Viewing City Trees as Infrastructure: Communicating Ecosystem Benefits of the City and County of Honolulu’s Tree Inventory
LINDSEY WATANABE with MARIA WELVAERT & NAVIN TAGORE
Trees growing in urban environments provide numerous benefits to our communities, enhancing quality of life socially, environmentally and economically. Urban forestry is an essential asset to the City as infrastructure. By utilizing data from the Division or Urban Forestry’s Tree Inventory and Urban Tree Canopy Assessment we can get a better look at canopy coverage in urban spaces, identify known climate risks, and prioritize climate mitigation efforts with tree preservation and plantings.
SESSION 2 - 10:30 AM
Plant Less Trees
STEVE NIMZ
Size does matter in the world of urban trees. Trends have been to plant more small trees to replace large trees, but this is not an equal trade. Large, mature trees provide significantly more ecological and infrastructural benefits than smaller trees, including shade, urban cooling, stormwater management, and carbon storage. Tree planting efforts should shift the focus from quantity to quality, with emphasis on planting fewer large canopy trees to increase urban canopy cover.
SESSION 3 - 12:30 PM

Lei Plants in the Landscape
ALBERTO RICORDI
The tradition of giving and wearing lei symbolizes love and the spirit of aloha. As local flower growers decline and weather events reduce flower production, demand for locally grown lei plants continues to rise. With more lei plants used in build landscapes, proper care is increasingly important. This session highlights common lei plants used in landscaping and shares practical management, pest management, and maintenance techniques.
