Transcript of Use of GIS for amphibian habitats monitoring in southern ... · Variety of characteristics ....
Situation – „we need to protect animals and find their habitats”
Problem – „where can we find them?”
Traditional approach – „go to the field to find them”!
Goal - „start your computer to find them”
Location
Located in the
southern part of
Poland
Area of the forest
district - 22 139 ha
Lots of swamp
forests
Many rare animal
species present
Materials
Quantum GIS ver.1.7.4
Garmin 62s GPS
Forest Numerical Map layers
Permissions from the Regional
Environmental Directorate
Field equipment
Locating the ponds
Observation
Field work &
information gathering
Mapping
Data analysis
GIS & data analysis
Methods
Methods – locating the ponds
9 sites so far
Ponds were selected based on previous
research
Variety of characteristics
Methods - observation
Observations of adult amphibians
Singing recognition
Regular surveys
Gathering location characteristics
Methods – mapping & data analysis
Marking ponds with the GPS receiver
Displaying the data
Correlation between pond features and
existing data
Significance of factors (site type, size,
proximity to roads, exposition, water
plants, impact from predators)
Cross reference with NATURA2000 data
