Impacts From Climate Change • Lack of diversity = more susceptibility to pressures that affect them and greater impact to the overall urban forest • Climate Change • Increased temperatures • Changes in rainfall • Pests and diseases
• Disease pressure
• Laurel Wilt (Raffaelea lauricola/Xyleborus glabratus) • Lethal Bronzing (Phytoplasma palmae) • Oak wilt (Ceratocystis fagacearum) is a potential future threat in Florida

Opportunities to Address Climate Change • Opportunities to explore and promote native diversity • 116 species of native trees in South Florida/63 Collier County • 165 species of native shrubs/98 Collier County • Natives for your Neighborhood (Institute for Regional Conservation)
• Improve quality of life • Greatest potential for impact on quality of life is in areas of lowest tree equity As practitioners, we all play different roles but can make a difference
Opportunities to Address Climate Change • Education and Outreach • Public education • Professional education
• Landscape Architects • Municipal Employees • Landscape Maintenance Companies
• Example Landscapes and Plants • Naples Botanical Garden – Parking lot • Naples Zoo • Edison and Ford Winter Estates • Sanibel-Captiva Conservation Fdn Native Landscapes & Garden Center • Landscape Architects
