For three years, the Pollinator Path has been providing food and habitat for a wide variety of pollinators and a "living laboratory" for the study of pollinators by students and the community.  We have studied what plants attract pollinators and adjusted our flower beds to encourage the maximum number of diverse pollinators throughout the season.  This summer we were rewarded with a confirmed sighting of the federally endangered rusty-patched bumble bee (Bombus affinis) in the flower beds outside Owens Hall!  (See the photo below)

Minnesota is one of only 13 states (and one Canadian province) that provides habitat for this species, which has seen dramatic declines in numbers in the past 20 years.

The Pollinator Path is a series of gardens, some planted to attract pollinators and some planted for aesthetic purposes. These gardens allow students, faculty, staff and visitors to study pollinator activity and learn how to support declining pollinator populations.

 

El Camino de los Polinizadores de St. Thomas

El Camino de los Polinizadores es una serie de jardines, algunos plantados para atraer polinizadores y algunos plantados por motivos estéticos. Estos jardines permiten a estudiantes, profesores y visitantes estudiar las actividades de los polinizadores y aprender cómo mantener sus cada vez más más pequeñas poblaciones.

Bess and butterflies aren't the only pollinators! Pollinators also include flies, wasps, moths, birds, beetles, bats, and other animals.

pollinator is any animal that assists in plant fertilization by moving pollen from the anther of a flower to the stigma of a flower. Pollinators include bees, butterflies, flies, wasps, moths, birds, beetles, bats and other animals. Most flowering plants, including many food crops, depend on pollinators for fertilization. Some plants depend on one specialized pollinator.

Research has shown that honey bees will easily travel 2 miles in search of food and can go as far as 6 miles.

Pollinators face significant threats. Habitats are lost to crops, paved areas and landscapes that are designed for humans rather than pollinators. Climate change and the use of pesticides, particularly neonicotinoids, also pose serious problems. 30% of the bee population in the U.S. has disappeared in the last five years. Scientists estimate that the monarch butterfly population has declined more than 70%. Although it is impossible to track all pollinator species, declines have been seen in other invertebrate and vertebrate species.


You can help support pollinators by planting native flowers that bloom at different times during the growing season; providing sources of water with platforms or graduated edges to prevent drowning; and offering spaces for nesting, such as bare, unmulched ground, piles of brush or man-made nests. Avoid using pesticides, particularly neonicotinoids. If you must use a pesticide, follow the instructions carefully. Start noticing pollinators and evaluating your landscape in terms of the way it supports them!

Honey bees do not hibernate, but bumble bee queens do. Planting early spring flowers will give new bumble bee colonies important food.

Pollinator Path - No Harm Icons - Food Food
  • Plant flowering plants that are known to attract pollinators. Pick from annuals, herbs, vegetables, perennials, and flowering shrubs and trees.
  • Plant a variety of plants that bloom from early spring through late fall to feed pollinators for as long as possible.
  • Replace sod with flower beds OR seed flowering groundcovers into the lawn, such as clover.
Pollinator Path - No Harm Icons - Water Water
  • Provide sources of water in shallow, graduated-edge saucers or bowls so pollinators can stand at the edge and drink. Flat stones placed in a deeper birdbath can provide the right platform, as well as a bed of gravel in the bottom.
  • Many plants gather water on their leaves, including hostas, lady’s mantles, cup plants, sedums and water lilies.
  • A water-feature such as a pond or fountain will need water plants or stones to provide drinking platforms so the bees don’t drown.
Pollinator Path - No Harm Icons - Nesting Nesting
  • Ground-dwelling native bees need bare, unmulched ground, especially on south-facing slopes in well-draining soil. Do not use landscape cloth or excessive mulch.
  • Tunnel-nesting native bees need hollow stems or cavities in which to lay their eggs. You can make or buy native bee nests made from a variety of materials. You can also leave your perennials up all winter and let bees use the hollow stems for their eggs. If you must cut your perennials back, leave at least 16” of stem for the bees.
  • Debris-nesting bumble bees need dense piles of brush, grass or stones to provide a cavity sheltered from rain. A tidy yard is not a good habitat for bumble bees!

  • Refrain from using pesticides in your home and yard. Investigate alternate methods for managing pests.
  • If you must use a pesticide, do not use neonicotinoids, and be sure to follow all label instructions, especially those pertaining to pollinators. These include not using pesticides when bees are present or on flowering plants that will be visited by pollinators in the near future.

During summer 2018, Macalester College joined the Pollinator Path by designating site as their campus as pollinator beds.  Included in their sites are a prairie restoration area on their St. Paul campus and their Ordway Field Station.  These are great additions to the Pollinator Path!

In the future, we hope to establish a pollinator-friendly corridor between the two campuses and monitor pollinator movement along the corridor.

Sustainable Communities Partnership

The pollinator path is proud to participate in the Sustainable Communities Partnerships (SCP) from the Office of Sustainability Initiatives.  During Fall of 2017, we partnered with two courses, Intermediate Spanish I‌ (SPAN 211), taught by Susana Perez Castillejo and The Christian Theological Tradition (THEO 101), taught by Angela Senander.  The Spanish I course has provided the Spanish translations found on the site and the Theology 101 course chose the quotes from Laudato Si' which appear on the location descriptions pages. 

You can learn more about these projects on the SCP Project Page.
