Is making lists of plants and animals you see really so interesting, and worth the trouble?
First of all, the best way to celebrate a good sighting, such as spotting a rare hawk or an endangered wildflower, is to list it! Once a good sighting is in the list, you can return to the list again and again and remind yourself that to accomplish this sighting you were perceptive enough, smart enough, and lucky enough to see something special. In other words, the listing will be exactly like a hunter's trophy.
Lists also help you learn. Let's say that one day word gets out that you know the local street trees, and the Scout leader up the street asks you to lead a field trip showing all the little Scouts how to identify various species. Not to worry. Already you have street-tree lists reminding you of which species are to be expected. Moreover, your notes accompanying the lists remind you that Sugar Maple leaves have U-shaped sinuses, while Red and Silver Maples have V-shaped ones. And that Black Oaks are the ones with extraordinary "stellate," or branched, hairs on their lower leaf surfaces.
Beyond such incidental advantages to making lists, probably the most important byproduct of list making occurs during the list-making process itself. For, in making the mental effort to organize your discoveries on paper or in computer files, you're obliged to organize your brain with regard to the subject at hand, and you remember what you've seen better.
You'll discover an additional service your lists provide when you join with other naturalists at meetings or on organized field trips, bring out your notes, and delicious discussions and debates arise about what you've listed!:
