生态系统产品和服务的价值估计有助于为保护资源的分配提供理由，但不确定的估计有可能导致不可持续的资源分配。这里我们提出了重置成本作为昆虫授粉作为生态系统服务的更准确的价值估计，尽管这种方法也可以应用于其他服务。昆虫授粉对农业的重要性是不容置疑的。然而，这种服务主要是由野生传粉媒介（真正的生态系统服务）还是由管理传粉媒介（商业服务）提供，以及在传粉媒介减少的报告中，哪一种需要立即采取行动，仍然存在争议。如果作物授粉被用来支持生物多样性保护，那么应该明确区分人工授粉服务和野生授粉服务的价值。现有方法或低估或高估了传粉服务价值，并利用了受批评的一般昆虫和受管理的传粉媒介依赖因子。我们通过计算替代服务的成本来赋予服务价值的理论概念，作为评估野生和管理授粉服务的新方法。采用调整后的昆虫和管理传粉媒介依赖因子来估算南非西开普省落叶水果产业替代昆虫和管理传粉服务的成本。使用花粉粉和手工授粉作为合适的替代方法，我们对授粉服务的估值明显高于目前商业授粉的市场价格，尽管低于传统的比例估计。与授粉服务的包容性价值估计相关的复杂性需要几个可辩护的假设，但使估计比以前的尝试更具包容性。因此，本研究为持续改进特定环境的授粉服务价值估算提供了基础。
Value estimates of ecosystem goods and services are useful to justify the allocation of resources towards conservation, but inconclusive estimates risk unsustainable resource allocations. Here we present replacement costs as a more accurate value estimate of insect pollination as an ecosystem service, although this method could also be applied to other services. The importance of insect pollination to agriculture is unequivocal. However, whether this service is largely provided by wild pollinators (genuine ecosystem service) or managed pollinators (commercial service), and which of these requires immediate action amidst reports of pollinator decline, remains contested. If crop pollination is used to argue for biodiversity conservation, clear distinction should be made between values of managed- and wild pollination services. Current methods either under-estimate or over-estimate the pollination service value, and make use of criticised general insect and managed pollinator dependence factors. We apply the theoretical concept of ascribing a value to a service by calculating the cost to replace it, as a novel way of valuing wild and managed pollination services. Adjusted insect and managed pollinator dependence factors were used to estimate the cost of replacing insect- and managed pollination services for the Western Cape deciduous fruit industry of South Africa. Using pollen dusting and hand pollination as suitable replacements, we value pollination services significantly higher than current market prices for commercial pollination, although lower than traditional proportional estimates. The complexity associated with inclusive value estimation of pollination services required several defendable assumptions, but made estimates more inclusive than previous attempts. Consequently this study provides the basis for continued improvement in context specific pollination service value estimates.
