Global biodiversity is under huge pressure as human activities continue to accelerate species extinction and ecosystem degradation. In a new study published in PsyCh Journal on May 4, researchers from the Xishuangbanna Tropical Botanical Garden (XTBG) of the Chinese Academy of Sciences introduced the first validated scale to measure "naturalist identity," offering new insight into how how this identity can inspire meaningful action to conserve biodiversity.

Although identity is a fundamental concept in social psychology, its application in conservation education has been limited. The researchers define naturalist identity as the extent to which individuals see themselves as being curious about, knowledgeable about, and engaged with the natural world, similar to the identity of an amateur naturalist. Unlike general "environmental identity" which focuses on attitudes and values, naturalist identity encompasses self-recognition and competence. For example, individuals may see themselves as naturalists and feel capable of explaining natural phenomena to others.

Using a mixed-methods approach, including interviews with naturalists, surveys, and statistical modeling, the researchers developed a 10-item Naturalist Identity Scale (NIS). The scale was tested across more than 800 participants, including both self-identified naturalists and university students, and showed strong reliability and validity.

The researchers found that a stronger naturalist identity is associated with more frequent biodiversity conservation actions, such as intervening when wildlife is harmed or sharing nature-related knowledge. Importantly, this relationship is partially explained by a sense of moral obligation: people who strongly identify as naturalists are more likely to feel personally responsible for protecting biodiversity, which in turn motivates them to take conservation action.

"Naturalist identity doesn't just predict what people know or feel, it also predicts what they actually do," said Dr. CHEN Jin. "And a key part of that process is the feeling that you ought to help."

The researchers suggested that fostering naturalist identity, particularly among young people, could be a powerful strategy for conservation education. Programs that build both recognition (e.g. being seen by others as a naturalist) and competence (e.g. learning to identify species or use field guides) may help to turn casual interest into lasting commitment.

"Our findings suggest that conservation education should go beyond teaching facts about biodiversity. It should encourage individuals to see themselves as people who can and should make a difference," said CHEN.
