nzes.pollination: Model pollination and honey bee potential hive density

In drexrichards/nzes: Modelling ecosystem services in Aotearoa New Zealand

Model pollination and honey bee potential hive density

Description

This function models floral resources for honey bee pollinators, following Ausseil et al. 2018 Ecological Applications

Usage

nzes.pollination(
  lcm,
  lcclasses,
  pollenlt,
  nectarlt,
  pollendemand,
  pollenrange,
  nectarrange,
  nectardemand = 200
)

Arguments

lcm	Raster of land cover classes as integer
lcclasses	Vector of land cover lookup classes in same order as lookup tables below
pollenlt	Lookup table of pollen production kgha-1 per 12 months
nectarlt	Lookup table of nectar production kgha-1 per 12 months
pollendemand	Vector of pollen demand per month kg. Must have one named value of "September"
pollenrange	Vector of pollen travel distance per month km
nectarrange	Vector of nectar travel distance per month km
nectardemand	Annual nectar requirement kg

Value

Raster stack indicating the annual carrying capacity in colonies per pixel and the annual pollinator density per cropped pixel. Layer 1+3 is the more conservative estimate using all months pollen to constrain. Layer 2+4 is using September as per Ausseil et al
