During the first seven years, considerable changes within the catchment were observed. Both internal and external factors could be identified as driving forces for the formation of structures and patterns in the artificial catchment. Initial structures formed by the construction process and initial substrate characteristics were decisive for the distribution and flow of water. External factors like episodic events triggered erosion and dissection during this initial phase, promoted by the low vegetation cover and the unconsolidated sandy substrate. The transformation of the initial geo-system into areas with evolving terrestrial or aquatic characteristics and from a very episodic to a more permanent stream network and discharge, together with the observed vegetation dynamics increased site diversity and heterogeneity with respect to water and nutrient availability and transformation processes compared to the more homogenous conditions at point zero. The processes and feedback mechanisms in the initial development of a new landscape may deviate in rates, intensity and dominance from those known from mature ecosystems. It is therefore crucial to understand these early phases of ecosystem development and to disentangle the increasingly complex interactions between the evolving terrestrial and aquatic, biotic and abiotic compartments of the system. Artificially created catchments could be a suitable tool to study these initial developments at the landscape scale under known, designed and defined boundary conditions.}, language = {en} } @inproceedings{SchaafBiemeltFischeretal., author = {Schaaf, Wolfgang and Biemelt, Detlef and Fischer, Anton and Gerwin, Werner}, title = {Chicken Creek after five years: what changed?}, series = {EGU General Assembly 2011, Vienna, Austria, 03 - 08 April 2011}, booktitle = {EGU General Assembly 2011, Vienna, Austria, 03 - 08 April 2011}, language = {en} } @inproceedings{GerwinSchaafHuettl, author = {Gerwin, Werner and Schaaf, Wolfgang and H{\"u}ttl, Reinhard F.}, title = {The artificial catchment 'Chicken Creek' ('Huehnerwasser') as a new research tool for hydrological and ecological studies}, series = {EGU General Assembly 2009, Vienna, Austria, 19 - 24 April 2009}, booktitle = {EGU General Assembly 2009, Vienna, Austria, 19 - 24 April 2009}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, language = {en} } @inproceedings{SchaafGerwinBiemeltetal., author = {Schaaf, Wolfgang and Gerwin, Werner and Biemelt, Detlef and Fischer, Anton}, title = {Monitoring of initial patterns and structures in an artificial catchment}, series = {EGU General Assembly 2010, held in Vienna, Austria, 02 - 07 May 2010}, booktitle = {EGU General Assembly 2010, held in Vienna, Austria, 02 - 07 May 2010}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, language = {en} } @incollection{ElmerBiemeltGerwinetal., author = {Elmer, Michael and Biemelt, Detlef and Gerwin, Werner and Hoberg, Karin and Kleeberg, Andreas and Lessmann, Dieter and Schaaf, Wolfgang and Schneider, Anna and Zaplata, Markus K. and H{\"u}ttl, Reinhard F.}, title = {Conclusions}, series = {The artificial catchment Chicken Creek - initial ecosystem development 2005-2010}, booktitle = {The artificial catchment Chicken Creek - initial ecosystem development 2005-2010}, editor = {Elmer, Michael and Schaaf, Wolfgang and Biemelt, Detlef and Gerwin, Werner and H{\"u}ttl, Reinhard F.}, publisher = {FZLB}, address = {Cottbus}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:co1-opus-23730}, pages = {145 -- 153}, language = {en} } @misc{SeiffertNenovMaureretal., author = {Seiffert, Thomas and Nenov, Rossen and Maurer, Thomas and Gerwin, Werner and Veste, Maik and Raab, Thomas}, title = {Microdrone-based photogrammetry for water catchment monitoring}, series = {Dimensions of ecology - from global change to molecular ecology, (Gf{\"O}) 39th annual conference, University of Bayreuth, 14th - 18th September 2009}, journal = {Dimensions of ecology - from global change to molecular ecology, (Gf{\"O}) 39th annual conference, University of Bayreuth, 14th - 18th September 2009}, editor = {Holzheu, Stefan and Thies, B.}, publisher = {Bayreuther Zentrum f{\"u}r {\"O}kologie und Umweltforschung (BayCEER) Selbstverlag}, address = {Bayreuth}, pages = {S. 129}, language = {en} } @misc{KiourtsisKeramitzisPapatheodorouetal., author = {Kiourtsis, Fotios and Keramitzis, Dimitrios and Papatheodorou, Ioannis and Tsoulakaki, Dimitria and Gontzaridou, Marina and Lampetsou, Eugenia and Fragkiskakis, Nikitas and Gerwin, Werner and Repmann, Frank and Baumgarten, Wibke}, title = {Marginal sites in for biomass production - case study sites in northern Greece : obstacles and solutions}, series = {European Geosciences Union General Assembly 2017 Vienna, Austria, 23-28 April 2017}, journal = {European Geosciences Union General Assembly 2017 Vienna, Austria, 23-28 April 2017}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, abstract = {In 2016, D.A.M.T, the Hellenic Forest Service for northern Greece (Macedonia and Thrace Regions), with the support of BTU Cottbus-Senftenberg Reseach Center Landscape Development and Mining Landscapes experts and following common standard protocols of the SEEMLA project, established three plots, in the northeastern part of Greece, in Rodopi prefecture (main forest species for biomass production: Pinus Nigra, Pinus Brutia and Robinia Pseudacacia). Nearby productive ecosystems (including forests etc.) or successional sites will be used as references for estimating the potentials of MagL. Further existing plantations of energy crops on similar MagL, will be used to assess potential crop yields. These plots represent different types of marginal lands, they were specifically selected for SEEMLA purposes (reliable and sustainable exploitation of biomass) and are entirely different from other inventories, used for typical forest operations in Greece. The main differences are: - an intensively studied core area, - Soil Quality Rating (SQR) method measurements, - Soil Classification Maps - parameters estimation (land capability classes and landforms), - tightly spaced plantations (1,5 m x 1,5 m), - cropping systems, - shorter rotations and - the need for special forest management study. The combination of these requirements with the soil conditions of the area has created significant issues on plots establishment and accurate recording of supply chain stages. Main expected SEEMLA impacts are: • provide a substantial amount of EU energy needs from marginal/degraded land, • avoidance of land use conflicts by strengthening the ability to use MagL for biomass production for energy, • reduction of EU-wide greenhouse gas, • mitigation of conflicts regarding sustainability and biodiversity for the utilization of MagL for biomass production, • growth of plantations of bioenergy carriers from MagL at competitive costs, • expansion of economic opportunities for farmers, foresters and rural regions in general through biomass production on MagL and related processing activities, • investments in new technologies and the design of new policy measures.}, language = {en} }
