Great resource Lisa! Bookmarking this for sure. I can add a couple more, too.

Thanks, Kimberlie! I've added those links.

Posted by lisa281 over 2 years ago (Flag)

thanks lisa281 is there a way I can link/set a pointer to your article so I can retrieve this information from my favorites?

Posted by ronstephens over 2 years ago (Flag)

These are terrific!! Thanks for providing these resources.

Posted by txstack over 2 years ago (Flag)

@ronstephens Here's the way I'd do it, with the qualifier that my HTML skills are VERY limited:

Basic format: < a href="[link]">[text]< /a> [minus those extra spaces] So, the HTML would look like this, except I've added a space after each "< " to keep it from actually working:

< a href="">A Collection of Helpful Identification Guides< /a>

If you copy and paste the above, then remove the spaces after each " < " it should render a clickable link like this:

A Collection of Helpful Identification Guides

But an even simpler way is to just copy and paste the link from the top of this page into your own journal post, then describe it however you want. Or just bookmark it in your browser.

@beschwar Thought you might be interested in this, too.

Oh wow! Thanks for all of this work!

Posted by oceanicwilderness over 2 years ago (Flag)

@gnat79 - here's a list of resources you might find useful.

Posted by beschwar over 2 years ago (Flag)

Honored to be mentioned here! What a great list and idea. I have bookmarked and will be visiting often. Hoping to make a more inclusive and informational sumac guide soon, as I've learned much more since I created that video. I'll keep you updated :)

Posted by conboy over 2 years ago (Flag)

thanks @conboy - I'll be looking forward it!

Posted by lisa281 over 2 years ago (Flag)

Posted by lovebirder over 2 years ago (Flag)

Does anyone know of a post or website about Texas Oak trees? Looking for info on tricks to tell the species apart, not just red/white/live.

Posted by kimberlietx about 2 years ago (Flag)

These are the two that I use the most:
*SFASU DendrologyDetailed information on dozens of trees, plus many helpful resources for trees
Virginia Tech DendrologyAnother helpful tree resource

The Texas A&M site is also good and very user friendly:

Posted by lisa281 about 2 years ago (Flag)

FYI: The "Identify these sometimes difficult trees" journal post link no longer works. It's been moved from its original location to a new website:

The link is from @lanechaffin 's profile page.
There's also some useful info on the Texas Fraxinus species as well.

Posted by arnanthescout about 1 year ago (Flag)

Thanks, @arnanthescout! I fixed the link.

Posted by lisa281 about 1 year ago (Flag)

Hi @lisa281 !

@rymcdaniel 's created an amazing guide to the Callirhoe Poppymallows "A short guide to Callirhoe in Texas" at to help people better identify these commonly confused species. Would be a good idea to add that one to this list.

Posted by arnanthescout 9 months ago (Flag)

Also maybe add the Triodanis Quick Tips at
While @kimberlietx hasn't created a full key yet, I think it'll come in handy when it turns spring again ;)

Posted by arnanthescout 9 months ago (Flag)

@nomolosx has a great list of resources for hopper ID (auchenorrhyncha excluding cicadas) on his profile page.

Posted by caththalictroides 9 months ago (Flag)

I would like to swap mine on here with another one of my journal posts, please. I would advise against trying to follow the information in that post, even though they are straight from the Nearctic keys...
