where are they from, what is their origin?

Critically endangered species - why this category? The article is about the genus, not about the species, and only some species of the genus are endangered (even critically), so this category belongs to the species. For example silver birch (Betula pendula) is very common in the whole Europe and large part of Russia. 62.209.237.4 21:22, 27 February 2006 (UTC) reply

Sorry, this was caused by the {{StatusCritical}} template next to one of the species in the list. It was removed. SCHZMO 12:00, 18 April 2006 (UTC) reply

Infobox

Whilst extracting some info from the Bioata infobox, for a major international broadcaster, I find that this page and some others (Begonia Crassula Ficus Epilobium Birch Oak Willow) contain a link in the infobox, under the genus name, to an individual. Would it be possible to place that elsewhere? At the moment, info-agents reading the page (and less-educated humans such as myself) might think the "L" was the name of the Genus, and follow the hyperlink to the individual whilst expecting a link to the genus page. If the 'birch' page is the page for a genus, this is even stranger...

Just a thought. —Preceding unsigned comment added by 132.185.144.120 ( talk) 14:20, 16 April 2009 (UTC) reply

Pioneer confusion

So are birches pioneer species or not? The current page bluntly claims both, making it unclear. - 68.148.30.86 ( talk) 03:26, 25 May 2009 (UTC) reply

I added the 'contradicts' template to the ecology section. Maybe it acts as a pioneer someplaces but not others?-- 99.237.58.118 ( talk) 20:33, 11 August 2009 (UTC) reply

I do not see the contradiction mentioned. Please explain how you feel the description of birch ecology is contradictory. The page states that birch are capable of rapid colonization in both primary and secondary successions. - Mork the delayer ( talk) 17:21, 15 March 2010 (UTC) reply

why mention Sami people group?

This is a fine article on many aspects of the Birch species. But why mention it is a preferred wood of the Sami people? It is prized by Tlinkit and Haida Native Alaskan people groups also, and I'm sure many, many others as well. Why start a list of all indiginous people groups who prefer to use birchwood over other woods? —Preceding unsigned comment added by 99.185.10.74 ( talk) 01:01, 9 July 2009 (UTC) reply

I removed the passage, this is just a randomly chosen, unsupported mention. This article could use some more wp:reliable sources, and has been tagged for that some time ago. Rror ( talk) 08:23, 9 July 2009 (UTC) reply

sauna switches

to my knowldge they are only made of birch trees - maybe that should be mentioned here. there are various medicinal aspects claimd why young birch sprigs are used. it seems slappers reduce mosquito bite swellings and may be antiseptic. i want proper sources before adding those details, but for sure the birch is the tree for sauna vasta! —Preceding unsigned comment added by 80.186.98.160 ( talk) 17:37, 26 June 2010 (UTC) reply

two photos

I added the two photos of birch wood, one plain and the other finished (with varnish). In real life they look a lot different but they don't look very different in the photos, so I think that maybe only one is needed in the article. Does anyone have a preference as to which one to keep? Bubba73 You talkin' to me? 16:44, 26 July 2012 (UTC) reply

the brich trees have sap — Preceding unsigned comment added by 90.191.204.116 ( talk) 14:10, 30 May 2013 (UTC) The birch has paper like bark — Preceding unsigned comment added by 184.64.152.228 ( talk) 20:24, 27 September 2014 (UTC) reply

Range map is incomplete

On the Betula genus map the genus is missing from Iceland even though both Betula pubescens and Betula nana, along with its hybrids, are native to Iceland [1] [2].

There maybe be other errors in the range map.

No discussion on merge

There is a proposed merge template (with Birch bark) on this article, but no discussion. For the record, I oppose the merge. Birch bark & its uses are distinct enough from the tree in general. Newystats ( talk) 01:26, 26 April 2021 (UTC) reply

Oppose. Birch-bark is a material of extraordinary cultural importance in Scotland, Scandinavia, Russia and subarctic North America. Deserves its own article (which can be substantially expanded). Creuzbourg ( talk) 21:11, 30 April 2021 (UTC) reply
