Thanks! Could you explain what the petiole is a little more?

I thought that White Ash has the longer petiole (like below) and oregon ash has the absent petiole. I don't know about green and black ash.\

Oh I was just talking about white, green and black ash. I'm not sure about oregon but I did check the black ash and I don't think it has a petiole.

You don't really have to worry about petiolules on Black, so I'll go to the other two. Just remember that there is none.

Green is about 1/8" long, while White is 1/4" to 1/2" long, so there is a definite difference if you look hard (this may be hard to tell depending on picture and quality, so go with your gut! )

That is about all my book has and I'll I usually use to identify. It is pretty hard to identify with the seed (a samara) though White and Green seem to have a "notch" while Black does not. Hope this helps!

Thank you so much!

Question for everyone...

What book(s) did you use?
I used this fabulous little guide, though it was missing a few trees from the list we added to our notes.

If you look at the earlier posts, I think on pages 32-35, I think people talk about what kinds of book are best for people with different background knowledge on trees.

Here's a helpful little graphic I found as far as the ashes's fruits go.

Btw, can anyone help me find the differences of the Eastern White Pine, Jack Pine and the Red Pine based off solely their needles. I think the Eastern White Pine has more needles in a bundle than both Red Pine and the Jack Pine but I'm not for sure. And also, both the Jack Pine and Red Pine have the same amount of needles per bundle so it's almost impossible to tell the difference.
Can anyone help me?

Also tell me how you found out (what source, wikipedia, observational data, etc.)

Thanks!

Well Eastern Wite pine is easy because it is the only one iwth 5 needles in a bundle. Then Jack Pine and Red Pine both have 2 per bundle, but jack pine needles a re much shorter (1.5 in. Long) than red pine needles (5 in long).i got this info from my research for forestry, and mainly from the sibley guide to trees. Hope this helps!

Thanks and are you sure it is 5 needles per bundle on the Eastern White Pine because on the pictures I see it looks like there are four

I have been wondering, in this event... will they be asking questions on general forestry knowledge or specific questions about the tree we are asked to identify. For example, will they ask questions like what is the average amount of wood used per person in the us per day, or show a picture of a ginkgo and ask where is this tree native to?

please help,----> confused freshman

Yeah, I'm positive cause both the sibley guide and audobon said they had five. It does look like four sometimes though, so its hard at comp to identify pines especially when they give bad photos!

They should ask specific questions about trees you have to identify, but in my regionals, they also asked some questions about general knowledge, which we werent expecting (for eg: what is atp, how do leaves/branches/roots contribute to tree, label a diagram of a tree). They weren't supposed to do that, but I would know some general knowledge about trees just in case. More often than not they will ask about specific trees, and their characteristics.

This is an interesting question that leaves test writers with some interpretation. The most reliable way of finding out would be to ask team members who previously competed in ornithology what your specific regional/state test was like, because test styles do vary from region to region.

My personal interpretation of the rules is that the vast majority of questions will be ID and related questions, rather than general tree knowledge. You can see this implied in the Description and 3a-3c in the manual.

Seeing as you're from NY, there is a good chance that the state test this year will be similar in format to the previous two years, with either a timed Powerpoint or two minute stations and maybe 1 or 2 general knowledge stations at most.

Is there anyway besides range for distinguishing between fremont cottonwood and eastern cottonwood? I noticed that the leaves look surprisingly similar...
Fremont cottonwood:

Eastern cottonwood:

Leaves of Eastern Cottonwood is much larger than Fremont Cottonwood.
