Cattle Grazing Helps Pollinators in Sagebrush Rangelands
Periodic cattle grazing in sagebrush rangelands benefits ground-nesting bees by reducing plant litter and exposing bare ground for constructing nests, a study finds.

A new study analyzed crop yields of more than 1,500 fields on 6 continents, and found that production worldwide of nutritionally dense foods such as fruits, vegetables, nuts and legumes is being limited by a lack of pollinators. The study is timely given concern about global declines in insects.

Global Food Production Is Being Limited by a Lack of Pollinators
Researchers have analyzed crop yields of more than 1,500 fields on six continents and found that a lack of pollinators is limiting the production worldwide of important, nutritionally dense foods such as fruits, vegetables, nuts and legumes.

Even brief exposure to insecticide used in vaporizing commercial mosquito repellents can significantly impair bumblebees’ ability to find their way back to the nest. The bumblebee workers’ ability to navigate back to the nest with food is vital to the survival of the entire colony.

Insecticide in insect repellents impairs bumblebees’ ability to navigate
Even brief exposure to the insecticide used in mosquito repellents can significantly impair bumblebees’ ability to find their way back to the nest.
Bees pass the maths test: study confirms the insects aren’t just winging it. Honeybees do have the ability to process numerical information, finds study that addressed recent international debate over whether bees are truly assessing numbers or simply reacting to visual patterns.

🐝 In Nepal's Jumla district, pollinators are vital for diets and income. A study found they provide over 20% of vitamin A, E, and folate intake, and 44% of farming income for 120,000 residents.
📈 Globally, 3-5% of fruit, vegetable, and nut production is lost annually due to inadequate pollination. This loss is linked to an additional 500,000 deaths per year from malnutrition-related diseases.
🌍 Tropical regions like sub-Saharan Africa, northern South America, and south-east Asia are most vulnerable to crop pollination shortfalls from pollinator declines, risking human well-being.
🌿 Pollinators are essential for about 80% of the world's population relying on herbal medicine, with insects pollinating approximately 28,000 medicinal plants.
