“…Some other forest types such as tropical mangrove forests had dead tree volumes ranging from 35.1 to 104.2 m 3 ha −1 (Allen et al 2000). Obtained amount of dead tree in Iran is lower than tropical forest.…”

Sefidi K, Etemad V. 2014. The amount and quality of dead trees in a mixed beech forest with different management histories in northern . Dead tree (fallen logs and snags), is regarded as an important ecological component of forests on which many forest dwelling species depend, yet its relation to management history in Caspian forest has gone unreported. The aim of research aim was to compare the amounts of dead tree in the forests with historically different intensities of management, including: forests with the long term implication of management (Patom), the short term implication of management (Namekhaneh) which were compared with semi virgin forest (Gorazbon). The number of 215 individual dead trees were recorded and measured at 79 sampling locations. ANOVA revealed volume of dead tree in the form and decay classes significantly differ within sites and dead volume in the semi virgin forest significantly higher than managed sites. Comparing the amount of dead tree in three sites showed that, dead tree volume related with management history and significantly differ in three study sites. Reaching their highest in virgin site and their lowest in the site with the long term implication of management, it was concluded that forest management cause reduction of the amount of dead tree. Forest management history affect the forest's ability to generate dead tree specially in a large size, thus managing this forest according to ecological sustainable principles require a commitment to maintaining stand structure that allow, continued generation of dead tree in a full range of size.

“…In some countries, mangrove wood historically formed an important commercial fuel for industries like bakeries and clay-firing kilns, although this is less common today because of the ready availability of alternative fuels, like natural gas and electricity, and policies aimed at discouraging mangrove cutting Naylor et al, 2002;Walters, 2003). Nonetheless, remote coastal communities in many parts of the tropics continue to depend heavily on mangrove wood for domestic fuelwood consumption, and commercial markets that sell mangrove charcoal to nearby towns and urban centers are not uncommon (Untawale, 1987;Walters and Burt, 1991;Alvarez-Leon, 1993;Allen et al, 2000;Dahdouh-Guebas et al, 2000b;Glaser, 2003).…”

“…Heavily impacted stands are often characterized by few species of widely dispersed, dwarf-like trees manifesting a distinctly ''bushy'' appearance. Collateral damage from selective wood cutting may result in a net increase of dead wood in the forest (Allen et al, 2000). By contrast, local people in some settings intentionally forage for deadwood (for fuel) and thereby reduce levels of naturallyoccurring deadwood (Walters, 2005a).…”

“…Tropical storms originate east of the islands (Gray, 1968) and first reach the windward, eastern coast, where high winds tend to inflict more damage than on the more protected, leeward western coast (Schneider, 1967). As a result, S. alba trees that are sensitive to high winds tend to occur at higher densities and basal areas in the more protected mangrove forests on the leeward side of the island compared to the windward side (Allen et al, 2000;Kauffman & Cole, 2010).…”

Stand structure influences nekton community composition and provides protection from natural disturbance in Micronesian mangroves

Structurally complex mangrove roots are thought to provide foraging habitat, predation refugia, and typhoon protection for resident fish, shrimp, and crabs. The spatially compact nature of Micronesian mangroves results in model ecosystems to test these ideas. Tidal creek nekton assemblages were compared among mangrove forests impacted by Typhoon Sudal and differing in stand structure. Structurally complex Rhizophora spp. stands were predicted to support higher densities and different communities of nekton and to provide greater protection from typhoons compared to less complex Sonneratia alba/Bruguiera gymnorrhiza stands. Lift net data revealed that structural complexity did not support greater nekton densities, but did support significantly different nekton assemblages. The cardinalfish Apogon ceramensis and goby Oxyurichthys lonchotus had significantly higher densities in S. alba/B. gymnorrhiza mangrove creeks, whereas the silverside Atherinomorus lacunosus and diogenid crabs had significantly higher densities in Rhizophora spp. creeks. Similar nekton densities 17 and 4 months after the typhoon in Rhizophora spp. creeks provided indirect evidence that structural complexity increased protection for resident nekton from disturbances. Findings indicate that studies of structural complexity and nekton densities may be better served when individual species are compared and that diverse mangrove tree assemblages will support diverse nekton assemblages that may be more resilient to disturbance.
