    MNP-(Model for Nature Policy) Agrarisch : Uitwerking voor scenario’s uit de Natuurverkenning 2020
    Visser, T. ; Meeuwsen, H.A.M. ; Melman, Th.C.P. - \ 2019
    Wageningen : Wettelijke Onderzoekstaken Natuur & Milieu (WOt-technical report 159) - 64
    Models have been developed to calculate the impact of different policy scenarios on nature in agricultural areas. These models treat abiotic/landscape factors and management regimes separately. First, separate maps are made of the quality of separate abiotic factors. These maps are then integrated into a single map, describing the ‘potential quality’ of the landscape. Management is considered as a factor that determines the degree in which this potential quality is realised, resulting in a ‘realised quality’ map. The potential and realised habitats are differentiated into reproduction habitats and foraging habitats. The final suitability of these habitats is determined by their magnitude and spatial distribution. A brief description is given of how the model can be used to calculate different scenarios. This may be done by making changes in the factor maps (e.g. changes in landscape structure or drainage) or in the management map (e.g. intensification of the management regime).
    Basisbestand Natuur en Landschap
    Sanders, M.E. ; Meeuwsen, H.A.M. - \ 2019
    Wageningen : Wettelijke Onderzoekstaken Natuur & Milieu (WOt-technical report 158) - 101
    In its work for studies by the Netherlands Environmental Assessment Agency (PBL), such as the Assessment of the Dutch Human Environment, the Environmental Data Compendium, the Natuurpact reflexive evaluation and the Nature Outlook, the Statutory Research Tasks Unit for Nature & the Environment (WOt N&M) makes use of various base maps of natural and semi-natural habitats, such as the Nature Base Map (BKN), the Land Use Database of the Netherlands (LGN database) and the map of habitat management types (Beheertypenkaart). The problem is that information derived from these maps can influence the indicators and model results used in the PBL studies and lead to inconsistencies between them. This report describes the design of a standardised procedure for compiling a Geodatabase of Nature and Landscape (Basisbestand Natuur en Landschap – BNL) that can be regularly updated. The BNL is a raster database with a resolution of 2.5 metres. It consists of several layers and is generated using a GIS script. The geometric basis of the map is Top10NL, which is considered to be a reflection of the true situation in the field. The management type map produced by the provincial governments (IMNaB) was used as a source database for the areas and types of natural and semi-natural habitats. This map is a key resource in Dutch nature policy for the allocation of subsidies for conservation management and for determining ecological quality. The aim is to obtain ‘Status A’ for the BNL under the WOT Quality Control system.

    In this project the effect of regular maintenance of road-verges and natural maintenance of the “Poelzone” on populations of pestinsects, their natural enemies and host plants has been studied. In the studies locations in the Poelzone the number of hostplants, natural enemies, pest species and neutral herbivores is slightly higher than in the regular managed road verges. The number of pest thrips individuals is lower than the number of neutral thrips species, but total numbers of thrips are higher in the regular managed verges. Pest species and natural enemies have been found on various host plant species, often on similar species. Thrips species and their natural enemies reach their maximum occurrence simultaneously. The studied locations along water banks have similar insect populations but are relatively rich in early flowering species. The studies locations in the Poelzone seem to have a slightly better balance between pest and regulating species compared to locations in regular managed road verges, but differences are small and in both management types pest species have been found. Suggestions for further research have been presented.

    acidity - kriging - pH - relevé - soil type - vegetation

    Question: To assess the acidification process, nationwide information about soil pH on a site level is called for. Measurements of soil pH may be used, however there are not sufficient measurements available to map soil pH nationwide on site level. Instead we developed a soil pH map based on vegetation data. Location: Natural terrestrial areas in The Netherlands. Methods: 271,693 vegetation plots were used to estimate average soil pH per plot with indicator values, based on field measurements, of plant species. By spatial interpolation average pH values between the plots, with the soil type, groundwater table and vegetation management type as ancillary explanatory variables we created a soil pH map. The map covers all terrestrial nature areas (all areas that are not built up areas, agricultural areas and infrastructural areas) in the Netherlands with a map resolution of 25 × 25 m2 raster cells. Results: The predicted pH of the map varied between 3.0 and 8.6 with standard errors between 0.13 and 0.93. Most of the standard errors range from 0.4 to 0.55, with an average just below 0.5 pH unit. Cross-validation shows that for 33% the difference between observed and predicted is between −0.1 and 0.1 pH-unit and for 83% the difference is between −0.5 and 0.5 pH-unit. Validation shows that the pH map is unbiased (mean error is almost zero), accurate (root mean squared error is 0.64) and nicely captures spatial patterns (r = 0.77). We applied the pH map to assess the impact of acidification on the abiotic quality of nature areas in the Netherlands. Conclusions: The model fit in the predicted soil pH is in good resulting in a low standard error and a high correlation. The measures taken to prevent acidic deposition causing further acidifying of nature areas can be considered as successful.

