Conserve School is a semester school for environmentally and outdoor minded high school students located in Land O' Lakes, Vilas County, Wisconsin, United States. For seventeen weeks students pursue a program of environmental studies and outdoor activities that is designed to deepen their love of nature, reinforce their commitment to conservation, and equip them to take meaningful action as environmental stewards.
The program interweaves college-preparatory academics with:
- the study of environmental history, nature literature, and the science of conservation,
- environmental service work,
- exploration of careers related to conservation,
- training in teamwork and leadership, and
- engagement with the outdoors.
The Conserve School academic program is made up of two types of courses, Core Courses and Electives.
All students take the five core courses:
- Environmental Science: Applied Ecology and Sustainable Systems
- English: Wilderness Voices, American Literature and the Land
- History: The History of Wilderness Exploration: the Northwoods and Beyond
- Physical Education: Pack, Pedal, and Paddle: Outdoor Skills and Activities
- Stewardship for Life: An investigation of colleges and careers
Students select their electives based on their individual needs. Math and Spanish electives focus on keeping students up-to-date in these sequential and skill-based subjects. Art electives allow students to explore their creativity. The Advanced Placement Environmental Science elective combines with the required environmental science class to give students a year's equivalent of AP Environmental Science.

Conserve School's 1,200-acre (4.9 km2) campus was named Lowenwood by Conserve School's founder, James Lowenstine. The campus has access to eight lakes (of which four are completely enclosed by school property). The campus is adjacent to the Sylvania Wilderness and Sylvania Recreation Area and its additional 18,327 acres (74.17 km2) of forests, lakes, and streams.
The Lowenstine Academic Building (or LAB) is the main campus building with a variety of classrooms, art & music spaces, a theater, dining room, library, and expansive indoor open area called the Gathering Space. The Lowenwood Recreation Center (or LRC) is the hub for athletic and outdoor activities with its gymnasium, fitness center, outdoor equipment room, locker rooms, and welcoming lounge. Students can check out a variety of equipment from the LRC to aid in their outdoor pursuits including bikes, boats, skis, snowshoes, and ice skates. Elaine House is home for the girls on campus and the boys live in Donahue House.
There are roughly 22 miles (35 km) of trails on Conserve School's grounds, which students use for hiking, biking, snowshoeing, and skiing.

With the passing of James Lowenstine in 1996, the building of his dream, a school to inspire conservation minded environmental stewards, began. Following the directions Mr. Lowenstine left in the Conserve School Trust the Conserve School Board of Trustees began the initial planning for Conserve School. Mr. Lowenstine directed the Trustees to create a school with a curriculum that would include: instruction in reading, writing, arithmetic, and nature study. The nature study was to include a focus on the ecology of unspoiled forest and lake areas such as Conserve School’s Lowenwood campus. In addition the school should include instruction in outdoor sports including skiing, use of snowshoes, archery, ice skating, target practice, swimming, fishing, boating, camping, sledding, methods of survival in unexplored areas, and other outdoor activities.
From the fall of 2002 until the spring of 2010 Conserve School operated as a four-year college preparatory school. Due to financial concerns, the school switched to its current semester school model in the fall of 2010. The decision to transition the school was legally challenged by a group of concerned parents, alumni, and community members, as well as by the Culver Educational Foundation.
On August 21, 2010 the first semester school semester began with 48 students from 12 different states.
On November 14, 2005, a lawsuit was filed against Conserve School by the Culver Educational Foundation, parent of Culver Academies in northern Indiana. The suit alleged a breach of fiduciary duties on the part of Conserve School's trustees, claiming the construction and continued operation of Conserve School was financially unsustainable. Culver stood to inherit nearly all of the trust assets should the operation of Conserve School be declared financially impractical. On May 25, 2007, at the request of Culver, the lawsuit was dismissed with prejudice, with all parties to bear their own costs and attorney's fees.
In response to the Conserve School Trustee's decision announced in January 2009 to transition to a semester school, a group of parents and alumni filed a lawsuit to preserve the four-year program  The case was filed in Vilas County Circuit Court on February 20, 2009. On April 7 the Culver Educational Foundation joined the lawsuit against Conserve School. On April 14, Wisconsin Attorney General J.B. Van Hollen asked the Vilas County Circuit Court for permission to intervene in the lawsuit. On June 8 the Vilas County Circuit Court upheld the Conserve School Trustees’ right to transition to a semester school and denied the Wisconsin Attorney General's request to intervene. The Culver Educational Foundation appealed the ruling to the Wisconsin Court of Appeals. On November 16, 2010 the Wisconsin Court of Appeals for District III affirmed the ruling by the Vilas County Circuit Court. The Wisconsin Court of Appeals decision concludes with the statement, “Although the trustees’ new program is a significant departure from the way the school previously operated, it does not reflect a finding of legal impossibility or impracticality. To the contrary, it reflects the trustees’ desire to operate the school in a manner best suited to current economic realities within the boundaries of the trust instrument.”
