    Natural areas are essential for species conservation and outdoor recreation. Where conservation and recreational values are under threat, site managers need to take measures to protect them. Scientific knowledge and tools might help them to predict the outcomes of planned measures and create support amongst stakeholders. To be accepted by all stakeholders the knowledge and tools must possess three attributes credibility, salience and legitimacy. In this PhD thesis existing scientific knowledge and tools were made context-specific and local measures were related to regional conservation targets for different study areas in the UK, Netherlands and France. The process of integrating site-specific data and local knowledge in the tools helps stakeholders explain their view of the local context and increases the salience and legitimacy of the knowledge and tools while their credibility is maintained. This leads to a co-learning process between recreation stakeholders, conservation stakeholders, managers and scientists where measures are supported by all parties involved.

    Het Ministerie van Landbouw, Natuur en Voedselkwaliteit (LNV) beoogt invulling te geven aan een lijst met diersoorten die door eenieder in of om het huis gehouden mogen worden (‘de Positieflijst’). Daartoe heeft LNV in de herfst van 2017 een groep onafhankelijke wetenschappelijk deskundigen gevraagd op persoonlijke titel te participeren in een Wetenschappelijke Adviescommissie Positieflijst (WAP). LNV heeft de WAP de opdracht verstrekt om te adviseren over een vereenvoudigde, wetenschappelijk valide, toetsingskader voor de positieflijst huisdieren. Randvoorwaarden hierbij zijn dat de systematiek voldoende goed uitvoerbaar is (eenvoudig, tijd- en kostenefficiënt) én dat de systematiek voldoet aan de Nederlandse en Europese wettelijke vereisten en aan wetenschappelijke validiteit. De taken van de adviescommissie bestaan uit:• het ontwikkelen van het toetsingskader;• het opstellen van inhoudelijke criteria als onderscheidende basis voor het toetsingskader;• de wetenschappelijke onderbouwing van de criteria van het toetsingskader;• de onderlinge weging van de criteria.Het resultaat van deze opdracht is een advies over een toetsingskader dat wetenschappelijk goed is onderbouwd en praktisch bruikbaar is om diersoorten naar potentiële risico’s te identificeren en vervolgens te ordenen. De systematiek dient te kunnen worden toegepast op zoogdieren, maar kan tevens als basis dienen voor de beoordeling van vogels, reptielen en amfibieën. LNV heeft de WAP gevraagd de intrinsieke waarde, zoals omschreven in de Wet Dieren, als uitgangspunt te nemen bij de ontwikkeling van het toetsingskader. Het welzijnsbegrip in het toetsingskader omvat, naast diergezondheid, ook de mogelijkheid om natuurlijk gedrag te vertonen en de fysieke integriteit. De beoordeling volgens het toetsingskader leidt tot een lijst van diersoorten die zijn gerangschikt naar potentiële risico’s voor dierenwelzijn/diergezondheid en voor gevaar (zoönosen, letsel) voor mens en dier.

    Acceptable change - Birds Directive - Impact - Statistical model - Visitor disturbance

    In protected areas managers have to achieve conservation targets while providing opportunities for outdoor recreation. This dual mandate causes conflicts in choosing between management options. Furthermore, the persistence of a protected species within the management unit often depends on how conservation areas elsewhere in the region are managed. We present an assessment procedure to guide groups of managers in aligning outdoor recreation and bird conservation targets for a regional scale protected area in the Netherlands. We used existing bird monitoring data and simulated visitor densities to statistically model the impact of outdoor recreation on bird densities. The models were used to extrapolate the local impacts for other parts of the area, but also to assess the impact on conservation targets at the regional level that were determined by the national government. The assessment shows impacts of outdoor recreation on Nightjar (Caprimulgus europaeus), Stonechat (Saxicola torquata) and Woodlark (Lullula arborea), reducing the regional population by up to 28 percent. The Woodlark population size was reduced below the level of the politically determined conservation target. The output of the regression models provides information that connects implications of local management to regional scale conservation targets. The spatial maps of bird densities can help in deciding where reducing visitor disturbance is expected to result in increasing bird populations, or where alternative measures, such as improving the habitat conditions, could be effective. We suggest that by using our assessment procedure collaborative decision making is facilitated.

