About us

Since 2000, Plants of Concern volunteers and staff have monitored and assessed trends in rare plant populations in the Chicago region. We collaborate with public and nongovernmental conservation agencies, landowners, and volunteer groups. With over 280 species and 1100 populations monitored to date, POC is making significant progress towards four major program goals:

  • Collect standardized data on most of northeast Illinois’ known rare plant populations
    POC has collected data on 70% of the populations of listed (endangered and threatened) species known in Illinois, as well as on populations of 100 non-listed, regionally rare species.
     
  • Educate people about rare plants and rare plant monitoring
    Over 800 volunteers have been trained in POC protocol over the life of the program, and this number grows every year. We retain about 60% of our volunteer community scientists from year to year, and many of these valuable partners report to us that they learn about rare plants and local ecology from their participation in the program.
     
  • Collaborate with public and private landowners
    We’ve worked with 130 landowners, including forest preserve districts, departments of natural resources, land trusts, non-profits, and private landowners. We share plant population data collected at these sites with the landowners, creating a mutually beneficial partnership.
     
  • Engage researchers in analysis and use of POC’s long-term datasets
    The data collected by POC are a trove of valuable information, and we strive to partner with researchers who can help us learn more from it. Visit our Research page to learn about some of the scientists we’ve partnered with and what they’ve helped us learn.

The Race to Save Rare Plants

Plants of Concern (POC) volunteers help monitor the rarest native plants in the Midwest, including wildflowers, grasses, trees, and ferns —species that are in danger of disappearing from the landscape forever. Teams of community scientists visit hundreds of populations each year, counting plants, measuring population sizes, and evaluating threats. Then what?

Where Do POC Data Go?

The data are assessed and then shared with approved partners, including landowners, state agencies, and researchers. (Because rare plant location data are highly sensitive, POC and its partners must approve all data sharing). 

Long-term monitoring data for plant populations provide critically needed baseline information to answer questions about why populations are rare and what drives population changes over time. In collaboration with researchers, we continue to delve more deeply into the complex dynamics of rare plant populations. See our Research page for more information about these important partners.

What Do POC Data Tell Us?

Since 2000, more than 280 species have been monitored by POC community scientists, partners, and staff. What do these data tell us? Find out more about the background and ecology of select rare species and how POC volunteers have helped them.

This video, produced by the Chicago Botanic Garden, showcases native Illinois orchids and Plants of Concern's role in monitoring them.


 

Research

Plants of Concern volunteers are an essential part of a team that includes scientists and researchers. The research team includes a wide range of specialists, including a molecular ecologist at the Chicago Botanic Garden and a doctoral candidate who studies rare plant conservation.

Holly Bernardo

Holly Bernardo is a Ph.D. student at Washington University in St. Louis. She studies rare plant conservation from multiple angles. In her collaboration with Plants of Concern, she is conducting viability analyses on a range of rare plants in Illinois. She has three goals for this project:

  1. To compare the viability of state protected (endangered and threatened) versus nonprotected rare species;
  2. To determine what characteristics of a rare species make it more or less likely to receive protection status (e.g. restricted geographic range, habitat specific);
  3. To determine if the characteristics that make a rare species more likely to receive protection status accurately predict the species most in need of protection status (i.e. those with the greatest risk of extinction).

This work will result in detailed population viability assessments of many rare Ilinois plants that can be used to further the conservation efforts of those species and their habitats.

Jeremie Fant, Ph.D.

Jeremie Fant is a molecular ecologist at the Chicago Botanic Garden who is interested in the genetic diversity of rare species. Even though we tend to think of them as a collective group, every rare species has very different reasons for its rarity. So although Dr. Fant’s work focuses on genetic data, he believes that field data is an invaluable component of all his studies, helping to ensure that the biology and ecology of the species inform the outcomes of the genetic analysis. He has worked with Plants of Concern on a number of species including Cirsium hillii, Asclepias lanugunosa, Castilleja sessiliflora, and Ammophila breviligulata. Visit his research webpage.

The following is a list of his publications that includes Plants of Concern data:

Dan Fink

Dan Fink has been a Plants of Concern monitor since 2010. He has a master’s degree in geography and environmental studies from Northeastern Illinois University. Bogs and their associated plant communities, particularly carnivorous plants, fascinate him. These interests led him to become a monitor for Plants of Concern. Monitoring northern pitcher plants (Sarracenia purpurea) for Plants of Concern influenced his master’s thesis topic selection. In 2012, with the support of POC, he completed his thesis “The Geographic Distribution of Sarracenia purpurea in Illinois and its Associated Species.” His research culminated in a census of all of the known sub-populations of the northern pitcher plant in Illinois and survey of the plant species sharing its habitat. This research now serves as a historic documentation of pitcher plants in Illinois, and also illustrates the importance of protection and management of the few sites where the plants are found.
