There are several projects that I've worked on for the BLM. The one I'm on now is called Seeds of Success. A part of the international seed banking program, SOS has a two-fold goal. The first is long term storage of seeds at the Millennium Seedbank in Kew England. The other is propagation for domestic use through the Bend Seed Extractory in Oregon.
I've found the project itself to be a mixed experience. On one hand, its an interesting task, finding species for the program and going through the process of collecting. I also deeply enjoy spending time in the field, and doing the collections themselves. Yet, the program is not flawless. There are parts of the protocol that are hard to apply to the desert region. One is the size of the population that the seeds are collected from. In many cases, there aren't enough plants to make a proper collection. Other times, there aren't enough seeds to meet the minimum of 10,000 while only taking 20% of the total seed volume. There are other difficulties, but those are two of the most prominent.
