While cost estimation is a very positive tool for spatial conservation prioritisation, there are few examples where costs (in monetary terms) are applied. We present a repeatable method to estimate and map field values in monetary terms using common correlative models. We modelled, with a resolution of 1 km, the information obtained by several real estate's agencies with a set of eleven environmental, climatic, and anthropogenic variables. Land cover was the main influencing factor, but further variables were affecting bids on field sales according to the socio-economic specificity of each administrative province. The estimated values were related to endemic plant species richness, their conservation status and altitudinal ranges. Richest areas in endemics have lower values given current market conditions and, within these endemic rich areas, values near the coast were generally higher than the rest of endemic-rich territories. Despite their limits, our method offers an alternative perspective on the challenges of simplifying the extrapolation of useful information for planning and disseminating the conservation of many ecosystem services providers.
虽然成本估算对于空间保护优先化是一个非常积极的工具，但很少有将成本（以货币形式）应用的例子。我们提出了一种可重复的方法，使用常见的相关模型来估算和绘制以货币形式表示的实地价值。我们以 1 公里的分辨率模拟了由几家房地产代理机构提供的信息，其中包括 11 个环境、气候和人为变量。土地覆被是主要的影响因素，但根据每个行政省的社会经济特殊性，还有其他变量影响着农田销售的出价。估计值与特有植物物种丰富度、保护状况和海拔范围有关。在当前市场条件下，特有物种丰富的地区的价值较低，而在这些特有物种丰富的地区，沿海地区的价值普遍高于其他特有物种丰富地区。尽管存在局限性，但我们的方法为简化对规划有用信息的推断以及传播许多生态系统服务提供者的保护提供了一个替代视角。
