Worms, birds and bees, these are a few of my favorite things. As a gardener and nature lover, I can’t imagine life without these three creatures. Each plays such an important role in creating healthy ecosystems and biodiversity. Without them, life wouldn’t be the same or possibly even exist. It sounds like a bold statement I know, but take the bee for example. It is single-handedly responsible for one third of the food we eat, including coffee and chocolate. Bees are directly responsible for the pollination of the plants that make them. What would I do without my bees?
Yet honeybees are in grave danger. A yet unexplained phenomenon known as “Colony Collapse Disorder” is decimating honeybee colonies around much of the world. The source of the problem has yet to be determined but it is strongly suspected that pesticides play a significant role.
On a related note, our beloved backyard birds are a welcomed addition to our gardens and landscapes. Their brightly colored plumage and melodic songs are the perfect complement to the plants and flowers we enjoy so much in our gardens. But in addition to the pure pleasure they provide to us personally, birds too play a vital role in maintaining biodiverse habitats. Many of our native plants are propagated each year thanks to seed-eating birds that randomly disperse them through ecosystems across the world. Birds are also a wonderful natural pest control since they eat millions of pest insects each year from our gardens and lawns. Unfortunately, according to the National Audubon Society, about seven million of our feathered friends die annually across America from eating insects poisoned by pesticides.
And then there is the lowly worm. Not so lowly really if you consider all that they do. They provide some of the most essential benefits to what happens below the surface of any garden or lawn. Known as “nature’s plow”, earthworms create a network of tunnels and pockets underground that allow air and water to circulate and roots to grow. Moreover, their castings (manure) are five times higher in nitrogen, seven times higher in phosphorus, and ten times higher in potassium than ordinary garden soil. A single acre of healthy earth may contain over a half million worms. But that number can fall rapidly when salt-based, synthetic fertilizers are added to the soil. Worms are very sensitive to adverse changes in soil chemical or physical makeup and will relocate to more hospitable environments.
All this to say that we gardeners and weekend warriors hold the key to protecting some of the most important guests we can ever have visit our gardens and landscapes. In order to provide the most inviting and sustainable environment for these vital creatures, understanding what attracts, repels and harms them will have a great deal to do, not only with the health and vitality of our own little corner of the world, but collectively, with the health of the planet as well.
