Disturbance

When buildings, roads, and trails are built, the land is disturbed, and the soil is compacted or stirred up. Sometimes it’s simply unstable because of sands and wind erosion hits, or our cherished monsoon season rains sheet water downhill periodically.

But there’s a plant for that!

Speaking of sand, sand is on everything in my neighborhood and nearby trail areas. Mirabilis multiflora / Desert Four O’Clock and Ephedra aspera / Boundary Ephedra are here to help hold it in place. And the former attracts pollinators before the sun gets too high, so it can continue and expand its mission in life.

Bahia absinthifolia / Desert Bahia colonizes where someone probably drove over creosote bushes, leaving the soils bare.

And more weedy asters…daisies…opportunistic composites like moundy Gutierrezia microcephela / Threadleaf Snakeweed and whitish Zinnia acerosa / Desert Zinnia do the same across the jeep trail further down.

Have a landscape problem to solve?

Then look more closely to see which native plants respond to disturbance, not just neglect, and which don’t need irrigation life support to do it.
