Talk:Mangrove

message: I do not question that mangroves protect against tsunamis, I just don't quite understand.
My imagination can't grasp precisely what happens as a mangrove protects against a tsunami. I just imagine the debris crawling up the road just the way cars and bits of buildings do. Would the additional debris make the wave move slower? I suppose it would absorb some of the energy, and the destruction of those trees would translate into less destruction elsewhere.
Would salt marshes and wetlands do the same kind of thing against tsunamis as mangroves?
Those, at the very least would be lining a bay instead of housing. 
Or, I just thought, would the mangrove help trap the dirt that the tsunami would pull out to sea? I remember a lot of islands were eroded to the point of being more underwater than before on the news. Could mangroves prevent that?
Thanks a bunch
Also, should an explanation for how mangroves protect against tsunamis be put into the article?
:I suppose the most important thing has to do with dissipating the energy of the tsunami.  The trees are well-anchored, and they are somewhat flexible - so they would absorb a lot of energy before they broke.  Stilt-rooted species have the equivalent of a series of guy-wires holding them down, rather than a single trunk - the point at which the fail mechanically is going to be much further along than a normal tree.  By bending and absorbing the energy, they reduce the energy of the wave hitting the land.  Guettarda 19:02, 8 December 2005 (UTC)

message: On the spanish wiki the tree is es:Mangle (interwikilinks was pointing to the laundry machine en:Mangle entry here so I'm fixing that) and the ecosystem formed by many Mangles are called Manglares (and interwiki for es:Manglar was en:Mangrove ). SO I'm confused. I've just traveled to a Manglar past week (took lots of pictures for improving articles) but before I'd like to settle the naming issue to check which one is right. I can confirm that at least in spanish, Mangle is the tree and Manglar the mangle forest. (The entry also mentions the word Mangal for the forest, but that's something I inferred, it's not explicit) --  ( drini's page ☎ ) 07:02, 31 December 2005 (UTC)
replies: text: I think you are correct: mangal is English for the ecosystem (= manglar), while mangle is latin (e.g., Rhizophora mangle, the American or red mangrove tree) for the plant (= mangrove). The confusion being that you have two different languages in your list of terms. In English, the term "mangrove" is used comnmonly for both the tree and the ecosystem (e.g., "mangrove forest") - Marshman 20:14, 2 January 2006 (UTC)

message: Don't say "Mangrove crabs are important animals in the habitat."  Say instead why they are important. Maybe something like "Mangrove crabs improve the nutritional quality of the mangle muds for other bottom feeders by mulching the mangrove leaves." (Skov & Hartnoll 2004).

message: The third paragraph of the 'General description' section states:
:It is often stated that mangroves provide significant value in the coastal zone as a buffer against erosion, storm surge and tsunamis. While there is some attenuation of wave heights and energy as seawater passes through mangrove stands, it must be recognised that these trees typically inhabit areas of coastline where low wave energies are the norm. Therefore their capacity to ameliorate high energy events like storm surge and tsunamis is limited. Their long term impact on rates of erosion is also likely to be limited. Many river channels that wind through mangrove areas are actively eroding stands of mangroves on the outer sides of all the river bends, just as new stands of mangroves are appearing on the inner sides of these same bends where sediment is accreting.
The 'Mangrove ecosystems' subsection states:
:Mangroves are excellent buffers between the violent ocean and the fragile coast, especially during hurricanes, which can bring powerful storm surges onto shores. The massive mangrove root system is quite efficient at dissipating wave energy. This same root system also helps prevent coastal erosion. As tidal water flows through the root system, it is slowed substantially enough so that it deposits its sediment as the tide comes in, and the return flow is kept slow as the tide goes out to prevent resuspension of some of the finer particles. As a result, mangroves can build their own environment. Because of the uniqueness of the mangrove ecosystems, they are frequently the object of conservation programs including national Biodiversity Action Plans.
Neither section cites any sources. So, are mangroves "excellent buffers", or they do they provide only "limited" protection against storms and erosion. As I have time I'll try to research this. However, another alternative is to remove both paragraphs if sources are not found. -- Donald Albury 13:37, 27 May 2007 (UTC)
replies: text: I've requested citations. Actually, there are a number of places in this article that don't cite sources, but I've got enoug to keep track of without plastering this article. If I get a chance I'll search for suitable spurces, but that may be a while. -- Donald Albury 21:03, 27 May 2007 (UTC)
replies: text: I have provided citations.  I was told that there is a good discussion of this in Wolanski, Eric. (2007) "Protective functions of coastal forests and trees against natural hazards" Food and Agricultural Organization (FAO) of the United Nations, Rome, but all I can find is an Abstract.  Also there are studies that show that vegetated river banks erode 2 to 3 times slower than unvegetated ones, I will look for a summary article on that to remove the last citation requested in this section. --Bejnar 16:01, 28 May 2007 (UTC)
replies: text:  Since I re-organized these two sections a little, the contradiction between the paragraphs became more obvious.  I tried to reconcile the information into two coherent paragraphs.

thread_title:  Contradiction between sections 

message: On 27 August 2007, in the "New Guinea and environs" section, an editor inserted "Middle Beach" in the middle of a sentence that was supported by the citation to "Mangrove ecosystems in Australia: structure, function and status".  To the best of my knowledge, that citation does not support the insertion.  Can anyone provide the page number in the 1995 State of the Marine Environment Report for Australia that discusses the Middle Beach mangroves?  Or can someone provide other citation for their existence? I have temporarily deleted Middle Beach from the sentence pending citation. --Bejnar 18:58, 29 August 2007 (UTC)

message: FTA:
: Mangroves are also extremely important to the aboriginal "footprints" that are part of their cultural heritage. The mangroves of North Stradbroke are an excellent example of this phenomena, and this is obvious if you are to visit there. We as humans need the mangroves because, as a race, we depend on the numerous materials found there such as gold and other such lucrative minerals.
If anyone has the faintest idea what this is supposed to mean, please translate it into plain English.  If nobody can shed any light on this paragraph, it should probably be removed. 81.86.133.45 12:45, 8 September 2007 (UTC)

message: An unsourced comment about "mangrove's pungent odor" was removed from the section on Nutrient uptake. I have found ad source on why the soil in mangals is sometimes very pungent (Ecology and Environment of Mangrove Ecosystems, Page 110, from the United Nations University OpenCourseWare Syllabus), but I'm not sure where it would fit in to the article.

message: The lead sentence gives the distribution of mangroves as "mainly between latitudes 25° N and 25° S". However, this is not consistent with the map, from which 30° N and 30° S would be a better fit, with the exception of Aus and NZ, where there is a further southward extension. Unless there is any objection, I propose to make this change. Plantsurfer (talk) 11:07, 19 March 2015 (UTC)
