GBBD February,15th 2009

It's a gorgeous GBBD here in Austin, a balmy 67 right now but the temp is rising. We spent the morning putting Dromgoole's Rose Soil in our new rose beds that we laid out for Valentines Day.
I've got quite a few things blooming, nothing shocking or exciting...some things have bloomed all winter and thanks to Carol at May Dreams Gardens I'm realizing this for the first time!
Carol dreamed up this log-roll some time ago and garden bloggers from around the globe participate monthly on the 15th. Hop around and see what's blooming in your neck of the woods!

The bees were buzzing on this Upright Rosemary.
Purple Lantana has bloomed all winter...

My first Old Blush bloom of the season!

Unlike the upright, this prostrate Rosemary has bloomed all winter!

Salvia Greggii.

French Lavender, also a winter bloomer.

White Lantana

This Oxalis was blooming yesterday, but looked sleepy this morning.

Fringe flower


Some of my Arugala is sending up flowers, I think they are just so sweet:)


I know this isn't a bloom, but I was so excited to see the buds pop on my new Wonderful Pomegranate among the greens.

This is a houseplant, but I know the northerners count them, so I did:)

Dianthus, for some reason my little camera has a hard time with the bright reds and oranges...they always turn out fuzzy...anyone else have this problem?

Last months Loquat blooms, this months baby fruit:)

Little Kumquat buds


Carolina Jessamine blooming on the arbor, I just love the intensity of these flowers when most of the yard is dry and bare sticks...

Sweet little Four Nerve Daisy...they bloom whenever it rains, or I hit
'em with the hose. That's it for me here in Austin! I'm heading out to A&M for two days of plant talk so I gotta hit the road! Will check in on my favorite bloggers when I get back!
Happy Gardening!

CAMN Bus Trip

This is the fourth entry about the wonderful Capital Area Master Naturalist program that I am working my way through with a class of about 35 other nature enthusiasts. Last Saturday we spent the day with Geologist, humorist and teacher extraordinaire (if I could bottle this guy's enthusiasm I'd become an addict quick) Carter Keairns PHd. The day began at UT, we all parked and piled onto a lovely luxury bus for a trip around our fair city. I thought I was being plagued by allergies at the onset, but quickly realized that sickness was setting in. My memory of the day is slightly fuzzy...there was so much information to take in and a slow rising fever made it seem like a dream. So, thank goodness I had my camera as this will be more of a photo essay than story.

Look familiar? This is the view looking down while hiking up Mt. Bonnell
When I first moved to Austin, I would take every visitor here, and my energetic kiddo's if I needed to run them up and down the mountain to slow the sheer giddiness of little girls.

I hadn't been in about 7 years and was a little in shock by the development and radical wealth. It's amazing that another world lies just east of I35.

I had to put this shot in, just one of Carters expressions that I managed to catch more than any other look! He was so livid and engaging...people were joining our group because he demanded attention...not intentionally of course.


I can't tell you how many different maps of Texas we saw...from every age as far back as the story goes and has been interpreted by geologists. This was the beginning of what made this day seem unreal...Austin the former location of 11-12 ancient volcanoes...I had no idea!

There wasn't a moment of silence, the lecture continued from site to site...

Over Penny Backer Bridge looking south.
We didn't get out of the bus, but pulled up right next to this geological map of the ages...HWY360 cut through a hill...the yellow strip at the bottom, being the oldest layer is the Glen Rose Formation, going up from there is the Bull Creek Member, the Bee Cave Member, Cedar Park Member and on top the Edwards Formation...all representing time passing as the shallow ocean rose and fell.

We had a pit stop at Barton Springs and out came the maps to explain the magic of the Edwards Aquifer...we will be spending more time here on a future visit.
This map was amazing as it showed images from space through the times (computer generated of course) and Carter had outlined Texas in red to help clarify when and how the landmass looked when we (Texas) were underwater. The description made me think that I'd moved here a few million years too late...mmm a shallow clear warm ocean.
Next stop was Travis High School...what? I had no idea that Travis H.S. was on the edge of a preserve. How many times had I driven this road and missed this sign?

The gate was locked. That didn't phase our leader, who strolled up the road, found an exposed area and began the lesson in the street. What looks like dirt behind Carter here is actually chalk with a little settlement on top, so shallow that the kids had carved their names exposing the white lettering. Also embedded were tons, and I mean tons of fossils.

