The Ecological Value of California Walnut Woodlands to Avifauna with Natasha Khanna-Dang - 8/22/2024
A program of the San Gabriel Mountains Chapter of the California Native Plant Society
While supporting local community efforts in Northeast Los Angeles to use tree protection ordinances as a means of halting development projects, Natasha Khanna-Dang found that there was a gap in research on understanding how the Southern California Black Walnut tree and its associated habitat are important to wildlife. In order to address this gap, she conducted a bird foraging study to quantify the ecological significance of key tree and shrub species in California walnut woodland habitat. She studied plant community composition, and the role that plants play within food webs for birds.
Natasha shares her research findings on the importance of these woodlands to the larger ecosystem. She discusses how ecological research can be intersectional by addressing both conservation and social justice issues. Natasha's research was directly inspired by the anti-gentrification efforts of community groups affiliated with Takaape' Washuut Black Walnut Day in Northeast Los Angeles.
Natasha Khanna-Dang recently completed her Master of Science degree in Environmental Science at California State University, Los Angeles. Natasha also works as a graduate research assistant in the Wood Lab of Urban and Avian Ecology at Cal State LA which involves managing a large-scale food web study to critically evaluate the role of native and nonnative oak trees in structuring urban food webs, composed of plants, insects, and birds, in Los Angeles County.

Oaks are an important element of the California landscape. As a group, they are one of the most widely recognized plants in southern California. While a number of the tree species are fairly distinctive and easy to tell apart, the shrub species can be challenging to separate. The white oak and scrub oak species are especially difficult; not only do they look similar but they are a promiscuous l...

    I had no idea of White Sage stealing on public lands was such thing. I have seen it being sold all over the south west in shops and flea markets etc. I really like to see the Indian tribes and wealth casinos take a more proactive roll to bring this to the for front. I think the public who purchases White Sage have no idea where it is truly sourced from. It wouldn’t take that much effort to really find out who and whom are really doing the illegal taking of this.

      @@davedave6952 Thing is, we have an idea of how old the earth is, roughly 4.5 billion years. There are several dating methods that are used, two of the more well known are the radiometric and potassium-argon dating methods. They're commonly used to date igneous or volcanic rocks. The carbon dating method is used to date organic material that once belonged to living things like bones or teeth. If you want to trust in the Bible, I'm not going to stop you. Though you're going to have to accept that the earth is a circle, yet has corners, is supported by pillars that stand on water, has a firmament that's composed of some unknown material that holds back an infinite amout of water, that the stars and planets are just dots on this firmament.

      @sigisoltau6073 4 หลายเดือนก่อน

      @@davedave6952 Well we know the earth's age fairly accurately. I say that because most of the earth's oldest rocks have been destroyed by tectonic forces or erosion. Those that remain have been dated to 4.3 billion years, 8n Australia zircon crystals have been dated to 4.4 billion years. So the earth is at least 4.4 billion years old, if you don't count meteorites. Meteorites are from space and the solar system, but since the planets formed from them, you can date them as well. Meteorites as you know have different origins, those that came from asteroids are about 4.5 billion years old, those from planets are slightly younger.
