Talk:Tropical rainforest

I think the admin should give this page a semi-lock. It will prevent IP users from attacking this page on a regular basis. This has happened so much that it discourages productive contributors from improving the article. I don't know how to request a semi lock. Z22 (talk) 22:56, 12 March 2013 (UTC)Reply

I have suggested that this page has high importance from an ecological point of view as well (hope you all agree!). It follows that we ought to try to improve quality and it seems to me that:

• There is often confusion between true rainforests and other tropical forests (TF: a forwarded page about a collective term); I have moved the information about the ITCZ and Indian monsoons to seasonal tropical forest.
• There is unnecessary repetition here about the different types of TF described fully in its page at Tropical and subtropical moist broadleaf forests.
• At least some of the web-linked references don't work any more.

I would like to read comments on this before proceeding much further Roy Bateman (talk) 03:47, 21 March 2017 (UTC)Reply

Following considerable debate at: Wikipedia:Articles_for_deletion/Tropical_forest, preceded by Talk:Tropical_and_subtropical_moist_broadleaf_forests, the 'generic' page tropical forest was created, with a recommendation that we "move some material from Tropical rainforest into it". Roy Bateman (talk) 13:26, 8 August 2017 (UTC)Reply

the thing rainforests can posses a level of seasonality as regions which are traditionally accepted to posses rainforests such as the Indian subcontinent and Indochina have regions with a prevalent dry season, for example the rainforests of the western Ghats have a dry season of up to 6 months in it's northern half but that dry season is balanced off by the abundant precipitation during the monsoon, same thing occurs in Indochina. the thing is no matter how hard we try to classify and simplify ecosystems and put them into boxes the nuances between each individual case make it nigh impossible to reach at a proper consensus.

Some of the links referenced for these articles are less than confidence inspiring. The language used, calculations made, theme/purpose of such sites and lack of references make these very questionable references. References 5 and 8 a two examples. Reference 5 calculates by multiplying (though the page uses the term 'times it by') golden ratio and fibonatti sequence numbers by figures that come from no where referenced, purportedly because fibonatti sequence numbers and golden ratio show up in nature. Reference 8 is a site about cute animals, once again without references for claims made relating to the information referenced.

I haven't gone through the remaining references, but will attempt to soon. What should be done? Should the references be removed? What about the information claimed based on those references in this article? BGriffin (talk) 18:27, 20 December 2017 (UTC)BGriffinReply

Please correct those atrocious "Pliestocene"(sic) misspellings. — Preceding unsigned comment added by 5.171.72.53 (talk) 02:26, 11 July 2020 (UTC)Reply

The claim that "The forest floor, the bottom-most layer, receives only 2% of the sunlight" needs a citation. I see this exact figure quoted all over the internet on pretty dubious websites, but where is it actually from? Likewise, the claim that 5% makes it through the canopy to the understory. Peer reviewed science, please!

Also, the claim that the Daintree Rainforest is not a rainforest needs a citation.

Also, in the opening: "True rainforests are typically found between 10 degrees north and south of the equator (see map)". Surely that means true tropical rainforests unless, with that one sentence, we are negating the existence of subtropical and temperate rainforests. Surely, a true tropical rainforest is any rainforest within the tropics. I saw another definition that means a forest with more than 2m of rain a year and an average temperature of over 24 degrees. In any case, the map shows some places that do not satisfy any of those conditions. 120.22.182.80 (talk) 05:59, 29 August 2022 (UTC)Reply

I do feel your angst in your post. Much of what is "known" in botanical terms is just subjective proposals and ideas, where there are many divergent thoughts about a particular concept. I'm not sure if there is an official, universally-accepted definition for "rainforest" (it seems not). So re the Daintree, which IMHO is undoubtedly a rainforest, there are those who believe that is not because it doesn't have uniform rainfall throughout the year. The definition of rainforest, as I believe it, is a layered closed forest. Simple as that - rainfall patterns don't enter into it, latitude doesn't enter into it.  Junglenut | Talk 09:15, 29 August 2022 (UTC)Reply

Should have said "layered closed forest with high rainfall"  Junglenut | Talk 09:18, 29 August 2022 (UTC)Reply

Interesting new article on logging in Sabah, Malaysia, on the island of Borneo: https://eos.org/articles/selectively-logged-forests-are-not-broken "The results, which were published in December 2022 in the journal Nature, showed that logged forests can be buzzing with life and ecological functions and therefore have an important role to play in conservation." Some stuff that merits addition to the Conservation section of our article.--Pete Tillman (talk) 11:02, 31 January 2023 (UTC)Reply

The intro says there is NO dry season. The article says at several places that there IS a dry season. Probably the meaning is that even the season that is called dry has quite a lot of rainfall. Anyway, I think this needs to be clarified. But I don't know how.--Ettrig (talk) 10:43, 5 April 2023 (UTC)Reply

When they become strongly seasonal (usually in places >10 deg N or S of the equator), they can be called monsoon or seasonal tropical forests; IMHO the term "rainforest" is often carelessly over-used and prefer the more generic tropical forest. Brgds Roy Bateman (talk) 02:18, 31 October 2024 (UTC)Reply

 

I have replaced this with the UN map: partly to help with the point made above, but also because this map is confusing. I find it difficult to distinguish between the shades of green and, if it is supposed to also show temperate rainforests (irrelevant here surely) then it is incomplete: e.g. the European rainforests are missing.

