The major threat is loss of essential marine habitats across its range. Habitats that are known to be important such as soft corals, sponges and seagrass have all been shown to decline in various locations throughout NSW and QLD. Within Sydney Harbour, it has been shown that this species is very susceptible to councils cleaning the nets as removal of epibiota caused a decrease in numbers.

Threats

Hippocampus whitei is a small (maximum total length approximately 16cm), longsnouted seahorse. It is known to occur in estuaries from St Georges Basin, NSW to Hervey Bay, QLD .

Quollity Conservation Hub's Vulnerability Score:

22

To help compare the relative vulnerability of different species, we have developed a scoring system based on biological and ecological characteristics that influence a species' ability to survive and recover from environmental change and natural disasters.

​

The framework is adapted from assessment methods used by conservation experts following the Black Summer bushfires to help identify species most in need of conservation action, research, and recovery funding.

​

Each species is assessed using a range of factors, including its conservation status, lifespan, reproductive rate, habitat and dietary requirements, ability to disperse or recover after fire, and the number and severity of threats it faces.

In general, the higher a species' score, the greater its overall vulnerability and risk of decline or extinction.

​

Like all conservation assessments, this scoring system is limited by the information currently available. Many threatened species remain poorly studied and receive limited research funding, meaning some assessments rely on the best available scientific knowledge or information from closely related species. As new research becomes available, scores may be updated to reflect our improved understanding.
