IMLS grant funds geo-referenced, integrated database
In July 2012 the Institute of Museum and Library Services awarded a Museums for America grant to UW Botanic Gardens to integrate an all-inclusive database, using Geographic Information Systems (GIS) technology. The multi-part project will ultimately allow for one point of access to herbarium, horticultural and curitorial records linked to an Arc-GIS generated map, searchable from any web-connected devise. The database will be used to advance environmental research, improve Arboretum management and expand interpretation of the woody plant collections.

And, there’s the “old” as in a staff milestone reached in age by none other than Riz Reyes, Soest Gardener. Sure, compared to most of our seasoned horticulture staff, he’s still just a sapling in the woods at 30, but ever so slowly, he’s beginning to put down roots and develop heartwood, true elements of perennial long-life.
