Out Standing in Their Field(s)

Field work, as glorious as it may sound....

Does it sound glorious? (I've always wondered that!)

... isn't always a walk in the park. In fact, that's usually what field work is NOT. I thought I'd share with you a few fun photos taken over the years and over different terrain. One theme I'd like to express - always make the best of everything. And be prepared for the worst!

One of the favorite pastimes of field biologists is the pursuit of a good locality for writing field notes. A well-formed rock outcrop can make my day!! (If you note the wind-swept look of the trees above and the bandanna covering my face, you'll have to pretend to understand what the photo can not show - its really windy there. One of the benefits of laying low is being out of the wind... so a nice seat, low to the ground, is a great find!).

The desert presents its own set of challenges - paramount is the grabbing of any shade to be had. To ignore such an opportunity is to be lazy. And who wants to be lazy when it comes to comfort seeking?

And... lest you think we professionals never slip up... I've got the proof!
Not to worry, we always carry a little shovel (and squares of wood AND metal plates called "Tow In A Box" AND tow straps. Yes, and we have used them all through the years!). This road was just graded, so when we pulled off on the side to check out some stuff... the car didn't have much luck with the soft, moist berm. We got outta that one fast.

Because I get paid to hike doesn't mean I'm always very graceful about it! Sometimes the best way to get down a steep, talus-ey outcrop is to use yer head. Which means using yer @ss!

By the way, the rock-hugging green and red plant behind me is the urn-flowered alum root (Heuchera elegans), a California rare plant. In part, it is because the plant grows in a very limited geographic location. In part - it doesn't get reported often since it grows on steep, talusey slopes - places were most people don't find themselves sliding around on their @sses...

Getting that perfect shot is not a glamorous job at all; but we gotta do what it takes!


(yes, I do realize this pic actually displays my @ss even more prominently than the previous...)



And never miss a photo opportunity with an old, rusted out car!


Well... maybe not EVERY opportunity...


(thanks to my cousin, M, for the photo!)


Bye y'all!

Photos of Wildflowers From Over 2 Months Ago

My, how time flies! And we've been very busy. Lots and lots of work this year. This is good, since its been a pretty decent rain-year, and therefore many native plants have sprouted and flowered. Here are more photos of wildflowers from one of our work sites on the north end of the Antelope Valley (that's the same valley where the famous Antelope Valley Poppy Preserve is located). I took these photos over 2 months ago, and I'm finally finding the time to post them for you. And, rest assured, I have been snapping many more great shots in the mean-time!




We were working in an area that was composed of soils with lots of clays. Many of the California Floristic Region flowers love these soils, such as California Goldfields (Lasthenia californica), the little yellow flowers in the photos here.


Another amazing clay-loving flower that we found was the Mariposa lily (Calochortus kennedyi). Brilliant! Being a bulb, this plant appears to prefer tough-to-dig clay soils so that digging mammals like gophers cannot eat their succulent underground flesh. I tried to take a photo that could impress upon everyone the awesome display that these lilies form. There's a flowering lily about every 10 feet in some areas. Unfortunately, cheap digital cameras just can't capture the subtlety and drama of this flower.

And another clay lover - a little onion, Allium denticulatum. This little onion absolutely covers the ground in some areas. These photos only partially capture the magic of being amongst a field of blooming onions. Oh, and they bloom for a couple weeks, and are gone. Like the goldfields, the mariposa lily, and all other desert annuals. They are but brief visitors to our world!

Scaley Skins

We were working out in a valley in the Mojave Desert called Johnson Valley. Many people know of it because they ride motorcycles and other ORVs out there. We were there looking for rare plants. When walking, you see a whole other world. The slow side of the desert.

Amongst some rocky outcrops, we saw the rocky-outcrop-dweller, the common chuckwalla (Sauromalus obesus). This one is a male because it lacks dark cross bands on its back. Chuckwallas are a fun lizard. They're big, bold, and curious. Makes for easy viewing.

Next, we found this desert horned lizard (Phrynosoma platyrhinos). Doesn't it look prehistoric?!? In this first photo, we posed the lizard. That way you can get a good look at its head and flat body. The flat, round (pancake-like) body is why they're also called horney toads... but they are reptiles, not amphibians.

