More Set B seedlings and Set A growth!
Monday 12th May, 2008
More Set B seedlings! Well, they might be. Else they might be weeds. We'll have to wait and see. Anyways, my father took all of these photographs on Saturday the 10th of May, a.k.a. Day 57 (Set B), a.k.a. Day 409 (Set A).
This might be a sweet chestnut seedling, the same one from the last post. In the four days between photos, it has grown another pair of leaves. Now that's progress!
This little chappy is almost definitely a downy birch. Notice that the seed coat is still attached to the left cotyledon!
This seedling is growing in the European beech section so it may well be one of them. But I have my reservations. This seedling has very narrow cotyledons, but beeches have extremely broad cotyledons, as illustrated by my photo in this post. By the way, the two coloured tubes bottom right are drinking straws used to mark the different species planting areas.
Back to Set A. Behold the treeblog king! Common alder No. 4. I just can't get over how amazing this seedling is. It's just... awesome. The whole top quarter is new height growth from just the last few weeks!
The Gamma Scots pine. A lovely straight stem on this one.
The Alpha Scots pine. Massive height growth so far this spring! You can see the thicker, lighter green portion of the stem is new. A little bit wiggly though.
A closer view of the rosette on top of the Alpha pine. They're kinda hard to make out, but just below the pot rim is a pair of 'horns', one on either side of the stem. I think these will develop into the first pair of branches. Excitement!

First Set B sighting? Possible sweet chestnut seedling
Tuesday 6th May, 2008
Yesterday, fifty-three days after I planted Set B, my sister noticed (and my father photographed) what I hope is the first seedling of the set. If it isn't a sneaky weed, this seedling should be a sweet chesnut. And it took a lot of effort to get hold of the sweet chestnuts! Let's hope that now the first seedling has broken through, the rest come thick and fast.

Set A super treeblog seedling update (Day 397): Part II
Saturday 3rd May, 2008
Brace yourself! Here comes Part II of Day 397's super treeblog seedling update! Part I looked at the common alders and Scots pines. Part II looks at the cider gums.
Cider gum No. 1, one of the smaller 'second class' cider gums. Check out the lateral branching halfway up the stem.
Cider gums Nos. 2 (left) and 5 (right). What, no lateral branching?
Cider gum No. 3: El Freak.
Cider gums Nos. 4 (left) and 6 (right). No. 6 is a complete midget! And No. 4 is sharing its pot with a cheeky moss.
Cider gums Nos. 7 (left) and 8 (right), two of the 'first class' cider gums that got upgraded to bigger pots. A little tall, a little bendy, but no lateral branches.
Cider gums Nos. 9 (left) and 14 (right). As above.
Cider gums Nos. 10 (left) and 12 (right). Both looking good from this angle, but No. 10 has lost a lot of lower leaves.
Cider gums Nos. 11 (left) and 15 (right), a couple of second class cider gums. No. 11 has weird-looking leaves and No. 15 is very small. At least it's survived though! I never thought it would live for long after being transplanted from the seed tray.
Cider gum No. 13. A kinky stem with a lot of lean but lots of lateral growth appearing. Interesting!
And now for some tragic news regarding one of the 'fake alder' seedlings...
Yes, the rumours are true. One of the seedlings appears to have given up the ghost. What a shame. The first death of a treeblog seedling by a cause other than predation. At least its partner in crime is still alive and kicking. I want this one to live long enough for me to make a positive identification.
As you can see, a lot of the cider gums, particularly the taller ones, have rather leany stems. Gustavo Iglesias of GIT Forestry Consulting, who has a blog called EUCALYPTOLOGICS, is a specialist in eucalypts - cider gum is a eucalyptus. He has recommended that I use something like a bamboo cane to straighten out the crooked stems. At the moment the stems are not lignified (barky) and so correction of form is possible - but this opportunity disappears with lignification, which ought to take place this growing season. So from now! Is this "cheating"? Maybe, but I want my cider gums to have good straight trunks!
P.S. The twenty-third Festival of the Trees is now up at 10,000 Birds.

Set A super treeblog seedling update (Day 397): Part I
Wednesday 30th April, 2008
Oh my. It appears I haven't posted a proper treeblog seedling update in a goodly while. I guess I ought to remedy that situation... with a super treeblog seedling update love explosion!!! This is only the second time all of the Set A seedlings have been featured in an update, so it's an event of some importance! The first STSU was way back when in December with photographs from Day 264 (see Part I and Part II). The photographs in this update were taken on Day 397 - Monday the 28th of April - by my father. Massive props to him!
The Alpha Scots pine. C'est magnifique! After an eternity of no apparent change in nature, the last month or so has seen this beaut get pumped! The green section of stem seems to have swelled in girth as well as grown taller... and at the top a rosette!
The rosette can be seen better from this angle.
It's Alpha's younger buddy, the Gamma Scots pine. Again, the green section of the stem is swollen with new growth. I expect big things from these two pines this growing season!
Common alder No. 1. While pathetic in comparison with the superlative No. 4, No. 1 is still a pleasant enough specimen.
Common alder No. 2. The runtiest of the runts. Looks healthy though.
Common alder No. 3. A slightly better performance places this seedling in common alder second place, ahead of No. 1 but behind...
Common alder No. 4! King of Set A! Absolutely incredible! I cannot praise this beast enough.
This photo has somehow sneaked into a Set A update... it shows the "pine needle or blade of grass" noticed in one of the Set B seed trays by my father on Saturday. I don't think that's a seedling, so, slightly worryingly, no Set B seedling has yet appeared above-soil.
And so ends Part I of this super treeblog seedling update. Come back soon for Part II, when it will be time to put the cider gums under the spotlight. And, to end on a bit of a cliffhanger... terrible news regarding one of the fake alder seedlings!

