Conifers and especially Cupressus

Sequoia

As I am new here, I think it could be ok to tell you what are my main interests.

Although living in Switzerland, I am caring about an arboretum dedicated to conifers in the South of France. It is not just to plant one tree of one species, but small groves. Several exotic trees planted in the region for timber are regenerating quite easily. After we experienced several dry Summers in a row, I am concentrating now on species adapted to that climate change, and especially on the genus Cupressus. I started a Cupressus Conservation Project after observing that some populations are under a constant threat in the wild. In the arboretum, many species adapted to drought are thriving.

I am always in need of help if anyone lives close to such populations of Cypresses or will travel close to them (photos, cones, seeds, report,...).

As I can see that there are several participants in this forum living in Australia. Unfortunately Australian conifers are difficult to grow in the arboretum. Or the Winter is too cold (-10?C), for instance for Callitris and Actinostrobus species, or the Summer is too dry, for instance for the Tasmanian conifers. So far I could only maintain an Athrotaxis selaginoides in the garden, where watering is always possible in Summer.

Best wishes,
Sequoia

Heres a good Cypress

OK, not many here.

Why do they suck so much those trees?

Who knows why I didn't photograph the largest Monterey cypress in Oregon this weekend - also one of the largest in the country. Here's a page about it (not it specifically, but its kind ) - just one of the first pages I glanced at..

eNature: FieldGuides: Species Detail

They seem to do marvelously over here, and the form is among the more interesting to look at.

As far as arboretums in general, I read an article about forests in the paper yesterday that had some interesting stuff about fires and plants. I'm going to condense the "highlights" to a few paragraphs on my forestry blog later today...

Forest and Forestry related page

I'm going to add extra comments with dates from now on.

Anyhow, a quick comment: the forest soil man, said that certain trees and shrubs help to fix nitrogen and are beneficial for other trees. I'm beginning to think that maybe a good thing for arboretums is to plant shrubs under imported trees, that are found under those trees. As long as they don't become invasive.

MDV, how tall is the biggest monterey in Oregon.
I took these two Macrocarpa down a few months ago, the tallest being 92 feet.

I'll see if I can find a full-tree image. There is one even wider by a foot in California, but have not seen it. For Oregon, go to this page...

Oregon.com - Oregon Coast Heritage Trees

Click on the Monterey cypress photo to get a bigger image. Note how large the trunk is compared to the table and chairs in front.

EDIT... Found a page with the feet....

ChampionTreesReport

Another page I found, says that a Mr. "Blake" planted the tree at his 1850s home there by Brookings, Oregon.

One golf course image shows trees very similar in form to the big ones on our coast...

http://www.golfclubatlas.com/images/CP17t.jpg

See golfers for size comparison. The branch / leader stucture near brookings looks almost the same, but is has more foliage out on the limbs and looks greener.

TREE-SURFER

The only real size comparison of the two trunks is this photo.The customer wanted all the trunk cut into rings. What a job.

Lots of cutting.

Tall, but the size of one big branch of the one in Brookings

TrevMcRev

Check out this Avenue of Monterey Cypress we cleaned up.





This one was a decent size



This one even bigger

Eric Frei

Look good to me, so why do people not like them?

Awesome pics again Trev I'd classify those as Significant Trees no doubt about it.

TREE-SURFER

They are just horrible to work with. You need to clean your saw with methylated spirits after cutting them. And they are just down right dangerous when they get any decent size to them, if there are any high winds in your area that has macro's, not very well rooted.

Oh yeah, the glue like sticky resin, that sucks.

Are they generally a messy tree that needs dead wooding and regular grooming?

nice job you must have the patience of a saint and the skin of a rhino to deadwood that row of Macro s

TrevMcRev

Ekka, they get full of interior deadwood, no real problem till you have to work on them though. When big, pretty common for major lateral branch & codom stem failures. Nearly all of em have had inappropriate pruning histories too. Everyone removes all the low stuff, usually done years ago by loppers so bad cuts, then the next layer of branches start to fail so take them off too. This continues till theres just foliage up high, then they get removed!

Not many people can do a good job of weight/ or crown reduction pruning on them without stuffing them up.

If they have the room, they are better left alone, all the branches kind of shelter and support each other and less likely to disintergrate like they do.

They do make good picket fences though

TrevMcRev

Yep and there were a heap more too. That job produced about 240m3 of mulch and we didnt remove a single tree.

All pruning

TREE-SURFER

I found, that in a tight crotch, or if there has been a trap of dead wood, all the shite builds up inside the crotch and the like and starts to rot away and cause infections. With all the stems that occur with Macro's, there is alot of inclusions also. Ive come across stones, gate pins and hinges, that have been lost in these tress over the years. Even the odd, well, alot of nails, that were hammered in by some guy's young great grand father when he visited his granddads shed and found a hammer and nails and just had to put them into something and the little tree at the bottom of the garden was ideal.
One section that was cut, had 7 included parts to it.

Camphor Laurels and Corals here tend to have the nails, old horse bridles etc in them. Ruins of old tree houses as well.
Pruning a row of 15 Arizona Cypress CUPRESUSS GLABRA tomorrow to correct years of one sided lopping by Energy Australia (local elec supplier). They stink as well as being sticky.

Eric Frei

Get some before and after pics if you can ... stink? Of what?

Oh, stink of stale beer.

Job done, forgot to take the camera. Not a pretty sight anyway, the trees are overmature and should be replaced.
I find the sap stinks on these, although this lot weren't as bad as some we've done.

Eric Frei

Stinks of stale beer or something else?

I might stink of stale beer sometimes, but the trees stink of something else!

treeseer

Mario you are right about planting associate understory plants for the root relations/symbiosis.

Trev you are right about no one knowing reduction; proper use of pole tools would go a long way on this (as well as climbing skill)

TrevMcRev

Hers a pic of a reserve local to me where they have had all the low stuff removed.



There are continued problems with failures here and several have already been removed. A couple were turned into the most pathetic chainsaw sculptures youve ever seen. The hippy in his combi van nearly got paid as much as the crew that TD'd about 10 big trees!