The desert horney toads come in a variety of colors, which generally seem to camouflage with their backgrounds. This fellow had a strong red and black coloring to it, which perfectly matched the red and black lava rocks in its immediate locality. Pretty cool! Do you see the lizard in the photo to the right? Yup, right there in the center. This way, predators like roadrunners can't find them as easily.

And finally... my favorite photo of the day - a Mojave green rattlesnake (Crotalus scutulatus)! And I took this particular photo! (Usually the hubby takes the close up photos of the rattlesnakes.) This is the very first Mojave green I've seen. I've wanted to see them ... I've seen the Pacific rattler, the Panamint rattler, and the sidewinder. Now the Mojave. By the way, this is the most-common rattlesnake to bite, and it has the worst bite of all of them. Seems the juveniles aren't good at biting out the proper dosage and often overdose the victim on venom. Not good! Oh, and, by the way, this particular rattler was a youngster, told by the fact that it wasn't really very green (or so I've been told by those who know).

This leads to my farewell joke. Possibly my favorite within the Redneck genre: You know you're a redneck when your final living words are... ..."Hey guys, watch this!"

Spring Update

Busy busy busy!! And we just can't avoid that wind. Guess that's life.

I've been seeing the baby Costa's hummingbirds and they are very entertaining. One (some?) of them sits on the hummer feeder attached to the edge of the kitchen window sill and stares at me (washing dishes) for several minutes at a time. Intense staring. For a hummer to stand still for 30 seconds is rare. Several minutes is unusual - this tells me it must be one of the babies of this year, and its learning its environment. I do believe that this hummer is one of the babies. Its difficult to see in the photo, but it *is* smaller than the other Costa's adults. Its also a little duller and fuzzier.

We've also seen some Anna's hummers, which are unusual here (they occur more towards the coast) they usually leave by the heat of the summer. I like them because their gorgets are red.

The desert iguanas are starting to emerge... which means the heat of the summer is arriving!

I also wanted to share this photo. It is looking south, across the Antelope Valley, to the California Poppy Preserve. See that orange?? Those are the California poppies!! We're so close, and yet so far... At least I can share several other poppies that I've seen this spring. To the right is the small-flowered poppy (Eschscholzia minutiflora). The flower is much much smaller (desert stuff is like that...).



And this is a prickly poppy (Argemone munita), which also occurs in the desert, but this one likes washes. You can see a rodent hole behind this poppy. Probably a desert kangaroo rat, one of the cutest rodents, ever! I've never seen one, only their huge burrow holes (I have seen the more-common Merriam's kangaroo rat (Dipodomys merriami), which even live in our yard). The desert k-rats must be big, because the holes are about 4 inches across. Kangaroo rats are not rats. In fact, they have cute tufted tails. They have large legs and hop around like kangaroos. Very cute.

Spring Critters in the Desert

We're supposed to be outdoors, working today... but there's a front coming through, and the winds are up. Not only that, but the project/area that we're in is associated with windmill farms (read: that place will be even windier than anywhere else). Now, since we're supposed to be experienced field workers, we've learned a thing or two about working in the wind => it sucks (and the hubby often ends up with a sinus infection). If we have to work with others and can't change the schedule, we're now experienced enough to dress for the weather. Here we are last year, when we were working in the same area, just a different project. A friend took the photo and called it "Desert Bandits" because everyone thought we were so silly to wear those face coverings... well, by the end of a month of working in the wind, a couple folks sheepishly whispered that they wished they had those face coverings!!

For this day, we were just scheduled to work with ourselves, so we opted out of the outdoors for the day. I consider it operating costs. You see, the desert, esp the Mojave is known for its wind. We're on the cusp between the California coast and the Great Basin inland. The temperature difference between these regions creates a huge pressure differential which, in turn, creates some pretty big winds. Hence the wind farms. Its a fact of the region, and if you're going to live amongst it, you learn not to deny its reality and its power (hence the wind farms!).

