WetlandUpdate April 2021

Aquatic fauna passage (biopassage)

Australian native fish and other water-based fauna need a range of habitats to complete their life cycle and rely on specific seasonal and life stage habitats.

The Aquatic fauna passage (biopassage) pages provide general information about aquatic fauna passage, the types of movement and ways, biopassage structure (fishway) mapping and a user defined template are also provided to faciliate improved aquatic fauna passage.

 

 

Nitrogen processes

The nitrogen processes pages provides synthesize information on nitrogen processing in the landscape. These processes can be complicated, these pages provide an intergrated understanding of chemical processes and discribes the complicated science related to the inputs, processes, stocks, outputs, effects, and management issues associated with Lacustrine, Paulstrine, Mangrove and Rainforest systems. Nitrogen is essential to life on Earth. It is a component of all proteins, and it can be found in all living systems. Nitrogen compounds are present in organic materials, foods, fertilisers, explosives, some wastewaters, and poisons. Nitrogen is crucial to life, but in excess it can also be harmful to the environment.

Hydrology

Hydrology is the study of the properties of the Earth’s water, particularly the distribution and movement of water between the land surface, groundwater and atmosphere. This new section provides information on how the hydrology can be studied at a range of scales (such as catchment, regional or global) and from different perspectives (for example, focusing on a particular wetland, a river catchment or a groundwater aquifer) depending on the questions being asked.

Feral pigs

 

Basic information is provided on Feral pigs. Feral pigs can cause extensive environmental damage and damage to environmental, social, cultural, and economic values. Additionally, predate on native wildlife, destroy habitats, compete for resources against native wildlife, and invasive weeds, disrupting the ecosystem services provided by wetlands and other water systems.
