Geographical location and size of Lake Eyre (North)
Lake Eyre (North) is situated in the northeastern part of South Australia, near the border with Queensland. It is located in the Lake Eyre National Park, which covers an area of approximately 13,000 square kilometers. The lake itself is about 144 kilometers long and 77 kilometers wide, with a total surface area of around 9,500 square kilometers.
The significance of Lake Eyre (North) to the local ecosystem
Lake Eyre (North) plays a crucial role in the local ecosystem. It is a terminal lake, meaning that it has no outlet and water only leaves through evaporation. During periods of heavy rainfall, water from surrounding rivers flows into the lake, creating a temporary oasis in an otherwise arid landscape. This influx of water provides a vital habitat for a wide range of plant and animal species.
The lake also acts as an important breeding ground for many bird species. When the lake fills with water, it attracts thousands of waterbirds, including pelicans, ducks, and wading birds. These birds come to Lake Eyre (North) to breed and feed on the abundant food sources found in and around the lake. The presence of these birds also attracts other predators such as eagles and hawks.
The unique flora and fauna of Lake Eyre (North)
Lake Eyre (North) is home to a variety of unique plant and animal species that have adapted to the harsh desert environment. The lake itself is surrounded by salt flats and mudflats, which are home to salt-tolerant plants such as samphire and saltbush. These plants are able to survive in the saline conditions and provide food and shelter for a range of animals.
The lake is also home to a number of fish species, including the Lake Eyre hardyhead and the Lake Eyre golden perch. These fish have evolved to survive in the extreme conditions of the lake, including high salinity and low oxygen levels. They are able to tolerate these conditions by reducing their metabolic rate and using specialized adaptations.
The history of Lake Eyre (North) and its traditional owners
Lake Eyre (North) has a rich history that dates back thousands of years. It has been an important site for the local indigenous communities, who have lived in the area for generations. The lake holds great cultural significance for these communities, who consider it a sacred place.

The geological formation of Lake Eyre (North)
Lake Eyre (North) was formed millions of years ago through a combination of geological processes. The lake is located in a depression known as the Lake Eyre Basin, which is one of the largest internally draining basins in the world. The basin was formed by tectonic activity and erosion over millions of years.
The lake itself is a playa, which is a flat, dry lakebed that fills with water during periods of heavy rainfall. The surrounding landscape is characterized by salt flats, mudflats, and sand dunes. These features were formed through a combination of wind and water erosion, as well as the deposition of sediment over time.
The impact of climate change on Lake Eyre (North)
Climate change is having a significant impact on Lake Eyre (North) and its surrounding areas. The region is already prone to extreme weather events, including droughts and floods, but climate change is exacerbating these conditions. Rising temperatures and changing rainfall patterns are leading to increased evaporation rates and reduced water inflows into the lake.
These changes are having a profound effect on the local ecosystem. The reduced water levels in the lake are impacting the breeding and feeding patterns of bird species, as well as the survival of fish species. The loss of habitat and food sources is also affecting other animals that rely on the lake for their survival.
