I have no problems with Scouts. It's the adults at training who come with lists of questions about requirements. Three weeks to the next round.
Some here have said ignore the requirements - usually by substituting better, logical words that could or should have been said but clearly were not. That is not an option for me, at least, when training Scoutmasters and SAs.
Some have said interpret words this way or that. If native means naturalized in historic times and wild means (individual animals) that are not pets, the biggest quibble goes away. (After all, the "Eastern Coyote" is supposedly a coyote-domestic dog hybrid.)
No one here has really dealt with "identify or show evidence of at least 10 kinds" That has been brought up three prior years running by someone at training. Many adults seems focused on finding the easiest possible way for a Scout to get rank.
CP, Mollusca is not a Kingdom. Animalia is. But I simply tell them this is not about binomial nomenclature or formal taxonomy. I only brought it up because whoever wrote the requirement knows far less than I do about classification and put a phyla on the same level as classes. I haven't dealt with classification since I was a lab assistant in Zoology as a history major (only one willing to deal with snakes) in 1964.
I don't believe I said Mollusca is a kingdom - I believe I said Mollusks are part of the Animal Kingdom - but perhaps I wasn't clear.
The requirement is to identify or show evidence of 10 different kinds of animals - the rest of that sentence is just filler really. Let's think about this from an 11 year-olds perspective. Animal means anything within the animal kingdom - whether its a phylum, a class, and order, a family, a genus or a species. This is a second class requirement - it's not Zoology Merit Badge (oh right, the BSA discontinued the Zoology merit badge). Think the common usage of the words, not the scientific uses.
As for 10 kinds - you need 10 kinds. A white-tailed deer is one kind. An American Robin is one kind. An Eastern Coyote (which appears to be a genetic mixture of Western Coyote, Western and Eastern Wolves (whatever "Western" and "Eastern" wolf means - Timber Wolf? Red Wolf? Mixtures?)) and Domestic Dog is one kind. So what is a kind? For most of us, it's 11-year old speak for Species. Here's the thing though - unless the BSA has defined it in the BSHB, then you just have to rely on people's common sense. If a Scout unit wants to accept Bear, Bird, Rabbit, Deer, Insect, Clam etc., which can encompass dozens to thousands of individual species, we just have to accept it.
I think the same goes for native plants. If you follow the definition of native that most conservation groups and government organizations use, then you're essentially limited to the plants that existed here before European settlers got here. If that's the case, then your standard field is likely to be out of bounds (there is a reason they are often called Eurasian meadows) because almost all of the species in them are not-native. For training purposes, I think you just have to spell out that at its most basic level, native means not-domesticated - it means no food crops, no flowers planted in gardens, no lawn grass and hope for the best because this isn't Botany Merit Badge (oh wait, the BSA eliminated that merit badge too).
When training, I think we need to start emphasizing more that people need to start thinking like 10-15 year olds. Its really not about the easiest way to reach rank - it is about not reading more in to the requirements than is stated.
