    Effects of heathland management on seedling recruitment of common juniper (Juniperus communis)

    Germination - Heathland - Juniperus communis - Liming - Rotavation - Seedling survival - Sod cutting

    Background and aims – Common juniper (Juniperus communis L.) is one of the most widespread woody species on the planet. Over recent decades, however, common juniper populations are decreasing in size and number in different regions. Lack of recruitment, caused by extremely low seed viability and the absence of suitable microsites for recruitment, is the key reason for this decline. For successful germination, the seeds need gaps in the existing vegetation and a soil with a relatively high base saturation. The aim of this study was therefore to assess how management actions such as sod cutting, rotavation and liming (alone or in various combinations) influence soil characteristics, seed germination and seedling survival of common juniper. Methods – We installed a sowing experiment across 104 1-m2 plots in four different sites in Belgium and the Netherlands using treatments with different combinations of fencing, sod cutting, rotavation, litter addition and liming. We determined how these treatments affected soil characteristics and how they influenced seed germination and seedling survival. Key results and conclusions – Across the whole experiment, germination rates of juniper seeds were very low (almost always < 1%). Our results confirm that bare ground promotes the germination of juniper seeds. Secondly, higher silt and lutum (clay) proportions in the soil and higher soil organic matter content seemed to have a positive impact on recruitment, possibly due to drought reduction. Management actions that negatively affect those soil characteristics, such as deep sod cutting, should thus be avoided in heathlands on sandy soils. Our results reveal a complex relationship between seedling recruitment success, soil conditions and management of common juniper populations. Overall, combinations of fencing, (superficial) sod cutting and liming or rotavation were most successful.

    The role of vegetation in Building with Nature pilot sandy foreshore Houtribdijk
    Lange, H.J. de; Huiskes, H.P.J. ; Groot, G.A. de; Penning, E. ; Steetzel, H.J. ; Fiselier, J. ; Ouwerkerk, S. ; Thiel de Vries, J.S.M. van - \ 2016

    The natural situation of foreshores in shallow lakes with a gradual slope, sometimes a sandy beach and a well-developed riparian zone (submerged macrophytes and helophytes) is quite rare in the Netherlands. Still, the various ecosystem services that natural foreshores offer, e.g. attenuation of incoming wave action and habitat for fauna, gives inspiration to innovative solutions. Especially the wave attenuation service has received attention as a viable alternative to conventional dike reinforcement. To increase our understanding of a constructed foreshore, we applied 70.000 m3 of sand along a 400 m long stretch of the Houtribdijk (Markermeer) during the summer of 2014, creating a foreshore with a gradual slope (1:30). The pilot was divided into four sections, two of which have an additional top layer of a sand-clay mixture to promote vegetation development. Each section was partially planted with selected wetland species, related to the possibilities and limitations to construct the desired abiotic environment. The vegetation is expected to deliver two ecosystem services related to flood protection: roots will prevent erosion of the sand, and aboveground biomass will dissipate wave energy. One of the chosen species is Common reed (Phragmites australis). To further enhance our understanding of the success of reed, we study the genetic diversity of Common reed in the Netherlands to identify if specific genotypes or phenotypes can be associated with its success at a given habitat. We present the first results of this genetic analysis and give advice on how this species can be promoted in newly constructed foreshores.

    Constructing notches in foredunes: Effect on sediment dynamics in the dune hinterland
    Riksen, M.J.P.M. ; Goossens, Dirk ; Huiskes, H.P.J. ; Krol, J. ; Slim, P.A. - \ 2016

