Start a Phenology Walk or Trail

A Phenology Trail is a network of Nature's Notebook observation sites. Linked together, these sites provide the participant with places to visit, enjoy nature, collect data, and learn about supporting organizations. They provide researchers and managers a wealth of information about the phenology of local species of interest.   

You might want to start with a simple "Phenology Walk" at one location, with a pathway linking observation points together for data collection.  Each site has at least two species tagged for data collection.  Once you've established your Phenology Walk, recruit others in your community to do the same.  Then, you can link all of your sites using our groups functionality and create a Phenology Trail. A "Phenology Trail" is a series of Phenology Walks, or what we also refer to as Local Phenology Projects (LPPs) that may cover one location (depending on the size, if it is large, such as a National Park) or many locations. They key to this definition is that it includes a series of Phenology Walks or Local Phenology Projects, linked together.

Use this to celebrate the different ways we all engage in phenology observation on a daily basis. 

More information can be found on our Phenology Walk and Trail Planning Guide, linked in the table below. 

Why Create a Phenology Trail? 

  • Link local and regional phenology activities in a new way
  • Build connections between organizations with similar missions
  • Teach about the scientific method and native species
  • Use research data to answer local science questions
  • Create opportunities for more than one person to submit observations at a group site
  • Provide phenology and climate change education opportunities
