So Shoot Me

Should non-native species classify as a kind of biodiversity?  The answer, one would think, is straightforward and should be uncontroversial. We need look only to the international Convention on Biological Diversity to find it. And the definition there is clear: biological diversity (or ‘biodiversity’) is defined as: ‘the variability among living organisms from all sources including, inter alia, terrestrial, … Read More

Introduced species can cause significant changes in their receiving environments. For any new species, a wide range of effects can be contemplated – both positive and negative. In the absence of evidence, caution is surely needed. Introduced by accident in the mid-1960s, ‘plague skinks’ (Lampropholis delicata) have been known for all but about the last eight years as ‘rainbow … Read More

Answer: It’s not clear. Ambiguity over target species is counterproductive, both to the goal itself, and to the public’s ability to understand and monitor progress towards it. On 26 July 2016 the then National Government announced a plan to eradicate all of New Zealand’s rats, stoats and possums by 2050. The decision – including the species to be … Read More

It’s a New Year, and with it, time for a confession: my blogging output has been pretty bad. The good news is I’ve found a solution. Since joining the Sciblogs stable in March 2017 I’ve written a total of 17 posts. That’s less than one a month. And, in truth, it’s even worse than that because fully 13 of them … Read More

I wanted to end now on a couple of final reflections and thoughts. First, I implore you as the next generation of ecologists to think critically about the assumptions of your disciplines. Don’t just blindly swallow the positions of your older colleagues, including me (OK, not so much me…). Restoration Ecology, in particular, was developed and propagated mostly by … Read More

Some final comments from my interview with Kim Hill:  ‘It’s a very defeatist way of looking at things, and I don’t buy it!’ ‘Please make him stop! He’s such a defeatist!’ ‘So, the answer is don’t care? Do whatever?!’  A lot of people who advocate for novel ecosystems and new approaches in ecology and our understandings of nature … Read More

This is this idea that we either do this or something that we love dies – what might be referred to as ‘conservation at the barrel of a gun’. Here’s another collection of quotes from the feedback to Kim Hill again – the last one most notably being from one of New Zealand’s foremost conservation biologists: ‘By accepting many introduced … Read More

Here are more comments from my interview with Kim Hill: ‘…each species we lose puts the entire ecosystem at risk of collapse’  ‘Without the species that are adapted to these native environments a whole ecosystem will eventually collapse’ Some people say that our ecosystems are going to collapse under the weight of introductions, that our ecosystems are essentially going … Read More

Here are more comments from my interview with Kim Hill: ‘…we do not have to accept a future that sees our ecosystems as homogeneous with everything else, comprised of international tramp species and the few natives that can persist with them’ ‘…there’s a tonne of [introduced] plants out there that if we let go they’ll change landscapes and there’ll be … Read More

Many people have this idea that we just need to trust the scientists on this one. Science will tell us what to value so we should just leave it to them. Here are some comments again from my interview with Kim Hill: ‘This is not a cultural judgment about the value of different species but is a scientific one’ … Read More
