Quantifying landscape change with actual vs. potential natural vegetation maps

Phytocoenologia, 2003
This paper deals with landscape change in central Italy. Landscape abandonment is analyzed integrating a transition matrix approach with a symphytosociological method. A transition matrix brings the complete description of the temporal dynamics of a particular landscape over a given time period.

Quantifying the Impact of Global Climate Change on Potential Natural Vegetation

Climatic Change, 1999
Impacts of climate change on vegetation are often summarized in biome maps, representing the potential natural vegetation class for each cell of a grid under current and changed climate. The amount of change between two biome maps is usually measured by the fraction of cells that change class, or by the kappa statistic. Neither measure takes account of

A simulated map of the potential natural forest vegetation of Switzerland

Journal of Vegetation Science, 1993
AbstractUsing empirical data (ca. 7500 phytosociological releves), a simple, probabilistic ‘vegetation‐site’ model was developed, to simulate geographical distribution of 71 forest community types, representing the potential natural vegetation (PNV) of Switzerland. The model was interfaced to a geographic information system (GIS) and used to generate a

An outline and map of the potential natural vegetation of Ireland

Applied Vegetation Science, 1998
Abstract. A map of the potential natural vegetation of Ireland with an outline description of the vegetation units is presented. The vegetation of Ireland has a distinctive and highly oceanic character as a result of its location on the northwestern extremity of the Eurasian landmass and its recent geological and vegetation history.

The TRM Model of Potential Natural Vegetation in Mountain Forests

Folia Geobotanica, 2013
Due to advances in spatial modeling and improved availability of digital geodata, traditional mapping of potential natural vegetation (PNV) can be replaced by ecological modeling approaches. We developed a new model to map forest types representing the potential natural forest vegetation in the Bavarian Alps.

Long‐term vegetation stability and the concept of potential natural vegetation in the Neotropics

Journal of Vegetation Science, 2015
AbstractWhen vegetation trends over time are analysed from an appropriate long‐term perspective using palaeoecological records, the concept of potential natural vegetation (PNV) is unsupported because of continual vegetation changes driven by natural or anthropic forcings. However, some palaeoecological records show long‐lasting (i.e.

Quantifying the deviation of landscape diversity from potential natural vegetation with Shannon's entropy

Geobotanical mapping, 2002
In the past 20 years, several metrics have been developed to quantify various aspects of landscape structure and diversity in space and time, and most have been tested on grid- based thematic maps. Once landscape patterns have been quantified, their effects on ecological functions can be explained if the expected pattern in the absence of specific ...

The Impacts of Climate Change on Potential Natural Vegetation Distribution

Journal of Forest Research, 1997
Change in potential natural vegetation (PNV) distribution associated with climate change due to the doubling atmospheric carbon dioxide (2×CO2) was estimated with a global natural vegetation mapping system based on the modified Kira scheme to the globe and the continents.

Multi-model assessment of potential natural vegetation to support ecological restoration

Journal of Environmental Management
Ecological restoration is imperative for controlling desertification. Potential natural vegetation (PNV), the theoretical vegetation succession state, can guides near-natural restoration. Although a rising transition from traditional statistical methods to advanced machine learning and deep learning is observed in PNV simulation, a comprehensive ...
