3nd Annual Trees Matter Summit

Wednesday - Oct. 5, 9:30am - 1:30pm


Join us for the Thrid Annual Tree Summit. Space is limited. Register now.

Teams of middle and high school students and teachers are invited to attend this free educational event.


The social, economic and environmental benefits of urban & community forests are at the center of “Why Trees Matter” for Ohio’s communities and citizens. Street tree commissions, mayors, community development and economic development managers, utility companies, nurserymen and landscapers, and homeowners all have a vested interest in the growth and health of trees in our urban and suburban areas.


Another part of the population that should be aware of and involved in this effort are teachers and students in our school systems. The Holden Trees Matter Summit is designed to engage middle and high school students and teachers in a variety of efforts to increase awareness of the value of trees on their school grounds and in their communities.


Schools are invited to send teams to the Tree Summit for a one day educational and informational summit. They will hear from experts in the field of forestry, environmental planning, and others to learn about ways they can take this information back to their schools to enhance the presence and importance of trees on their school grounds. They will also learn about science-based educational resources to document and demonstrate the value of trees.


After the Summit, students will be asked to develop a plan for their school that will encourage and promote the value of trees. It will most likely include doing an inventory as well as working with school stakeholders to increase the green canopy on their school site. A certification with various levels of achievement is being developed. Schools can obtain assistance from Holden as well as tools for doing an inventory and working through the steps of the certification.


Schools are encouraged to come back in subsequent years to gain more knowledge and to present their work to other schools. Every year the curriculum will change so that repeat attendees are always learning new information to assist in their work.

Tree Summit Teacher Training and Information Session

Monday, Sept. 26, 4 - 7pm


Come see what the Tree Summit is all about and how it would fit into your curriculum. Learn how i-Tree and other data systems can be used in the classroom to calculate tree benefits and map school grounds. Teachers do not have to be signed up for the Tree Summit to attend. This is the perfect time to get your questions answered about this new middle/high school program as well as learn some tree science applications for your classroom.


Teachers will also gain access to a new curriculum that utilizes I-tree to teach about ecosystems and sustainablity. Teachers who are signed up for the Summit are encouraged to attend to learn more about the applications for their classroom. Others are welcome to come and learn more about the importance of trees to school grounds.


Cost: Free, but pre-registration is required. Dinner will be provided.


Direct questions or registration to Sharon Graper, 440-602-3843.