Chalk wall with fossils.
Part of the path looking toward St. Ed's in the distance.

Apparently the Admin. building at St. Ed's sits atop an ancient volcano...snicker, snicker...mumble mumble...hot air-heheheheh.

We finally hit the teachable moment that clearly explained it all...exposed layers of weathered limestone, indicating time when the clear shallow ocean was home to healthy algae, which remain as the calcium carbonate white layers, spaced between some 5 or 6 clear red volcanic layers! It's all coming alive now!


Just down this slope we looked back to see clearly what the cartoon picture explained.
You have to look carefully, but the red volcanic layer lies about an inch above the boulder at the bottom of the picture...

The next stop was in the middle of an empty field...what's going on here?

Meet Jon Brandt, soil expert with USDA-NRCWS Texas Soil Survey explaining...what is soil? The product of old rocks...naturally...but why such an ugly field? Well, this field is an example of vertisol...the most amazing breathable soil that is rich and self mulching, as it has the ability to expand and shrink slowly turning itself over...a builders nightmare, a gardeners dream. There are 12 types of soil in the world, vertisol comprises only 13 million acres...6 million in Texas...beautiful living soil!

Here's a plug of what this soil looks like deep down, chunky black gumbo...this time of year, just before our lovely rain earlier this week...the cracks in the soil were nearly an inch wide...but the bluebonnets were profuse in spite of the drought...you gotta love 'em!
One square meter of soil is the required amount for a thorough sampling. We were looking at a description of what we were standing on. Five factors explain soil, they are:
1. what is there? Parent material
2. living organisims, plants, animals, insects and microbes
3. climate/weather
4. landscape relief, topography
5. time.

Here we split into two groups for our exercise, which I had seen done several times now over the past few years of garden classes...where you take a handful of soil, add a squirt of water and work it into a ball, then you pinch a ribbon between your fingers, seeing how long it can get before it splits off and breaks... it's a pretty accurate account of the soil make-up...
sandy, loam, clay or silt.

Dove scat...why are they all together...probably nesting.
Deer scat, old and new...everywhere! The next class is on scat! Yea!
This is the last image I shot...the most obvious remains of the largest volcano...Pilots Knob. We didn't even get off the bus...this was as close as we could get because it's now privately owned. Apparently, this 79 million year old bump in the ground, give or take a million years on either side...is solid black basalt...just like the ocean floor.
The story of Austin beneith us is amazing. As I'm driving around town I'm drawn to the simple rise and fall of the landscape, and feel blessed to have a yard full of rich black gumbo...a pain in the butt sometimes, but what a marvelous story to tell!
I have to give a shout out to Carter and suggest that anyone living in the San Antonio area check out his class at UTSA, I'm sure it's hard as hell but man, you will learn! He's a master teacher...and not because of his education necessarily...he's that captivating. Way to go CAMN curriculum planners...we gotta keep him, and Jon both!
Happy Gardening!

CAMN at Commons Ford Ranch

Commons Ford Ranch House

I had to go over my notes from class this weekend because there were so many speakers and the information was so varied I needed to come to a clear understanding about how it all tied together...because, it always does. We met out at Commons Ford Ranch, a city park that was acquired in 1983. It's a 215 acre lakeside property boasting two short hiking trails: Waterfall Trail that is a fairly easy, unpaved 1.25 mile stroll and the slightly shorter Pecan Trail loop.

This impressive Live Oak stands just outside the 2500sq. ft Ranch House that is available to rent for special occasions. It was cold inside so someone lit a fire and we sat; 35 of us in a relatively small room gasping for air while trying to focus on the wonderful speakers. First up was Bill Carr, enthusiastic botanist with the Nature Conservancy of Texas who recently co-authored the field guide "Rare Plants of Texas" available at the Lady Bird Wildflower Center. According to recent surveys there are about 225 species or candidates for listing, as endangered, imperiled or declining plants in need of help. He came equipped with slides of a few that are located right here in Austin for us to try and find. New species are evolving and being discovered all the time as some are getting harder and harder to find. There are many reasons why a plant becomes scarce, weather being a main reason this year with low rainfall but also encroaching development
and invasive species crowding out the natives. I spent the time trying to sketch the flowers and take as many notes as possible about the seemingly endless list of diamonds in the rough. I'm most excited to learn about rare plants that are edible and medicinal and was tickled to find that I have one in my own yard! I can't wait for it to berry-out!

