[edit] Tree facts

There's a lot of good information on the usefulness of trees at the ISA web site. Should this information be included on this page, or as a new page, or just as an External Link? Jonathan Kovaciny 16:20, 1 September 2005 (UTC)

[edit] Bamboo

Should we put bamboo here? It is a kind of grass, and I have seen it called a tree and not called a tree.

Bamboo is a grass, in the Order Poaceae, so I think it should stay well out of trees. Just my thoughts though :-) HelloMojo 04:58, 25 March 2007 (UTC)

[edit] Twigs

There are important distinctions between branches and twigs. Branches are heavy structural elements, representing fairly mature tissue, that support twigs. Twigs, on the other hand, specifically bear leaves, flowers, fruit, and buds, and usually have a markedly different bark and appearance from branches. Twigs are critically important in species identification. I'll edit the separate branch and twig articles later to make sure this is reflected. --user:jaknouse

[edit] Groups of trees

A small group of trees growing together is called a grove? or copse,

My understanding is that a copse refers to a group of trees that is managed by coppicing rather than simply a 'small group of trees'? quercus robur 15:50, 21 Jan 2004 (UTC)

No, I've seen copse used frequently to describe a small stand of trees that have grown completely naturally. One could look it up to be sure though. -lommer 06:10, 12 May 2004 (UTC)

[edit] champion trees

Should champion trees really be included on this page? I think maybe it should have its own page linked from this one. I'm a huge fan of champion trees, but while this page doesn't even really mention trees use as an agricultural product (good or bad, it's pretty relevant)- it does have a whole section on champion trees, something I think should be distinct.

Or how about instead of "champion trees" this section is renamed something like "tree maximums" or the like. The term "champion" usually refers to programs and lists such as American Forests National Register, state champion lists, the UK Tree Register, etc., which are somewhat competitions, hence the concept of a "champion". This segment is more related to the potential maxima of species or trees in general than any lists. Though links or reference to some of those lists are useful.Mar. 2006

I agree that the term "Champion tree" is misleading, and perhaps a seperate article would be more appropriate, possibly summarized in here. 84.238.23.78 13:17, 15 March 2007 (UTC)

[edit] Cacao

Since when is cacao moved from Sterculiaceae to Malvaceae? Can you provide a source for that? Guettarda 23:40, 12 Apr 2005 (UTC)

[edit] Soil Use Misconception

I added this paragraph earlier today, but an annonymous user took it out:

Contrary to popular misconception, trees do not take soil from their roots in order to grow. Like all plants, they instead use the enegy from sunlight to convert gases in air into simple sugars, a process known are photosynthesis. These sugars are then used by the tree as building-blocks to make branches, roots and leaves.

I'd rather not start an edit war over it, but think the information ought be in the article somewhere. Thoughts? Jwanders 23:15, 30 October 2005 (UTC)

Fixed a typo in your passage. While photosynthesis is the main way trees grow (e.g. they use the carbon from carbon dioxide), trees do get nutrients and water from the soil, so this passage could use some work. I'd want an expert to fix it.

The nutrients that trees extract from soil is via osmosis and the nutrients are converted into a salt state by water.. Trees do not remove mineral soils from the ground. HelloMojo 04:58, 25 March 2007 (UTC)

[edit] I.D. this Tree

Does anyone know what kind of tree this is? 71.98.19.72 03:30, 16 April 2006 (UTC)

Maybe a Loblolly Pine? Do they grow in Wisconsin? You might ask for an I.D. at Talk:Pine. --Allen 05:47, 16 April 2006 (UTC)

Probably a red pine, Pinus resinosa.--68.238.127.14 14:51, 16 April 2006 (UTC)

Try the tree identification program on the web.

[edit] oldest trees

see Talk:Lagarostrobos_franklinii --Espoo 09:47, 4 May 2006 (UTC)

The one on this page is a 2500 year old individual specimen, different from the 10500 year old stand you were talking about. SCHZMO ✍ 19:42, 30 May 2006 (UTC)

[edit] Tree Growth - coverage in Wikipedia

Where in Wikipedia would one go to look for an encyclopedic description of tree tip (leader? or top leader?) growth in single-trunk trees like many pines and spruces? I have spent some amount of time poking around Wikipedia in the Tree, Pine, Pinophyta, Spruce, and Evergreen articles, plus many other articles they refer to, and have not been able to find a description of the phenomena. I recall reading about how the tree top-shoots (new growth cells) know to grow taller/straighter than their neighbors many years ago in a book, but do not recall much else. As you can see, I am not a biologist or botanist.

So I don't know if I am just searching in the wrong way within Wikipedia, or if it is merely something that has not yet been stubbed out in Wikepedia. Thanks. N2e 18:55, 13 May 2006 (UTC)

Have a look at the article Apical dominance--Melburnian 03:42, 22 May 2006 (UTC)

Good point! - I've linked apical dominance now - MPF 00:03, 24 May 2006 (UTC)

Thanks Melburnian and MPF! N2e 00:31, 23 June 2006 (UTC)

[edit] That's not a pic of a tree!

