Robinia pseudoacacia. Black Locust is a medium-sized tree, growing up to 80 feet tall. It is easily recognized by its leaves and paired spines up to1/2 inch long. Black Locusts prefer sandy or rocky soil, and are most often found in old fields, open areas, woods, and streamsides.
The Black Death is thought to have originated in the arid plains of Central Asia, where it then travelled along the Silk Road, reaching Crimea by 1343. From there, it was most likely carried by Oriental rat fleas living on the black rats that were regular passengers on merchant ships. Spreading throughout the Mediterranean and Europe, the Black Death is estimated to have killed 30â60% of Europe's total population. In total, the plague reduced the world population from an estimated 450 million down to 350â375 million in the 14th century.
