Description: The Plant Center point feature class is used to store the center point locations of living plant specimens as well as the assocated attribute information required to produce living collection maps. This feature class is not designed to replace an existing plant records system, but instead should be linked to one via the Plant Center ID field. This field should be populated with a concatonation of the Accession Number and Qualifier fields thus producing a unique ID for each specimen. This feature class can be used to create a very basic plant records system for new or previously uncataloged collections if desired. Each point should be classified as a Plant Center or Mass Planting using the Plant Center Type field. The Plant Center classification should be used for individual, stand-alone specimens, and the Mass Planting classification should be used to identify a species that is part of a group of plants growing together that may be too complex to map as individuals. Each point classified as a Mass Planting should have a corresponding polygon in the Mass Planting feature class that defines the boundary of the group of plants. This polygon may have one or many species inside of it. Each one of these species should be indentified by a seperate point the Plant Center feature class that is classified as a Mass Planting in the Plant Center Type field. This feature class is closely related to the Plant Center Annotation feature class. Annotation, or fixed map labels, are generated automatically for each point feature from the values in the Scientific Name and Plant Center ID fields.This feature class is also related to the Plant Maintenance, Tree Benefits, Tree Hazard & Health, Planting Bed, Planting Area, Planted Hardscape, and Collection feature classes, and corresponding IDs should be entered appropriately to link these feature classes together.

Description: The Mass Planting polygon feature class is used to delineate the boundaries of groups of plants that are too complex or dynamic to map as individuals, and is commonly used for meadows, wildflower gardens, large plantings of the same species, and groups of plants that have grown together. It contains feilds for specifying the number of different speices and the estimated number of individuals it contains. It is closely related to the Plant Center point feature class, and a point should be arbitrarily located inside of each polygon for every different species the polygon contains. For example, a polygon drawn around a mixed planting of California poppy and Purple needle grass would contain two points from the Plant Center feature class. One for the poppies and another for the grasses.

Description: The Plant Maintenance table is used to track work orders, which once completed can be coverted into a maintenance history record. It is related to the Plant Center point feature class so that each plant may have many work orders or maintenance history records associated with it.
Description: The Tree Hazard & Health table contains the fields necessary for performing a tree hazard and health assessment. It is closely related to the Plant Center point feature class meaning that any Plant Center feature may have one or more assessment records associated with it.It is recommended that health and hazard data be collected by a certified arborist. Once all data has been collected the Calculate Condition Rating Field and Calculate Hazard Rating Field tools in the Public Garden Tools toolbox can be run to produce condition and hazard ratings for all assessed trees.
