Why Species First™ Exists

Species First exists to improve how animal welfare is understood and applied in captivity.

Despite good intentions, many animals experience poor welfare - often not through neglect, but a lack of clear, species-specific guidance.

This platform was created to help close that gap.

With over two decades of experience in conservation genetics, wildlife trade policy and exotic animal welfare - including roles at the Zoological Society of London (ZSL), RSPCA Science Group and contributions to DEFRA Animal Welfare Act working groups - I have worked across the interface of science, policy and practice.

Across these settings, one issue consistently emerged: the gap between intention and outcome.

The Spark: A Lifetime of Fascination

I have always been fascinated by animals. From a childhood menagerie of pets to quiet hours watching birds in my grandmother’s garden; that curiosity for animal behaviour led me to study zoology. Over time, that fascination developed into a growing concern - not only for the impact of trade on the survival of animals in the wild, but for the welfare of those kept in captivity.

The Catalyst: Seeing the Reality

The true catalyst came during a gap year travelling from Morocco to Kenya. The journey became an education in the realities of wildlife exploitation: tortoise shells and gorilla hands sold as souvenirs, monkeys destined for the bushmeat trade and young wild chimpanzees rescued from the pet trade. These encounters were a call to action.

We all carry memories that ignite a fire within us, setting us on a path that shapes our lives. In the Ituri Forest in Zaire (now the Democratic Republic of the Congo) I experienced a quiet but profound interaction with a wild monkey that would shape the course of my life.

I had pitched my tent beside the Epulu River and rested beneath a tree; leaning back to read. I drifted off, then woke to the soft rustling of leaves above me. Looking up, I saw a small, curious face watching me. I froze and waited. After what felt like an eternity, the monkey slid down the trunk and approached; its tiny brown eyes fixed on mine.

Then the unexpected happened.

The juvenile black crested mangabey monkey walked towards my crossed legs, climbed onto my lap, pulled my plait a few times, then curled between my knees and fell asleep.

I sat motionless, legs numb, focused on the tiny black hand resting in my own palm.

          “In that moment, I felt a profound sense of connection and responsibility.”

This young animal brought into focus something fundamental: animals place trust in us; whether in the wild or in our care. That trust carries responsibility.

The Mission: From Conservation Genetics to Animal Welfare

That sense of responsibility shaped my professional life. Back in the UK, I persuaded Professor Sam Berry at University College London (UCL) to support my research into the genetic and welfare implications of captive breeding. I later joined the conservation genetics group at the Zoological Society of London (ZSL), working alongside an international team dedicated to conserving endangered species.

A decade later, I moved to the RSPCA, becoming a Senior Scientific Officer focused on the welfare of exotic animals kept in captivity and the complexities of wildlife trade. This work brought science into direct application - informing policy, improving standards and addressing real-world welfare challenges.

The Challenge: Bridging the Gap Between Intent and Outcome

Through this work, one pattern became clear: Many people who keep animals genuinely want to provide good care. Yet poor welfare outcomes are still common.

This is not always the result of neglect; it frequently begins with:

  • limited or inconsistent guidance

  • outdated assumptions

  • a lack of species-specific understanding.

Animals adapted to complex environments are often described as “easy to keep”, while their biological and behavioural needs remain insufficiently understood or applied. The result is a persistent gap between what people intend and what animals experience.

Why Species First?

Addressing this gap requires collaboration.

Throughout my career, I have worked with keepers, veterinarians, breeders, rescue organisations, policymakers and regulators. These discussions - across disciplines and perspectives - consistently led to the same conclusion:

Clear, evidence-based, species-specific guidance is essential to improving welfare. This is why Species First was created.

What Species First Does

Species First is a platform dedicated to clear, evidence-based, species-specific guidance. It aims to:

  • ensure decisions about animal care are guided by the biological and behavioural needs of each species

  • highlight key welfare considerations in captivity

  • promote practical, evidence-based care approaches

  • support both novice and experienced keepers in making informed decisions

  • share knowledge of species’ lives in the wild to better inform their care

A Collaborative Approach

This is not about criticism - it is about improvement.

Better welfare outcomes depend on working together across sectors, combining expertise, experience and evidence.

Whether you are a keeper, veterinarian, researcher, policymaker or part of a rescue organisation, this platform is designed to support a more informed and constructive approach.

Looking Ahead

This principle is simple:

Put the needs of the species first.

By improving how those needs are understood and applied, we can create more consistent, evidence-based approaches to animal care - benefiting both animals and the people responsible for them.

Join the Conversation

If you are working to improve the lives of animals in captivity - or want to better understand how to meet their needs - this platform is for you.

Join us in building a more informed, collaborative approach to animal welfare.

Welfare outcomes are shaped by environment, husbandry and species-specific needs.
