  1. High Nature Value farmland in Roussenski Lom Koen De Rijck - for EFNCP / WWF-DCPworkshop, 18-19 October 2007

  2. Outline • Roussenski Lom Nature Park • Introduce key characteristics • Identify High Nature Value farmland

  3. Land use • Total area of Roussenski Lom Nature Park: about 3.400 ha • Planned extension to about 10.000 ha

  4. Land use • 38% of RLNP: forest • Broad-leaf forests prevail • 44% of RLNP: agricultural area • Arable land (50%), semi-natural grasslands (19%), mix of arable and grassland with a lot of natural vegetation (22%) • 13% of RLNP: transitional woodland/shrub

  5. Land use • 38% of RLNP: forest • Broad-leaf forests prevail • 44% of RLNP: agricultural area • Arable land (50%), semi-natural grasslands (19%), mix of arable and grassland with a lot of natural vegetation (22%) • 13% of RLNP: transitional woodland/shrub • 2% of RLNP: natural grasslands

  6. Land use

  7. Land use

  8. Land use • More semi-natural grasslands to be included in the enlargement of the park • Land outside park mainly farmland, vast majority arable land

  9. Land ownership in RLNP • State ownership: 76% or 2.600 ha • Municipal ownership: 12% or 400 ha • Private property: 9% or 290 ha • Other ownership: 1% or 35 ha

  10. Land ownership in RLNP • State ownership: 76% or 2.600 ha • almost all in State Forest Fund • Municipal ownership: 12% or 400 ha • half in State Forest Fund • Private property: 9% or 290 ha • mainly out of State Forest Fund • Other ownership: 1% or 35 ha

  11. Land ownership outside RLNP • Municipal ownership: >30% • semi-natural grasslands, forests • Private property: >60% • mainly arable land

  12. HNVF Concept • High Nature Value farmland are those areas in Europe where agriculture is a major (usually the dominant) land use and where that agriculture supports, or is associated with, either a high species and habitat diversity or the presence of species of European conservation concern, or both

  13. HNVF Typology • Type 1: Farmland with a high proportion of semi-natural vegetation • Type 2: Farmland dominated by low intensity agriculture or a mosaic of semi-natural and cultivated land and small-scale features

  14. Key features of HNVF • Always low-intensity • Always high proportion of semi-natural vegetation • Often a mosaic of habitats

  15. Land use

  16. HNVF Analysis • Study done by Rosen Todorov Tsonev • Three classes of HNV farmland in RLNP: • Cultivated areas: arable land and vegetable gardens • Natural grasslands in river terrace • Dry semi-natural grasslands on slopes

  17. HNVF Analysis • Cultivated areas: arable land and vegetable gardens

  18. HNVF Analysis • Cultivated areas: arable land and vegetable gardens

  19. HNVF Analysis • Cultivated areas: arable land and vegetable gardens • Large-scale intensive monoculture on chernozem > no high nature values present • Vegetable gardens in river terrace > important for some animals e.g. Lanius collurio, but not for plants > HNVF Type 2

  20. HNVF Analysis • Natural grasslands in river terrace

  21. HNVF Analysis • Natural grasslands in river terrace • Widely spread in RL river valley • Along Cherni Lom (Pepelina - Cherven) and Malki Lom (Svalenik and Nisovo) of EU importance (6510 Lowland hay meadows) • Often on the place of abandoned fields > rich in nutrients • No special conservation value for plants, but important for many animals, e.g. Crex crex, Spermophilus citellus > HNVF Type 1

  22. HNVF Analysis

  23. HNVF Analysis • Natural grasslands in river terrace • Widely spread in RL river valley • Along Cherni Lom (Pepelina - Cherven) and Malki Lom (Svalenik and Nisovo) of EU importance (6510 Lowland hay meadows) • Often on the place of abandoned fields > rich in nutrients • No special conservation value for plants, but important for many animals, e.g. Crex crex, Spermophilus citellus > HNVF Type 1 • Scrub encroachment and nutrient levels are problems

  24. HNVF Analysis

  25. HNVF Analysis • Dry semi-natural grasslands on slopes • Most widely spread, most valuable

  26. HNVF Analysis • Dry semi-natural grasslands on slopes • Most widely spread, most valuable, several sub-types: • Pastures on loess heights and uplands • Rocky steppes • Mosaics of pastures and bushes on rock edges

  27. HNVF Analysis • Dry semi-natural grasslands on slopes

  28. HNVF Analysis • Dry semi-natural grasslands on slopes

  29. HNVF Analysis • Dry semi-natural grasslands on slopes

  30. HNVF Analysis • Dry semi-natural grasslands on slopes • Pastures on loess heights and uplands • Along Cherni Lom (Cherven – Tabachka – Pepelina), Malki Lom and Beli Lom (Pisanets – Vetovo) • Important orchid site, of European importance > HNVF Type 1 • Threatened by overgrazing • Rocky steppes • Mosaics of pastures and bushes on rock edges

  31. HNVF Analysis • Dry semi-natural grasslands on slopes • Pastures on loess heights and uplands • Rocky steppes • More rare, small areas on eastern Cherni Lom riverbank (Ostritsa – Tabachka) • Several rare and endemic plant species, e.g. Ruta graveolens, habitatof European importance (6240 Subpannonian steppes) • Mosaics of pastures and bushes on rock edges

  32. HNVF Analysis • Dry semi-natural grasslands on slopes • Pastures on loess heights and uplands • Rocky steppes • Mosaics of pastures and bushes on rock edges • Habitat of EU importance, with Carpinus orientalis • Potentilla emili-popii, Poygala sibirica (only population in BG between Koshov and Cherven), Verbascum diesckianum (Balkan endemic) • Close to Basarbovo and Bozhichen: Chamaecytisys kovacevii (Bulgarian endemic) • Partly in the State Forest Fund!

  33. Conclusions • High Nature Value farmlands present in RLNP, mostly situated in river terrace or in proximity of rocks

  34. Conclusions • High Nature Value farmlands present in RLNP, mostly situated in river terrace or in proximity of rocks • Many plant and animals species, including rare ones, are depending on low-intensity farming management • Threats of nitrate pollution, lack of mowing, overgrazing and undergrazing • Farmland in Roussenski Lom is biotope of European significance
