Plant Inventory Finished and Records Labels Arrive!

During the past month, I have been working on completing a thorough inventory of all the plants we have on the grounds.  As a museum with living collections, a botanic garden needs to not only record information about a plant upon its arrival but also continually evaluate the plant over time.  This is valuable not only because it allows us to know the current state of any of the plants in our collections, but also because we develop a history for each plant.  To give you an idea about what inventory entails, here is an example of a (completed) sheet I carry around with me to record information.  These sheets are created directly from our plant records database, BG-Base:




Once all the information is collected, I need to enter it into BG-Base, primarily into the "Plants" table of BG-Base.  Below are examples of some of the screens I work with when completing data entry:

^Location, number of plants, condition, flowering/fruiting stage and other notes go into this window of the Plants table.


^How complex the BG-Base window can get if I'm making edits across tables and performing queries, and yes, it's running on a Mac : )

BG-Base is a "relational" database, which means that there are many tables tied together so that data from one table can be displayed in fields of another.  While this is cool, it sure makes for a lot of work in terms of data entry and making sure the integrity of all the connections between tables are maintained whenever edits are made.  A large computer screen is definitely a BIG help.


On a related note, our records labels have finally arrived!  Records labels are a great help when it comes to keeping accurate track of the plants in our collections.  Each plant or mass of plants is a unique entity with all its information in our database, so it is crucial to accurately maintain this link, which is similar to the link our social security numbers provide from ourselves to information about us.  In both cases, if that link gets broken, it's bad news - the former being clearly far more serious a matter.  Our records labels include each plant's scientific Latin name, source, and accession number + qualifier - its "social security number."  This number allows me to double-check that the plant I'm looking at is the plant on my sheet I want to inventory and also acts as a key to access all the data we have for a given plant.  The labels are primarily useful to our Gardens' staff but horticulturists, botanists, serious gardeners and curious guests will all find them useful if they want to know more about a specific plant.  Here are a couple pictures of the glimmering labels (563 in total).  You can see parts of the stakes the labels are attached to in the second photo; they resemble a key chain ring attached to the top of a 6-inch metal stake.


Awesome, right?  Our table in the office reminded me of a drug-bust table with the lines and lines of these records labels I have out to be placed.  If plant labels ever became illegal, the authorities would certainly be able to put together an impressive presentation of all the labels they find after busting our notorious botanic garden operation.  I'll have to work on my buffness, though, if I'm to play the part of the bad dude behind the table with armed guards on either side.  With hopes that plant labels maintain legal status for the foreseeable future, I will be placing these labels by their corresponding plants over the next couple weeks - another big milestone in progress for our Botanic Gardens.

Say Cheese!!

Or...if you're staying with us here at Kona Kai, "Say Keys!!" works even better and no doubt makes your smile a little bigger and brighter with the reminder that you are really, truly, actually here, in our little slice of paradise.

Photographic documentation of plant collections is a very nice asset for a botanic garden.  These pictures not only serve as memories, but as horticultural and botanical resources as well, providing a visual history of the gardens and documentation of their development.  For specific plants, along with inventory (taking measurements of the plants and evaluating their condition), photographs allow others to see exactly what the evaluator saw and make their own observations and judgments of the condition of a plant.  In addition, notes like, "serrated leaves, small red flowers and oblong purple fruit" don't provide too much detail, so pictures provide a great supplement to descriptions, especially when one does not know all the correct botanical terminology to adequately and accurately describe the plant.  Below is an example of flowers from Phoenix roebelenii (pygmy date palm) that might be hard to adequately describe:



Pictures are also useful when it comes to diseases, pests, or nutrient deficiency.  If one does not have an extensive knowledge of these subjects, it is difficult to make guesses during inventory as to what might be wrong with a plant.  It's not very helpful to have generic notes that say, "yellow spots on leaves" or "some type of bug infestation."  Pictures are useful in that they provide a ready reference for follow-up in the office with either print or electronic resources to help determine exactly what the condition is and the appropriate remedial action to take.  Here's an example of a condition on a frond of Thrinax morrisii (Key thatch palm) that might be difficult to accurately guess the cause of and/or describe in words:



Another benefit of photographic documentation is convenience.  Perhaps you need to double-check the identity of one of your plants but it only flowers/fruits once a year for a short period of time.  If you know which parts of the plant are important to photograph and what notes to take along with them (i.e. notes on dimensions, flower and fruit characteristics, etc.), you can evaluate the identity of a plant from the office at any time of the year.  This is especially helpful, too, since many plants cannot be found with both flowers and mature fruit available to analyze at the same time.  I was lucky enough to catch some of our female Zamia integrifolia (coontie) coning:



Photographs can be used to track the growth of individual plants when taken at regular intervals, depending upon the growth rate of the plant.  It's almost like having a collection of pictures of yourself from when you were a baby all the way to your current age.  These pictures are a nice supplement to measurements taken during inventory.  Having only your height and weight each year of your life certainly leaves out a lot of details that pictures are able to capture, and I feel the same way about plants; height, canopy spread and diameter measurements only paint a very generic picture of a given plant.  We've begun tracking the growth of shoots of our breadfruit (Artocarpus altilis) with photographs after it died back to the ground during a cold snap this past winter:



It is imperative that an organized cataloguing system is developed for the plant pictures.  BG-Base helps us with this by providing a way for pictures to be associated with specific records in the Gardens' database.  I also make sure that each picture is labeled with the date it was taken, scientific name of the plant and its accession number.  Without knowing this information, the pictures lose value.  It would be much like having an art gallery with little or nothing known for certain about each work.

As they say, a picture is worth a thousand words.  Often words are not sufficient to adequately describe everything of note about a plant and it is more helpful, efficient and accurate to take pictures in addition to describing and measuring the plant.  A well-documented and organized collection of photographs provides an important objective perspective of the collections and also make our records more interesting and valuable.
