DESCRIPTION
Pollination services and pollinator diversity are essential in preserving food security and conservation of biodiversity. Bees are one of the very important pollinators. Besides the very well-known honeybees there are many other bee species that play significant roles.TRANSCRIPT

POLLINATION
pollen is transferred in the reproduction of plants, thereby enabling fertilization and sexual reproduction.
> 3/4 of food crops require pollinators
20% Abiotic
80% Biotic
Bees, butterflies, flies, bats, birds, rodents, etc.

HONEY BEE
Generalists
Rent out hives
Honey production
Some carry pollen
(for “building” – close, as pollen is collected
more quickly), others nectar (far).
Threat: mites, fungi, Colony Collapse Disorder

GOOD PRACTICES
FORAGING – NESTING - SHELTER
E.g.
Food sources
Create nesting sites
Corridors
Consider blooming seasons (pesticides)