Next up we had MN Wallace Stapp '05 speak on his passion: The History of Master Naturalists in Texas, of which he has collected some 300 books on the subject and shared with us who he believed to be the most important and the most entertaining to read. He brought along some rare books for us to peruse and gave an open invitation to check out his findings! It was just the nudge for me to finally get into reading about the philosphers down at the rock outside Barton Springs.

Kevin "Fish-head" Hutchinson owner of Hill Country Flyfishers got us outside to breath some fresh air and took us down for our first hike and talk along the tributary of Lady Bird Lake to explain what a lifetime of being on the river has taught him about riparian life. "Fish-head," (I'm using that in a friendly way) Kevin, stands 6'4" and is probably the most conscious fisherman I've ever met...that says a lot, before you go wondering about the validity of my statement...I grew up on the Kenai River in Alaska and fished with my brothers and worked the canneries every summer from the time I was 15 until I went away my second year of college...I've caught, dip-netted, cleaned, smoked, baked, souffled and eaten my share of salmon and after I hiked the Resurrection Trail and saw them spawn by the hundreds, gave up eating them for many years. He pointed out with clear understanding what the naked eye might view as trash...broken trees and brush that may look unsightly but help slow things down in a flood and provide a safe haven for fish to bury their eggs and for invertebrates to hang out. He was a lively speaker with a booming voice, bursting character who clearly could fall on the other end of the political debate on preservation, but is able to see the whole picture. I can see why he's been in business so long, I'd go fishing with him in a minute...just to hear him wax on about how much he loves what he does and the world we live in. Man, was that walk n' talk mind clearing, and I got to learn about noodling...more than I think I ever wanted to know actually...

MN Patricia McGee, BCP guide

After lunch we heard Daniel Dietz speak briefly about the Balcones Canyonlands Preserves, he is the Environmental Conservation Information Specialist and he covered the history of the Preserve as well as volunteer opportunities...which are many! We then had the option of taking one of 3 separate hikes, which really annoyed me because I wanted to do them all and was forced to make a split decision! I wanted to take the Texas Trees in Winter walk lead by a certified forester with Austin Parks and Rec but ended up being swayed over to the hills hike because I was tired of sitting and needed to get some blood flowing...I'm happy to say that I enjoyed my walk with Patricia McGee, who has lived in the neighborhood for 8 years and she was very knowledgeable.

We started straight up the hillside, this is a view looking toward Lady Bird Lake which lies just beyond the trees.
Mostly a cedar forest, there was also Red Oak, Persimmon, Black Escarpment Cherry...which I have never seen with cherries and she told us of a place farther than we were going that had a few stellar Texas Madrones. The terrain was quite steep and the trees were growing at an angle, a little hard to see here.

I never tire of the forest, even in the middle of the winter, when most of the leaves are gone it's still magical.

Skat! Patricia was quick to identify it as fox. It was full of berries...where are those berries?

I've been falling in love with the clumping grasses and this gentle slope normally has a seep, but was dried up. The grasses look pretty good considering the drought.

We finally got to a lovely space where Patricia said she had never in her 8 years of hiking this trail seen dry...it was today, save a sweaty area under this rock sporting a few Maiden Fern fronds.

This is what was left of the Waterfall hike. A murky puddle, but you can see the floating fence that rises to accommodate rushing water but keeps the cattle out.

This is the view from the other direction...up stream...the water was only about 6 inches deep, on the left there is some pretty sticky mud. When we got back we had one speaker left, Krista McDermid of Zara Environmental LLC who spoke with us about the sensitive cave ecosystems around the world, and especially here in central Texas. Each speaker we listened told the story of our biodiversity dwindling in the fragile ecosystems of Texas down to the littlest flower, fish, insect or critter and what we can do to be part of securing their safety in a slowly disappearing wildscape. Another great class! I'm ready to go and hope you'll consider volunteering too, you don't have to be a Master Naturalist to count bugs or find plants just step lightly and have a good time!
Happy Gardening...and hiking!
