Manipulation of climatic conditions

Ten Primary Garden Sites 

All Sites:• High quality weather station• Wisard‐based soil moisture and temperature• Phenocam• Site server • Water tank, pump, etc• Fence

Other Equipment:• Field gear, tools• On campus data servers• Plant physiology equipment• Ecosystem instrumentation• Molecular genetics laboratory

Additional site data:

• Phenocams

• Water chemistry

• Soil profiles

• Plant composition

• Ground dwelling beetle survey

Soil Profile Characterization by NRCS

Collaboration with other networks?

• Microclimate• Phenocams

Irrigation Control

Greenhouse test of soil moisture‐based actuation of irrigation valves

Projects at SEGA• At least 4 Macrosystems Biology grants using the sites and equipment

• Multi‐garden plantings to surveys to climate data use

• Trees to grasses to lizards

• NAU to Max Plank

Managed Relocation for Climate Change Mitigation

Hope to work with q new NSF‐funded effort led by PI Marissa Basket at UC Davis:

‘A framework for species conservation by managed relocation: quantifying risks, uncertainties, and alternatives.’

Whitham GroupQuantification of Performance of SourcesAcross Environments

Overlapping interests with managers:

• Invasive species• Native grass• Rare species• Ponderosa and fire• Food for wildlife, prairie dogs, golden eagles

• Climate‐vegetation relationships

Outreach and Education Opportunities

“The highlight of the whole trip was 

interacting with young dedicated scientists"

“I’ve never been this close to a research project before. I’m impressed by the rigor and 

the discipline that the scientists are bringing to this 

effort.” 

• Direct engagement with land managers

• Arboretum kiosks and educational materials

• Volunteer trips and high school involvement

• Online weather and phenocams

Research Partnerships with Tribal CollegesFunding has resulted in the establishment of a weather station and common garden with automated watering

Award No. 1126840