I suggest we should update the definitions for a Tropical Rainforest in the given article to the definition used by Whitmore and the Radford university Whitmore states that a Tropical Rainforest or Tropical Lowland Humid Forest (including semi-evergreen rainforest) occurs in aseasonal, humid climates where water stress is low to absent, with no regular annual dry season (Whitmore 1998). In general, a tropical rainforest climate can be defined as one with monthly mean temperatures of at least 18°C throughout the year, and an annual rainfall of at least 170 cm (and usually above 200 cm) and either no dry season or a short one of fewer than 4 consecutive months with <10 cm rainfall (Richards 1996, Whitmore 1998) or we can use the definition used by Radford which goes as follows Mean monthly temperatures are above 64° F; precipitation is often in excess of 100 inches a year. There is usually a brief season of reduced precipitation. In monsoonal areas, there is a real dry season of less than 6 months with less than 4 inches of rain, but that is more than compensated for with abundant precipitation the rest of the year. these definition also includes a lot of global regions that are considered rainforest such as Southwest India's Southern Western Ghats and large tracts in S.E Asia which are left out with the current definition. these regions are undoubtedly less diverse than the more aseasonal environments mentioned by the current definition but they are still considered rainforests by most authorities.

This edit request has been answered. Set the |answered= or |ans= parameter to no to reactivate your request.

--> My understanding is that the Tropic of Cancer is 23.5 deg N latitude where the Tropic of Capricorn is 23.5 deg S latitude. The first paragraph (as seen below) indicates true rain forests occur between 10 N and 10 S around the equator (no argument to that), but then it goes on to say 'they [true rain forests] are a subset of the tropical forest biome that occurs roughly within the 28-degree latitudes (in the equatorial zone between the Tropic of Cancer and Capricorn)'.

--> I can't parse the area covered by the tropical forest biome mentioned here. 'roughly within the 28-degree latitudes' - what does that mean? Does it mean from 14 N to 14 S around the equator? Does it mean 28 degrees N and S of the equator (which would pass the limits of the Tropics at 23.5 N or S respectively)? Or is there some other way one is expected to read this part?

--> I don't have the answer, but it needs to be clearer as to the latitudes for the tropical forest biome.

below is the text as copied from the article:

True rainforests are typically found between 10 degrees north and south of the equator (see map); they are a subset of the tropical forest biome that occurs roughly within the 28-degree latitudes (in the equatorial zone between the Tropic of Cancer and Tropic of Capricorn). 174.115.207.207 (talk) 08:42, 30 March 2024 (UTC)Reply

it would be great if someone fixed these since I can't yet. one example is "True rainforests usually occur in tropical rainforest climates where there is no dry season – all months have an average precipitation of at least 60 mm." this should not have an en dash. there are other spots where this has happened, too, especially w/ hyphens being used in place of dashes, though that's usually just because keyboards don't have dashes on them and not as a result of a lack of grammar knowledge. thx 😃 Studentcat (talk) 19:01, 12 May 2024 (UTC)Reply

Hi Studentcat. The en dash is correct in this instance. You may like to read what Wikipedia's Manual of Style has to say about using hyphens and dashes on this page: Help:Introduction_to_the_Manual_of_Style/5. Scroll to the section titled "Punctuation". Cheers, Steve  Junglenut |Talk  21:05, 12 May 2024 (UTC)Reply

that's interesting, how would the en dash be correct there? I don't understand Studentcat (talk) 22:03, 12 May 2024 (UTC)Reply

"Use spaces around the en dash only if the connected terms are multi-unit dates: January 1999 – December 2000." the article doesn't use en dashes this way, so I don't see how the manual supports ur argument Studentcat (talk) 23:06, 12 May 2024 (UTC)Reply

"A hyphen is not a dash. Hyphens are used within words or to join words, but not in punctuating the parts of a sentence. Use an en dash (–) with &nbsp; before, and a space after – or use an em dash (—) without spaces".  Junglenut |Talk  23:16, 12 May 2024 (UTC)Reply

yes, but the quote that I gave specifies how the en dash can be used w/ that specific style guide like an em dash, and it says that it's only used that way with multi-unit dates Studentcat (talk) 23:31, 12 May 2024 (UTC)Reply
