Effect van kleine landschapselementen en buitenlandse natuur op het duurzaam voorkomen van soorten in de provincie Limburg : Doorrekening met het MNP

In the Dutch province of Limburg not all natural areas are accounted for by the Model for Nature Policy (MNP) when assessing the realized nature targets in the Dutch Nature Network, for example in the studies for the evaluation of the ‘nature pact’ or Dutch governmental nature policy. Also the province has a long border with Germany and Belgium and the effect of their natural areas is not included in the evaluations. The MNP was therefore applied to calculate the effect of nature outside the official Nature Network and foreign nature on the viability of populations and species. When Limburg alone is assessed the viability of species and populations increases, especially if the extra natural areas are included. However, on a Dutch nation-wide scale the effects of both extra nature and foreign nature on species viability is negligible. This is due to the fact that the species that benefit in Limburg are already viable on a Dutch scale. The number of viable populations does increase, also in a national scale
