Grand Challenge: Urban plants and ecosystem services

Enhancing food access and ecosystem services for equitable human and ecosystem health in high population areas

Identify how the built environment can contribute to a more sustainable and climate resilient world for urban populations across the economic spectrum
  • Develop and sustain green spaces in urban/peri-urban areas encompassing parks, community gardens, botanic gardens, turf, and green infrastructure
  • Improve strategies to select and maintain trees and other plants in urban environments
  • Monitor and promote soil health and remediation in developed landscapes
  • Enhance and promote the ecosystem services of built environments such as erosion and flood control, habitat for wildlife, and carbon storage
  • Promote the human wellness benefits of greenspaces
Foster sustainable urban agriculture practices that contribute to human health, economic viability, and resilient, equitable food systems
  • Facilitate the vitality of diverse and effective urban agriculture practices in soil, raised beds, rooftop gardens, and protected environments
  • Improve the sustainability and economic viability of production of high nutrient density food in protected and controlled environments such as high tunnels, greenhouses, rooftop, and vertical farms (Controlled Environment Agriculture)

Grand Challenge Research: Urban plants and ecosystem services

Tree mapping for cooler cities

Researchers have developed the first citywide, “wall-to-wall” map of New York City’s trees, identifying 1.8 million individual trees, including 1.4 million that had never been surveyed because they are located on private property, in natural areas, or other previously unmapped locations. 
 
By combining satellite imagery, lidar data, and ground-based observations, the team created a tool that can help cities make smarter decisions about where and what to plant to maximize cooling, improve air quality, reduce flooding, and address other urban environmental challenges. The approach can be scaled to hundreds of cities across the United States and potentially worldwide. 
 
A key contributor is Daniel Katz, assistant professor in Cornell’s School of Integrative Plant Science, whose research focuses on using data and remote sensing to better understand and manage urban forests. The project supports efforts to reduce heat-related health risks as cities face increasingly severe heat waves.

Championship turf, sustainable science

At the 2025 Ryder Cup at Bethpage Black, golfers competed on a course shaped by decades of Cornell research aimed at reducing environmental impacts while maintaining championship-quality playing conditions. 

Through a 25-year partnership with New York State Parks, Cornell researchers helped cut pesticide and fertilizer use, improve soil health and adopt science-based management practices now used on public golf courses across the state. Beyond Bethpage, the turfgrass program develops data-driven tools for irrigation, nutrient management and turf performance, while testing emerging technologies such as remote sensing to improve efficiency and sustainability. 

The work is led by Frank Rossi, associate professor of horticulture and turfgrass extension specialist in Cornell’s School of Integrative Plant Science, whose research translates directly into practical solutions for golf courses, athletic fields and other managed landscapes.

Urban Plant Ecology Lab explores biodiversity, human-nature interactions

Under the leadership of Aaron Sexton, our new Urban Plant Ecology Lab seeks to understand how urban ecosystem management influences biodiversity patterns and processes. Research focuses around urban plant and animal communities how they influence human-nature interactions. Research topics include how urban community gardens affect pollinators and natural enemies of pests, restoration of plant-pollinator communites, urban heat island effects on timing of flowering, and impacts of urban wildfires. Techniques range from ecological field work, large-scale data synthesis, and socioecological research including collaborations around New York State, New York City and in Europe.

Plants, pollen and people - assessing ecological services & 'disservices'

The Katz Lab focuses on modeling airborne pollen concentrations, quantifying the cooling effects of urban trees, and applying ecological concepts to more effectively use remote sensing for urban tree identification. "My goal is to generate the ecological knowledge necessary to address plant-related public health problems," said Dan Katz, assistant professor in the Soil and Crop Sciences Section of the School of Integrative Plant Science. "To do so, I measure ecological processes using field studies, scale from individual plants to landscapes with remote sensing, and combine these into models related to ecosystem services and disservices."

Controlled Environment Agriculture (CEA) fuels urban, vertical farms

CEA is an advanced and intensive form of hydroponically-based agriculture using sophisticated lighting and environmental control systems that help make indoor farming more efficient and sustainable. See also: Greenhouse Lighting and Systems Engineering (GLASE) – a public-private partnership led by Cornell and Rensselaer Polytechnic Institute to integrate advanced energy-efficient LED lighting with improved environmental controls for more efficient and sustainable greenhouse production.

Reducing climate risk from urban wildfires

In 2024, several large wildfires scorched dozens of wooded acres in several boroughs of New York City – a region previously thought to be relatively safe from fire risk. Because such fires are so rare, these sites offer a unique and exciting opportunity to study changes in plant communities caused by fire and develop ecological management strategies to prevent even more dangerous fires in the future by reducing the fire fuel-load. In 2025, our Urban Plant Ecology Lab began surveying two of the largest NYC wildfire sites – in Prospect Park in Brooklyn & Inwood Hill Park in Manhattan, and is already seeing some interesting results!
