AIM: Stochastic population models assess the population viability of three contrasting Litoria raniformis populations under different harvest strategies. Harvesting strategies are: harvest as eggs, larvae or adults, and at collection proportions from 0 - 100% in 5% increments.

Repository includes the following files:

• 'matrixOperators.R' — functions to manipulate matrix models
• 'Sustainable_Harvest_Lraniformis_V14.R' — R #code to run all population models and create display items.
• 'Sustainable Harvest GSA V14.R' — R #code to run a global sensitivity analysis of the sustainable harvest model.
• 'startPopsEpsom2.csv' — 10000 burnt-in starting population for the Bendigo Water Reclamation Plant.
• 'startPopsNapNap2.csv' — 10000 burnt-in starting population for Nap Nap wetland.
• 'startPopsHogwash2.csv' — 10000 burnt-in starting population for Hogwash Bend central basin.
• 'wetdryEpsom.csv' — 10000 simulated hydrological centuries expressed as 'wet' and 'dry' sequences. wet = breeding, dry = no breeding. For the Bendigo Water Reclamation Plant models.
• 'wetdryNapNap.csv' — 10000 simulated hydrological centuries expressed as 'wet' and 'dry' sequences. wet = breeding, dry = no breeding. For the Nap Nap wetland models.
• 'wetdryHogwash.csv' — 10000 simulated hydrological centuries expressed as 'wet' and 'dry' sequences. wet = breeding, dry = no breeding. For the Hogwash Bend central basin models.
