The Liben Lark - History • Currently with a population of not more than 200 individuals and a number of threats it is listed as critically endangered.

History • Surveys in 2007 confirmed a number of things. – Its range previously estimated at 750 sq km was only 40 sq km. – Its population previously thought to be about 2000 birds was estimated to between 90-256 individuals.

Threats

Threat 1 - Agriculture

Threats 1- Agriculture

Threats 2- Overgrazing

Bare areas formed by ants

Threats 2 - Overgrazing

Threat 3 - Bush infestation Areas with bush and scrub growth

Overgrazed but still fair habitat for the Liben Lark

Threat 4 – Donkey Carts and Paths Donkey carts are commonly used for transport on the Dida Liben

Continual use creates paths (scars on the plains)

Conservation work Consulting local people during all steps of conservation action insures success

Conservation work Bush infestation decreases grazing areas and habitat for birds

Bush clearing by local people to increase pasture and habitat for birds

Conservation work Section of the plains cleared of bush and scrub – more suitable as a habitat for the Liben Lark

Challenges • Creating rapport with local communities takes lots of time • Finding commitment in people • Too many stakeholders to deal with • Project is always limited in time • Expectation from an NGO is high • Policies are not ive

Future • More time is needed to see change _ Projects are always limited to a few years time. • We must ensure sustainability of the project – Sustainability has different meanings. It can be associated to our lifestyle. Using no more than our fair share of the planet’s resources. It is also associated to balancing our needs to the needs of the environment. It can mean living in harmony with the immediate environment we live in.

Future • One good way of ensuring sustainability is to hand over the project slowly to local people – Establishing a site group. – Establishing a concern group that would stand for the environment. – Coming up with a system where local people generate a livelihood from nature.
