1 Natura 2000 in the Netherlands John Janssen Alterra, Wageningen (NL)

2 The Netherlands Atlantic biogeographic region Estuary of Rhine and Maas –Large diversity of habitats –High population density Landscapes: –Marine area –Coast –Large lakes –Low marshlands –Riverine area –Sand ridges (glacial, rivers) –Calcareous hills

3 Natura 2000 habitats and species 52 habitat types Annex I 36 species Annex II 95 birds Annex I (breeding & migrating)

4 Natura 2000 habitats and species Lithuania: also 52 habitat types

5 Marine area Harbour porpoise (Phocoena phocoena)

6 Coastal area



9 Large lakes Cygnus bewickii

10 Lowland marshes

11 Lowland marshes (endemic subspecies) Microtus oeconomus arenicola Lycaena dispar batava

12 Rivers


14 Glacial hills: heathland

15 Glacial hills: “Atlantic deserts”

16 Bogs

17 Calcareous hills


19 Nature conservation Nature Conservation Organisations (NCO’s) –State Forest Department 1899 –National Private NGO (Natuurmonumenten) 1905 –Provincial Private NGO’s (12) 1950-1960 –Private nature areas –Farmland Own & manage nature reserves Management activities in nature areas (finances by government, members & sponsoring) –Traditional farming: hay making, sod cutting, burning –Semi-natural grazing (extensively) –Guarding (birds) –Doing nothing  very rare ! (forests, marine areas) –Large restoration projects

20 Natura 2000: current status –Selection of sites –Natura 2000 database –National legislation –Conservation goals (July 2005)  –Formal assignment (2005, 2006) –Management plans (2006 …) –Monitoring + reporting (2007 …)

21 Designation process 1992: Habitat Directive 1996: 27 sites HD (282,000 ha) 1998: 89 sites HD  all larger than 250 ha 1999: Atlantic Seminar I (Kilkee, Ireland)  insufficient (ETC) * also sites smaller than 250 ha * some habitats/species: too little cover (20-80 %) 2001: Atlantic Seminar II (The Hague, NL)  still insufficient 2003: 141 sites HD (many smaller added) May 2003: sufficient  “first of the snails” (marine sites have to be selected later) Sept 2003: database Natura 2000 Bird Directory: 81, sufficient

22 Sites

23 Selection of sites Selection criteria: -Best 5 sites for each habitat/species (quality and/or quantity) -Best 10 sites for priority habitat/species –Broad (ecologically varied) habitats: subtypes (alliances) Best 3 sites for each subtype Best 5 sites for priority subtypes –Transboundary sites (Germany, Belgium) –Widespread species/habitats: no sites (protected within selected sites): Rhodeus sericeus, Cobitis taenia, 3270 Boundaries: –Location of habitats, habitat of species –Landscape ecological units / Administrative boundaries –Sometimes: smaller subunits (isolated patches) –Towns, large agricultural areas excluded

24 Boundaries

25 Natura 2000 database Best expert judgement In some cases based on hard data No basis for monitoring !!!

26 Conservation status Habitat Directive aims at Favourable Conservation Status SPECIES Natural range Population (size, trend, quality) Habitat Future prospects HABITATS Natural range Quantity (area) Quality (typical species, structure & function) Future prospects

27 Conservation status Not all species in favourable conservation status Conservation status is scored at a national level Scored all aspects, based on historical data/trends Also scored EU- responsibility Large amount Special species composition

28 Conservation status habitats (subtypes) species birds RED211325 AMBER361417 GREEN17553 UNKNOWN040 EU-resp. high351427

29 Conservation goals: national level Conservation status + EU-importance  national goal favourable  goal: conservation of present status unfavourable  goals which are in correspondence with a favourable conservation status: larger area, better quality, larger population, better structure & function, etc… Reference is based on historical data (circa 1950-1990) or on models (viable population, …) … has to be worked out in detail

30 Conservation goals: national level Example: 6120* Xeric sand, calcareous grassland EU-responsibility: high Sedo-Thymetum  nearly endemic Medicagini-Avenetum  nearly endemic Festuco-Thymetum serpylli

31 Conservation goals: national level < 1975 1975-2005 Data from: SynBioSys NL

32 Conservation goals: national level Goal: larger area, wider distribution, better quality - Strict protection remaining sites - More river dynamics (flooding, sand deposition) - Less eutrophication & management of sites

33 Conservation goals: site level For each habitat/species: National goal + relative importance of site + potential  site conservation goal Realization of site goals + outside Natura 2000  Favourable conservation status Relation with Water Framework Directive: Aims of WFD must support Natura 2000 aims

34 Conservation goals: site level Example: Zwarte water (1100 ha): floodplain of small rivers

35 Fritillaria meleagris


37 Conservation goals: site level 6510 Increased area and conservation of quality (in southern part of the area) 91F0 Increased area and increased quality

38 Management plans Have to be constructed for all Natura 2000-sites Detailed planning of conservation goals in space and time

39 Monitoring HABITATS Define favourable conservation status: Range: number of grids Area Typical species frequency in releves distribution grids Structure & function * 85 % of the sites in good condition

40 Monitoring HABITATS –range: distribution grids (whole country) –area: vegetation mapping (site level) –typical species from releves (within habitat types) national distribution grids (whole country) –structure & function: vegetation structure (from vegetation maps) indicative value of species composition (releves & permanent plots) measure of abiotic values (few locations) measure of abiotic values (national level)

41 Monitoring HABITATS Not for all habitat types the same Parameters Method Frequency of monitoring

42 Data sources SynBioSys NL(Alterra)  400.000 vegetation releves –Range –Quality (typical species; indicative value) Species distribution (NGOs) Vegetation maps, releves, Permanent plots (Nature Conservation Organisations) Advantage: many data Problem: many different organisations involved, different methods, different aims,…

43 Data sources Little known about some little species… Vertigo angustior
