Just What is an ACE Crew?

On a warm July day, the Land Trust welcomed an American Conservation Experience (ACE) crew to our Linda Falls Preserve, bringing fresh energy and dedicated hands to the ongoing restoration work.

ACE is a national nonprofit that provides young people with hands-on conservation experience, supporting projects across the country—from wildlife surveys and trail maintenance to creekside restoration. With support from grants and generous donors, the Land Trust partners with ACE crews to advance critical stewardship work across our permanent preserves.

At our Linda Falls Preserve, that work is especially urgent. Invasive plant removal remains a top priority, and this crew spent their days tackling aggressive species that threaten the health and resilience of the landscape.

During a midday break, the crew gathered in the cool shade along Conn Creek, taking a moment to rest beneath a dense canopy of trees. It was there, surrounded by the very landscape they were helping to restore, that Land Trust staff had the chance to learn more about who they are and what brought them to this work.

Matthew Larsen, a recent biology graduate from St. Petersburg University in Florida, joined ACE to gain hands-on field experience. Drawn to California’s unique landscapes—where mountains and ocean are never far apart—he’s found meaningful work in restoration efforts like those at Linda Falls.

Larsen, of Tampa, Florida, recently graduated as a biology major from St. Petersburg University. He started working with ACE in May and joined to gain more hands-on field experience. He likes California, with the mountains and ocean close by, and even surfs on his off days. Working at Linda Falls Preserve is a good fit for him precisely because of the restoration effort.

“I love doing invasive (plant removal) work,” said Larsen. “That’s the basis of habitat restoration.”

Elizabeth Riesenberg of Omaha, Nebraska started working for ACE five months ago after having graduated with a biology degree. Working in previous locations like Pinnacles National Park and on locally protected land in Irvine, California have been highlights not only for their scenic views, but also for what she’s encountered. The invasive work in Irvine, for example, consisted of pulling artichoke thistle and mustard of a size she could hardly believe.

“The mustard was huge,” remarked Riesenberg.

Benjamin Strickland of China Grove, North Carolina rests during his lunch break.

Benjamin Strickland of China Grove, North Carolina graduated in March and got involved with ACE right away. Strickland wanted the hands-on experience as well, but also wanted to meet new people.

“Plus, I like being outside,” said Strickland. “I definitely like being outside more than inside.”

Leading the crew was Jenny Diamond, who joined ACE in 2015 and now serves as crew chief. Her role blends fieldwork with mentorship—ensuring the crew stays safe, supported, and continuously learning.

“I like the role of passing on my knowledge to new members as that is part of what makes ACE great,” said Diamond. “It’s a great introduction to the hard work involved in the field of conservation.”

As the crew packed up and returned to work, it was clear their impact extended far beyond the acres they were restoring. These young conservationists are part of a larger movement—one that’s restoring landscapes, building skills, and shaping the future of stewardship across the country.
