Protecting Our Pollinators
Every garden requires pollinators, and bees are among the finest. Without them there would be limited flowers and far fewer fruits and vegetables. Did you know that about 30 percent of the food we eat depends on the pollination of bees, including onions, cashews, coffee, carrots, chocolate and vanilla? If we don’t protect these prolific pollinators, our landscapes, gardens and diets will be irrevocably changed.
Although there are many bees that are great pollinators, like carpenter, mining, sweat and cellophane bees, some of the most well known and easily identified bees are the honeybee and bumblebee. Both of these bees live in social colonies and are cavity nesters. Because these bees are active all summer long, they require a constant supply of floral nectar close to their hive and they thrive in flower gardens, orchards and other areas with abundant blooms.
Unfortunately, both these types of bees – along with many others – are disappearing rapidly, and two key threats are to blame.
- Habitat Loss: As more natural habitat is lost to development, there are fewer nesting locations and inadequate food supplies for bees. While meadows developed into resorts and parks disappearing for strip malls are obvious examples of development, other less visible developments that can hurt bees include widespread use of flower cultivars that do not produce adequate nectar, eliminating critical bee food sources.
- Pesticide Drift: Widespread, abundant spraying of pesticides to protect crops, lawns and parks can inadvertently hurt bees. Stronger pesticides can kill bees directly, while less potent toxins can contaminate nectar and will gradually build up to fatal levels in bees’ systems. Even if pesticides are not sprayed in areas where bees are abundant, high level spraying can easily be spread by wind patterns into critical bee habitats.
Inviting Bees to Your Garden
Fortunately, it is easy to bring more bees to your garden and encourage healthy bee populations. To support local bees…
- Planting a variety of flowers that will bloom throughout the entire summer to provide ongoing food supplies.
- Opt for native flower varieties that will be more easily recognized and used by bees, instead of introduced flowers that are less familiar.
- Eliminate chemical use in your yard, as much as possible, including on your lawn, garden and trees, especially while plants are in flower.
- Provide bees a safe place for shelter and to lay their eggs. A wood pile is suitable, or you can invest in a specialized bee house.
- Make sure that there is an available water source for your bees. A bird bath or any simple water basin works just fine.
