This volume includes over 10,000 citations to literature published during the last ten years about plant conservation at all levels, local, national, and international. Its scope ranges from highly specific papers on individually threatened plant species to more general papers tackling conservation strategy, policy, and law. Reference citations are grouped into three sections, General, Regional, and Country. For the larger countries also followed by state or province. Each citation is numbered in the left-hand column, making it easy to find specific references using the subject indices given at the end of the book (an index on plant names, one on families, and a geographical index).
