Bees are extremely important to us and our environment because
they are fabulous pollinators, giving us a wide array fruits, veggies,
beautiful flowers and much more. When people think about bees most tend to
focus on honey bees and large agricultural plots. However, the honeybee is just
one species out of roughly 450 in Missouri, such as Agapostemon virescens,
the metallic green sweat bee. Many people are beginning to consider community
gardens as reliable sources for their produce. Bees and gardens are important
in urban areas where the core is shrinking along with access to fresh produce
because they have the potential to provide food security for the local
communities. Unfortunately not much is known about bee communities, their
pollination services and how they react to urban environments. This is where
the lab of Dr. Gerardo Camilo comes in.
Our lab is looking at bee diversity within urban community
organic food gardens. We have been conducting a baseline survey in order to
figure out what species of bees may be at each garden. This is our lab’s first
year sampling multiple gardens with three located on the north side of St.
Louis city, including EarthDance, and three on the south side. EarthDance is
our most unique garden being that it is the largest and that it has a very
distinct surrounding habitat. We have sampled 80 species of bees total from all
gardens and 36 species total at EarthDance with six of these species sampled
exclusively at EarthDance!
Increased bee diversity within food gardens is important because
many species have their own preferences for certain flowers, have certain ways
of collecting pollen and may only be around for a short time each year. For
example, the bumble bee uses what is called buzz pollination; when the bee
lands on a flower it vibrates its wings in order to release the pollen. This
method is beneficial to crops such as cherry tomatoes due to the way the flower
is assembled, making it difficult for other bees to collect pollen and easy for
bees that use buzz pollination. Luckily for those readers who enjoy cherry
tomatoes, four species of bumblebee have been sampled at EarthDance like Bombus
impatiens, the common eastern bumblebee to the right.
We hope to use the information found in our survey to develop
research questions and goals and to better understand how to provide for urban
bee communities which will translate to a better understanding of how to best
provide for people living in the urban core. Increase in bee diversity will
lead to an increase in pollination services, leaving plants with bigger and
better quality fruits and vegetables. There is potential to use bees and their
services to transform these urban food deserts to flourishing food gardens.
