Background information - Mangrove forests
Background information - Mangrove forests
Mangrove ecosystems exist exclusively in intertidal zones. The soil is rich alluvial mud washed down from fresh water streams or rivers. The nutrient levels in the mud are high due to prolific amounts of organic matter from mangrove trees dropping leaves. Salt water inundates the forest twice a day due to tidal movement. Mangrove trees are able to exclude or excrete the salt enabling their survival in the salty environment. Some species obtain oxygen in the waterlogged soil through pneumatophores, or breathing roots, which sit above the water. Crabs feed on detritus washed in on the tides and dropped by mangrove trees. They dig burrows to shelter in during high tide and graze on the mud flats at low tide.

The SEED GIS website
The SEED GIS website
SEED stands for Sharing and Enabling Environmental Data. The SEED website is managed by the NSW Government. It is a powerful GIS system that currently collates 5419 sets of environmental data from a range of contributing organisations in NSW onto a single platform.
Explore the SEED database to find ecological information about the fieldwork site including vegetation communities, historical fire data, water catchment health, Aboriginal sites and much more. determine what the vegetation communities are at the fieldwork site.
