Respecting and valuing animals and the natural world
Our belief is that a diverse and healthy natural world is valuable in its own right and is essential for ensuring secure and healthy lives for people. This motivates ZSL’s vision and mission, and our other core values follow from this.
Inspiring conservation action
We seek to motivate others to take conservation action in their daily lives.
Achieving excellence in our field
Building on our heritage, Royal Patronage since 1831 and reputation as a learned society, we aim to be an authoritative source of information and good practice for the scientific study, conservation and husbandry of animals.
We aim also to make efficient and effective use of available resources to achieve the highest possible standards in everything we do, in the operation of a successful and innovative conservation organisation.
Acting ethically, responsibly and sustainably
We aim to operate in fair and justifiable ways that do not conflict with our mission or objectives, and which respect the environment.
Valuing everyone we work with
We support and value teamwork and collaboration, strive for fair and equitable treatment of everyone with whom we work and come into contact with, and aim to act with respect and courtesy in all our dealings.
Working for ZSL
The Zoological Society of London (ZSL) is a charity devoted to conservation and education, the worldwide conservation of animals and their habitats being the key role of the organisation.
Our scientists in the laboratory and field, animal management teams at both zoos and our veterinarians contribute wide-ranging skills and experience to both practical conservation and the scientific research that underpins this work.
We are committed to the principle of equal opportunities in employment. We apply policies that are determined solely by job criteria and personal ability.
