What is it about?
Forest surveys, especially national forest inventories, are evolving towards multipurpose resource strategies, expanding their scope in several directions including biodiversity assessment. This article focuses on the estimation of plant species richness that constitutes one of the most relevant biodiversity indicators in forest ecosystems.

Why is it important?
The purpose of this article is to raise awareness within the forestry community of the inadequacy of nonparametric estimators affected by massive negative bias due to the difficulty of sampling rare species, at the same time highlighting the appeal of a data integration approach that consists in exploiting lists of rare species compiled by purposive surveys to improve the sample-based estimates.
Perspectives
This approach paves the way for the practical integration of species richness assessment into forest inventories, thus meeting the technical requests to support modern multipurpose forestry.