    Argument - Conservation strategy - Stakeholder - Urban biodiversity - Urban bird conservation - Urban green

    Following the call from the United Nations Convention on Biological Diversity “Cities & Biodiversity Outlook” project to better preserve urban biodiversity, this paper presents stakeholder-specific statements for bird conservation in city environments. Based upon the current urban bird literature we focus upon habitat fragmentation, limited habitat availability, lack of the native vegetation and vegetation structure as the most important challenges facing bird conservation in cities. We follow with an overview of the stakeholders in cities, and identify six main groups having the greatest potential to improve bird survival in cities: i) urban planners, urban designers and (landscape) architects, ii) urban developers and engineers, iii) homeowners and tenants, iv) companies and industries, v) landscaping and gardening firms, vi) education professionals. Given that motivation to act positively for urban birds is linked to stakeholder-specific advice, we present ten statements for bird-friendly cities that are guided by an action perspective and argument for each stakeholder group. We conclude with a discussion on how the use of stakeholder-specific arguments can enhance and rapidly advance urban bird conservation action.

    In order to assess the significance of the presumed “umbrella effect” of Natura 2000 areas the European Commission initiated a study, in 2013, to address the following questions: 1) Which are, amongst the species regularly occurring within the European territory of the EU-28 Member States, those that significantly benefit from the site conservation under the EU Birds and Habitats Directive? 2) What is the percentage of all species occurring in the wild in the EU that benefit significantly from Natura 2000? 3) How significant is the contribution of Natura 2000 in relation to the objective of halting and reversing biodiversity loss? The approach used existing data, and covered the terrestrial mammals, birds, reptiles, amphibian, butterfly and plant species. The analysis is mostly based on statistical distribution models and GIS processing of species distribution data in relation to their presence within protected areas of the Natura 2000 network. The main findings for all species groups were: Animal species for which Natura 2000 areas were not specifically designated occur more frequently inside Natura 2000 than outside (in particular breeding birds and butterflies). These species do, therefore, gain benefit from the protected areas network. The species for which Natura 2000 areas were designated generally occur more frequently within the Natura 2000 site boundaries than the nonannex species; this is in particular the case for birds and butterflies, for amphibians and reptiles the difference is negligible. More specific conclusions and findings, as well as discussion of these results and implications for further studies are included in the report.

    This PhD study has evaluated hydrochars derived from biowastes as adsorbents for pathogen removal in water treatment. Pathogen removal experiments were conducted by carrying out breakthrough analysis using a simple sand filtration set-up. Glass columns packed by 10 cm sand bed supplemented with minor amount of hydrochar (1.5 %, w/w) were flushed with artificial ground water seeded with test microorganisms at an upward flow rate of 1 mL / min. Either back flushing or deionized water flushing was performed at pathogen retaining columns in order to investigate the pathogen removal mechanism of hydrochar-amended sand columns.

    Two home-made two-step reverse transcription-quantitative polymerase chain reaction assays were developed in order to quantify rotavirus in the samples from virus removal experiments. Since the total cost of the assays was mainly determined by the cost of reverse transcriptase, two reverse transcriptases with the lowest consumer price were employed. The efficiencies of home-made assays were comparable to a selected reference commercial kit in analyzing both environmental and laboratory samples, while the total cost of home-made assays was 11 times less. Though home-made assays necessitate more manual operations and time, the low-cost aspect might be appealing in those settings where the expenditure for consumables inhibits laboratories in their functioning.

    Hydrochars produced via hydrothermal carbonization of agricultural residue from maize or stabilized sewage sludge were evaluated for adsorptive removal of Escherichia coli. In order to improve the removal capacity, the hydrochars were activated by being suspended in 1M KOH solution (5 g hydrochar / L) for 1 h at room temperature. The activation improved the Escherichia coli removal efficiency from ~70 to ~90 %. In addition, successive detachment experiments carried out by performing back flushing or deionized water flushing into sand columns supplemented with maize-derived hydrochar indicated that the strength of Escherichia coli attachment increased by KOH activation. Also, Escherichia coli removal of sewage sludge-derived hydrochar was evaluated in larger column with 50 cm filter bed for 30 days of intermittent operation. 3 pairs of columns packed with either sand, raw hydrochar or activated hydrochar showed average removal efficiency of 36.5% ± 10.1 (n=60), 24.4% ± 10.5 (n=56) and 91.2% ± 7.5 (n=60), respectively. Idle time of filtration unit did not affect the Escherichia coli removal efficiency of hydrochar-amended columns. The results from material characterization attributed the enhancement in Escherichia coli removal induced from the KOH activation to development of macroporous surface with increased hydrophobicity and surface charge. It was apparent that the activation with the KOH solution removed tar-like substances from hydrochar surface, resulting in exposure of hydrophobic core and development of rough surface structure. Also, deposition of K+ ion in hydrochar was observed, which might have increased the surface charge.

