Weekly Nature Question #2: What Species of Tree is This?

My Weekly Nature Question is about my asking for help from the blogosphere (and other internet users) to learn about species living in Angeles Forest and to share that learning with others.  I’m really hoping that this turns out to be a viable and meaningful way to share knowledge.

The answer to last week’s bird question turned out to be a White-breasted Nuthatch.  More information on this bird is now on it’s page in the Forest Life section of this blog and will be updated as new information is shared.

I’d like to extend thanks to:

Blogger gacochran of the blog Along The Way who first identified the species and blogger Westerner54 of the blog Off the Beaten Path: Hikes, Backpacks, and Travels for confirming the identification.

Although nobody sent me any further information, I did notice an excellent post from Sue of the blog Backyard Biology.  You can find a link to that post on the White-breasted Nuthatch page mentioned above or the reference page I created for her blog.

This Week’s Question:  What species of tree is this?

The sign in the photos indicates that the tree is dedicated to “Michael H. “Wally” Waldron for his untiring efforts for the Boy Scouts of America” and that the tree is “believed to be 1,500 years old.”  The sign doesn’t indicate the species, so I’m asking for your help.

  1. Hi, I promoted your blog on mine this morning. I get an email each time you publish, and thoroughly enjoy what you do. It’s the Blog of the Year award if you do such awards … but the value, I think, is that you get a (somewhat) broader exposure as I promote you to a wider audience. In any event, thanks for what you do!


    • Wow, thanks! Obviously it feels great to learn someone likes my work enough to promote it. I haven’t participated in past awards but I’m considering starting with this one. I just need to think through how to integrate it into my focus on the forest. Thanks again!


  2. My naturalist tells me that bristlecones don’t grow in southern California, so I don’t believe that is the right ID. Mt. Baden Powell is known for its Limber Pines, which is the correct identification..


  3. Dave called it. It’s a limber pine. For those who said bristlecone, that particular species grows at high elevations in the White Mountains on the east side of the Owens Valley.

    Limber pines bear a superficial resemblance to lodgepole pines, which share the same habitat and also attain similar, twisted shapes above 9,000′. The difference with the limber pine is that its branches are flexible, often so much so that one can tie them in a loose knot, hence the name. This adaptation allows the tree to shed heavy snow accumulations that tend to break off the branches of less flexible trees.


  4. I think that’s a Bristlecone Pine…they thrive only at high elevation, and are among the longest living organisms. The twisty roots are an indication…older trees often look less like trees and more like sculptures. I was lucky enough to visit an ancient grove this fall in the Inyo NF.
