What are High Nature Value Farmlands and what is their role in rural development?
High Nature Value Farmlands (HNVF) are situated in rural areas where traditional farming is the main economic activity and a key factor in nature conservation. They are characterised by the presence of natural and semi-natural vegetation (grasslands), generally very species-rich, and in some cases they are integrated into a large scale continuous mosaic landscape which includes natural structural elements (such as field margins, hedgerows, stonewalls, patches of woodland or scrub, small rivers) and patches of arable land and orchards.
HNV farmlands in Romania are an estimated 30% of the total utilisable agricultural area: 5 million ha, associated with smaller holding sizes in hilly areas within the Carpathian arc.
Traditional farming practices are responsible for maintaining many of Romania’s (and Europe's) HNV farmlands, which deliver a host of public benefits (goods and services), including valuable cultural landscapes, high quality water and food, quality of life, recreation opportunities, carbon sequestration, flood control. These benefit wider society, beyond the communities that live within HNV areas.
HNV farmlands are also worthy of support for their economic and agricultural productivity which secure the livelihoods of many farming communities in Romania. Support given to HNV farmlands contributes to the prosperity of local communities, by providing opportunities for market diversification such as the development of rural tourism and businesses based on high quality and healthy products.
The key words for these landscapes are scale, mosaic and connectivity. These are the keystones of the remarkable biodiversity of the area.
The mosaic of habitats in this man-made landscape, a mixture of forest, grassland, scrub
and arable with many wildlife-friendly connecting features such as hedges, avenues and isolated trees, leads to extraordinary biodiversity.
Mosaic management offers a variety of habitats, and boundaries between habitats which are always very species-rich owing to the interaction where one habitat meets another. Mosaic management also means that when one area is harvested for hay, butterflies, young and adult birds, reptiles and amphibians can find refuge nearby. Studies have shown that 2 weeks after hay harvest, butterflies which have taken refuge nearby begin to
return to the mowed meadow as it regrows.
Connectivity allows fauna – small birds such as shrikes, larger raptors such as lesser spotted eagles, birds, small mammals such as dormice, larger mammals such as wolves and bears to move freely within larger feeding and breeding areas.
The scale of these intact, extensively managed, high mosaic/connectivity landscapes is vital for long term survival of large, genetically varied populations.
