Invasive species versus Californian Natives Competition Trial Update – Census 2

I want my final paper to be useful for and applicable to restoration ecology.  This led me to inquire what data I should collect for my second census. My germination rates are up, and all four species are present, so would relying on number of individuals and biomass of each species per pot be enough data? I decided that since I am using light as a limiting factor I must include height in my data; the plants may have somewhat similar biomass, but if it is due to leggy growth in the shaded pots then it will be important to note that although biomass was similar resource allocation was not equal. Are great amounts of leggy, weak, and nutrient deficient plants with few leaves better for ecosystems then having fewer shorter but thicker, more leafy plants?  I measured the number of individuals per species per pot, alongside with the height and number of leaves the tallest member of each species had per pot. I have yet to analyze these numbers, but did notice trends when doing the census!

Side note: I conducted a germination experiment in the greenhouse prior to using these seeds, and have let them grow out. My Phacelia tanacetifolia is growing a beautiful flower!
