Something a little fishy at the California Academy of Sciences

The California Academy of Sciences has been on my to-do list for about 8 years now and recently I was able to transfer that item to my to-done list. My fellow science nerd and great friend, Christal (of the Alcatraz swim) accompanied me up to San Francisco for the day's outing. She was keen to visit Claude the albino American Alligator.
The parking fairies favored me with free parking in a relatively close-by spot on John F Kennedy Drive between Music Concourse Drive and Conservatory Drive West.
A good spot to keep in mind if you are considering this science-nerd/child friendly excursion.

There's is a lot to see apart from biology/animal exhibits, but it was the animal exhibits that we enjoyed the most.

We had fun in the "Rain Forest" peering into glass boxes to spot the reptile or amphibian camouflaged against vegetation. The tiny orange "jelly bean" frogs went a long way towards curing me of my frog phobia. I could actually bear to watch them and would even go so far as to describe them as cute. Other bigger, greener frogs...not so much - they still made my skin crawl (sorry Kermit!)

We admired how well selected and put together the vegetation was too. That must be a fun job.

There were a couple of cocky parrots that spoke saying, "Hi there!" I thought it might be funny to teach them some swear words but thought better of it!

But it was the aquariums that stole the show.

Having done a fair bit of scuba diving in the past, I still love to watch coral communities, and their array of color never fails to amaze me!
The interactions and diversity is a real treat - we need to take care of these habitats and the California Academy of Sciences does a great job of raising awareness among the public.
Part of me wished I were in a wet-suit, listening to the hypnotic draw and gush of my breath through a regulator, suspended with perfect buoyancy control over this reef...just watching...
And yet another part of me was delighted to be standing in comfy clothes in a  perfectly climate controlled room watching this through glass!
How adorable is this little hermit crab in his funky tri-colored shell? And these guys....
One thing to watch out for is the signs that ask you not to take pictures.
 
I'll admit that I missed a few, but thought it okay because I made sure to have my flash turned off.
 
The colors were great anyways.
But I was a little confused when some signs said you couldn't take any pictures at all. Surely if the flash is off it's fine, right? So I asked a member of staff about it, and her answer was extremely enlightening.

Apparently many cameras, and even those on phones, use infra-red to detect light levels and focal distance to the object. Many of the deeper ocean species have sensors (like eyes) that are sensitive to and which can be damaged by infra-red. Many people don't know how to turn that feature off on their camera, some camera's you can't disable it, in fact, many even forget to turn off their flash, so for more sensitive creatures they ban photographs altogether.

At this point I was a bit worried. I confessed to her that I had only noticed some of the signs after I'd taken a picture (without flash but probably with infra-red), and apologized, feeling awful about it. Her attitude was that a small amount is probably fine, but if the creatures are exposed to lots of infra-red and flashes it will be a issue. This gorgeous Leafy Sea Dragon is one case where I think I'd noticed a sign after I'd done the dastardly deed!
I will be much more careful in the future. Since I'd taken the photos, I think I should share them but urge you not to do what I did. I'm still not sure which photos were okay to take and which weren't. Yes, there are signs but with all attention being drawn to the sea creatures, they can be hard to miss. Did I already mention - I feel terrible at putting the wee critters in harms way?

Maybe a blanket ban on photographs is what's needed. But at the touch tanks I asked permission from the staff present. This was before I'd even learned about the infrared, so I was trying to be careful! They said it was okay to take photos here as I petted the starfish - they feel kind of crusty, and not one bit slimy, as I'd imagined. I never touch anything when I'm scuba diving - you just never know when  you'll harm or be harmed!
Garden eels are one of my favorites from my scuba days, to such an extent that I've even got a scene in my new book that features them. So I was thrilled to see them.
When diving you need to keep really still. Any little movement makes them disappear into their holes. If you hang around they'll come back out in a few minutes. 

These guys were much less skittish and despite all the movement outside the tank they didn't disappear once.

I sure hope it's not because they've gone blind from all the photography!

California Wildfires Up-close and Personal!

It's been a brutal summer for fire-fighters in California. Huge wildfires up and down the state have wrecked havoc on people's lives and without the brave folk who fight and manage those fires there's no doubt that many more lives would have been lost and much more property destroyed.

