Upcoming TREES Projects

2026 Fall Tree Planting at Rea Park
Saturday, November 7 | 9:30 a.m.
Join TREES Inc. for our annual fall planting at Rea Park, where major park improvements are nearing completion and a new spur of the Riley Trail is taking shape. Volunteers will help us add trees to this renewed community space.
Planting volunteers are needed. No experience is necessary—we’ll provide guidance and work together to get the trees in the ground.
Other Fall Volunteer Opportunities
We’re also planning two tree-care projects for this fall:
-
Tree Maintenance Day — We’ll return to one of our previous planting sites to remove stakes, prune lower limbs and mulch young trees.
-
101 Trees of Indiana Trail — Volunteers will help mulch and care for trees along this unique walking trail.
Dates and details are coming soon. Sign up through our volunteer form to let us know you’re interested, and follow TREES Inc. on social media for the latest project information.
Recent Tree Planting Projects

Tree Planting at Bicentennial Park, Nov. 15, 2025
On an unseasonably warm November 15, more than 175 volunteers—ages 5 to 75—came out in t-shirts to plant trees at Bicentennial Park and along the U.S. 40 corridor. The event marked Planting #2 in TREES Inc.’s 2025 Fall Planting Tour celebrating our 35th Anniversary, and it was made even more special through our partnership with RiverSCAPE and the Vigo County Parks and Recreation Department. Volunteers helped plant 75 native hardwood and understory trees in and around the new parking areas and walkways of Bicentennial Park, as well as along the route connecting the park to the Wabashiki Trail. Another 40 trees were planted in early December on the north side of U.S. 40 just across from the park. Reviving a Historic Vision For more than a decade, TREES Inc. and RiverSCAPE had dreamed of beautifying the area west of the bridge. This planting finally made that vision a reality—and it marked TREES Inc.’s first project outside the Terre Haute city limits. The site itself carries nearly a century of history. In the 1920s, the area was envisioned as Paul Dresser Memorial Park, a civic landscape anchored by a formal circular drive and framed by a grand “necklace” of sycamore trees—part of the historic emerald necklace, a 40-mile greenway designed by famed landscape architect George Kessler. Over the years, many of these sycamores were lost to storms and age. But on this November morning, volunteers helped “re-jewel the necklace” by planting 27 new sycamores, restoring a beloved piece of the community’s past. A Community Effort in Every Sense This planting brought together an enthusiastic mix of people: local families, Rose-Hulman and ISU students, the EARTHlings, North High School ROTC cadets, employees from GE Aviation and Elanco, AOPi and PiKA members, Riverscape volunteers, Vigo County Parks staff, and TREES Inc. members. Together, they transformed a former industrial area into a greener, healthier landscape. As volunteers dug, several unearthed small “archaeological treasures” from the area’s industrial past—a reminder of the layers of history beneath Bicentennial Park. Safety remained a priority, with gloves required for all and first-aid support readily available. Powered by Grants—and People This project was made possible through a $25,000 matching grant from the Indiana Department of Natural Resources Community Urban Forestry Assistance program. And the match wouldn’t have been possible without the volunteer hours donated by so many community members. A Milestone Year of Planting The Bicentennial Park event was one of three Fall 2025 plantings led by TREES Inc. Altogether, more than 300 new trees—representing over $70,000 in state, federal, and community foundation funding—were planted across Vigo County. Additional locations included the neighborhood south of Union Hospital, Ohio Boulevard, and Thompson and Brittle Bank Parks. Growing the TREES Inc. Community Many volunteers told us how meaningful it felt to look around—muddy, tired, proud—and see how 75 new trees and 175 neighbors could reshape a landscape in just a few hours.
Union Hospital Neighborhood, Nov. 1, 2025
More than 125 volunteers planted 100 native trees in the Union Hospital neighborhood, restoring tree canopy to a 20-square-block area that had lost many mature shade trees in recent years. On this crisp November morning, volunteers helped plant 100 large native Indiana hardwoods, giving the neighborhood a renewed canopy and a healthier future. A Community Ready to Pitch In Neighbors stepped onto their porches to watch crews of Rose-Hulman and Indiana State students, along with five hardworking teams from Gartland Foundry, fan out across the streets with shovels, tools, and bright yellow vests. Many of them had never planted a tree before; others were seasoned TREES Inc. team leaders who have been volunteering with us for more than 25 years. Together, they brought energy, laughter, and a shared sense of purpose to every yard and right-of-way. Leadership Behind the Scenes This large-scale neighborhood planting happened thanks to months of preparation—and many miles walked—by Bart Ping, TREES Inc.’s Vice President of Tree Planting. Bart personally surveyed every block, identified planting sites, coordinated with homeowners, and managed the complex logistics of selecting and ordering 100 trees. Supporting him in the field were two longtime TREES Inc. standouts: Gregg Carrick, our steadfast “tool man,” who ensured every team had the equipment they needed. Rhonda Beecroft, our volunteer-organization powerhouse, who helped assemble one of our most enthusiastic planting crews to date. We are also deeply grateful to the TREES Inc. Board of Directors, our Tree Planting Committee, and the many TREES members who stepped up to lead volunteer teams throughout the morning. Powered by Generous Support This planting was part of a larger initiative funded by a $75,000 grant from the Indiana DNR Urban Forestry Division, which made this and two additional Fall 2025 plantings possible. We were honored to have Jacob Roos, DNR’s Urban Forestry Executive Director—and a great friend of TREES Inc.—join us on site to lead a team. Local sponsors added their own touch of hospitality and support: Baesler’s, Square Donuts, and Rose Hill Landscaping helped fuel and equip volunteers throughout the day. A Stronger, Healthier Neighborhood By midday, the transformation was already visible. Blocks once marked by the loss of mature trees now had rows of sturdy young hardwoods—oaks, chestnuts, and other native species that will shade sidewalks, cool homes, and strengthen the neighborhood for decades to come. This planting was more than a volunteer event. It was a community rebuilding its canopy, neighbors reconnecting on their streets, and a celebration of TREES Inc.’s 35-year commitment to making Terre Haute greener—one block at a time.
Tree Planting 13th & Chestnut, Fall 2024
On November 2, 2024, 125+ volunteers gathered to plant 100 native Indiana hardwood trees in the street rows between 13th and 24th Streets and Chestnut to Liberty Streets. This planting showcased the power of volunteerism to keep Terre Haute green, beautiful, and sustainable. Volunteers from Rose-Hulman Institute of Technology, Indiana State University, and local businesses donated time and energy to support the initiative. Their work not only reduced the overall costs of planting but also allowed TREES Inc. to stretch donations and grants even further to benefit the community. The purchase of the trees was made possible through a $75,000 Inflation Reduction Act grant, which TREES Inc. received in early 2024 from the Indiana Department of Natural Resources. The grant’s primary objective is to help TREES Inc. plant at least 400 trees in 2024 and 2025. This effort is a response to the hundreds of trees lost in severe storms during 2023 and 2024, as well as an opportunity to address long-standing gaps in urban tree coverage. Many neighborhoods in Terre Haute, especially those with lower socioeconomic status, have been historically under-canopied. By working with the city’s urban forester, TREES Inc. is committed to planting trees in areas where they are most needed—creating shade, reducing urban heat, and improving air quality for the entire community.
Tree Planting near Sarah Scott, Spring 2024
In Spring 2024, the Sarah Scott Middle School neighborhood experienced a welcome transformation as TREES Inc. led a large-scale community effort to plant 100 native Indiana hardwood trees. Stretching along South 9th Street, this initiative brought long-lasting environmental benefits to an area in need of more tree coverage. The event drew over 150 volunteers, including local residents, students from Indiana State University and Rose-Hulman Institute of Technology, and employees from area businesses. This collaborative effort underscored the community’s shared commitment to making Terre Haute greener and more sustainable. Volunteers helped with every step of the process, from digging to planting to clean up. Funding for this project came from a $75,000 Inflation Reduction Act (IRA) grant, awarded to TREES Inc. by the Indiana Department of Natural Resources. This funding supports an ambitious goal of planting at least 400 native trees in Terre Haute during 2024 and 2025. Beyond replacing the many trees lost in recent severe storms, the project focuses on improving tree coverage in neighborhoods that have historically lacked adequate green infrastructure. "This planting wasn’t just about adding trees to the streetscape—it was about creating a healthier, more vibrant environment for everyone in the neighborhood," said Gregg Carrick, a TREES Inc. board member and the planting leader. "It’s exciting to know that these trees will provide shade, beauty, and cleaner air for generations to come."

