The University of Victoria Tree-Ring Laboratory (UVTRL) is housed in the Department of Geography at the University of Victoria.

The UVTRL provides a focus for the research activities of undergraduate and graduate students who are using insights developed from measurements of tree rings to describe the Holocene environmental character of the British Columbia Coast Mountains. Research is focused on dendrochronology, dendroarchaeology, dendroclimatology, dendroentomology, dendrogeomorphology and dendroglaciology.

    Laboratory Instrumentation

    The UVTRL is equipped with two WinDendro digital tree ring measurement systems and two Velmex tree ring measurement systems equipped with trinocular boom-mounted microscopes and CCD video displays. The UVTRL also houses a filmless ITRAX X-ray densitometer. Intended to support climate change studies through tree ring measurement of earlywood/latewood parameters, UVTRL densitometric studies are supported by a Walesch Electronic Dendrocut twin-bladed saw.

    UVTRL researchers are also EvaluTree partners, and have ready access to a globally unique grouping of infrastructure for analyzing and researching wood fibre properties. Included within this instrumentation is the only North American-based SilviScan instrument that uses a range of analytical technologies, including optical microscopy, x-ray diffractometry, x-ray densitometry, image analysis, and applied for the rapid analysis of wood samples.

  • UVTRL Field Research:

    Summer 2013: Researchers from the UVTRL completed fieldwork in the Mt. Waddington area at Franklin Glacier in the central Coast Mountains, at Knipple and Salmon glaciers in the Boundary Ranges of the northern Coast Mountains, and in the vicinity of Perkins Peak along the western edge of the Chilcotin Plateau. See our 2013 photo album from our July travels.

    Summer 2012: Researchers from the UVTRL completed fieldwork in the Mt. Waddington area at Franklin Glacier, at Queen Bess Glacier at the northern end of the Homathko Icefield, and at numerous sites in the Boundary Ranges from Terrace to Cassiar. See our 2012 photo album from our July travels.
