INDIVIDUAL TREE DETECTION FROM UAV LIDAR DATA IN A MIXED SPECIES WOODLAND

A historical drought series (since 1200 CE) for Shenyang, NE China, shows 20th century droughts comparable in magnitude to recent severe droughts. Drought resilience driven by early 20th century societal/cultural changes reduced loss of life compared with the 1887 and 1891 droughts. A longer temporal analysis from integrated precipitation and historical records shows an earlier onset to droughts. Regional standardised precipitation indices could provide early warnings for drought development.
