Pollinator Monitoring More than Pays for Itself

Resilient pollination services depend on sufficient abundance of pollinating insects over time. Currently, however, most knowledge about the status and trends of pollinators is based on changes in pollinator species richness and distribution only.

Systematic, long-term monitoring of pollinators is urgently needed to provide baseline information on their status, to identify the drivers of declines and to inform suitable response measures.

We evaluated the full economic costs of implementing four potential national monitoring schemes in the United Kingdom, based on power analyses that estimated sample sizes required to detect a 30% national scale change in pollinator populations over 10 years: 1) professional pollinator monitoring, 2) professional pollination service monitoring, 3) volunteer collected pan-traps and 4) volunteer focal floral observations. These costs were compared to: i) the costs of implementing separate, expert-designed, research and monitoring networks and ii) the...

韧性传粉服务有赖于一定时期内授粉昆虫（pollinating insects）种群数量的充足性。然而当前学界对传粉昆虫（pollinators）现状与变化趋势的认知，却仅基于其物种丰富度与分布范围的变化。

亟需开展系统性的长期传粉昆虫监测工作，以获取其种群现状的基准数据，明确种群衰退的驱动因素，并为制定合理的应对措施提供科学依据。

本研究基于效力分析（power analysis），估算了在10年内检测出英国（United Kingdom）传粉昆虫种群发生30%全国性规模变化所需的样本量，进而评估了四种潜在国家级传粉监测方案的全经济成本：1）专业传粉昆虫监测；2）专业传粉服务监测；3）志愿者采集诱捕盘（pan-traps）样本；4）志愿者开展目标花卉观测（focal floral observations）。随后将上述成本与：i）搭建独立的专家设计研究与监测网络所需的成本，以及ii）……进行了对比。
