Citizen Science Collaborations

Owl's Hill Nature Sanctuary is proud to contribute to state and national citizen science species population studies.  These long range studies advance our understanding of species population trends over space and time.  We encourage anyone interested in making an impact on our insight into the natural world around us to check out these organizations and others.

GET INVOLVED!  CURRENT Citizen Science Opportunities:

  A citizen science project in collaboration with Boston University's Department of Biology that aims to characterize how leaf traits within species vary throughout their geographic distributions. The focus is mainly on differences in nutrient concentrations of green leaves in the summer and freshly fallen leaves in the autumn.

They are currently recruiting volunteer citizen scientists throughout the United States to collect red maple (Acer rubrum) leaves from a tree in their local areas. . .once when the leaves are green and again at leaf fall. Leaf samples will then be sent to Boston University for processing and analysis. Click here for more information or to sign up.


ON-GOING Citizen Science Research Collaborations:

Image result for north american butterfly association

Owl's Hill volunteers participate in seasonal butterfly counts on the property and as part of a larger Nashville South count area that includes Warner Park, Radnor Lake, Cheekwood Botanical Garden, and Ellington Ag Center.  This national organization tracks butterfly populations to help scientists better understand the biology of butterflies and population trends.


Image result for monarch larva monitoring project

Dedicated volunteers monitor milkweed plants in an established plot to record weekly egg, larva, and adult monarch activity.  This is a small but important piece of this national study to understand and keep track of Monarch Butterfly population distribution and migration patterns.  This data is used to inform and inspire Monarch Conservation.

Owl's Hill volunteers participate in seasonal bird counts on the property and as part of a larger Nashville count area for this state organization.  TOS is dedicated to the protection and conservation of birds, as Owl's Hill is, and all data is used to better understand bird distribution, migration patterns, and population numbers.

The next Great Backyard Bird Count is February 14-17, 2020.

Cornell's Nestwatch program is a nationwide monitoring program designed to track status and trends in the reproductive biology of birds.  Data is intended to be used to study the current condition of breeding bird populations and how they may be changing over time.  Owl's Hill volunteers monitor and record weekly nestbox data on our over 35 nest boxes on property.
