For the love of oaks
For the love of oaks: An identification party
Dates: Feb 16, 2023 | 5-6 PM (PT)
Details: Virtual ID Party
Registration Link: https://bit.ly/3CdezZW
Happy New Year and Welcome 2023!
First, I’d like to take this time to thank you all for a fantastic year with the launch of our project in the Summer. I am excited to continue our work to map (young) oaks throughout California with the year ahead! Love will be in the air this February on our new Quercus Quest. Don’t let your love for oaks end after Valentines Day! Help us reach our goal to get as many Quercus observations to Research Grade as possible! Anyone who is interested in an hour of socializing and collaborating on iNaturalist are invited to join.
Currently, the project has around 75,000 observations but only about 63% of those observations are at Research Grade. Additionally, there are approximately 15,000 observations identified only to genus level. Help us in resolving these identifications, so we can add more Research Grade observations to our project!
We will have a panel of experts to facilitate the conversation and we can work collaboratively to help identify any tricky observations. We encourage anyone to come join us! This online event is open to identifiers of all experience levels. It would also be great for those with observations that need to be identified to join us and see if anyone in the group can help! In addition to all the fun that comes with oak IDs, we will have a live raffle throughout this event so everyone participating will have a chance to win an oak t-shirt and a California OakWatch Pin!

Hi! I think a big issue is getting to species level on the White Scrub Oaks. The introgression and variability makes this very difficult, and I would say impossible with the average Oak ID upload.
In Los Angeles we have 5 species of white scrub oak: berberidifolia, dumosa, durata var gabrielensis, engelmannii, John-tuckeri, and potentially Cornelius muelleri. To make things more complicated douglasii and lobata are also mixed in. During fall, I looked at the trichomes of over 100 white oaks and it Meade things more difficult. I regularly see trichomes from other species show up unexpectedly, including outside of the plants known range. Here's Quercus John-tuckeri, based on trichomes, in the Verdugo mountains: https://www.inaturalist.org/observations/140299561
Its also possible that morphological characteristics aren't very useful in species determination for white scrub oaks: " At the same time, some individuals that were assigned to one species based on nuclear microsatellite markers possessed morphological variation clearly within the distribution of a different species (Figure 5B). In fact, we have other unpublished data showing that individuals that are assigned to one species based on a set of neutral markers will look entirely like a different species. One dramatic example is a scrub oak with multiple stems and small leaves that might show 95% genetic assignment to Engelmann oak (Sork, personal observation)." (Sork et al, 2016)
The Red and Golden oaks are generally easy to ID but until we get White Scrub Oaks figured out, I think the amount of "Research Grade" IDs will remain low.

5 PM start time on a week day is too early for me, but maybe I'll catch the end.
I will try very hard to attend! I teach sewing sometimes in the evening and this is one of those days, sadly.
Thanks for the info and links, Matt! @plantsoncolors
Would be great if y'all could make it! I'll be sure to do the raffle towards the end of the hour in case y'all drop by.
@arboretum_amy @marivillasol
I missed it by 1 day :(
@jorgejordan No, it's today, right now! 20 minutes left
For some reason, I just got the notification right now! A little late:)
I had a similar issue as Cat. Just got the notification today. Hope it went well!
hmmm that's interesting! @catchang @sapienshane
We will have more of these soon! We still have plenty of shirts and pins to give away (:
Awesome!
Yesss shirts
