• We worked with the community to assess perceptions of the status of seagrass beds and local threats;

• During a local community meeting, we drew seagrass bed boundaries onto a projected satellite image with the guidance of the participants;

• Along with representatives of local fishers, community/association leaders and village elders who have a good knowledge of the zone, we collected GPS coordinates of seagrass beds (perimeter points aligning with community maps created in the previous step);

• We then projected the collected GPS coordinates onto satellite images for validation by the local community during a second meeting.

Release management techniques, data collection, and the need for intervention are continuously being assessed to facilitate effective adaptive management on a day-to-day basis.

Dissemination of methods and results is an important tool to communicate to donors, attract new funding or stakeholder support, and increase awareness at a national and international level.

Monthly reports to project partners are published online at www.BirdsOnTheEdge.org in a reader-friendly format that engages with the public. As a result, the project has received funding, attracted post-graduate research, helped network with international practitioners and inspired other organizations.

Work is currently underway to analyze existing data, identify data gaps, and carry out research that will aid the development of a long-term management plan.

Durrell recently incorporated the Open Standards for the Practice of Conservation into their strategic planning using Miradi software.

Captive reared birds tend to use the same type of nest in which they were raised. Based on this theory, nest boxes were installed along cliffs and a working quarry adjacent to the release site. Ronez, the quarry owners, paid for a UK expert to visit Jersey to help plan, design, and install the boxes.

The first nests, in 2015, were inside quarry buildings, not the boxes. Boxes began to be used as competition for nest sites increased. When two nests failed due to being built on dangerous machinery, staff installed boxes and successfully encouraged the pairs to nest in them, allowing quarry staff to continue operations.

Nesting activity is closely monitored allowing staff to estimate incubation, hatch, and fledge dates based on pair behavior at the supplemental feed and/or from direct nest observations. Chicks are ringed and DNA sexed in the nest where feasible. Alternatively, fledged chicks that visit the supplemental feed site can be trapped in the aviary when called for food, ringed, and immediately released. This option was used in 2020 and 2021 when COVID-19 prevented access to the quarry.

The recently revised Jersey wildlife law gives full protection to chough nests. Staff are now working to increase public awareness and offer nest boxes as mitigation when choughs nest on private property.

Between 2013 and 2018, captive-bred choughs were soft-released in small cohorts replicating normal family group size.

The plan was to release chicks shortly after fledging although sub-adults (< 4 years old) were used for the first release. Captive breeding at Jersey Zoo was not successful until 2014.

Cohorts acclimatized and socialized in the release aviary for a minimum of 2 weeks and trained to associate a whistle with food, enabling staff to call birds back to the aviary if needing re-capturing. Each cohort was initially given a set amount of time outside then called back in for food and confined until the next release. Duration outside increased day by day until reaching full liberty. Staff followed any bird that failed to return attempting to lure it back if feasible. If it had gone to roost, staff would return at sunrise to retry.

All birds were fitted with leg rings. Tail-mounted VHF transmitters were fitted to all birds released between 2013 and 2016. Initially, they received three supplemental feeds a day, as in captivity, reducing to once a day. This continues to the present day permitting close monitoring.

Jersey Zoo’s Veterinary Department conducted pre-and post-release faecal screening to monitor parasite levels, administer wormer if necessary, and have also treated physical injuries.

Paradise Park loaned two pairs of choughs to Jersey Zoo in 2010 to begin a captive breeding program. To establish a wild population, it was estimated 30 to 50 juveniles needed to be released over a 5 to 7-year period. Any shortfalls in numbers would be supplemented by importing juveniles from Paradise Park.

Jersey Zoo transformed two aviaries into dedicated breeding aviaries and created a display aviary to house the flock over winter mimicking natural behavior. Nest boxes were fitted with cameras for remote monitoring. Nestlings are susceptible to aspergillosis and nematode infections in captivity. Cameras allow staff to monitor for clinical signs and intervene as soon as possible to ensure survival.

Paradise Park, with decades of experience breeding choughs, provided guidance, training, and financial support. Jersey staff spent time behind the scenes at Paradise Park to learn about chough husbandry reciprocating once the release was underway with staff from the UK visiting Jersey.

Despite releases ending in 2018, Jersey Zoo continues to breed chough in captivity providing a backup in case there is a renewed need to release. It also allows a conservation message to be communicated to the public through educational talks at the display aviary. Surplus juveniles are returned to Paradise Park’s breeding program.

Jersey farmland bird transects have been conducted by Durrell staff, partners and volunteers since 2005. This data combined with other datasets highlighted declining population trends leading to the publication of The Conservation Status of Jersey’s Birds.

In 2010, a partnership between Durrell, the National Trust for Jersey, and the Government of Jersey established Birds On The Edge, a conservation initiative to restore depleted coastal farmland bird populations. The reintroduction of chough acting as a driving force to implement change.

Feasibility studies supported the need to reintroduce chough; natural colonization was not a feasible option. They also identified a release site at Le Don Paton on the north coast. The National Trust for Jersey introduced a free-ranging flock of Manx loaghtan sheep to graze the site ensuring the birds had natural foraging habitat once released. The National Trust also purchased adjacent agricultural fields to avoid any land management conflicts and to sow conservation crops (another component of the initiative).

A reintroduction plan was created following IUCN Guidelines for reintroductions and other conservation translocations. This document assisted in securing licensing for the release, initial funding, and provided a way of clearly communicating intentions to stakeholders.

Our proposal to generate a Community Ecopark with walking trails in the sector Olga, mainly seeks to link the community, being these the main protagonists in the development of day-to-day activities of the Ecopark.  as tourist guides, vendors of handicrafts, sellers of agricultural products, patio grown goods and multiple activities more. Thus, generating sustainable development over time, bringing important resources to a community that today lives in poverty and its members do not enjoy state, local or private support.

This project is considered a pilot or seed project whose success will allow multiplying its methodology and actions in other water basins in Colombia and the world where conditions are similar to that of the La Olga sector are visualized. In addition, the success of this project will allow meeting 2 fundamental needs:

a). Improve the quality of life of the community.

b). Increase per capita income of families involved in the project

c). Ensure that sustainable and sustainable activities are carried out in the area that benefits the environment.
