The concept of potential natural vegetation: an epitaph?
Journal of Vegetation Science, 2010 We discuss the usefulness of the concept of Potential Natural Vegetation (PNV), which describes the expected state of mature vegetation in the absence of human intervention. We argue that it is impossible to model PNV because of (i) the methodological problems associated to its definition and (ii) the issues related to the ecosystems dynamics.We ...

Plant diversity across five vegetation belts in the Pyrenees (Catalonia, Spain) [PDF]
, 2012 In this paper we analyze the size and habitat partitioning of the vascular floras of five areas of the NE Iberian Peninsula, representing five distinct vegetation belts and three floristic regions: Mediterranean (basal belt), medio-European (submontane ...

A Unifying Concept for Growth Trends of Trees and Forests – The “Potential Natural Forest”
Frontiers in Forests and Global Change, 2020 Changes in the environment will alter the growth rate of trees and forests. Different disciplines assess such growth rates differently, for example, with tree-ring width data, forest inventories or with carbon-flux data from eddy covariance towers.

Assessing Vegetation Heritage Value: The Alentejo Central (Portugal) as a Case Study
Land, 2021 Vegetation natural heritage can be valued in itself, but also as a habitat for many wildlife species. This study presents a methodological essay concerning the evaluation of plant heritage, applied in Central Alentejo, in the south of Portugal.

Soil Response to Agricultural Land Abandonment: A Case Study of a Vineyard in Northern Italy
Agronomy, 2021 Agricultural land abandonment is an emerging problem in European Union (EU), and about 11% of agricultural EU land is at high risk of abandonment in the coming 10 years. Land abandonment may have both positive and negative effects in ecosystems.

Modeling the potential natural vegetation of Minnesota, USA
Ecological Informatics, 2017 Abstract Assessing the effects of human land use and management decisions requires an understanding of how temporal changes in biodiversity influence the rate of ecosystem functions and subsequent delivery of ecosystem services. In highly modified anthromes, the spatial distribution of natural vegetation types is often unknown or coarsely represented
