Arnold Arboretum

Curatorial Procedures

Records

Records for each accession in the collection are housed in BG-BASE, a PC-based database.  Link to Plant Inventory
Intensely curated, BG-BASE stores plant information including:

Data may include performance observations, unique ornamental characteristics, growth and survival rates, hardiness potential, specific propagation techniques, a botanical description, and taxonomic verifications. Additional notations may document storm damage, susceptibility to insects or diseases, or experimental data. Observations on plant collections are ongoing and formal assessment activities are documented in the Arboretum’s Plant Inventory Operations Manual.

Identification, Taxonomy, and Nomenclature

The living collections of the Arnold Arboretum are curated to ensure that plants are correctly identified, that contemporary taxonomic or classification schemeAccession Books and Cardss are being considered, and lastly, that accurate nomenclature is being applied. A number of activities assist curatorial staff in accomplishing these goals: voucher herbarium specimens are prepared and deposited in the Cultivated Herbarium, the identity and correct name of accessions are researched, and the scientific literature is regularly reviewed. Also, because the collections are a resource for scientists around the world, much ‘taxonomic progress’ (i.e., changes in identification, taxonomy and/or names) occurs as a result of their research.

Labels

Plants in the collections retain anodized aluminum records labels that provide accession number, letter qualifier (denoting individuals of an accession), family, botanical name, means of propagation, lineage number, provenance (source/collection data), common name, and Arboretum grounds location. Each records label is embossed in-house using a DataCard 295 Card Personalization System.

A Typical Records Label

parts of a plant label

In addition to records labels, two types of display labels aid in interpreting Arboretum collections.  The first and most ubiquitous are trunk labels that provide common and scientific names, nativity, and the botanical family to which the genus belongs. New trunk labels bear the afore mentioned information along with an accession number and year of accession.  The second are stake labels which are positioned in front of plants in the Bradley Rosaceous Collection, Explorers Garden, Leventritt Shrub and Vine Garden, and Hunnewell Building areas. Stake labels provide nativity, common, and scientific names.

A thorough disscusion of labeling, including label standards and source guides, can be found in our Plant Inventory Operations Manual, Appendix I.

Mappinggrid map

The Arboretum utilizes a suite of ESRI Desktop and Mobile GIS software applications to manage, analyze, query, capture, manipulate, and display geographic information.  Decimeter accurate field mapping of landscape features (e.g., plants, benches, signage) is accomplished using a Trimble Nomad handheld computer attached to a Trimble GPS Pathfinder ProXRT receiver, GLONASS option.  Search Arnoldia to read more about historic cartographic efforts at the Arnold Arboretum.

Locations within the Arboertum are defined by a grid overlaid onto a base map that divides the property into 70 individual maps, each 400 feet by 600 feet. Each map is further divided into 4 quadrants (200 feet by 300 feet) labeled NW, NE, SW, SE. Beds and structures within named garden areas (e.g., Explorers Garden) are given their own location designations. Taken together, these locations aid reserachers and visitors as they wayfind to plants within the collections. Plant locations are made available through our searchable plant inventory, published maps, and records labels.
