The botanical reserve is a part of the North Vidzeme Biosphere Reserve. It represents about 200 ha of unique coastal meadows with high habitat and species diversity. There were recorded 531 plant species, 42 are rare and protected in Latvia, 2 species are on the EU Biotope Directive 92\/43\/EEC list. Man has participated in the development of these littoral meadows for hundreds of years, by cattle grazing and hay harvesting. Recently, the intensity of grazing and mowing have sharply decreased, and the meadows are gradually overgrowing by reeds and shrubs. Wild cattle herd was introduced for some time in part of the grassland area in order to prevent overgrowth of meadows.\r\n","citation":null,"relatedIdentifiers":null,"status":{"label":"Operational","uri":"http:\/\/vocabs.lter-europe.net\/elter_cl\/10772"},"yearEstablished":1996,"yearClosed":null,"relatedSites":null,"siteName":"Randu meadows","shortName":"Randu meadows","siteType":"Stationary land-based site","protectionLevel":[{"label":"Category IV \u2013 Habitat\/Species Management Area","uri":"http:\/\/dd.eionet.europa.eu\/vocabularyconcept\/cdda\/IucnCategoryValue\/IV"},{"label":"Category V \u2013 Protected Landscape\/Seascape\/Area","uri":"http:\/\/dd.eionet.europa.eu\/vocabularyconcept\/cdda\/IucnCategoryValue\/V"}],"landUse":null,"images":[{"url":"https:\/\/deims.org\/sites\/default\/files\/photos\/Randu%2520plavas2.jpg","alt":"not defined"},{"url":"https:\/\/deims.org\/sites\/default\/files\/photos\/Sovita_Rusina_11.jpg","alt":"not defined"},{"url":"https:\/\/deims.org\/sites\/default\/files\/photos\/Solvita_Rusina_5.JPG","alt":"not defined"}]},"environmentalCharacteristics":{"airTemperature":{"yearlyAverage":5.68,"monthlyAverage":null,"unit":"\u00b0C","referencePeriod":null},"precipitation":{"yearlyAverage":642.2,"monthlyAverage":null,"unit":"mm","referencePeriod":null},"biogeographicalRegion":null,"biome":"grasslands","ecosystemType":[{"label":"Grasslands","uri":null},{"label":"Temperate grasslands, savannas, and shrublands","uri":null}],"eunisHabitat":[{"label":"Grasslands and lands dominated by forbs, mosses or lichens (E)","uri":null},{"label":"Low and medium altitude hay meadows (E2.2)","uri":null},{"label":"Mesic grasslands (E2)","uri":null},{"label":"Moist or wet eutrophic and mesotrophic grassland (E3.4)","uri":null},{"label":"Seasonally wet and wet grasslands (E3)","uri":null}],"landforms":null,"geoBonBiome":["Coastal","Terrestrial"],"geology":"The area began to develop in the postglacial period when the Earth crust rose and the sea gradually stepped back.

Communities of hydrophylous and hygrophylous species are found side by side with xerophylous meadow communities and dune vegetation. This diversity of habitats causes high species diversity.
