Abstract:V svetu invazivne tujerodne vrste rastlin (ITVR) povzročajo mnoge spremembe v okolju. Za zatiranje ITVR je znanih precej metod, primernost posamezne in posledično tudi uspešnost pa sta odvisni od vsakega primera posebej – predvsem od cilja, ki ga želimo doseči z zatiranjem. V študiji smo spremljali zatiranje navadne barvilnice v okviru nege mladja, tj. z rezjo pri tleh. Študija je potekala na objektu s površino 2,82 ha, dela so izvajali trije delavci. Cilji študije so bili ugotoviti porabo časa na površino in pridobiti manjkajoča znanja na področju izvajanja dodatnih ukrepov pri negi mladja. V povprečju so delavci za en hektar obžetve potrebovali 18,8 ure produktivnega časa. Po simulaciji študije na osemurni delavnik faktor neproduktivnega časa znaša 1,39 (σ = 0,053) in je nižji od priznanega državnega faktorja neproduktivnega časa (1,58) za sečnjo. Pri interpretaciji rezultatov je potrebna previdnost, ker so pri kratkotrajnih (manj obsežnih) študijah pogosto podcenjeni faktorji neproduktivnega časa. Teoretični izračun, ki temelji na linearni regresiji podatkov, kaže, da je za obžetev enega hektara v celoti potrebno okrog dvaindvajset ur. Kljub že tako nizkemu faktorju neproduktivnega časa je še rezerva za optimizacijo delovnega procesa, vendar so za to potrebne dolgotrajnejše in obsežnejše študije časa.

Title:Control of invasive alien species American pokeweed : time consumption and potential improvements in silviculture
Abstract:Invasive alien plant species (IAPS) are causing many changes in biocenoses around the world. Many methods are known to control IAPS. The suitability of the method and its success depends on each individual case – the main goal that is to be achieved by suppression. In the study, we observed the suppression of American pokeweed plants as part of silvicultural interventions in young forests by cutting American pokeweed at ground level. The objectives of the study were to determine the time spent per area (hectare) and to gain knowledge about the combination of silvicultural weed control and IAPS suppression (eradication). On average, labourers spent 18.8 hours of productive time managing one hectare. The non-productive time factor was calculated using our collected data based on an eight-hour shift day with a 30-minute lunch break. The calculated factor for unproductive time is 1.39 (σ = 0.053), which is below the nationally recognised and approved value (1.58) for timber harvesting. Caution is required when interpreting these results, as the factors for unproductive time are often underestimated in short-term studies. The theoretical calculation, which is based on a linear regression of the data, shows that a total of around 22 hours of labour are needed to manage one hectare. Despite the already low non-productive time factor, there is still room for optimising the work process, but this requires long-term time studies.
