EUNIS habitat types of biomass and LAI of samples of Orgovány LTER grasslands (KISKUN LTER)

The dataset contains the EUNIS habitat types of the sampling plots of the Orgovány LTER (KISKUN LTER) grassland biomass and LAI measurements. The aim of the yearly biomass and LAI measurements in the grasslands is to study the effect of weather to the plant production along a productivity gradient. Aboveground living plant biomass data from 24-30 grassland patches in Orgovány region of Kiskunság (Kiskunság National Park) along a productivity gradient from open sand grassland to reedbed, yearly from 2003 to 2012, were sampled approx. at the time of maximum aboveground biomass. The size of the patches are 20 to 50 sq-m, and each year one 0.5 by 0.5 m sampling unit is selected within each patch. The patches are permanent ones; some of them were omitted and replaced because of disturbance in several years. The total aboveground living plant biomass and LAI data  are submitted in HU_SI001199_lai_biomass_20130508 dataset, and the abovegroung biomass data of plant species are submitted in HU_SI001199_species_biomass_20130508 dataset.
