outline
Outline
  • Roussenski Lom Nature Park
    • Introduce key characteristics
    • Identify High Nature Value farmland
land use
Land use
  • Total area of Roussenski Lom Nature Park: about 3.400 ha
  • Planned extension to about 10.000 ha
land use5
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

    • 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
land use10
Land use
  • More semi-natural grasslands to be included in the enlargement of the park
  • Land outside park mainly farmland, vast majority arable land
land ownership in rlnp
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
land ownership in rlnp12
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
land ownership outside rlnp
Land ownership outside RLNP
  • Municipal ownership: >30%
    • semi-natural grasslands, forests
  • Private property: >60%
    • mainly arable land
hnvf concept
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
hnvf typology
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
key features of hnvf
Key features of HNVF
  • Always low-intensity
  • Always high proportion of semi-natural vegetation
  • Often a mosaic of habitats
hnvf analysis
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
hnvf analysis19
HNVF Analysis
  • Cultivated areas: arable land and vegetable gardens
hnvf analysis21
HNVF Analysis
  • Cultivated areas: arable land and vegetable gardens
hnvf analysis22
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
hnvf analysis23
HNVF Analysis
  • Natural grasslands in river terrace
hnvf analysis25
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

      • 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
hnvf analysis29
HNVF Analysis
  • Dry semi-natural grasslands on slopes
    • Most widely spread, most valuable
hnvf analysis30
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
hnvf analysis31
HNVF Analysis
  • Dry semi-natural grasslands on slopes
hnvf analysis32
HNVF Analysis
  • Dry semi-natural grasslands on slopes
hnvf analysis33
HNVF Analysis
  • Dry semi-natural grasslands on slopes
hnvf analysis34
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
hnvf analysis35
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
hnvf analysis36
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!
conclusions
Conclusions
  • High Nature Value farmlands present in RLNP, mostly situated in river terrace or in proximity of rocks
conclusions39
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