Explore 101 Trees of Indiana Walking Trail

Take a walk through Indiana's native trees.
Created by TREES Inc. in 2005, the 101 Trees of Indiana Walking Trail follows a one-mile route around Memorial Stadium at 3300 Wabash Avenue.
Designed in the shape of the state of Indiana, the trail features native tree species selected from 101 Trees of Indiana, the field guide written by ecologist and TREES Inc. board member Dr. Marion Jackson.
TREES developed the trail with landscape design by Kevin Runion and support from the Terre Haute City Park Department and Indiana State University. The project was funded through a bequest from TREES member Guido Miescher. Today, TREES volunteers continue to help care for the trees along the trail.
In 2007, Wabash Valley Art Spaces added Tree, a monumental steel sculpture by artist Mark Wallis honoring the native trees and shrubs planted along the trail. Visitors can also find a map and information about the trees at the limestone marker near the sculpture.
Big Trees of Vigo County
Some trees are more than part of the landscape—they are living landmarks.

Big Tree Registry
TREES Inc.’s Big Tree Committee works to identify, measure and document the largest native trees in Vigo County. For many years, committee members have maintained the Vigo County Big Tree Registry, creating an important record of exceptional trees throughout our community.
The registry reflects a significant, ongoing volunteer commitment. Committee members visit nominated trees, identify species, take measurements and maintain records that help document Vigo County’s natural heritage and recognize trees worthy of appreciation and preservation.
Think you know a Big Tree?
If you have a large native tree that might be a contender, we’d like to hear from you. Our Big Tree Committee can help determine the species, take official measurements and compare it with other registered trees.