Today I'll share with you a couple fun critters that we found nearly a month ago. The high levels of rain that some regions of the desert recieved were great for much of the wildlife and plants. We've been experiencing chronic shortages of rainfall, and its creating stress on everything. Usually when we think of desert reptiles, we think of hard-scaled creatures like the desert tortoise and lizards. But, when conditions aren't as difficult - at night - there are other reptiles that make their appearances - such as this fellow, the western banded gecko (Coleonyx variegatus). Yes! A gecko in the desert! On the ground behind our friend you can see a shiny metal object. That's the discarded muffler which the gecko was found underneath (actually, it has a nice, humid burrow under the muffler, which provides its delicate skin even greater moisture in the harsh desert habitat). My coworker found the gecko. Personnally, I didn't expect anything. We were on the edges of a desert town and this was one of the offroad dumping spots where people love to discard old car parts, sofa's, etc. I was just annoyed. My coworker kept working - and found life! See, the desert isn't all that deserted.

Here's a "Where's Waldo" exercise for you. Look into this photo. Do you see anything other than rocks? Look into the center. See the round "rock"? That's a baby tortoise!! Talk about good camo! This leads me to another discussion. My brother was just visiting a couple months ago and asked me, "Why does every single road have fences alongside it?"... Yup. Its a myth of the West that there are wide open places. I mean, there are, but you first have to get through that barbed wire fence to get at it. Why is this?? Well... first off, consider that its private land and the person is trying to exclude others from getting on there - either to dump garbage, hunt on it, mine it, drive an off-road-vehicle (ORV), or graze their livestock.

Otherwise, a heck of a lot of land out here is public land - U.S. Bureau of Land Management land (yours and mine, but leased out for "Multiple Use"). Its those multiple uses that require the fencing. Don't forget that a mere 50+ years ago, everything was heavily grazed for livestock (cattle and sheep). Those animals aren't like our impression of horses - grazing on grass. They also subsist on eating shrubs... and in the west, they have to, because that's what they're grazed on. Recent laws put into effect by Pres. Bill Clinton right before he left office addressed the issue of grazing on public lands in the southwest, decreasing the number of livestock that can be grazed per acre on BLM land. Still, however, the land is grazed. You might not ever see a live animal out there, but believe me, the land is being grazed. They now just usually ship the sheep herds from location to location throughout the deserts. And if the sheep aren't there - wild horses and burros still are. I seldom see them, just their tracks.

In addition, we've still got major amounts of ORV riders, and the numbers increase daily. These folks are usually supposed to stay on trails and generally are not supposed to cross highways... but nothing is perfect. I know the fences are also supposed to restrict ORV's from crossing the road just anywhere. I'm sure its also road safety, so yahoo's don't run off the highway to do donuts out in some playa by the side of the road either.

But, most importantly (to me), a new trend for these fences is to keep desert tortoises from wandering onto the highways. I mean, a tortoise looks like a tank, but put that little fellow next to even a Geo Metro, and, well, there's no contest. The one time a Geo is a big car!! As a mitigation measure on many highway and utility corridor projects, the company is also now required to install tortoise-fences on these road-side barbed wire fences. A tortoise fence is just an 18-inch tall length of hardware cloth that is attached to the fencing and slightly buried (no tunneling beneath!). Tortoises are notorious wanderers and have often been observed near roads (in addition, road surface run-off generates larger plants just alongside roads, which is called an "attractive nuisance" that entices tortoises to be near roadsides). It is suspected that these fences are saving the lives of hundreds of these critically endangered species. Little "Waldo" shown above was found just a mere 1/4 mile from Interstate-15, a 6-lane highway that I have NEVER seen empty. Although Waldo is most-likely too young to wander, here is Waldo's buddy, Wally... found nearby and just 1/2 mile from I-15. There is no doubt in my mind that Wally's life is much much safer thanks to the efforts of people to have these fences installed and maintained.

Springtime Wildflowers

I'm baaack! After a long pause, I'm ready for posting again! This time I'm going to try to write less, and post more often. We'll see how that goes...
The desert and parts of SoCal have been great this spring! There were patchy rainstorms, and flowers are depending upon that. The eastern Mojave Desert got some great fall monsoonal rains and good cold winter rains. Here are some shots near Baker, CA. For those of you not in the know... the verticle line in middle of the second photo - that's the Baker thermometer, the largest thermometer in the world! Oh yeah.