    The removal of human pathogenic rotavirus and adenovirus was investigated using hydrochar derived from stabilized sewage sludge or swine faecal waste. Throughout virus removal experiments, rotavirus and adenovirus showed comparable removal. At 1 mL / min flow rate, raw hydrochar (without KOH activation) derived from either feedstock showed mean virus removal efficiency from 2 to 3 > log removal (99 - 100 %). Also flow rates of 2.5 and 5 mL / min were tested using faecal waste-derived hydrochar. The virus removal efficiency remained still high (2.1 log - 3 log) at the elevated flow rates. We speculated that the improvement in virus removal derived from hydrochar supplement is induced by provision of extra hydrophobic surfaces in sand column media. Regardless the type of packing material, successive deionized water flushing into virus-retaining columns released more rotavirus than adenovirus, indicating larger role of the secondary energy minimum in rotavirus retention. It was remarkable, because both types of viruses are similar in their shape and size. This observation provides evidence that virus transport-retention behaviour could be mainly determined by surface characteristics of virus rather than its size and shape. In this sense, the use of model virus needs to be carefully considered when performing water treatment or pathogen transport experiments.

    Successful removal of pathogenic virus using faecal waste-derived hydrochar highlights the potential of hydrothermal carbonization technology in less developed regions where modern water-sanitation systems are not affordable. Faecal waste, one of the most important pathogen sources, can be completely sanitized in elevated temperature and pressure during hydrothermal carbonization process. Moreover, the resulting hydrochar can be utilized at water or wastewater treatment. Despite general low-cost aspect of hydrothermal carbonization such as less energy dependency than dry pyrolysis and utilization of waste as a feedstock, the need for high-pressure reactor might hamper the implementation of the technology. Development of localized low-cost reactor, evaluation of hydrochar in its use at agriculture and/or energy production and overall economic analysis are recommended.

    The increased variability in weather as a manifestation of climate change is expected to have negative impacts on population survival in wildlife species, because it will likely lead to increased variation in vital demographic rates (mortality and reproduction) in these populations. For the effective protection of biodiversity, adaptation measures are needed to compensate for the expected increase in weather variability and the negative interaction with habitat fragmentation. As a case study, we studied the fluctuations in Great Bittern numbers (Botaurus stellaris) from 28 monitoring plots scattered over the Netherlands to explore the interaction between the effect of weather and possible remediating effects of the landscape structure. Great Bittern habitat surrounding these plots differs with respect to area, quality, and degree of isolation of this habitat. In western Europe, Great Bitterns are found to be susceptible to continuous loss of suitable habitat due to vegetation succession and fragmentation. Moreover, year-to-year fluctuations in local Great Bittern populations can be caused by severe winter weather or other weather extremes. Our results show that severe winter weather has indeed a significant negative impact on Great Bittern population growth rates. Furthermore, we found that an increased carrying capacity and spatial cohesion (i.e. inverse of habitat fragmentation) contribute to an increase in mean growth rates over the years. As growth rates are higher in large, well-connected habitats, we argue that recovery from negative effects of, e.g. severe winters on Great Bittern population numbers is enhanced in these less-fragmented habitats. We derived generic adaptation measures for enhancing the recovery rate of populations of species in general: one should invest in more large, well-connected nature areas, not only to diminish the negative effects of habitat fragmentation on wildlife populations, but additionally to reduce the impacts of climatic variability.

    Gegevens van de graadmeters ’actuele kwaliteit ecosysteem landnatuur’ en ‘gerichtheid milieu- en ruimtecondities voor duurzaam voortbestaan’ op soortniveau zijn gekoppeld om per soort een ruimtelijk bestand te genereren van gebieden die belangrijk zijn voor het behoud van de doelsoorten vlinders en vogels. Vervolgens zijn de resultaten van alle soorten geaggregeerd tot één ruimtelijk bestand over het belang van natuurgebieden voor soortbehoud. Daarbij zijn de soorten ingedeeld naar ecologische urgentieklassen. Soorten die actueel weinig voorkomen en die weinig potentieel leefgebied hebben in Nederland hebben de hoogste urgentieklassen gekregen. Soorten die momenteel veel voorkomen en veel potentieel leefgebied hebben, hebben de laagste ecologische urgentieklasse gekregen. Doel van het onderzoek is het verkennen van de meerwaarde van het combineren van de graadmeters voor beleidsevaluaties en verkenningen.
