The iconic monarch butterfly has been added to the Red List of endangered species, but hasn’t received protection in the US yet. That’s not necessarily a bad thing.
Pollen brings seasonal misery to millions of Americans, but it serves a critical purpose: fertilizing many kinds of plants, including food crops.
Bees feeding in monoculture fields of single crops such as sunflowers crowd together and pass parasites to one another at high rates.

Huge single-crop fields attract bees in such numbers that they spread parasites to one another. Planting diverse mixes of flowers around fields helps spread out pollinators and keep them healthy.

Studies suggest that seeds coated with neonicotinoid insecticides may harm nontarget insects, mammals and birds. In response, states are starting to restrict use of these products.
Up to 85% of the nectar available to pollinating insects in a city comes from gardens. What we plant – whether in an allotment or a window box – can make a huge difference.
Armed with smartphones, keen eyes and curiosity, students are learning to provide vital observations that add to our knowledge of the distribution of plant and animal species and how to conserve them.
Half of all flowering plants mostly or completely rely on animal pollinators to make seeds. A decline in pollinators could cause major disruptions in natural ecosystems.

Honeybees are crucial for pollinating crops and plants. They need good forage resources to do this and these resources are under threat in South Africa.
