Abstract

Pojam mangrove odnosi se na biljne zajednice koju nalazimo u slanim močvarnim područjima. Porijeklo naziva mangrove potječe iz zapadne Afrike (Senegal, Gambija i Gruzija) od riječi mangue. Nastale su prije oko 114 milijuna godina. Prilagodbe na ekstremne uvjete obuhvaćaju viviparno razmnožavanje, specijalno prilagođen korijenski sustav i mogućnost tolerancije visokog saliniteta. Mangrove su globalno važne za zaštitu obala od erozije, pružaju zaštitu juvenilnim stadijima riba i morskih beskralješnjaka te su stalna staništa mnogim ugroženim vrstama. Rasprostranjenost mangrova procjenjuje se na oko 181000 km², a najveća površina mangrova nalazi se u južnoj i jugoistočnoj Aziji. Njihova rasprostranjenost uvjetovana je razinom mora i njenim fluktuacijama, salinitetom, temperaturom zraka, nagibom terena, olujama, oceanskim strujama i sastavom tla. Zajednice mangrova obuhvaćaju 54 prave vrste mangrova, iz 20 rodova koje pripadaju u 16 porodica, te 60 pridruženih vrsta iz 46 rodova. Najzastupljenije porodice su Avicenniaceae i Rhizophoraceae. U posljednjih 50 godina nestalo je oko polovice površine mangrova. Najviše ih ugrožavaju urbanizacija, turizam, agrikultura i akvakultura. Očuvanje mangrova obuhvaća suradnju na internacionalnoj, nacionalnoj i lokalnoj razini, obrazovanje i provođenje zakona.

Abstract (english)

The term mangrove referes to the whole floral community that can be found in the saline wetlands. The word mangrove originally came from the West African word mangue. They appeared about 114 milion years ago. Adaptations on the extreme conditions they live in include viviparic reproduction, special root adaptaions and salt tolerance. The global importance of mangroves includes protection of the coastal zone from erozion, protection of the juvenil species of fish and invertebrates and as habitat for indengered species. Distribution takes over a surface of 181000 km², the biggest area of distribution is found in South and Southeast Asia. Their distribution is conditioned with sea level and its fluctuations, salinity, air temperature, ocean currents, shore slope, storms and soil substrate. Mangrove community includes 54 real mangrove floral species, arranged in 20 generas and 16 families, as well as 60 associated species in 46 generas. The most common species belong to families Avicenniaceae and Rhizophoraceae. In the last 50 years half of the mangrove community has evanished. Urbanization, tourism, agriculture and aquaculture represent the biggest threats for the mangrove communities. Mangrove conservation include cooperation on the international, national and local community level, as well as education and enviromental law.
