Airborne pollen records and their potential applications to the conservation of biodiversity

The magnitude and complexity of the current erosion of plant biodiversity call for the development of interdisciplinary tools that enable an early detection of its effects and the establishment of effective management strategies. Indeed, plant sciences face the complex task of identifying the ecological information needed for the conservation challenge. Along this line should be placed the approach of aerobiology to gather the essential information for the development of plant recovery guidelines. In this work, we aim to discuss the potential role of airborne pollen monitoring in providing relevant data for the protection of plants and its potential applications to the management of plant diversity. To this end, we review three study cases where aerobiological monitoring can provide significant insights on conservation science. The present study is a contribution to plant conservation biology through long-term aeropalynological sampling, on the basis that pollen records constitute a suitable indicator for evaluating resource conservation of vegetation responding to environmental fluctuations. In view of its position between botany and meteorology, the contribution of aerobiological knowledge to biodiversity conservation can be very relevant and should be explored thoroughly.
