Fire Hazard: Undesirable Ecosystem Function of Orchard Vegetation

Fires will become an increasingly frequent perturbation even under the conditions of mild climate zone and interfere with agricultural landscape. Fire is a natural phenomenon, depending on ecosystems, vegetation may develop contribute to occurrence spread fire. Vegetation sour cherry orchard located in climatically dry South Moravian Region, Czech Republic (CR), was evaluated. assessment performed using phytocenological relevé. In each variant, 10 relevé were recorded. Coverage found species estimated directly percentages. Moreover, maximum height stand measured for type plant. Biomass individual plant calculated, biomass index (IB) equation. The IB values treatments processed by employing multidimensional analysis ecological data. Different management practices change diversity thus fire hazards conditions. Grassy interrow has most grass during entire season, therefore represents greatest hazard important grasses include Arrhenatherum elatius, Dactylis glomerata, Festuca pratensis, Lolium perenne, Poa pratensis. On contrary, bare soil are suitable annual species, this place highest changes number growing season. combined warm weather increases hazard. Annual perennial have very good potential production biomass, which nature orchards actual start its subsequent spread, however, other environmental During hot weather, dead accumulate resulting increasing large wildfires. Varied lead higher make orchards, islands biodiversity