Air quality in the San Francisco Bay Area has been the worst I've experienced in the eight years we've been here. The massive Soberanes Fire, just south of Carmel and 70 miles to the south of San Jose pumped out tonnes of smoke that were blown north getting trapped in the Santa Clara Valley. Even Hearst Castle was at risk at one stage when the fast moving Chimney Fire's flames licked to within 2 miles of the tourist attraction.

Meanwhile in Louisiana, massive flooding devastated the state this summer. Like all things in nature - enough water is valuable but too much is a disaster.

Surprisingly, the same can be said about wildfires. Not all wildfires are as destructive as those mentioned above. Wild fires are a natural phenomena in California that even aids native plant growth.

For the past few years, I've been very lucky to have been employed on a seasonal basis by Creekside Science, a conservation agency. One of the projects I help out with is population monitoring of the endangered Bay Checkerspot Butterfly in the hills east of San Jose. This is private land, and I consider it a privilege to get to go up there with the Creekside Staff, not to mention just how much fun they are and what a joy it is to work with them.

So I was concerned about my friends when I learned that here was a wildfire on that land. Upon checking in with my friend, she mentioned that she needed to go up have a look at it and I jumped at the opportunity to go with her.

It did look bleak with so much blackened vegetation.
The wildlife seemed very discombobulated. I nearly stood on a jack rabbit that had blended into the soil such that my foot was right over him when he decided to bolt, making me yelp and my buddy jump as a result of my yelp. Too fast for me to get photos off it, he wasn't the first animal we spotted, but unfortunately I didn't get pictures of those guys either.

Down in the valley, below a huge black boar/wild pig raced for non-existent cover. Not that he needed it, as his dark brown coloring helped him blend into the background.
We nearly took flight ourselves when a sharp hiss followed by an unearthly menacing rattle warned us to stay away from a very pissed off rattle snake. We didn't need to be asked twice as we took off at breakneck speed in the opposite direction from the two foot long reptile. I haven't have such a big dose of adrenaline in a very long time.

My feeble suggestion to go back, get a picture, was met with a raised eyebrow. I decided no.

On closer inspection, it was interesting to see how the fire had skipped over some places leaving patches of vegetation in swaths of blackened grass.
This is where the fire can benefit the California natives. It clears out all the (mostly non-native) plants such as grass. The natives, dormant and in seed at this time of year have more room to grow when the rains come and germinate the seeds. In fact, the fire even helps certain seeds to germinate.
In the pictures above and below you can see some native flower seed-heads that have escaped the burn. In the background of the photos below the green of the golf course looks so vibrant, yet ironically it is more harmful to the Bay Checkerspot Butterfly than the fire, because it disrupts their habitat and doesn't support the plants the Bay Checkerspot needs to feed on.

At first glance the fire seemed all consuming, but up close you could see that while the vegetation was scorched and burned, the soil wasn't. Here is where the caterpillars are hiding until the rainy season... waiting for their food sources to germinate and grow.
Monitoring the population next year will give us a better indication of the impact this fire may have had on the butterfly population up here.




Sadly, fire is understandably frightening for us humans. We stop it and in doing so that can actually cause more problems further down the line. In the case if this grassland fire, the methods needed to stop the fire are destructive for the local flora. Fire beaks, where the land is plowed up, destroy delicate habitat and mash up endangered species.

Fire retardant (red chemical dropped from the air) on serpentine rock provides the soil with high levels of phosphates which encourage the growth of non-native, often invasive, plants that choke out the native species, leaving the butterflies without food. You can see the reddened areas in the picture outside the fire zone.

By preventing fires in the past we've actually caused more problems for ourselves. A build up of undergrowth and unburned forest material means that the next time a fire hits its much fiercer that it might be naturally, so it burns hotter and damages more. Many of the recent big fires were caused by humans, but lightening can also start fires.

In California, fires will happen. Should we let them burn or not? Is it possible to manage them in a way that promotes harmony between us and the natural order? There are no simple straightforward answers to this. We humans need to live too. Figuring out how to do that, inflicting the least harm on our environment is one of our biggest challenges, but one we must address.

Even a grassland fire is scary to watch. A ferocious forest fire gobbling up mountainsides is terrifying. My heart goes out to the people in fires like the Rocky Fire in Clear Lake who have lost everything. My accolades go out to fire fighters everywhere for their courage and altruism and for showing us the best that humanity can be.

Bay Area Garden Railway Society and South County Railroaders Garden Railroad Tour

As a kid, I'd always fancied a train set. I asked Santa for one many times, but he never delivered. I guessed it was because I was a girl. I once broached the subject with My Father who told me that I'd been taken in by the ads on TV which showed the trains chuffing through cute little miniature villages.

