Plant micro-reserve

A plant micro-reserve (abbr. PMR) is a type of small nature preserve that targets rare or threatened plant species, protecting the species' main populations from further decline. They also serve as hotspots for biodiversity monitoring, seed collection, and plant management. A micro-reserve centers around a single habitat or plant habitat, and is usually smaller than 20 hectares. A PMR may be located on public or private land, and is obtained by a governmental agency by a voluntary turnover of the area. They are managed by national, regional, or local governments, or by individuals, families, or non-governmental organizations. First piloted in the Spanish province of Valencia in 1990, the concept was subsequently funded by the European LIFE programme. It has since spread across Europe, including large networks in Bulgaria, Latvia, Cyprus, and Greece.