Uhh...is it me or is the picture that comes up at the front page a "penis"?? That's not a tree. I'm removing it. —The preceding unsigned comment was added by Housefan (talk • contribs) .

Vandalism from User:Ronnyweasle. He replaced pictures on several other pages. SCHZMO ✍ 19:33, 30 May 2006 (UTC)

[edit] Anyone know this ability of trees?

I don't know what this property of trees is called and I'm hoping someone out there does. If a sign is nailed to a tree, over time the tree will slowly engulf the sign until it is part of the tree and can not be removed without damaging the tree. An example of it can be found here.

Does anyone know what this behavior or property is called?
Who8myrice 04:17, 7 July 2006 (UTC)

As the tree grows into the foreign object, its cambial layer is "wounded" (disturbed) and callus tissue grows around the object to isolate it physiologically from the object. The callus growth can be seen directly to the right of the sign in the externally linked photos. This allows the tree to continue growing and eventually "envelop" the foreign object. The photo on the right shows another example. I'm not aware of a word or short phrase that describes the process, it would be handy if there was one then we could write an article on it :)--Melburnian 07:31, 7 July 2006 (UTC)

On the topic of the ability of trees, is it myth or true that the bulges of unusual form are cancerous, and it is the tree that is pushing them out? I heard that this part of a tree produces very cool designs for woodwork sculpturing, due to the ring patterns. Woody

Have a look at burl Melburnian 12:18, 19 September 2006 (UTC)

ya my grandfather has placed a number of objects in to trees, a crowbar, paddle, chains, ect. don't think I have any photos but I'll see if I could get any of my cousins to take photos Jedi canuck 17:21, 28 February 2007 (UTC)

[edit] Trees in popular culture section?

I have been thinking. Well, trees are a huge inspiration for many of the arts, (especially photography and music), and I was wondering whether it would be worthwhile to create a "Trees in Popular Culture" section to expand the article a bit. If something like this already exists, please post a link, I have a lot of contributions to make. Cheers, woody.

[edit] Non-trees and contenders

Shouldn't there be a mention of border-line cases like palms and banana plants that are sometimes called trees, and whether and why they don't qualify as trees? mglg_(talk) 20:43, 30 August 2006 (UTC)

Indeed

[edit] Apical dominance, again

The first part, defining just what constitutes a tree, now says :having secondary branches supported on a single main stem or trunk with clear apical dominance . Which is not exactly true. Many decurrent trees do not strongly exert apical dominance, hence their form. Individual limbs or leaders on these trees do, but overall, saying single main stem with apical dominance is a defining feature of anything classified as a tree is incorrect. But I'm not changing anything until I hear more opinions. --Trees4est 18:06, 25 November 2006 (UTC)

I agree. Many species of salix, for example, show little or no apical dominance.The Boy that time forgot 16:09, 24 December 2006 (UTC)

[edit] Major tree genera

This list takes up a huge portion of the article's vertical size. It should probably be moved to the end of the encyclopedic content and split into two columns if workable. It might even be better simply to link to such a list, though I can't find any existing 'List of trees' type article that is this extensive. Perhaps the list here should be placed somewhere like List of major tree genera? Richard001 04:52, 19 December 2006 (UTC)

[edit] Life Stages

I removed the statement referring to 30cm being the minimum diameter for sawlogs. Not true across the globe, i.e, minimum top diameter for softwood sawlogs in Britain is 16cm (under bark).The Boy that time forgot 21:31, 23 December 2006 (UTC)

Reference for above,- Anon. (1990). Classification and Presentation of Softwood Sawlogs. Forestry Commission Field Book 9. HMSO. London. ISBN 0-11-710280-6

[edit] Champion Trees

The section on champion trees lists the Australian Mountain-ash as third tallest at 97m. If you follow the link to the Wikipedia page on Mountain-ash it refers to a 114.3m specimen, measured by theodolite and tape measure after it was felled. Should we update this page to be consistant with the one on Mountain-ash ? Thoughts ? Robprain 03:25, 24 January 2007 (UTC)

Is this a list of the tallest trees ever or a list of the ones still alive? Think outside the box 12:45, 13 February 2007 (UTC)

[edit]

Can I just get a count of roughly how many tree types there are ? --terlmann

[edit] Semi-protect?

With the nearly daily vandalism, does anyone think it may be a good idea to semiprotect the page, at least for a little while?--Trees4est 11:34, 27 February 2007 (UTC)

Agreed. The Boy that time forgot 20:48, 28 February 2007 (UTC)

Request for semi-protection was rejected, Wikipedia:Requests for protection, the admin felt that there had not been enough activity. The Boy that time forgot 22:16, 28 February 2007 (UTC)

[edit] Really needs work

The last edit that isn't totally screwed (as of right now, as far as I can tell) is 14:36 on March 2. The next addition has stayed on for some reason, poorly written and superfluous, though the environmental implications of trees should be more thoroughly explained. There have been numerous subsequent edits, mostly vandalism and reverts, but some other gobbeldygook (almost literally) has stayed around and the few good additions need to be kept, including the tags; this page needs help. I don't have the time now, does anyone else?--Trees4est 02:08, 8 March 2007 (UTC)
