After twelve years (2008-2019) the farmland bird index is 77.3 and the grassland bird index 62.6. The twelve year trend of farmland birds is moderate decline (the subgroup grassland birds have the same trend) in spite of the short-hand stabilisation in the last five years.
This indicator measures changes in populations of characteristic farmland bird species. The relative change (index) in the number of pairs is measured based on field surveys. According to our estimates, monitoring will allow us to follow long-term population trends, as monitoring is carried out on a large number of plots (110 plots in the period 2008–2016). These surveys are mostly carried out by local volunteers close to their homes. If there is no data for a certain year, it can be replaced with the data from a relevant statistical model.

Biodiversity Conservation Strategy of Slovenia
To maintain favourable state of all indigenous animal and plant species. (2.3)
To restore the ecological and social function of agriculture that contributes to the preservation of rural areas and high biodiversity in those areas and is based on sustainable farming practices and sustainable development of rural areas. (3.1)
The EU biodiversity strategy to 2020
TARGET 3: INCREASE THE CONTRIBUTION OF AGRICULTURE AND FORESTRY IN ORDER TO MAINTAIN AND ENHANCE BIODIVERSITY
3. A) Agriculture: By 2020, maximise areas being used for agriculture across grasslands, arable land and permanent crops that are covered by biodiversity-related measures under the CAP so as to ensure the conservation of biodiversity and to bring about a measurable improvement in the conservation status of species and habitats that depend on or are affected by agriculture and in the provision of ecosystem services as compared to the EU2010 Baseline, thus contributing to enhanced sustainable management.
