A catalog tracks the objects you collect.
It assigns a number (starting with 1) of all the specimens such as pine cones, rocks, etc. that you pick up during your field observations.
This is a separate section of your Grinnell field journal or a separate book all together.
At the end of the year, the print format record is closed out. The last page of a year ends and a new page is started for the new year.
Professional naturalists employed by museums donate their collections to their employing institutions to preserve specimens. It is often a condition of their employment and they have legal licenses to collect.
Please note: I only pick up fallen objects. Such as pine cones, leaves, shells, acorns, nuts, a feather, rocks, etc. I don’t pick live plants or bird’s nests.
Setting Up the Page
Title each page “Catalog”.
Label or tag each specimen you collect.
For each specimen tag or label. Include this same information in the catalog.
- item number
- date collected
- location of collection
- collector’s name
- identification of object
A note about identification for the hard-core scientists among us. For professional naturalist collections, a taxonomist, who specializes in species identification will identify a specimen. The field collector may not. A professional field collector may sometimes write the species scientific name on back of the label – in pencil. In case they make a mistake. But this shouldn’t stop us amateurs.
If you draw, photograph or attach an object to your nature journal page, including this information will be very helpful in learning about your area.
A record of where you found or collected an object makes that object more useful to your nature study.
I had a box full of leaves that I had collected over the years that had no record of where I found them. I could only say this is a “Scarlet Oak leaf”. But, couldn’t return to the tree to see if it was still there or if there was any new to find out.
I eventually composted my collection. It had limited nature study value.
