Variable General Info
Pollinator abundance service score ?Comment:Relative abundance of each pollinator species/guild likely to travel from each nest parcel to forage on a crop in a crop for each agricultural parcel, resulting in the service map. |
Pollinator abundance source score ?Comment:This score represents the location and relative abundance of pollinators available for crop pollination from each parcel (x) resulting in the source map. |
Total pollinator abundance service score ?Comment:For each farm (and crop) the normalized pollinator score is calculated for all pollinator species/guilds, weighted by the background abundance of each pollinator in the landscape. |
