Abstract
Equine yards represent a substantial yet often overlooked land-use category in Europe, with potential to contribute to biodiversity and environment conservation. This study explored behavioral drivers and barriers to biodiversity implementation on Dutch equine yards using the COM-B model (Capability, Opportunity, Motivation—Behavior). Semi-structured interviews were conducted with 19 yard owners, covering both private and commercial operations ranging from <3 hectares to >3 hectares. Data were analyzed thematically using a deductive COM-B framework, with coded responses quantified to assess the relative weight of barriers and enablers. Reflective motivation emerged as a consistent enabler, grounded in values such as equine welfare, sustainability, and responsible land use. However, barriers were more prevalent overall, particularly within physical and social opportunity. Small yards faced constraints related to time, labor, and land tenure, while larger yards reported challenges integrating biodiversity into routines and navigating regulatory complexity. Psychological capability was not a major constraint, though yard owners expressed a clear need for externally sourced, informed advice. These findings suggest that while motivation is high, structural barriers limit implementation. Unlocking the ecological potential of equine yards will require targeted, size-sensitive policy support, recognition of their land stewardship role, and better integration of biodiversity into daily management practices.
