Must-See ~ 2015

    You're welcome. I live even closer now, so new photos can continue, with intermittent throwbacks. I haven't spotted #s on posts to reference back to yet, but back just a little to last month's June image of the wedding couple ... this spot below is where they got married, down on that small gravel and sand bar where the creek changes course ...
  13. Avatars

    I couldn't figure out where to change it to another new avatar tonight, and posted here asking. But I figured it out. Thanks.
  14. Giant Coast Redwoods ~ a Must-See ~ 2015

    For me, it's working very smoothly and speed is fine. I like the look of the new site too. So in a nutshell, very good. Thank you !! It was only awkward the first time because it was different. Once I got used to where to look for what, fairly simple.

    Fog is my favorite, but the redwood forest still looks dramatic under shade of canopies over 300 ft. tall, especially toward the last hours of daylight.
