Paleo Foraging

Paleo Foraging

Share

Wild edibles, Paleo tech, & herbalism backed by science & Indigenous history. Author of “Native Food Plants of Texas.”

I research uses of plants, animals, and minerals based on Indigenous ethnology, history, and archaeology. I started teaching foraging 12 years ago and have been foraging regularly for most of my life. My research will soon be a book available to the public. You can preview my research findings at paleoforaging.com. I have a professional and academic background in ethnobiology, botany, entomology, and ecology, including various research and teaching positions at both UT Austin and UC Berkeley.

The Many Uses of Buckbrush (Ceanothus)

Note that the Indigenous peoples mentioned are still living cultures and when I use past tense it is to describe practices in a historical context.

Insane poison ivy variant!

By “gestalt,” I mean you knowing it because of the way it is. You have successfully identified it so many times that you immediately know intuitively when you see it, without any conscious analysis of characters.

POISON IVY ID:
It usually has three leaflets, rarely five, even more rarely, one or two.

The leaves are bilaterally symmetrical, with a symmetrically lobed center leaflet, with the outer leaflets lobed more to the outside.

There is usually a reddish or pinkish tint to the petioles and petiolules, especially at junctures.

It is alternate branching.

Its adventitious (aerial) roots have a hair-like form and clasp the bark of host trees but also project outwards.

The bark has a slight yellow-orange hue with prominent lenticils (bumps).

The fruits are smooth, green to cream or white, small, and borne in large clusters that are somewhat pendulous (hang down).

USUAL VARIABLE CHARACTERS:
The leaves can be anywhere from highly glossy to matte. They tend to be glossy in the sun and matte in the shade.

They can be anywhere from unlobed to highly divided with almost serrate margins.

Leaf size also varies strongly, with leaflets only two inches long to leaflets ten inches long.

It can be a free-standing shrub, up to about 12 ft tall, a climbing vine reaching the canopy, or scandent (sprawling).

SPECIES
Toxicodendron radicans / eastern poison ivy is shown. These characters are consistent with all five Toxicodendron species in North America except for the leaflet count in T. vernix (poison sumac), which has 7-11 leaflets.

In the eastern US, in many areas, T. radicans, T. pubescens (Atlantic poison oak), and T. vernix are all present. In the western US, it’s mostly T. rydbergii (western poison ivy), except for the coastal states, which have T. diversilobum (Pacific poison oak).

T. pubescens can be distinguished from T. radicans by pubescence on its leaf underside, T. vernix by leaflet count, and the other two (T. rydbergii & T. pubescens) are identifiable simply by location.

Plantasia and Together for Big Bend have joined forces to protect the beauty of the Texas-Mexico riparian borderlands.

Join us this First Friday at 5:00 p.m. (June 5) in Lockhart for an evening of action and plant wisdom in support of Texas border communities. Whether you have family on the border, grew up there, or simply visit, your love for plants and the land makes a difference. Learn how to help!

Botanist Cyrus Harp (Paleoforaging) will discuss native plants and habitats at-risk of destruction by the border wall. We’ll contact our legislators and let them know how we feel about the wall with live postcard printing by Paloma Mayorga (Milpa Press). Friends and family of all ages are welcome!

Become immune to mosquitoes?!

Obviously, none of this has to do with mosquito-borne disease. I'm not suggesting anything for anyone, just speculating about my personal experience.

See my previous two reels (or YouTube video) for deterrence strategies, including those used by Indigenous peoples historically.
