fire

n 2007 protected juniper-poplar forests and alien pine plantations were on fire near Kunfehértó-Kéleshalom. After the fire the monitoring of the regeneration was started in 2008 and since then it has been conducted once a year in both forest types. In the juniper-poplar forests we study the garsslands around 18 burnt and 18 unburnet junipers (along with adjacent reference grasslands) with 1m*1m and 5m*5m quadrats.

Fire is one of the most important human disturbance in Homokhátság and its impact is increasing due to climate change. We monitor the long term post-fire regeneration of grasslands in juniper-poplar forests in two sites (Bugac and Orgovány) in four stands respectively. We sample 10 grassland patches in every stand with five 1x1 m quadrat in each patch. The sampling has been conducted twice a year since 1997 in Bugac and 2002 in Orgovány. This dataset is the longest among the yearly sampled biodiversity datasets of KISKUN LTER.
