Conserving Seeds in Arizona.

BOTANISTS with the Seeds of Success Program at the Desert Botanical Garden have collected seeds of native plants in Arizona for the past two years (2004-2005). These seeds are stored in seed banks and used for conservation and restoration. In 2004, low levels of precipitation resulted in few available plant populations for seed collection, especially annual plants. In contrast, high levels of precipitation yielded abundant populations for seed collection in 2005, including a greater percentage of annual plants. Based on observations and experience with over 155 collections from Arizona plant populations, we recommend that land managers and conservationists interested in seed collection use climate predictions to asses seed collection efforts. It is ideal to focus resources in years of above average precipitation although seeds collection is possible in almost any year.
