Workshop on Landscape History
Sopron, 22 April 2010
Objectives
• Description of investigation area
• Methodology, outputs• Preliminary results of the
project
TransEcoNet project regions
3-country Nature Park: Goričko – Raab – Őrség• 1996 – Raab • 2002 – Őrség• 2003 – Goričko
Associated initiatives(local, cross border,transboundary)• Slovenia:
– Biomura• Hungary:
– National Park Őrség• Austria:
– Nature Park Raab• Europe:
– Natura 2000– Greenbelt
Southern region
Slovenian part: Pomurje
• the activities are carried out in the Pomurje region, Slovenia– the spread of the invasive species Robinia pseudacacia– the underlying causes and assess landscape scale ecological
dynamics (e.g. Mura River floodplains, land use analysis in time series of last 200 years) in ecological networks
– the concept of place attachment and identification of the people with their landscape
• partners for the Pomurje– PP14: University of Nova Gorica (UNG)– PP15: Regional Development Agency Mura (RRA)– AP20: Nature Park Goričko– AP21: Scientific Research Centre of the Slovenian Academy of
Sciences and Arts (ZRC SAZU)
Pomurje, Slovenia
Forests and natural heritage of
Mura River
Methodology, outputs
Methodology, outputs• WP4
– multi-scale mapping of the history– comparison with the current status of
ecological networks in Central Europe– [Historical datasets of Mura River: (1) maps,
plans, orthophotos, satellite images, (2) other material: photographs, topographic reports, tales/myths… (3) Methods: GIS, RS and statistic analysis, empirical approaches, multi-scale and multi-quality data analysis]
Preliminary results of the project
Preliminary results of the project
• identification and mapping of the Robinia pseudacacia
• historical maps (spatial data sets) of Pomurje region for various applications
• land use changes analysis (time series: landscape reconstruction for the last 200 years)
• cooperation, harmonisation, other PPs
Riparian forest of River Mura
On the bank of the river grow floodplain forests, as • Salicetum albae• Fraxino-Ulmetum• Genisto-Quercetum• neophytic tree species Robinia pseudacacia
Fraxino-Ulmetum
Salicetum albae
Genisto elatae-Quercetum roboris
• Robinia pseudacacia (= tree)– native from Pennsylvania to northern
Georgia and westward as far as Arkansas and Oklahoma
– introduced to Europe at the beginning of the 17th cent.
– flowers: early May, after the leaves• it occurs on meadows and agricultural
surfaces that are being overgrown– it is invasive in mild climate as in the
Pomurje region is (= natural expanding + plantation)
– most expanded in the region in 1980s– affect of socioeconomic situation in the
region (?)• the vegetation in these regions has
changed to such an extent that it cannot be classified into any forest community
Robinia pseudacacia
Some criteria for recognition of the species:• white flowers in spring (after leaves)• lighter green colour comparing with floodplain forest…Data sources:• sat. images: IRS-P6 (Indian Remote Sensing ~5 to 20 m),
Landsat ETM and TM (30 m)– from 1990s to today; lower spatial, higher spectral resol.
• contemporary orthophotos and aerial photographs starting from 1959• IR-orthophotos• contemporary (and historical) maps, plans• DEM/DTM (+ LiDAR)• field work mapping, various land use data, Corine Land Cover, soil map…• interviews with local farmersMethodology (RS, GIS and statistic techniques):• reconstruction of R. pseudacacia-dynamics in the recent decade• modelling the distribution of R. pseudacacia in relation to abiotic environmental
factors and land use• modelling (prediction) the expected distribution of R. pseudacacia in case of climate
and land use change
Identification and mapping of the Robinia pseudacacia
Historical maps (spatial data sets) of Pomurje region for
various applications
Outputs:
- land use spatial data sets
- study of Mura River changes (natural and anthropogenic)
Data sets:
- historical maps + LiDAR DTM + other documentation
Mura: Habsburg1st military survey (Josephine)
1763–1787; 1 : 28 800
commissioned by the empress Maria Theresa
cause: Seven Years’ War against Prussia (1756–1763)
no projection (maybe Cassini-Soldner), no coordinates
that time exceptionality achievement
graphical mapping – considerable deformations

(1 : 1440)
Habsburg2nd military survey (Franciscan)
survey: 1817–1825, mapping: 1830–1834 1 : 28 800
applying trigonometric points for survey
quality influence of producing of Franciscian cadastre 1823–1826
3 coordinate systems in Slovenia (+ 3 canters of geodetic surveys - datums):
Krim (near o Ljubljana)
Schöckl (near to Graz)
Gellért (near to Budapest)

Habsburg (Austro-Hungarian Monarchy)
3rd military survey
1869–1887; “special” 1 : 75 000; optional: 1 : 25 000 (survey was in this scale) and “degree” maps (“general”) 1 : 200 000
horizontal and vertical network according to Mittel-Europäische Gradmessung
