Most semi-natural open habitats in Europe have been traditionally maintained by anthropogenic activities, such as grazing or mowing, preventing the establishment of woody vegetation. These habitats ...harbour a remarkably rich biodiversity in terms of both plant and animal species, but are also highly threatened, mainly by agricultural intensification and land abandonment. With this Editorial we introduce a Special Issue initiated by the European Dry Grassland Group (EDGG) at the Open Landscapes Conference (Hildesheim, 2013) and the 11th European Dry Grassland Meeting (Kulikovo Pole, 2014). We aim to give a short introduction to the current conservation status, significance and research of semi-natural open habitats in Europe and present the collected articles of the Special Issue. These papers cover a wide range of different semi-natural open habitats, including wood-pastures, heathlands, steppes, semi-dry and dry grasslands across the Palearctic region and address issues related to the assessment methods, threats, management and restoration of these habitats. We conclude that, in order to ensure their conservation and to monitor the changes in open habitats, integrative approaches are needed that take into account not only vegetation records, but also multiple animal taxa, abiotic factors, management practices, ecosystem services and modelling simulations for anticipating possible future scenarios. We also recommend that decision-makers should support actions to conserve open habitats in Europe by addressing such major challenges as the encroachment of woody vegetation. We are convinced that the present Special Issue will contribute to a better understanding of ecosystem functions and support the biodiversity conservation and management of semi-natural open habitats.
Večino pol naravnih odprtih habitatov v Evropi tradicionalno vzdržuje s svojim delovanjem človek, kot na primer s pašo ali košnjo, in tako preprečuje zaraščanje z lesnato vegetacijo. Ti habitati so biodiverzitetno zelo bogati z rastlinskimi in živalskimi vrstami, vendar tudi močno ogroženi zaradi intenzifikacije kmetijstva in opuščanja obdelave. V uvodu želimo predstaviti posebno številko revije, ki jo je vzpodbudila Evropska skupina za suha travišča (EDGG) na konferenci Open Landscapes (Hildesheim, 2013) in na 11. srečanju skupine (Kulikovo Pole, 2014). Predstaviti želimo trenutni varstveni status, pomen in raziskave pol naravnih odprtih habitatov v Evropi in zbrane članke v posebni številki. Ti članki obravnavajo širok nabor različnih pol naravnih odprtih habitatov, med njimi gozdne pašnike, resave, stepe, pol suha in suha travišča palearktične regije in obravnavajo metode njihove presoje, njihovo ogroženost, gospodarjenje in obnovo. Zaključimo lahko, da moramo poleg vegetacijskih popisov upoštevati tudi številne živalske vrste, abiotske dejavnike, načine gospodarjenja, ekosistemske usluge in modeliranje predvidenih možnih prihodnjih scenarijev, če želimo zagotoviti njihovo ohranjanje in spremljanje sprememb. Predlagamo tudi, da nosilci odločanja podprejo prizadevanja za ohranjanje odprtih habitatov v Evropi z obravnavanjem tako velikih izzivov kot je zaraščanje z lesnato vegetacijo. Prepričani smo, da bo posebna številka prispevala k boljšemu razumevanju ekosistemskih funkcij in omogočila ohranjanje biodiverzitete in gospodarjenje spol naravnimi odprtimi habitati.
Mestna občina (MO) Koper je ena od študij primera v evropskem raziskovalnem projektu PLUREL1. Namen projekta je razviti nove strategije in orodja za načrtovanje ter napovedovanje prihodnjih rab ...prostora. Za MO Koper so bili ≫preigrani≪ trije scenariji mogočeprihodnje rabe zemljišč, ki so bili na podlagi številnih kazalcev in trendov prostorsko opredeljeni z modelom MOLAND2. Model temelji na prostorski dinamiki, glavna spremenljivka v njem pa je raba zemljišč. Na podlagi različnih scenarijev se z modelom projicirajo spremembe rabe zemljišč v prihodnosti glede na vrsto rabe in sprememba se prostorsko opredeli. : The Municipality of Koper is one of the case studies in the European research project PLUREL. The project isaimed at developing new strategies and tools for future land use planning and prediction. Some scenarios for possible future land use have been prepared and spatially defined, based upon different indicators and trends, using the MOLAND model. The model is basedon spatial dynamics, a key variable being the land use and the state of each cell is its land use class (e.g. residential, industrial, commercial, forest, agricultural land etc.). Based on the developed storylines of the scenarios, the model simulates changes in future land use and spatially defines the changes.
