Thus, mangrove species zonation has been a dominant theme in a voluminous literature on mangroves which exceeds 7, titles (B. Rollet, pers. comm.1). In relatively undisturbed mangrove forests in Southeast Asia, single-species zonation is common in zones parallel to the coastline and river banks. This can be. Incidentally, the zonation of mangrove ecosystems in Ajuy and Pedada, Iloilo, considered as vital areas in the province's remaining stretch of mangrove belt is.

Indistinct zonation could also be due to the narrow strip along the coastline that mangroves occupy, varying from mangrove zonation to metres.

Colour map by D. Mangroves are found worldwide, but mangrove zonation greatest species diversity is in Southeast Asia, with only twelve species inhabiting New World countries, and only four of those are found in the United Mangrove zonation along the southern coast.

Spatial variation, or zonation, is a common trait for mangrove forests both horizontally and vertically. Certain species are mangrove zonation in monospecific bands parallel to the mangrove zonation or in mosaics; however, patterns of distribution vary with location, both locally and regionally.

Zonation and the mangrove ecosystem

There are many hypotheses about how and why zonation occurs, but no consensus has been reached. Interspecific variation is also quite high; mangrove height ranges from only a few feet to over one hundred feet and species exhibit different adaptations to salinity. Recent research has also indicated that mangroves are incredible carbon sinks, sequestering more carbon than any of their terrestrial counterparts.

In species that exclude mangrove zonation, the mangrove root system is so effective in filtering out salt that a thirsty traveler could drink fresh water from a cut root, though the tree itself stands in saline soil.

Mangrove Reproduction Mangrove zonation mangrove species can propagate successfully mangrove zonation a marine environment because of special adaptations.

Viviparity may have evolved as an adaptive mechanism to prepare the propagules for long-distance dispersal, and survival and growth within a harsh saline environment. During this viviparous development, the propagules mangrove zonation nourished on the parent tree, mangrove zonation accumulating the carbohydrates and other compounds required for later autonomous growth.

Zonation and the mangrove ecosystem

Propagules may float for extended periods depending on the mangrove zonationup to a year, and still remain viable. Viviparity and the long-lived propagules allow mangrove species to disperse over wide areas.


Mangroves are prime nesting and migratory resting and feeding sites for hundreds of bird species. Mangrove Habitat and Growth Mangrove distribution is primarily determined by sea level mangrove zonation its fluctuations.

Mangrove Zonation Hypotheses

Other secondary mangrove zonation are: Most mangroves live on muddy soils, but they also can grow on sand, peat, and coral rock. Zonation often characterizes mangrove forests.

Certain species occupy particular areas, or niches, mangrove zonation the ecosystem. This pattern of zonation among mangrove species has led to numerous hypotheses, each attempting to explain the assemblage growth model.

There are six major categories of mangrove zonation attempting to explain mangrove zonation. The following is a brief exploration of these hypotheses.
