Abstract
In het kader van het Additioneel Programma
Verzurings-onderzoek werd tien jaar onderzoek uitgevoerd in de Douglas
opstand Speulderbos. Het doel van dit onderzoek was het bepalen van de
blootstelling en belasting van verzurende en eutrofierende stoffen, en de
schadelijke invloed ervan op de vitaliteit van de Douglasbomen en het gehele
bos-ecosysteem. Hiervoor werd onderzoek uitgevoerd naar de
concentratieniveaus en depositieniveaus van verzurende componenten en ozon ;
de boskarakteristieken ; de groei- parameters ; de nutrientenstatus en de
effecten van een reduktie van de belastingen met behulp van
manipulatie-experimenten. In dit rapport zijn de resultaten van 10 jaar
onderzoek gebruikt om de causale verbanden tussen blootstelling en belasting
en effecten te bepalen. Hiervoor werden specifiek voor het Speulderbos
zogenaamde 'critical levels' en 'critical loads' afgeleid, evenals de
ontwikkeling in de overschrijding ervan. Deze overschrijdingen werden
vergeleken met de geobserveerde effecten, welke gedefinieerd zijn als
ecosysteem-veranderingen als gevolg van
milieubelastingen.
Within the framework of the Dutch Priority Program on Acidification, 10 years of research was conducted at the Douglas fir Speulder forest. The aim of the combined research was to determine the exposure and loads of acidifying and eutrophying pollutants, as well as their harmful influence on the vitality of Douglas fir trees and the forest ecosystem as a whole. Research was conducted to establish the levels and loads of acidifying pollutants and ozone, to determine forest characteristics and follow growth parameters and nutrient status in time and to determine the effects of reduction of loads and levels by manipulation experiments. In this report the results of 10 years of research are used to assess the causal relation between loads and levels on the one hand and effects on the other. For this, critical levels and critical loads were determined specifically for the Speulder forest, and the evolution of its exceedance was assessed. These exceedances were compared to the observed effects, which are defined as ecosystem changes as a result of environmental impacts.
