Vegetation (PNV) Map Layer (June 2022) The purpose of this guide is to introduce the user to the concept of Potential Natural Vegetation (PNV), the new PNV maps available at vegetation zone and subzone scales, and applications of the maps to address resource assessment and planning needs. This guide will accompany the PNV layer.

PNV is a classification system that uses indicator plant species to designate a biophysical environment (ecological potential) and infer a potential suite of ecosystem structures, compositions, and functions, through time. It integrates the climate, geology, geomorphology, soils, and vegetation in an area.

In ecology, potential natural vegetation (PNV), also known as Kuchler potential vegetation, is the vegetation that would be expected given environmental constraints (climate, geomorphology, geology) without human intervention or a hazard event.

2024年2月1日 · Potential Natural Vegetation (PNV) is the vegetation cover in equilibrium with climate that would exist at a given location non-impacted by human activities. PNV is useful for raising public awareness about land degradation and for estimating land potential. This dataset contains results of predictions of

It integrates the climate, geology, geomorphology, soils, and vegetation in an area.

2024年9月1日 · 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 comparison of their performance is still unexplored.

2019年5月15日 · Potential natural vegetation (PNV) and climate adaptation concepts should be integrated into revegetation programs to achieve sustainable ecosystems. The Yanhe Basin in the Loess Plateau of China (7687 km 2) has been subjected to intense human activity for centuries.

2023年7月1日 · To consider these temporal dynamics, we developed a modeling approach based on potential natural vegetation (PNV) corresponding to ecological contexts supporting vegetation succession. The assumption made is that modeling PNV better distinguishes biotope ecological niches, improving prediction accuracy.