Duddingston Loch (26th April 2008)
Sunday 27th April, 2008
Being free at last from the bonds of dissertation, yesterday I took a walk in the sunny afternoon to Duddingston Loch, only about ten minutes from my flat.
The yellow sea of gorse covering the foot of Arthur's Seat near Samson's Ribs.
This willow grows at the bottom of a rocky slope, right on the shore of Duddingston Loch.
A few stunted hawthorns are growing on the rocky slope...
... and they are well advanced in putting out their new leaves relative to most deciduous species. Other early flusher I've noticed in Edinburgh include elder, gean, rowan, and certain silver birches and European beeches. The earliest flusher in town is probably the horse chestnut.
Oooh, look: a token lichen photograph! One of the hawthorns can be seen in the background.
Dead and living branches of the willow silhouetted against Sol.
Let's end with a stunning gorse photograph. Doesn't it make you long for summer?
treeblog Set B update (Day 44 - yesterday)
According to my father there are still no signs of life in the treeblog seed trays, except for something in the downy birch section that looks like a pine needle or blade of grass - probably a weed.

Atlas cedar cone
Friday 25th April, 2008
Sometime last week I saw a conifer with these big solid looking cones. I was intrigued and plucked one off the tree. Fairly light but rock hard with a nice scent.
But what kind of tree has these weird cones? The Atlas cedar (Cedrus libani var. atlantica)!
It is a native of the Atlas Mountains in Algeria and Morocco and is apparently one of the most planted decorative conifers in Britain. Which makes it all the more surprising that I've never noticed one before.

Common alder No. 4 update (Day 381)
Monday 14th April, 2008
Common alder No. 4 is flushing!
Doesn't it look great? After months of looking like little other than a stick, No. 4 finally puts out an explosion of greenery! The photos are courtesy of my father, who took them on Saturday (the 12th) - Day 381 for the Set A treeblog trees. There were four photographs altogether, each from a different angle, and I have cropped and stitched them together for your viewing pleasure.
Four times the greenery!
What about Set B? Well, as of yesterday (Day 30) there were still no reported sightings. Set A had seedlings by Day 30! But Set A was planted a fortnight later in March than Set B.

Ash at night, Edinburgh (10th April 2008)
Friday 11th April, 2008
The view from my bedroom window at about half an hour past midnight on the morning of April the 10th. Well, actually all I could see was blackness and a crescent moon, but this was a fifteen-second exposure. The tree in the centre is an ash (Fraxinus excelsior).

Silver birch provenance trials: satellite photos
Tuesday 8th April, 2008
Why hello there. This post harnesses the power of Google Maps to bring you satellite photographs of the Thetford (posts here and here) and Drummond Hill (post here) silver birch provenance trials I collected data from for my dissertation. If the little Maps windows below don't work in your browser, perhaps you'll have better luck on Google's own Maps pages for Thetford and Drummond Hill. Two things. One, the satellite photos are a few years old. Obviously older than the Thetford trial, created in 2003, which is not yet in existance according to the satellite images. And two, as for the Drummond Hill photos... well, the resolution is so low that you can't make out where exactly the trial is anyway.
See that triangle-shaped patchy area in the centre? Well, go there today and you'll find Thetford's silver birch provenance trial. I guess the sat image shows the previous land use, which I reckon was a Scots pine plantation.
See that dark patch with white stipes in the centre? Well that is the wood at Drummond Hill in which the birch provenance trial can be found. The really big black / very dark blue patch is Loch Tay.

Spring has arrived
Thursday 3rd April, 2008
At long last, the long months of winter are almost over and the long days of summer are just around the corner! In Edinburgh, today was easily the best day of the year so far. The morning was summer-warm with a lovely clear sky. Proper shorts and t-shirt weather. The buds on many of the city trees are in the process of opening; on a walk into town today I noticed rowans, an alder and many shrubby trees I didn't recognise starting to unfurl their new leaves. Out of my bedroom window I can see an elder with many new leaves and a cherry tree beginning to budburst (even some white floweryness). But the two big ashes aren't showing any signs of greenery just yet.
Back home, the deciduous treeblog trees are showing a bit of green. The following photos were taken by my father on Sunday (March 30th) - Day 368.
The magnificent common alder Number 4 is opening up its buds! And inside there are leaves!
Feast your eyes on this close up view of the unfurlage.
And then the two tricksy seedlings that I noticed in the alder seed tray at Christmas and have been calling common alders Numbers 6 and 7. Well, I said I had doubts about them, and look at those leaves. They are distinctly un-alderish. Actually, they don't look very birchy either, and I was thinking that's what they'd turn out to be. So at the moment, they're just mystery seedlings.
Here's a rare treat: a view of the full treeblog line-up. From left to right on the bottom row: Alpha Scots pine; Beta Scots pine; the mystery seedlings; cider gum No. 13; and cider gum No. 14. The seed trays at the back contain the Set B nuts and seeds - there was no sign of any seedling emergence in these trays on Sunday (Set B Day 16). Behind the Scots pines are five round pots containing cider gums Nos. 7, 8, 9, 10 and 12, and a square pot containing common alder No. 4. The small pots on the tray in the middle contain the rest of the cider gums and alders, and the fourth seed tray (centre right) contains non-treeblog lettuce seed.
