Ash are late

[stihlmadasever]

Seen a couple of ash just starting to leaf lastnight.

It's my understanding that it's due to the fact they are ring porous trees. My take on it, and I'm more than happy to be corrected, is that they spend the first part of the year laying down the vascular bundles they need and then set to work generating the energy they need to do the same for next near. It's the survival strategy of ash.

 

Ah, so they start growing before they come into leaf. I hadn't thought of that. That would explain it. Thanks.

All trees are opportunistic. They don't need much substrate to germinate in, and they're off. Pot luck though determined where the seed landed and if there's enough soil for it to grow in. A lot of other factors also come into play as well; seed viability, species characteristics, weather, mast year, seed eater numbers...

 

Jules, what's 'raid water uptake'. Is it what you Reivers take when you can't get our cows or sheep.

Umm, I really ought to proof read my postings. I thnk I meant 'rapid', but not as iteresting as your guess.

 

By opportunistic I mean Ash put out zillions of keys, not targeted, and whatever germinates can hunker down in poor light for years waiting for an opening in the woodland canopy, then they're off.

 

I have current first-hand knowledge of this. Out the back of my house, 20m from here, is a strip of land owned by the Council, until last year dominated by some 20-30m high Poplar. Last year the Council succcumbed to the residents' desparate please to have them removed. Now what is happening is tha thte understorey Ash and all its latest progeny are coming out of the ground at an unbelievable rate. Seedling density is about 50 per m2. Ash that are possibly 10 yearrs old but only a couple of metres high are goig straight up. Meantime the semi-mature stuff (5-7 m) that was at the centre and must have been very very shaded has just about died, I'm guessing a combination of too much light and too much water.

One or two with buds starting to open up here in the north east. Most barely showing even a bud.

Still a few sycamore not fully out either actually!

Although I suspect I'm much worse:blushing:

Point taken (again) Gary. I'm always in such a hurry.

When my Mrs points out errors in my typing I just remind her that I'm an arborist/arboriculturist, not a bloody typist.

Just been out on a pushbike ride and took this of an oak and an ash in a field where I stop off for a breather. There are lots of ash still looking like this it's quite usual round here.

Here's a stand of opportunistic ash. Shade removed and off they go. Just leafing up here in SW Scotland:
