When two of us (Jifi Kolbek, Miroslav Sriltek) were working in North Korea on the Czech- Slovak field expeditions of the early 1990s, we did not think initially of comparing our results with the vegetation of surrounding areas or of writing a book. Our efforts mainly involved observing and documenting the vegetation as completely as possible and initial recognition of vegetation units. At first we focused on the most obvious vegetation types, but eventually also any important types that we could discern. Later we focused more on forests, since almost ali of northeastern Asia has forest...

Warm-temperate deciduous forests are "southern," mainly oak-dominated deciduous forests, as found over the warmer southern parts of the temperate deciduous forest regions of East Asia, Europe and eastern North America. Climatic analysis has shown that these forests extend from typical temperate climates to well into the warm-temperate zone, in areas where winters are a bit too cold for the 'zonal' evergreen broad-leaved forests normally expected in that climatic zone. This book is the first to recognize and describe these southern deciduous forests as an alternative to the evergreen forests...