This is a spot north of Barstow, CA. They got rain in some of the higher elevations. This may not look very floriforous, but its very impressive in-person.




Isn't this one great?!? This is near the windmill pass east of Los Angeles. Plants that live in drier regions develope spiney hairs to protect themselves from herbivores. This gives them a nice "soft light" when back-lit from the sun. This spot is pretty amazing... I was going to post photos of it last year as an example of one of the ugliest places I've ever worked... then we returned this year... and the high rainfall in the LA region germinated all the flowers! Well... okay, I think you just have to see this! Here's a photo from last September:

San Gabriel Mountains

We're working up in the Angeles National Forest these days. ANF is comprised of the San Gabriel Mountains, a fault-lifted zone just north of the San Fernando Valley (the Valley Girls valley just north of Las Angeles). Being in the mountains is nice this time of year... but don't be too jealous. These mountains are steep, covered mostly with chaparral, and rather hot and dry.

There are still some nice critters and plants to be found, however, and we're doing our best to discover them.













This is a sagebrush lizard, which is uncommon. The male has the bright red under his chin, either to attract females or to threaten other males (or maybe me?). Who knows?








The plants aren't doing so well this year, as I've mentioned (drought year), but we've found one particular species that's just booming: the Mt. Gleason paintbrush (Castilleja gleasonii). Yes, the paintbrush, everyone's favorite, known for its brilliant red blooms and long-lasting flowering duration. This species is doing particularly well because its getting a little help from its "friends". You see, the paintbrush is a hemiparasite, which means that it derives part of its nutrients from its chlorophyllus leaves, and part of its nutrients from another plant (to which its attaches by the roots). This plant is a Forest Service Special Status and California Rare plant, which makes it especially exciting to find so many of them.


Here's a view of some of the earliest-bloomers - the chamise shrubs within the chaparral. The white dot in the background (on top of the far ridgeline) is the Wilson's Observatory. Its a landmark for the San Fernando Valley, something they can see on those (occassional) clear days. Speaking of clear skies, we had some clear ones when we were working up there, and got some views of Los Angeles at night. It was strange to be camping, and to have city lights so bright along the horizon. They just went on and on and on...

Poppies for Steven

My friend Steven went to the Antelope Valley Poppy Preserve in search of the beautiful California poppy (Escholtzia californica), but, unfortunately for him, there hasn't been much rain out here and the poppy preserve wasn't much to behold...

Well, I was in the same valley recently, but in an area that had gotten just a little more rain, and a result - I got to see some poppies. Its not the same as seeing them in real life... but this will have to suffice for now:

Saved!!

What a lucky snake! Lucky for one thing that the driver at the wheel loves snakes. For another that the driver was alert to the possibility of snakes sunning themselves on the road and alert enough to swerve just in time to avoid it.



Can you see the tracks of the car which show how narrowly this fellow was missed?!?

And here's a close up of the lucky gopher snake (Pituophis catenifer), most likely unaware that it just stared death in the face. All it cares about now is that it has to stare at my camera...

Long-nosed leopard lizard



Here's a long-nosed leopard lizard (Gambelia wislizenii) that we found while working in the desert last week. Poor guy was pretty dehydrated and tired (there's a drought going on this year and everything is having a tough time of it).
I guess he was conserving his energy, I wasn't appearing to be much of a threat, so he let me get pretty close to him to take this picture. He even jumped up onto me as he was trying to catch some flies that were landing around us.

WindyDaysInSoCal










The hubby and I have been working in a beautiful area recently. Can't tell you where it is because that's confidential. If I tell you, well then I'd have to kill you. And we don't want that, do we??

You can't really understand the humor of the pic of the hubby unless you could also get the full effect of the wind that is whipping past us at the moment the photo was taken. The wind was probably up to a constant blustery flow of 60+ mph!!! I was getting pushed backwards at one point.

I think the pic of the oak gives a good impression of the force of the wind. Mighty! By the way, that's a blue oak (Quercus douglasii), which is one of the highly valued oaks down here in SoCal... just in case you were interested.
