Course Instruction:    ENVI 110: Intro to Environmental Sciences, ENVI 385: Structural Geology, ENVI 460: Conservation of Natural Resources, ENVI 415/515: Field Geography of the United States, ENVI 418/518: Soil Genesis and Classification, ENVI 465/565: Fundamentals of Tree Ring Research, EMVI 490/590: Biogeography, ENVI 497/597: Quaternary Paleoecology

Research Interests:  Biogeography, Dendrochronology

Research Profile: 

Dr. Speer is a dendrochronologist with experience in reconstructing environmental variables that affect tree growth, such as insect outbreaks, fire, masting, and climate.  He is excited about the many uses and more widespread applications of dendrochronology.  He is presently developing tree-ring chronologies in the tropics where previously researchers had thought that annual rings did not form.  He has developed the first insect outbreak reconstructions on pandora moth, a frequent defoliator of western pine forests and he has developed new methods that enable dendrochronologists to use treerings to reconstruct past fruiting in oak trees.  He has received 5 NSF grants and many other federal grants to fund his work
