Arboretum Phenology and Climate Response (3.44158)
Date: 2011 – 2016Creator: Fahey, Bob
Type: Dataset
Description:Phenology monitoring was conducted by Fahey, Carrier, and multiple volunteers in the spring and fall of each year from 2011 through 2016. The dataset includes ~685 individuals from the Juglandaceae, Midwest, Northern Illinois, Ozark, Quercus, Tilia, and Ulmaceae collections at The Morton Arboretum. Traits monitored include: fruiting, bud condition, leaf size, flower condition, and leaf fall, and leaf color. Protocols can be found in T://Fahey/Current Projects/ Arboretum Phenology and Climate Response/Protocols.
Coastal Pines Tree Cores (3.44159)
Date: 2011 – 2012Creator: Fahey, Bob
Type: Dataset
Description:The dataset includes tree cores from approximately 500 trees from eight sites around Lakes Michigan and Superior. Annual growth increments were measured to 0.001 mm using a Velmex stage micrometer and Metronics Quick-Check 4100.
ILDNR/INAI Tree Cores (3.44162)
Date: 2012Creator: Fahey, Bob
Type: Dataset
Description:The dataset consists of nearly 200 tree cores from 11 different sites in northern and southern Illinois. Ring-widths were measured under magnification of a binocular microscope to the nearest 0.001 mm with a Velmex Unislide slide-stage micrometer interfaced with a computer and MeasureJ2X program.
Project conducted in 2012. Cores were collected in 1976 and 2008-2011.
Timing of stem growth for Oaks from around the world (3.44168)
Date: 2010 – 2018Creator: Rollinson, Christine R.
Type: Dataset
Description:Dendrometer band installation was performed by Rollinson and Duckett, and monitoring will be performed by these two along with volunteers. Installation protocols can be found here. Monitoring will be conducted once per week, year-round on 32 oak trees in The Morton Arboretum Oak Collection. Diameter at breast height (DBH) and circumference are measured at the time of dendrometer installation, and the weekly measurements will show the increase in circumference over time, which may be converted to diameter if necessary. Trees were selected that were native to the Chicago area of Illinois, were accessioned before the year 2000 so they would be large enough to install dendrometer bands, and had at least three individuals fitting the first two criteria. The English oak, Quercus robur, was also included.
