This document discusses the benefits of replanting half of the land currently used for lawns with trees. It notes that replanting 20 million acres would create an area larger than several famous national parks combined. The document outlines many sustainability benefits of trees, including improved air quality, stormwater management, carbon storage, and habitat provision. It also lists benefits for human health and well-being such as stress reduction, lower energy costs, and higher property values. Maintaining biodiverse landscapes supports pollinator populations like chickadees that require caterpillars found on many different tree species.

5. Sustainability Benefits Cont.
 Provide habitat for people
 Lower energy costs through shading and warming
 Higher property values, lower vacancy rates, better
employee retention, lower crime rates
 Stress reduction, better health, reduced ADHD,
improved immune system functioning

7. Chickadees
 Need 6000 to 9000 caterpillars for 1 clutch
 @25 caterpillars per tree they need 250
trees
 @100 square feet per tree they need 1/3 of
an acre
 Per Dr. Douglas Tallemy author of Bringing Nature
Home

8. 7 Plant species in this picture

9. Large Amount of Plant Diversity

10. Predators

16. This is an ecological barrier where only pests live. It is
also lots of work to maintain because nature has been
expelled.

17. Insect and animal diversity depends on VERTICAL , horizontal and temporal
diversity.

18. HAZARD TREES

19. ROT

20. Included
Bark/
Bad
Branch
Union

21. Poor
Structure

22. Bad
Care

23. Trees fail under normal weather conditions
because of rot, bad branch unions, poor structure,
and bad care.
A certified arborists can find and correct these
conditions before the storm.
Trees, like cats, dogs and people, should be seen
by health care professional for preventive check
ups.
