Dear deer? Maybe for now. People's perception on red deer (Cervus elaphus) populations in Portugal

The human dimension of wildlife is a subject of increasing interest, especially considering the potential impact of people's perceptions on decision-making concerning wildlife management and thus on species' distribution and abundance. This is particularly important for species that inhabit human-dominated landscapes, where conflicts are likely to arise. These conflicts typically emerge between different human collectives when their interests collide and thus an assessment of their perceptions is valuable. Throughout Europe, ungulates have expanded, and Portugal is no exception. The expansion of red deer (Cervus elaphus) comes with benefits (e.g. hunting opportunities), but also with costs (e.g. vehicle collision or damage to crops), that can shape people's perceptions of these populations. To assess perceptions of red deer populations in continental Portugal, we developed a questionnaire survey with three interest groups: general public, farmers and hunters (total n = 1532). Our results show that perceptions about red deer were generally positive with a high acknowledgement of deer benefits, which we link to a broad level of sympathy towards this species. In addition, farmers showed a higher concern with crop damage caused by deer than non-farmers. Nonetheless, a general lack of knowledge regarding wildlife was present, particularly among younger people, who are potentially more apart and disconnected from nature. Now is the time to implement preventive and mitigation measures - e.g. fencing, reduction of population density - which can be a small contribution to address this problem. The focus should be put on people's acceptance of the required strategies to manage deer populations (which can also include unpopular practices, such as hunting). For that, an evaluation of people's attitudes towards deer populations and awareness of associated problems is essential. People's opinions, as well as the success of monitoring and management strategies, should be evaluated through multi-disciplinary teams, that include natural and social scientists, to ensure their success.
