Botany Field Observations

Summary

Plants form the link between the abiotic features of landscape (rock, soils, water, etc.) and the
biotic world. California has a very rich and complex flora, making species identification
sometimes very difficult. This activity provides students with an opportunity to students to begin learning how to identify plants in the field. In addition, students will learn that even if they don't know the identity of a morphospecies (its specific epithet), they will still be able to record how many individuals of each morphospecies type are present in a location, making it possible to measure
both density and diversity.

Learning Goals

Content/Concept Goals:

Students will...

  • Begin learning how to identify plants in the field.
  • Differentiate the major lineages of plants (e.g., ferns, gymnosperms, monocots, eudicots, etc.),
    which can be sufficient when describing community composition.
  • Consistently identify morphologically similar individuals into groups called 'morphospecies', which are often good approximations for true genetic species.