    Measurements were carried out on the island of Ameland (The Netherlands) to determine whether notches cut into foredunes stimulated the supply of fresh calcareous beach and dune sand into the white and grey dune habitats behind the dunes, increasing these habitats' biological quality. Sediment characteristics and dynamics (deposition flux and grain size properties) as well as aspects of the vegetation (occurrence, composition and cover density) were studied along six transects, three behind an intact foredune and three behind a foredune with a notch cut into it. Compared to an intact foredune, the notched foredune exhibited higher deposition and accumulation behind the dune. The extra supply of sand was small, however, and for the notches studied, limited to the zone within approximately 50–60 m of the foredune's crest. Farther away from the dune, the effect of the notches became negligible. The presence of a notch did affect the grain size composition of sediment deposited behind the foredune. For intact foredunes, the grain size composition behind the dune was similar to that on the dune itself. When a notch had been cut, the sediment was finer behind the foredune, gradually coarsening away from the dune. Sand spray (deposition of sand eroded from the dune and transported in modified saltation during heavy winds) explains these granulometric results. The effect of the notches on the vegetation in the grey dune habitat behind the foredune was small and, for the notches studied, limited to the first approximately 35 m of the grey dune area, between 30 and 65 m from the foredune's crest. The notches had a greater effect on the white dune habitat but – in the opinion of the authors – this remained disproportionately small relative to the effort required for notch excavation and maintenance.

    In twee Natura 2000-gebieden werden in het kader van het verdrogingsnetwerk van de Provincie Overijssel locaties voor nieuwe grondwatermeetpunten geselecteerd. Hiertoe werden in de botanische hot-spots van deze gebieden elf transecten vegetatiekundig en bodemkundig beschreven. Op basis van bestaande gegevens werd een inschatting gegeven van de lokale hydrologische omstandigheden en hun representativiteit voor de regionale hydrologie. Belangrijke criteria bij de selectie waren (1) het goed ontwikkeld voorkomen van de habitattypen die voor bovengenoemde gebieden zijn aangewezen en (2) het voorkomen van deze typen in een zo gaaf mogelijke landschappelijke context.
    Does vegetation in restored salt marshes equal naturally developed vegetation
    Loon-Steensma, J.M. van; Dobben, H.F. van; Slim, P.A. ; Huiskes, H.P.J. ; Dirkse, G.M. - \ 2015

    Question: Do low stone dams built to prevent erosion and to restore salt marshes through increased sedimentation affect plant species composition? Location: Dutch Wadden Sea area (ca. 53°N 5°E). Methods: Relevés (N = 170) were made of the vegetation of two restored salt marsh sites on the barrier islands Terschelling (Grië) and Ameland (Neerlands Reid). Existing relevés of salt-marsh vegetation (N = 6198) made along the entire Dutch Wadden Sea coast (both the mainland and the barrier islands) were used as a reference. The vegetation of the two restored sites (Grië NLR data) was compared with the reference by (1) simple species-by-species analysis based on frequencies in both data sets, and by (2) ordination, where relevés of the restored sites were projected into a multivariate space defined by the species' abundances in the reference relevés. Results: Out of the 37 species that are common (i.e. have a frequency >5%) in either the Grië NLR data or the reference data, 31 have frequencies that differ by less than a factor of five, and 23 differ by less than a factor of two. Furthermore, the Grië NLR data occupy a space that is well in the centre of the ordination space defined by the reference data. Conclusions: There are no conspicuous differences between salt-marsh vegetation behind low dams and the vegetation that has naturally developed on unprotected mudflats. We conclude that measures targeting salt marsh development in view of flood protection do not interfere with nature conservation.

    De huidige vegetatie(structuur)monitoringmethoden voor de beoordeling van habitats zijn arbeidsintensief en kostbaar. De frequentie van de huidige vegetatiemonitoring is daardoor vaak laag en heeft het mogelijke risico dat de beheerder / beleidsmaker te laat in de gaten krijgt dat de kwantiteit of kwaliteit van een habitat achteruitgaat. Remote-sensingdata en -technieken bieden de mogelijkheid om sneller inzicht te krijgen in tussentijdse veranderingen. Hoewel de ontwikkelingen in Remote Sensing (RS) snel gaan, worden deze technieken nog maar weinig ingepast in de huidige werkprocessen.
