  • Red Hills in California: chaparral covered hillsides. These are foothills of the Sierra Nevada.
    Made for my Intro Bio courses at University of the Paicific
    Note: I stumbled a bit and suggested cyanobacteria are protists, they are not! A lichen is a symbiosis between a fungus and a photosynthetic cyanobacterium (bacteria) or a photosynthetic green algae (protist in archaeplastida)

    I'm not in the class but am very curious, why are the flowers yellow?

      there could be multiple reasons, the one that is relevant to my course is that they could be attracting the same local pollinators!

      @@ariverapacific That makes sense. I just started taking a horticulture certification course. It's a fun topic to learn about.

    A lot of beautiful scenes and interesting details, but other than the first and last image, the majority of this video details grassland and conifer habitat, not chaparral.

      Great point, Red Hills is considered chaparral because the dominant species are the fire and drought resistant shrubs that typically make up chaparral. Sierra foothills chaparral ecosystems look very different from those found in Southern California, which almost completely lack trees. In the Sierra Foothills and Coastal Northern California, Conifers or Oak trees are common members of the chaparral biome. Hope this is helpful info for you!

      If you want to see a conifer-dominanted habitat check out my video on the Taiga

      @@ariverapacific Thanks for the reply! You're definitely correct that there are some pines found in central and northern chaparral, in particular Pinus sabinana in the Sierra foothills and serotinous Coulter pines further south, but they are sparsely scattered and are more of an oddity than a significant component. All along the western slope of the Sierra Nevada foothills there's large stands of chamise chaparral where pines dare not tread. In wetter, mountainous areas like Humboldt and southern Oregon you'll find chaparral species like manzanita under conifers, but those areas are considered forest rather than chaparral.
      Oaks once were significant components of sage scrub shrublands, particularly along the central coast, but much of this combo has been destroyed by overgrazing and too many fires.
      No one has ever definitively quantified how many trees a chaparral habitat can have before it is no longer chaparral, but generally speaking, chaparral is dominated by shrub species that form a contiguous canopy. Nature doesn't like lines, but by definition, trees are outliers in chaparral.
