8.- SI – Satisfaction Index
The implementation of this BMP could have a positive influence on the farmer’s perception.
18.- Biodiversity surface area
Buffers could be a refuge for some species in which survival can be difficult in arable lands.
19.- Ratio between natural vegetation surface and total surface of the farm
Buffers will increase this ratio by making larger the natural vegetation surface (if this kind of vegetation is the one used in the buffer).
21.- Biodiversity structure(nests, hives, spider webs, etc.)- habitats
As buffers act as refuges, there could be an increase of biodiversity structures.
23.- NO3 level – rivers
Buffers will function as filters and could minimise the value for this indicator.
24.- Use of PPPs in some farms close to water streams
By the placing of riparian buffers in the margins of the field and in the surroundings of water streams the possible contamination of the use of PPPs will be diminished in the water stream.
25.- GHG level
Plants acting as buffers are a sink for GHG.