"You're not interested in the trains," he said. "But the houses, and you don't actually get those with the train set -that's all extra."

As was often the case, my father had figured me out even before I'd figured me out!

I've always been enthralled by stories of miniature people such as The Borrowers by Mary Norton, Gulliver's Travels by Jonathan Swift and The Carpet People by Terry Pratchett. I've previously blogged about visiting a Miniatures museum in Taipei during our Taiwan trip.

So when I saw the Bay Area Garden Railway Society and South County Railroaders inviting folk to their Garden Railroad Tour to benefit the St Joseph's Center and Community Pantry, I talked My Husband into going - not that it took much effort - this appealed to both our nerdy selves!

This, I explained to him on the way down to Morgan Hill in the car, was something I had considered putting in our garden when I took out the lawn.

"Thank God, you didn't," he muttered. I thought the idea of the work and expense turned him off.

"Well, after the miniature murderer on CSI, " he admitted, "I think it would have been too creepy to have in our own yard."

Seems I'd lost that garden-design battle before I'd even tried! Still, he was happy to have a look at other folk's gardens and we were not disappointed.

We visited three different gardens - each one amazing, and different in it's own unique way. In all cases the attention to detail was amazing.

This one looked like a real town with everything to scale.
Of course, there was the trains - but My Father had been right - it was more about the scale than the locomotives for me.

My imagination plunged into this little town, making up scenarios and lives. Who ran the car lot? Was it a greasy salesman or the soul of the community?
 Good job they had a good fire department on hand.
 And was it hot for the man driving this cart as he waited to cross the railroad tracks? Was there a fold in the space-time continuum or simply a buggy enthusiast? Or a nearby Amish community?
 I'd like to live in this wee house.
 The "real" house in the background shows the contrast in scale.
"My" house was on the banks of an actual flowing (miniature) creek. I thought that this was incredibly cute.
 And nearby the dramas of life (and death) unfolded.
 Who was grieving for this person? How did they die?
 
Or maybe they'd been trampled to death by a random herd of bison!
Oh yes... the trains...nearly forgot! Maybe that how what had happened the deceased. Perhaps they too had forgotten while taking a stroll along the tracks and had been knocked down by a runaway train?
 What ever it was this RVer waited patiently for the train to pass. Maybe he'd heard the news...
In only very rare occasions was the scale a little out of whack - wouldn't want to come this close to a skunk this big if I were camping! Yikes!
 
Better to stick with the town and all its mod cons!
Each garden had a different feel. In this next one, the owner had spent time actually building structures to scale from scratch as opposed to buying scale model kits.
He explained how he had cut out each tile by hand before tiling the roof of the station.
 To My Husbands great excitement, these trains were all actual steam engines, although some had run out of steam by the time we'd arrived.

I felt like I had traveled back to the Wild West... 
 This beautiful bridge reminded me of the Tassagh Viaducts near Armagh.
 It was amazing how excited you could feel as the train chugged over the bridges...
... Or approached through the "forest!"
I enjoyed how he'd landscaped the natural vegetation to scale. This Rosemary looks like a huge sprawling oak tree!
At the third garden we visited, the steam engines were still vigorously clacking along the tracks. 
The emphasis here seemed to focus on the engineering of tunnels and bridges. A couple of "full time station masters" had a busy time making sure trains didn't collide or get stuck in one of the tunnels that was too small for most of the engines.
 
There were canyons...
And farms...

 And under bridges too...
 It was ridiculous how long I waited to get this shot of the train coming over the bridge and how pleased with myself I was when I got the exact shot I wanted!
 I waited here for a while too but gave up before the train came back! Patience is not my strength.
 And soon I was drifting back to the town...



 Admiring the vintage cars...
 When I heard the train in the tunnel and raced to get the money shot!
Oh what joy... but isn't great to take such pleasure in innocent pursuits!

Then I risked life and limb on the tracks, as this steam train bore down on me for the final shot!

Well done to the designers of all these gardens, and thank you for not only opening them up for us to have a fun day out, but in doing so to raise funds and hold a food drive for a very deserving cause - St Joseph's Center and Community Pantry.

As we drove home, I realized I no longer yearned for my own train set - that itch had been scratched and Dad had been right - I just wanted the cutesty villages. Now, I just create my own towns, when I write, and fill them with my own "living breathing" characters.
