The Forest's Guardian
Liza Maria Veiga's Race to Save Amazon's Rarest Primates
A tribute to the primatologist who dedicated her life to protecting some of the world's most endangered monkeys
The Primatologist Who Wasn't Supposed to Be
When Liza Maria Veiga died in October 2012 just days before her 48th birthday, the world lost more than a brilliant scientist—it lost a fierce protector of Amazon's most vulnerable primates and a mentor who had forged an unlikely path into the heart of tropical conservation. In a field dominated by career academics, Liza stood apart: a business economics graduate who found her calling not in boardrooms but in the vanishing forests of Brazil, where she would become one of Neotropical primatology's most productive authors and editors 1 .
Her story defies convention—a remarkable journey from business economics to pioneering conservation, from the University of Cardiff to the deepest Amazon rainforests.
In just twelve years of primatology work, she authored 69 book chapters, 12 journal articles, and 33 conference abstracts, all while championing some of the most endangered and forgotten primate species on Earth 1 . This is the story of how an unconventional thinker became the last hope for monkeys teetering on the brink of extinction.
An Unlikely Path to the Canopy
Liza's academic journey began with a degree in business economics from the University of Cardiff in 1984, followed by a master's degree in Environment and International Development from the University of East Anglia in 1995 1 . She initially worked for the Overseas Development Administration, a path that would seemingly lead to a career in policy or international development 1 .
A career change brought a move to France, where she met a Brazilian academic who taught at the Federal University of Pará. Her subsequent move to Brazil brought her into contact with tropical forests and, through another translocated Brit, the primatologist Stephen Ferrari, with the region's primates 1 . Ferrari, then teaching at UFPA's Department of Experimental Psychology, recognized in Liza the qualities of dedication, persistence, insight, and organization that a field primatologist requires 1 .
Accepted into the Ph.D. programme, Liza scaled the twin learning curves of Portuguese and Primatology simultaneously, producing her thesis "Ecologia e comportamento do cuxiú-preto (Chiropotes satanas) na paisagem fragmentada da Amazônia oriental" [Ecology and behaviour of the black bearded saki (Chiropotes satanas) in the fragmented landscape of eastern Amazonia] in 2006 1 . It was, characteristically, right on time—the foundation for what would become an extraordinary, if tragically cut short, career.
Champion of the Forgotten Monkeys
Based at the Museu Goeldi in the northern Brazilian coastal city of Belém, Liza taught in the Post-graduate Programme in Animal Sciences at the Federal University of Pará (UFPA) in the same city, where she also coordinated the behavioral ecology study unit 1 .
Her scientific contributions were both broad and deep:
She co-founded the Pitheciine Action Group, a Primate Specialist Group affiliate dedicated to promoting research and conservation of her beloved bearded sakis and their relatives the uacaris and titis 1 .
She served as a council member of the Brazilian Primatological Society and was an editor for Neotropical Primates 1 .
She became the IUCN point of contact for Neotropical primate conservation and served as coordinator for the Pitheciines (Callicebus, Pithecia, Chiropotes, and Cacajao) for the IUCN Primate Specialist Group 1 .
She made substantial contributions to the IUCN Red Data Book, coordinating the sheets for almost all pitheciine species and detailing their ecology, conservation status, and threats 1 .
Liza's work was characterized by a sense of urgency—she understood that the primates she studied were in a race against time, with habitat destruction and hunting pushing many species perilously close to extinction.
The Ka'apor Capuchin: A Case Study in Conservation Crisis
Perhaps nowhere was Liza's conservation approach better illustrated than in her work with the Critically Endangered Ka'apor capuchin monkey (Cebus kaapori), one of the most threatened primate species in the Brazilian Amazon 3 . This species exemplifies the conservation crisis facing many Amazonian primates—endemic to a region where the intensification of habitat-degrading activities over recent decades has left remnant populations in a completely fragmented landscape 3 .
The Experimental Approach to Saving a Species
Liza's project, "Distribution and Conservation of Remaining Populations of the Critically Endangered Ka'apor Capuchin Monkey," aimed to identify remnant populations, implement an environmental education program, and contribute to "Conservation Action Plans" for this critically endangered primate 3 .
Her methodology combined cutting-edge technology with grassroots engagement:
- Distribution Modeling: Using species distribution modeling software to produce maps of potential occupation areas within the states of Maranhão and Pará 3 .
- Field Verification: Personally visiting locations identified during the modeling process to confirm the species' presence 3 .
- Community Engagement: Producing pamphlets and undertaking workshops at local schools and communities to stimulate interest in the species' plight 3 .
- Capacity Building: Training young Brazilian biologists to undertake conservation research 3 .
- Partnership Development: Building links with private landowners and Amerindians at locations where monkey populations were found to explore protection opportunities 3 .
- Policy Integration: Supporting the development of effective conservation strategies with state and national agencies, contributing to a formal Conservation Action Plan for the species with the Brazilian Ministry for the Environment 3 .
Results That Made a Difference
Liza's multifaceted approach yielded significant conservation outcomes, demonstrating that saving species requires addressing both scientific and human dimensions of conservation.
Her work revealed just how rare and susceptible to hunting the Ka'apor capuchin is, with recent surveys and behavioral studies highlighting its precarious situation 3 . More than just documenting the decline, Liza implemented the urgent studies needed to locate and determine the size of remnant populations while simultaneously working to inform the public of the species' plight through environmental education programs 3 .

The Primatologist's Toolkit: Essentials for Field Conservation
Liza's work exemplified the multidisciplinary approach required for effective conservation in the 21st century. Her "toolkit" bridged traditional field biology with modern technology and community engagement.
Field Technology
Species distribution modeling software, population surveys for identifying remnant populations and priority habitats.
Educational Tools
Workshops, pamphlets, school programs for building local support for conservation initiatives.
Collaborative Networks
Pitheciine Action Group, IUCN networks for coordinating conservation efforts across regions.
Policy Instruments
IUCN Red Data Book, Conservation Action Plans for implementing legal and institutional protections.
Capacity Building
Training programs for young biologists to ensure long-term conservation leadership.
Community Engagement
Building relationships with local communities to foster stewardship of primate habitats.
This diverse toolkit allowed Liza to address conservation challenges from multiple angles simultaneously, recognizing that scientific knowledge alone is insufficient without local buy-in, policy support, and continued monitoring.
A Legacy That Lives On
Liza Maria Veiga's passing was described as "a huge loss not only for academic primatology and for all those who knew her, but also for the primates that she loved so strongly and for whose protection she fought with such passion and dedication" 1 . Colleagues, co-workers, students, and friends felt the loss of her dynamism, enthusiasm, and organizational power 1 .
- The Pitheciine Action Group she co-founded, which continues its work today
- The students she taught at the Federal University of Pará
- The conservation frameworks she helped establish with Brazilian government organizations
- The research methodologies she pioneered for studying and protecting endangered primates
Liza's career stands as a powerful testament to the idea that it's never too late to change paths and make an extraordinary contribution. Her journey from business economics to primatology reminds us that diverse backgrounds and unconventional paths can bring fresh perspectives to entrenched conservation challenges.
More than a decade after her passing, Liza Maria Veiga's work continues to inspire a new generation of primatologists and conservationists—those who understand that saving species requires not just scientific expertise, but passion, dedication, and the ability to bridge worlds from the forest canopy to government offices. In the endangered primates of the Amazon, her fight continues, and her legacy endures in every patch of protected forest and every community that now understands the value of the biological treasures in their midst.
