On a recent tour of Eve’s Pond with a community group we all saw something poke its head out of the water. One young woman thought it was a turtle. I didn’t want to believe her but there it was: the dreaded Red-eared Slider. Someone’s pet got too big for its terrarium and was left at Eve’s Pond for us to foster.
Last month, someone dumped water hyacinths in the ponds at Spittal Pond. These exquisitely beautiful plants are killers: they reduce oxygen levels for fish, creating conditions conducive to mosquito proliferation. They make water murky and reduce biodiversity.
They are wiping out our mosquito-larvae-eating killifish and gambusia. This is directly causing a serious mosquito problem. In turn, this requires increased use of chemicals in the atmosphere and on our bodies to deal with the problem we unnecessarily caused ourselves!
And consider the chickens. Some years ago, someone released chickens they no longer wanted. Now we have tens of thousands of chickens roaming freely around our island, damaging farmers’ crops and home vegetable patches and irritating us with early morning roosters crowing.
Those who dump their unwanted pets and plants in our natural areas probably mean no harm. But we need to educate ourselves. Putting something where it doesn’t belong is a problem for us all. And it is costing us a fortune. Invasive species are defined as: non-native species whose introduction is likely to cause economic or environmental harm or harm to human, animal or plant health.
How do they affect us economically?
In Bermuda we invest an immense amount to get rid of invasive species; you’ve heard it again and again. It requires human resources, time, equipment, not to mention the cost of gas to transport horticultural waste to the dump (at $50+ per load). All this could be spent on efforts to make our island more beautiful, more biodiverse and healthier. But the constant, unrelenting distraction of clearing invasives leaves little time for anything else.
It is literally affecting our cost of living.
Check these numbers out: Studies have shown that in the 1960s invasive species cost the US approximately $2 billion annually (about $6 per person). Recent data suggests invasive species cost the US about $120 billion a year (about $370 per person) in economic and environmental damage. On a global scale invasive species are said to cost the world more than $1.28 trillion dollars (almost $200 dollars for every person on the planet) at a low estimate.
Those individuals who don’t give much thought to the damage to our beautiful, unique environment and ecosystems might be a bit horrified at the waste of money.
The Protected Species Act 2003 recognizes the willful destruction, damage, removal, or obstruction of a habitat as an offence and offenders are liable to fines as great as $25,000 for ongoing offences. I’m not sure anyone has ever been found guilty, and rather than focus on a punitive approach, I’m hoping we can work together to make sure everyone is knowledgeable about the impact invasive species are having on our community, as I’m sure nobody has time or money to invest in something so potentially destructive.
