Hurricane Effects on Desert Plant Life

These pages show the effects of the large quantity of rainfall from Hurricane Jimena which struck the central Baja California peninsula in September 2009. The first photos were taken about 3 weeks post-hurricane (Sep 27-Oct 8, 2009). A follow-up set of photos was taken for a number of the same scenes about 7-9 weeks after Jimena (Nov 22-Dec 4, 2009). Look for differences in the two sets in terms of the amount of vegetation and color.

Just a few photos from the northern range of the hurricane´s path, near El Volcán las Tres Vírgenes.

Tres Virgenes area

Road side with lots of annual grasses and beginning of perennials.

Near Vado Lester, Nov 2009

Not exactly the same scene, but very closeby. Nov 22. Jatropha cinerea and J. cuneata turning yellow.


The following set of photos were taken at the top of the final grade about a mile before the highway drops to the Gulf of California and into Santa Rosalía. The first row has a partial panorama from left to right. In Sep 2009, the hillsides in all directions were carpeted in yellow (mostly Pectis papposa) and green (small annual grasses like Bouteloua aristidoides and B. barbata). In December, the ground cover was all but dried up. The only obvious plant still in bloom was Allionia incarnata (Trailing windmills).

The following set of photos was taken just south of the Mulegé Pemex station in an extended dune field which is part of El Gallito point. In October, grasses (Cenchrus ciliare, Bouteloua barbata, B. aristidoides and Cenchrus palmeri) and Watson Amaranth (Amaranthus watsonii) tended to dominate. Other annual or perennial plants had sprouted and had some growth, but mostly had no flowers yet.

In late November, there was a large variety of plants in full bloom and many had well-developed fruit. Some of the species seen were: Tidestromia eliassoniana (Honeysweet), Euphorbia eriantha (Louse spurge), Euphorbia polycarpa (Sand spurge), Phaseolus filiformis (Slimjim pea), Trianthema portulacastrum (Horse purslane) and Proboscidea althaeifolia (Devil´s claw).

The following photos were taken in the Mulegé Valley, just out of town to about about 4 miles west of town.

Mulege Valley by Colonia El Ranchito

Agricultural fields in the Mulegé valley overtaken mainly by Amaranthus watsonii and Panicum antidotale. Oct 7.

Same fields Nov 29. A portion of the Amaranth has been cut down and livestock was grazing.

Same arroyo bank, Nov 29. Jatropha cinerea (Lomboy) already losing leaves and annual grasses dried up.

Mulege arroyo, Nov 2009

More or less the same view, Nov 29. Mainly note the dry grass on the other side of the arroyo.

Cucumber vines in Mulege valley, Oct 2009

Brandegea bigelovii and Echinopepon minimus (wild cucumber vines) along the arroyo bank, Oct 7.

Cucumbers in Mulege valley, Nov 2009

Unlike most of the plants in the valley which were getting drier, the cucumber vines, as well as Coyote melons, (see below) were actually more lush and growing like mad.

More topiary figures

More topiary figures. The red is Trianthema portulacastrum (Horse purslane) which is drying up.

Coyote melons

Coyote melons (Cucurbita cordata) vines. These plants were seen in large numbers. The vines, coming out from under trees and shrubs and crossing the ground looked like giant tentacles. Made me think of the utterly silly movie "Attack of the Killer Tomatoes". Yikes, watch out or the coyote melons will get you!

Cucumber vines crossing grassy field, Nov 2009

I was walking along with my head down, the sun in my eyes, when I saw these cucumber vines in front of me, crossing on top of the short annual grass species Bouteloua aristidoides. I took the photo then moved forward and turned to try a different angle.

Cucumber vine grotto, Mulege valley

With the sun out of my eyes, I looked up and to the right and saw this incredible site, a cucumber vine grotto.

Annual plants, Oct 2009

Annuals plants, Nov 2009

Same grasses in their pesky stage (when Bouteloua aristidoides earns its Spanish common name "Navajitas", or little knives). You´ll understand the name when you get them in your socks!
