8:00 am - 4:00 pm
Event Details & Registration


Come to Walden Woods and help us reach the milestone of documenting 2,000 species in one day!

The Walden Woods Project, Minute Man National Historical Park, the E.O. Wilson Biodiversity Foundation, and local naturalist Peter Alden hope you will join us in a monumental effort to document as many species of living organisms as possible on July 6, 2019. We are celebrating Dr. E.O. Wilson’s 90th birthday and the 30th anniversary of BioBlitzes in Massachusetts with this special event.

Everyone is welcome at the Great Walden BioBlitz. For the general public, we will have guided walks in the morning at the Walden Woods Project in Lincoln, and un-guided walks at Minute Man NHP in the afternoon. General Public participants will be encouraged to explore Walden Woods using the free iNaturalist phone app to help document species. Scientists and taxonomic experts will pursue their work individually or in small groups in coordination with event organizers.

Pre-registration for Scientists and morning guided walks is required (afternoon walks at Minute Man NHP do not require registration).

When registering for the Great Walden BioBlitz, you will need to self-select which button to click below. Organizers will review credentials of scientists and taxonomic experts, so please provide full answers in the registration form.


For details on previous BioBlitzes in Walden Woods, in 1998, 2009, and at the Minute Man National Historical Park in September of 2018, see our Walden Biodiversity page here.

The iNaturalist app will be used by scientists and the general public throughout the Great Walden BioBlitz. It’s an exciting way to observe and record nature, where species identification is suggested based on an uploaded photo and identifications are confirmed by crowd-sourced experts on the iNaturalist platform. Learn about the app, download it, create an account and start recording observations!

This project is funded in part by a grant from the Freedom’s Way National Heritage Area.

Stewardship Lectures

The Walden Woods Project’s Thoreau Institute sponsors the Stewardship Lecture Series to celebrate innovation and creativity in environmental stewardship and to highlight the work of those who are promoting the values and ideas embodied by Thoreau. Each year the series features a number of talks, panel discussions, or media presentations featuring individuals at the cutting edge of a renewed environmental and social justice movement.

Recent Stewardship Lectures include:

  • Terry Tempest Williams, on her book The Hours of Land: A Personal Topography of American National Parks.
  • Laura Dassow Walls, in October 2016, gave the first public presentation of her biography, Henry David Thoreau: A Life, due out on July 12, 2017
  • David Gessner, All the Wild that Remains: Edward Abbey, Wallace Stegner, and the American West (on his book of the same title)
  • Robert M. Thorson, Walden’s Shore: Henry David Thoreau and Nineteenth Century Science (on his book of the same title)


We are always seeking excellent candidates for the lecture series and welcome any nominations and suggestions for the upcoming year. If you have an idea for a topic or presenter for our Stewardship Lecture Series, please contact the Walden Woods Project.

Modern Lyceum

“Thoreau’s Legacy: A Modern Lyceum” brings back the movement that spawned adult education in America with public forums that promoted thoughtful conversation and education about the social, intellectual and ethical questions of 19th-Century society. Guided by accomplished scholars on related topics, our Modern Lyceum will engage the public in an investigation of current social issues, with respect to and through the lens of Henry David Thoreau’s still-poignant writings and actions—incorporating many of his contemporaries.

Our Lyceum events will not seek to provide easy answers to today’s dilemmas and debates, but to highlight the way in which the voices and perspectives of the past can shed light on and help us to critically examine our current situation. We anticipate that our panelists will—all drawing from Thoreau’s texts and actions—come to slightly different conclusions to some very complex questions, and by doing so, broaden our perspectives on events of today.
