1. Where are other mini-forests located?

Mini-forests have been planted in many countries, from France and the Netherlands in Europe, to India
and Japan. Mini-forests have also been planted in several cities in the U.S. The first mini-forest in New
England was planted at Danehy Park in Cambridge, Massachusetts in 2021. Cambridge planted its
second mini-forest in 2022.

2. What is involved in planting a mini-forest?

All of the vegetation planted in a mini-forest must be native to the region and should be compatible
with conditions unique to the planting site. Generally, between 30 and 50 different species are planted.
Most of the species are canopy trees, understory trees, and shrubs.
The trees and shrubs are planted as seedlings. Before planting, the soil is de-compacted and enriched
with compost to ensure that seedlings have access to ample food and nutrients. Approximately three
seedlings are planted per square yard. After planting, the soil is topped with mulch to encourage
moisture retention and deter weeds. Fencing may be needed to protect the mini-forest from animals
during the first three years.

3. Why is a mini-forest cost-effective?

The cost of planting a mini-forest depends on its size and the amount of preparatory work needed.
Expenses include plants; labor, supplies, and equipment associated with preparing the soil; and
fencing to protect the mini-forest during the first three years. Planting seedlings is less expensive than
planting 6΄-8΄ trees. Using volunteers to plant a mini-forest helps the town save in labor costs. Once a
mini-forest is planted, the costs are minimal. Periodic weeding and watering are needed only in the
first three years. After three years, the forest maintains itself.

4. How can I get involved?

Brookline residents will be invited to share their thoughts in public hearings about proposed locations for a mini-forest. Additionally, all community members will be encouraged to participate in planting
the mini-forest and helping with weeding and watering in the first three years. Most importantly, it is
hoped that Brookline residents will enjoy the forest by watching it grow and experiencing the shade
and biodiversity it brings to the surrounding area!
