When a conservation land trust acquires a piece of land for less than the estimated fair market value of that land, it means that the landowner offered a "bargain sale" to the land trust, effectively donating part or all of his land.
Understanding what drives bargain sales could help conservation organization design more cost-efficient strategies, capitalizing on those indirect conservation dollars. Bargain Sales could also explain part of the discrepancy sometimes observed between regions defined as priority areas and regions where conservation actually happens. Having a clearer understanding of this could help correct conservation practices and/or change the practical definition of priority regions.
