Impacts of Conservation Land on Property Taxes and Municipal Budgets in Maine
How does land conservation impact mill rates and town budgets in Maine?
This project was co-created by the University of Maine School of Forest Resources and the Municipal Budgets and Conservation Working Group, a diverse group of conservation professionals, municipal leadership, selectboard members, town managers, and others who want to understand the impacts of conservation on their communities.
Using a mixed methods approach, we measured the impact of conservation on property tax rates (referred to in this study as the “mill rate”) and municipal budgets in Maine. We ran analysis on available data, controlling for confounding variables, conducted a public perceptions survey, and engaged with 20 professionals through interviews. From our findings, we provide recommendations for municipal and conservation decision makers.

Overview and Background
Conserved land in Maine has increased significantly over the last thirty years. Conservation in Maine has increased from 5% of the state’s land area in the 1980s to more than 20% today including in the Unincorporated Townships.
When land is conserved in Maine, it is often granted tax exempt status or taxed at the Current Use rate which theoretically reduces the tax base of the town. Using simple accounting, the town would need to cover the budget deficit by increasing the mill rate. However, the impacts of conservation on communities are complicated in the long run.
Conservation can provide ecosystem services and amenity effects on surrounding properties, attract tourism, and limit development, all of which could impact a town budget. This was demonstrated through a study commissioned by Downeast Conservation Network to comprehensively assess the economic contributions of conserved lands.
“Valuing the Economic Benefits of Conserved Land in Downeast Maine“
The report includes economic valuation of ecosystem services provided by regional conserved lands: benefit transfer valuation of non-market ecosystem services, direct valuation of market-based ecosystem services, and calculations of visitor spending effects and employment contributions to the local economy. While this study helped fill important data needs, it did not explore the larger suite of impacts, including but not limited to land conservation, on municipal budgets.
Municipalities in Maine face many challenges in maintaining balanced budgets. Among them, a decrease in state revenue sharing and funding for general purpose aid to education, impacts from tree growth and open space tax laws, property tax revenue loss from Federal, state, private or non-profit conservation lands, and other lands in some form of non-profit status. The loss of revenue and increase in costs have meant rising property taxes and the increase in property taxes has a disproportionate impact on the poor and elderly.
Municipal Budgets and Conservation Working Group Quick Facts:
- Established in 2019 lead by Washington County Council of Governments and Downeast Conservation Network.
- A collaborative group of conservation professionals, researchers, municipal leadership, selectboard members, and town managers and others who have joined together to collect and analyze data on the many factors impacting municipal budgets in the Downeast region and across the state of Maine.
- Focused on gathering and sharing information based on data, rather than perceptions.
- Created to develop a transparent and collaborative process to provide feedback to the research study
The Municipal Budget and Conservation Working Group is based in the Downeast region but is focused on addressing the impacts of state-wide policies on rural municipalities across the state of Maine.
