NATIVE GRASS ECOTYPES AND THEIR REVOLUTIONARY IMPLICATIONS FOR
GENETICISTS, BIODIVERSITY, CONSERVATION, TAXONOMY, EVOLUTIONARY SCIENCES, AND ECOLOGICAL RESTORATION.
--Implications for genetic studies
--Implications for biodiversity, conservation and taxonomy
--Implications for ecology and ecological restoration practitioners
--Implications for evolutionary sciences
--Ecotypes and who needs them
--Establishing ecotype refugia: The Native Heritage Program.
--A history of ecotype and related research: 1880-1996, in chronological order.
--Photos of six native grass (Bromus carinatus) ecotypes from the San Francisco Bay Area
The concept of setting aside Native Heritage Preserves throughout
the United States could be developed state-by-state, with a baseline
of one for every 225 square miles. For example, you would divide
the area of Maryland (12,407 square miles) by 225, then a minimum
of 55 refugia would be needed for that state. This formula would
even work well in small states like Hawaii where there is known
to be a large amount of biodiversity: a minimum of 48 refugia
for the island chain. We need to start thinking now: "what
is the minimum we are going to preserve for the future?"
Within these preserves, or refugia, we would be banking future genetic material, models of the community structure, and wonders for future generations to discover. These preserved refugia, like the relict areas in India researched by Gadgil & Vartak (1976), may end up being the only intact examples of native ecosystems in the future. We when we preserve 680 relict refugia for California's future, this only represents one acre in exchange for every 10,000 we've taken for our own use.
Every seed company that sells native grass seed and every person who plants native grass seed or plants depends on the existence of the relict grass stands for their original genetic material. Now is the time for the relict stands to depend on us, for their continued survival. In exchange for the gifts they have given us in the past, we must guarantee that their gifts will be available for the future.

Greene lacked the concept and term "ecotype", which was not invented or commonly used until two decades later; so Greene organized his eoctypes into 112 "species". His work has been generally ignored and even scoffed at, because taxonomist even to this day do not want to believe that there are possibly 112 species of California poppy. But if we now recognize his "species" as ecotypes, then it makes his paper an important historic and pioneering document: valuable for conducting ecological restoration of California wildlands, today and far into the future.
