Who We Are

American Forest Kindergarten Association

We are a national organization bringing together educators, parents, policy-makers, and other stakeholders passionate about the forest kindergarten model.

As the growing body of compelling scientific evidence demonstrates what we have all long held to be true – that introducing children to the natural world at an early age has a profoundly positive impact on their mental, physical, and social well-being – the need for advocacy of nationwide standards in nature immersion becomes increasingly necessary.

The American Forest Kindergarten Association (AFKA) has the goal to unite early childhood educators, parents, policy-makers, and other stakeholders in the interest of encouraging children to become attuned with their surrounding natural environment and the American landscape.

AFKA is an independent voice in the national discussion on outdoor education, leveraging the weight of the association and that of our individual members to inform the debate on national priorities for our children’s future.

AFKA seeks to be a valued partner to institutions, associations, individuals, and other entities that share the common goal of encouraging policies designed to establish and facilitate the establishment of consistent standards and programs for physical exposure to the natural world as an essential component of early childhood education on a national level.

To be considered as following the American Forest Kindergarten Model, these criteria should be in place:

1. A minimum of 1-3 hours of unstructured free play in nature.

2. Flow Learning (aka Interest-led or Child-led) is implemented. Flow learning leads to emergent curriculum, the lessons that emerge when children are free explorers in nature.

3. Inquiry Based teaching is used. Teachers are there as guides (reflecting back awe and wonder in nature) and not the center of attention. Activities can be offered, but are not required.

4. Documentation of learning is collected primarily for teachers to reflect what children are responding to; i.e. social emotional growth, as well as what strategies are working or need work. It can also be shared with parents as a way to build family communication in addition to helping parents feel more comfortable in their own interacting in nature with their children. In today’s data driven culture, the collection of documentation can provide anecdotal evidence as well as credibility for the school.

"Believe one who knows: you will find something greater in woods than in books. Trees and stones will teach you that which you can never learn from masters."
- Saint Bernard de Clairvaux

Her award winning film “NaturePlay-Take Childhood Back” was a result of enrolling her daughter in a forest kindergarten in Denmark, the country where the concept of forest school began.

Aimie is a champion of a child’s right to a “Good Childhood”, free of abuse, full of joy and play, while being supported by developmentally appropriate pract​ic​e in education and policy making. She hopes to inspire a global culture and education shift towards improvement in key outcomes for children. With a specialty in the Nordic Model she currently leads N.O.M.E education study tours in Scandinavia, is a frequent university guest speaker​, and continues to produce films for a better world. Her background before film making was as a US National Park Ranger with a focus on backcountry rescue at Grand Canyon National Park and environmental education at Everglades National Park with nationwide assignments as a pioneering female in Wildland Firefighting, Wilderness Medicine, Federal Incident Management Teams-Medical Unit Leader,and Biological Research USFWS at NASA Kennedy Space Center.​
