Farmland biodiversity is an important component of Europe’s biodiversity. More than half the continent is occupied by agricultural lands. They host specific habitats and species, which - in addition to their conservation values they provide - perform vital ecological functions. Indicators are needed to enable the monitoring of biodiversity at the farm level for the purpose of assessing the impacts of farming practices and of agricultural policies. Our research aims at identifying farmland biodiversity indicators which are scientifically sound, operational and relevant for stakeholders. We screened the literature for farmland biodiversity indicators and, in an iterative process with stakeholders, we identified 28 candidate indicators for genetic, species and habitat diversity. Those selected biodiversity indicators, as well as 14 management indicators that are known to relate to biodiversity, were assessed in 12 case study regions across Europe. Each case study region represents a typical production system (i.e. specialist field crops, horticulture and permanent crops; specialist grazing with cattle and other livestock types; mixed crop and livestock farming). In each region, 8-20 farms were randomly selected, mostly within the two groups of organic and non-organic farms, to obtain a gradient of farming intensity. Indicators were measured applying standardized sampling procedures and farm interviews. Sampling effort was recorded in order to assess the cost of indicator measurement. For each case study region, biodiversity indicators are presently being evaluated in conjunction with management indicators. Surrogate indicators will be proposed when possible and indicators will be prioritized taking into account their validity, practicality, cost and priority for stakeholders. Based on preliminary results, the presentation will focus on the specific challenges of farm level monitoring, addressing issues of sampling design within the farms and up-scaling from plot to farm to region. Part of this research was funded by the EU FP7 contract KBBE-2B-227161. For more information consult www.biobio-indicator.org

Experiments were set up over two winter seasons on golf greens i the Nordic countries. Two mowing heights in the autumn and one late application of 0.2 kg N /100 m2 were examined for effects on winter survival and turf performance in the spring. There were small effects from mowing height, but partly significant positive effects of fertilization. The results form annual meadow grass (Poa annua) were not consistent, but red fescue (Festuca rubra), creeping bentgrass (Agrostis stolonifera) and velvet bent grass (A.canina) accorded.

Forsøk gjennom to vintre på golfgreener i Norden viste lite effekt av økt klippehøyde om høsten, men positiv effekt av sen høstgjødsling; 0,2 kg N pr 100 m2 etter at veksten var avsluttet. Vinterskadene ble litt redusert og gresset ga et bedre inntrykk om våren. Det var forskjell på gressartene. Tunrapp (Poa annua) viste ikke klar respons på behandlingen, mens rødsvingel (Festuca rubra), krypkvein (Agrosis stolonifera) og hundekvein (A.canina) delvis ga signifikante resultater.
