Important Facts about Pollinator Decline

If we lost pollinators, a significant variety of foods would be affected. Many fruits rely heavily on pollinators, including: Apples, Berries (strawberries, blueberries, raspberries), Cherries, Peaches, Pears, and citrus fruits such as oranges, lemons, limes. Almonds, Hazelnuts and Walnuts are dependent on pollinators, and so are vegetables like cucumbers, pumpkins, squash and watermelon! Say goodbye to beans, along with herbs and spices like basil, cilantro and chives. The loss of pollinators would not only lead to the disappearance of these foods (and less delicious meals), but would also decrease the diversity and availability of many other food products, leading to nutritional deficits in human diets.

5. There Are Many Causes of Pollinator Decline

There's no single cause when it comes to the problem of pollinator decline. The reality is a number of different causes which are all connected. 

• Habitat Loss: Pollinator habitat loss is primarily driven by urbanization, agriculture, and land development, which reduce the availability of wildflowers and nesting sites. Intensive farming practices, including  monoculture cropping, further degrade habitats and diminish the diversity of food sources for pollinators. 

• Climate Change: Climate change negatively impacts pollinators by altering their habitats and disrupting the timing of flowering plants, which can lead to interruptions in food availability. Increased temperatures and shifting weather patterns also affect pollinator behavior, migration, and reproductive cycles. Extreme weather events, such as droughts and heavy rainfall, can further degrade their habitats and reduce their populations.

• Pesticide Exposure: Pesticide exposure poses a significant threat to pollinators, as these toxic chemicals can impair their ability to forage, navigate, and reproduce. Neonicotinoids and other harmful substances can cause lethal effects or impacts  such as disorientation and weakened immune responses. This exposure not only leads to declines in pollinator populations but also disrupts the vital ecosystem services they provide.

• Disease: Pollinators are threatened by diseases and pathogens  such as viruses, bacteria, and fungi, which can weaken their immune systems and lead to high mortality rates. For example, honeybees are particularly vulnerable to the Varroa mite, which spreads viruses and can devastate entire colonies. These diseases can spread rapidly, especially in stressed or crowded conditions, further contributing to the decline of pollinator populations and disrupting the ecosystems they support.

• Invasive Plants: Invasive plants can negatively impact pollinators by outcompeting native flora for resources, thereby reducing the availability of essential food sources like nectar and pollen. These non-native species lack the ecological relationships that native plants provide, leading to a decline in habitat quality for pollinators. Invasive plants can also disrupt local ecosystems, altering the dynamics between pollinators and their habitats and contributing to further declines in native pollinator populations.

Pollinator Conservation: What You Can Do To Help

Here's the good news: there are many ways to reverse Pollinator decline! One of the simplest actions is to create pollinator-friendly gardens by planting native flowers, shrubs, and trees that provide food, habitats and shelters throughout the seasons. Reducing pesticide use in gardens and yards can also make a significant difference; opting for organic pest control methods (such as cinnamon, garlic or even peppermint!) protects pollinators from harmful chemicals. Readers can support local beekeepers by purchasing honey and other bee products, as well as participating in community efforts to restore habitats, such as planting wildflower strips or participating in clean-up events in local parks.
