L. Barnett Phenology What is phenology? Nature s calendar The science of the seasons Blooms and buds Hibernation, migration, emergence Easy to observe Who observes phenology? Scientists Gardeners Agriculturists Land managers Youth Famous historical figures it is the study of recurring plant and animal life-cycle stages, or phenophases, and their relationship to environmental conditions. C. Enquist
Phenology A big picture concept That ties it all together.
Thoreau Jefferson Phenology History and Phenology Research, spring timing and range Record keeping Journals, herbarium Crowd-sourced data, lilacs Spring Index Results 43 species at Walden Pond bloom 7 days earlier than 150 years ago 1/3 of species the Leopolds recorded are arriving 2-3 weeks earlier SPECIES AND ECOSYSTEMS ARE INFLUENCED BY GLOBAL ENVIRONMENTAL CHANGE

A healthy watershed is one in which natural land cover supports dynamic hydrologic and geomorphic processes within their natural range of variation; habitat of sufficient size and connectivity supports native aquatic and riparian species; and water quality supports healthy biological communities.

Phenology Onset of summer flowering in a Sky Island is driven by monsoon moisture Theresa M. Crimmins, Michael A. Crimmins, and C. David Bertelsen New Phytologist (2011) 191: 468 479. Low elevation - monsoon precipitation More favorable conditions result in earlier flowering date The wetter the year, the earlier the flowers appear Relationship between July precip and first flowering date for 6 species recorded along a route on Mt. Kimball, Santa Catalina Mountains, Tucson, AZ. 1984-2009
Phenological patterns are important, economically and biologically and sensitive to climate and sensitive to climate change. Phenology is perhaps the simplest process in which to track changes in the ecology of species in response to climate change. (IPCC 2007) Because of their close connection with climate, the timing of phenological events can be accurate indicators of climate change. (EPA 2010)

Phenology 1. Plant and animal development rely upon internal, environmental and climatic cues 2. Changes in climate affect the food chain 3. Plants and animals can only reproduce under optimum conditions 4. Changing conditions alters species tolerance RESPONSE: Shifting phenology (life-cycles) Shifting range boundaries, new biome? Changing morphology Extirpation or Extinction http://www.ipcc.ch/
Tracking Phenology Overview Phenology and Climate Nature s Notebook and the USA National Phenology Network Local Applications
USA National Phenology Network Primary goal To encourage observation of phenological events and understand how plants, animals and landscapes respond to environmental variation and climate change. A NATIONAL NETWORK OF INTEGRATED PHENOLOGICAL OBSERVATIONS ACROSS SPACE AND TIME. Mission Make phenology data, models and related information available to scientists, resource managers and the public. Encourage people of all ages and backgrounds to observe and record phenology.
USA National Phenology Network What Is Citizen Science? Engages volunteers Expands ability of scientists Teaches scientific methods Public and professional scientists Research teams Educate and generate data Meet science & research goals Eliminates gloom and doom Citizen Science Info www.birds.cornell.edu/citsci/about www.citsci.org www.scistarter.org

Tracking Phenology Overview Phenology and Climate Nature s Notebook and the USA National Phenology Network Local Applications
Local Applications In Our Gardens By observing plant and animal species here, a local dataset can be compiled and analyzed to determine the impact of increasing drought and unpredictable climate conditions on the life cycles of these systems. Bloom times on irrigated plants vs. non-irrigated How are temperature changes affecting bloom time in native plants? What are the affects of the cold snap on bloom times? Do all ocotillo put on leaves after the seasonal rains? When do the inflorescences appear? When do pollinators visit the pollinator garden? Is there a relationship to blooming host plants? Are patterns in pollinator behavior changing? And Is precipitation impacting water needs and health of urban landscapes?
Local Applications What is a Phenology Trail? A phenology trail is a network of Nature s Notebook observation sites. Each site has at least two plant and/or animal individuals tagged for data collection.
Local Applications Species being monitored Jojoba Velvet mesquite Yellow paloverde Blue paloverde Ocotillo Creosote Florida hopbush Saguaro Penstemon (parryi) Texas Ranger Desert Ironwood Important to know natives
Local Applications Tucson Phenology Trail Currently 7 locations Biosphere 2 UA Campus Sam Hughes Neighborhood Pima Extension Offices (2) Santa Rita Experimental Range Tucson Audubon Mason Center Tumamoc Hill Madera Canyon Total of 75 Miles, start to finish 3-10 species tagged at each
Phenology, in short, is a horizontal science which transects all ordinary biological professions. Whoever sees the land as a whole is likely to have an interest in it. A. Leopold
