The Journey of Species Survival is Durrell's main tool for planning and tracking how we deliver our mission of saving species from extinction. We monitor each species through 13 management stages and four main phases as our actions drive its population recovery from the brink of extinction back to safer levels.

Phase I: Assessment & Planning

Phase I: Assessment & Planning

The first phase of the survival journey focuses on gathering the information required to plan our approach to effectively manage the recovery of the species.

Rapid assessment

Rapid assessment

2004

A study into the habitat requirements of the orange-tailed skink enables Durrell to estimate its distribution on Flat Island, information which becomes vital when choosing new sites for the emergency translocations. Research also implicates the invasive Indian musk shrew as both a historical and current high impact threat to the skink.

About the Rapid assessment stage
Field missions are used to assess species conservation status, key threats and initial actions needed to kick start the programme.

Rapid response

Rapid response

2008

Durrell, MWF and NPCS conduct an emergency translocation of 82 orange-tailed skinks from Flat Island to a neighbouring offshore island as the risk of invasive predators intensifies when plans are launched to increase tourism to the island.

About the Rapid response stage
If extinction risk is very high, captive breeding programmes or rapid field interventions might be used to avert an immediate risk of extinction.

Stakeholder engagement

Stakeholder engagement

2008

Consultations and permissions are sought from local government and community stakeholders with partners actively involved in the emergency translocation of orange-tailed skinks from Flat Island.

About the Stakeholder engagement stage
Conservation actions are successfully increasing the species’ numbers and the programme structure is now capable of monitoring and adapting to new or re-emerging threats to the species.

Full assessment

Full assessment

2009

Following seven years of intensive monitoring, the first reliable estimate of the orange-tailed skink population on Flat Island is published at over 25,000 individuals. Research into the diet, health and threats facing the skinks is also completed.

About the Full assessment stage
Intensive research into ecological, environmental and socio-ecological factors affecting the species provides a baseline to inform the planning stage.

Planning & partnership

Planning & partnership

2008

With partnerships already well-developed, focussed planning takes place for further translocations to other offshore islands and to set up a captive breeding population at Durrell’s Wildlife Park in Jersey.

About the Planning and partnership stage
Conservation targets and detailed action plans are developed to guide the programme's efforts. Partnerships and governance are also outlined to ensure the programme remains on track.

Phase II: Intensive Care

Phase II: Intensive Care

This phase involves the testing and implementation of intensive management actions to tackle the main threats to a species in order to stabilise its population and promote recovery. It often requires the most resources as it lays the foundation for a species’ long-term recovery.

Trialling actions

Trialling actions

2008

With the translocation methods, including animal capture, transportation and release, already trialled as part of the rapid response, the programme moves quickly to scaling up actions. The aim is to establish further populations of orange-tailed skinks in order to reduce extinction risk.

About the Trialling actions stage
Conservation actions are tested on the ground, results are monitored and techniques are adapted to develop effective management actions.

Scaling up actions

Scaling up actions

2010

Further translocations of skinks from Flat Island to two offshore islands are conducted following the confirmation that shrews have invaded Flat Island. A year later skinks are taken into captivity at Durrell as a safety measure.

About the Scaling up actions stage
Once effective management actions are developed they can be rolled out across the intervention zone.

Intensive management

Intensive management

2014

Regular monitoring shows the two translocated sub-populations of skinks are surviving and one is increasing. These populations are protected by enhanced biosecurity and predator detection efforts. Research into the underlying mechanisms of the shrew impact on skinks on Flat Island is also being conducted as this population is now suspected to be extinct. The captive breeding programme is now fully established.

About the Intensive management stage
After actions have been scaled up they are then intensively implemented to bring primary threats under control, enabling the start of the species' recovery.

Adaptive management

Predicted 2016

About the Adaptive management stage
Conservation actions are successfully increasing the species’ numbers and the programme structure is now capable of monitoring and adapting to new or re-emerging threats to the species.

Phase III: Long-term Management

Phase III: Long-term Management

Once a species reaches this phase the population recovery is well underway but the sustainability and long-term robustness of the programme needs to be ensured.

Minimum management

Predicted 2020/Future Target

About the Minimum management stage
Moving towards sustainability, the intensive actions are scaled back to minimum levels of effort required to meet conservation targets.

Capacity-building

Predicted 2024

About the Capacity-building stage
The capacity building activities within the programme enter the final stage and local partner(s) lead the strategic and operational management of programme.

Final evaluation

Predicted 2030

About the Final evaluation stage
A detailed programme evaluation reviews progress towards conservation targets, final responsibilities are passed onto local partners and a new long-term action plan is agreed.

Phase IV: Watching Brief

Phase IV: Watching Brief

This phase signals the exit point for Durrell as a species reaches the end of its survival journey.

Watching brief

Predicted 2035

About the Watching brief stage
Durrell steps back from the programme and provides technical support to local partners on request.