    HappyHier: hoe gelukkig is men waar? : gegevensverzameling en bepaling van de invloedvan het type grondgebruik, deel II

    Dit onderzoek is uitgevoerd om de invloed van het type grondgebruik op hoe gelukkig mensen zich op een bepaald moment voelen te meten om zo rekenregels te formuleren waarmee het effect van ruimtelijke veranderingen en ingrepen op dit welbevinden is te kwantificeren. Daarbij gaat het met name om bebouwd gebied versus meer natuurlijke omgevingen, en om verschillen tussen de diverse typen natuurlijke omgeving. Om de gegevens te verzamelen, is een smartphone app ontwikkeld en uitgezet onder een groot publiek, waarbij mensen op locatie gevraagd werd aan te geven hoe ze zich voelden. Tijdens de periode van één mei tot 28 juli 2016 hebben 4318 unieke deelnemers gebruik gemaakt van de HappyHier app, dat wil zeggen ze hebben ten minste één vragenlijst op locatie ingevuld. In 2017 is het eerste deel van de analyses gerapporteerd, vooral gericht op verschillen in geluksgevoel per type omgeving (grondgebruik). In dit tweede deel wordt nader ingegaan op de representativiteit van de verzamelde gegevens, de tijd die men doorbrengt in de verschillende typen omgeving en de relatie tussen momentaan geluk en levenssatisfactie.---The aim of this research was to measure the influence the type of environment (land use) has on people’s reported happiness at a certain moment in time, with a view to formulating rules for quantifying the effect of spatial changes on wellbeing. The study focused on differences between built-up areas and more natural environments and between different types of natural environment. A smartphone app, called HappyHier, was developed for use by a broad sample population in the Netherlands, with push messages asking them to report how happy they felt at a certain moment. From 1 May to 28 July 2016, 4318 unique participants made use of the app, filling in at least one questionnaire on location. Part I of the report discussed the first part of the analysis, focusing mainly on differences in momentary happiness between different types of environment. Part II reports on the representativeness of the gathered data, the time spent in the diverse types of environment and the relationship between momentary happiness and life satisfaction.
    Beoordelen van de natuurkwaliteit in het Natuurnetwerk

    Om vragen over succes van natuurbeheer en –beleid te kunnen beantwoorden hebben terreinbeheerders en provincies een uniforme werkwijze voor het beoordelen van kwaliteit van de zogenaamde SNL-beheertypen gemaakt. Bij toepassen van de werkwijze bleek echter dat de natuurkwaliteit in sterke mate wordt bepaald door de gekozen gebiedsgrootte. In dit artikel wordt daarom een alternatieve methode voorgesteld.

    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.

    De cumulatieve impact van energie-infrastructuur kan een belangrijke rol spelen bij de populatieontwikkeling van kwetsbare soorten door sterfte en habitatverlies als gevolg van aanvaringen met die energie-infrastructuur of het verstorende effect van dergelijke infrastructuur. In dit rapport wordt een zo actueel en volledig mogelijk overzicht gegeven van de staat van kennis en de relatieve kwetsbaarheid van vogels, vleermuizen, zeezoogdieren en vissen in relatie tot de impact van windturbines, hoogspanningslijn
    en, waterkrachtcentrales en zonnepaneelvelden. Voor deze soortgroepen en energie-infrastructuur worden de kwetsbare soorten gerangschikt op basis van hun kwetsbaarheid en wordt inzichtelijk gemaakt waar de verspreiding van de kwetsbaarste soorten overlapt met de energie-infrastructuur. We evalueren hoe de cumulatieve impact van energie-infrastructuur op de soortgroepen gekwantificeerd kan worden nu en in de toekomst, en hoe die impact zich verhoudt tot andere antropogene drukfactoren voor de kwetsbaarste soorten. We bespreken mitigatie- en compensatiemaatregelen die in potentie kunnen voorkomen dat Nederlandse populaties van soorten afnemen als gevolg van de huidige en toekomstige energie-infrastructuur op zee en op land. Tot slot worden suggesties gedaan voor het opvullen van de belangrijkste kennishiaten en oplossingsrichtingen die het mogelijk maken de effecten op kwetsbare soorten bij de verdere groei van energie-infrastructuur op land en op zee te minimaliseren.

    This study explored the possibilities for developing a method to determine what nature combinations outside Natura 2000 areas can contribute to the realisation of conservation objectives for Birds and Habitats Directive (BHD) species. A total of 54 species were selected that represent the BHD conservation objectives and for which the area outside the National Ecological Network is relevant; these are considered to be target species. For 43 of these species fiches were compiled containing a description of the most important habitat characteristics. An attempt was made to obtain a picture of the potential nature conservation effects of nature combinations related to conservation objectives. Using the ecological characteristics of the target species, an adapted version of the Model for Nature Policy (MNP) was developed to predict potential habitat from GIS information and the changes in habitat size and quality that can be brought about by nature combinations. An initial set of calculations was made for four species, limited to the eastern central region of the Netherlands. To obtain useful information it would appear necessary to have GIS data at a high level of spatial detail. Technically the model works and the first impression is that the results are ecologically plausible
