Design a portable, lightweight, weather-proof, durable, effective implement for tracking the presence of rodents for an outdoor setting. We will test it at school, then try to use it in then bush. Perhaps we could set some up in patches of native bush around Hamilton...? [Is there a suitable one nearby?]
Why do we need something like this? Well, since we know rats and mice are pests in the NZ bush ecosystem, we need to be able to reliably work out whether or not they are present if we are to reintroduce endangered native species.
What other creatures might we want to check for? Any ideas for tracking stations for those animals? Think about their ecological niches and how you would best test for their presence.
i.e. Would you test for things that eat native fish up trees?
