Southern Bent-Wing Bat, Invasive Species and Competition - Coggle Diagram
Southern Bent-Wing Bat
Habitat Loss and Fragmentation
Land Use Change
Agricultural Expansion
runoff contaminates wetlands and cave catchments
Tourism development
too many cave exploration
Urbanisation & infrastructure
Road Fragment flight paths
Light and Noise pollution for development
Deforestation
clearing native vegetation leading to loss of foraging habitat
Cave Disturbance
Vandalism or lighting
Mining and quarrying destroys caves
causes vibration and dust that disturb rooting bats
Human interference
human entry during breeding/rooting seasons
Environmental Degradation
Pesticides and insect decline
Water pollution
Climate change
Sea-level rise
forces bats to relocate, increasing stress and mortality risk
reduces availabile dry roosting space for maternity colonies
Agriculture and Pesticides
insect decline from insecticides, less prey
Monoculture reduces biodiversity
Current Measures
Climatic change & Hydrology
Altered rainfall reduces insect emergency
temperature/humidity shifts in caves after breeding
Pollution and water quality
Agricultureal runoff leading to degraded wetlands
groundwater extraction lowering water tables near caves
Habitat Fragmentation
loss of vegetation corridors between roots and foraging areas.
Secondary effects
Lower reproductive success and colony declines
local extinction from small, isolated populations
Reduce resilience t stochastic events
Conservation responses:
restore vegetation corridors or rewilding strips
Buffer zones around caves, restrict access to breeding season
Reduce pesticide use; promote IPM on farms
Artificial Roots and sheltered corridors (biomimicry)
Community stewardship & light-reduction programs
Climatic Change and Extreme Weather
Bushfire
Echolocation Disruption
Inability to Feed
Tree Loss
Less Foraging Habitat
Change in Insect Population
Smoke in Key Roosting Caves
Major Loss of Concentrated Population
Prolonged Severe Drought
Loss of Natural Vegetation Density
Reduction in Foraging Resources
Drying Climate
Loss of Native Forest
Dwindling Fresh Water
Reduced prey availability
Loss of Wetlands
Rising Median Temperatures
Hotter Caves
Interrupts Breeding Patterns
Reduced Humidity in Caves
Higher Pup Mortality
Increased Presence of Pathogens
