A new debate is emerging over the future of Talamanca Bay, where a planned ecological mooring field is intended to regulate boat anchoring and help protect the bay’s Posidonia oceanica meadows.

The Talamanca Mooring Association, which represents 48 residents of Ibiza, has expressed strong opposition to the current project, arguing that it does not adequately address environmental concerns and could effectively displace local boat owners who have used the area for decades.

90 Ecological Moorings Planned

The project, promoted by Ports de les Illes Balears (Ports IB) after the Ministry for Ecological Transition transferred responsibility for its implementation, proposes 90 ecological mooring points for boats of up to 20 metres.

The planned investment is approximately €1.67 million, with construction expected to be put out to tender in September, subject to the necessary reports and authorisations.

The moorings would be divided according to boat size:

• 16 spaces for boats up to 6 metres
• 26 for boats up to 8 metres
• 34 for boats between 8 and 15 metres
• 14 for boats between 15 and 20 metres

The project covers around 22.47 hectares of maritime-terrestrial public domain. According to Ports IB, the ecological mooring systems are designed to reduce the damage caused by traditional anchors and chains to the seabed and Posidonia meadows.

Residents Question the New Model

The Talamanca Mooring Association says it is not opposed to regulating the bay or protecting Posidonia.

Its concerns focus instead on how the project is being designed and managed, particularly the lack of a specific reservation for local residents.

The association says an earlier project processed by Ibiza Town Hall in 2016 included an ordinary environmental assessment, a boat-based bilge-water collection service and 30 moorings specifically reserved for local residents.

Under the current Ports IB model, however, stays would be limited to three consecutive days between June 1 and September 30, with reservations made online.

Questions Over Environmental Assessment

The association is also questioning the environmental assessment process.

It argues that a separate mooring project involving 25 boats over 1,727 square metres in s’Arenal Petit, Menorca, is undergoing environmental assessment, while the proposed Talamanca installation would cover 90 boats and around 311,400 square metres without what the association says is an equivalent assessment.

These are claims made by the association, rather than findings that the project has been ruled environmentally inadequate.

Ports IB, meanwhile, presents the project as an environmental measure specifically intended to reduce uncontrolled anchoring and protect Posidonia.

Why Posidonia Matters

The issue is particularly significant because Talamanca's underwater meadows have already faced considerable pressure.

Research cited by environmental organisations has found that the Posidonia meadows in Talamanca remain in poor condition, with monitoring showing limited recovery.

The Balearic Government has also carried out enforcement operations in the bay targeting illegal anchoring over Posidonia, highlighting the environmental importance of the area.

Balancing Conservation and Local Use

The planned buoy field reflects a wider challenge for Ibiza: how to protect sensitive marine ecosystems while maintaining access for local residents and traditional users of the coastline.

Ports IB says the new system will provide more controlled and environmentally responsible mooring, while the Talamanca association wants changes to ensure local boat owners are not excluded from the bay.

With the project expected to move towards tender in September, the discussion over how Talamanca Bay should be managed is likely to continue.
