Death to all Holly?

Hey Casey and Alex! I'm a new ISA certified arborist for my municipality and one thing I hear a lot of is new residents wanting to clear cut their lot so they "can see it better". When their request is denied, I'm told that its "all invasives". Here's my question: when it comes to holly, how do you discern English holly from American holly? I'm on the Olympic Peninsula and have seen several different varieties of holly. The older plats have holly that was purposefuly planted a long time ago, and of course the invasive English holly can easily be spotted in our forests. Thank you, Robin

Are gingko seeds really naked?

Hi there - can someone please explain to me how the seed of a gingko tree is considered to be naked when it contains a fleshy, fruit-like coating around the "nut"? I am struggling to understand how botanically it is considered a gymnosperm.

Dead leaves that stay on the tree

Hi Casey and Alex! I live in the eastern US where there are a lot of deciduous trees. In the fall, most of these trees' leaves turn colors and then quickly drop off the tree. But some kinds of trees hold onto their dead leaves through the winter and into the spring. I especially notice beech trees and oaks doing this. Why do some trees hold onto their dead leaves? Is there an advantage or disadvantage to doing so?

Making science accessible to all!

Hey Casey and Alex - First - Wow I love this podcast! Second, related :) I love this podcast for many reasons, but largely because you all make science accessible to a broader population. I am a researcher who struggles with making my work accessible to non researchers and often times I work with a designer to help me make my results and findings more consumable. Could you share any thoughts, tips or tricks you have on this topic? Or just on the topic of the value of multidisciplinary collaboration? I feel like your musician + science person combo is so useful and perfect. Sort of like what Freakonomics did (economist + musician). Anywho, thank you!!

10yr old son has tree question

My son, Gus, and I listen to your podcast ALL THE TIME. He asked me to email you this question: What would be the first tree you would climb if you could climb any tree in the world? Thanks for the amazing podcast! Sincerely, Felicia
