Landscaping works contributing to further biodiversity loss
A few decades ago, butterflies of every shape and colour would take off in swarms as you walked under carob trees. Nowadays, the decline of butterflies is occurring at such a high rate that when naturalists spot a particularly uncommon species, they do not disclose its location; to protect the insects from harm.
While migratory butterflies can still be spotted with some frequency, local butterflies have all but disappeared from view. Landscaping works being carried out without consideration for local fauna and flora are having a devastating effect of the state of Maltese biodiversity, according to experts.
Jake Farrugia, an earth systems student and amateur lepidopterist, recounts how just earlier this month, while collecting fennel for his own larvae, he spotted a large number of swallowtail butterfly larvae nestled in the fennel bushes. Returning to the site a few days later, Mr Farrugia says that during landscaping works in Triq il-Buskett, Rabat, the native fennel bushes on the side of the road were all removed, taking the butterfly larvae with them.
“Plants growing under country walls and other walls are essential in providing micro habitats for all sorts of flora and fauna,” Mr Farrugia says.
“A butterfly looking to deposit eggs, such as the swallowtail, would have gladly chosen this spot since it is sheltered from the sun and wind as well as potential predators.”
The removal of fennel bushes and other local flora constitutes as habitat loss… We are shooting ourselves in the foot,” Mr Farrugia says, adding that the desire to ’embellish’ public spaces is not allowing nature to adapt .
Alfred Baldacchino, an environmentalist and former assistant director at the Mepa Environmental Directorate, describes the conservation of biodiversity as pitiful. ,
“Despite the fact that the Environment and Resources Authority is responsible for biodiversity protection and conservation through the enforcement of EU legislation, they are incompetent, ignorant of the situation and failing to take any proactive measures,” Mr Baldacchino says.
Biodiversity loss can be attributed to an intersecting number of external situations, the most pressing of which, according to Mr Baldacchino, is climate change. Rapid changes in temperature, the use of fossil fuels and pesticides are compounded upon flora and fauna, giving the environment very little time to adjust.
“ERA is incompetent and ignorant of the situation”
“This year alone we have seen temperatures in France soar to 45’C, several fires in Europe, the destruction of Miżieb,” says Mr Baldacchino.
“There is a complete lack of interest, lack of tangible effort, lack of any help at all from the Ministry responsible for climate change and the environment.”
According to Mr Baldacchino, the ERA and Ambjent Malta are not doing enough to mitigate the effects of climate change and prevent further biodiversity loss through adequate conservation plans.
“Mizieb is a case in point,” he says,”first there’s a disaster and afterwards we run a study about how it could have been prevented.”
When it comes to landscaping, Mr Baldacchino says the authorities and entities concerned demonstrate a pattern of disinterest and wilful ignorance with respect the havoc being wreaked on native flora.
“The Environmental Landscapes Consortium is the worst enemy of biodiversity,” Mr Baldacchino says. “Their only interest is.monetary profit. Despite the fact that they have been paid €8 million a year for the past 15 years from public funds, all they have to show for it is the destruction of biodiversity, use of chemicals and water-thirsty turfs which compete with local flora.”
There is a public perception of biodiversity that regards the majority of wayside flora as ‘ħaxix ħażin’ (weeds) and that its removal causes only superficial damage. This position is something Mr Baldacchino calls “professional ignorance” as even school children are taught that flora is an integral part of the ecosystem.
Wayside flora are unique ecological niches and often serve as breeding grounds for insects and other fauna, as well as being highly attractive to pollinators, such as bees and even butterflies.
The careless removal of these niches could spell doom not just for our butterflies but for the long term health of the environment itself, Mr Baldacchino stresses.
“When ELC act like they derive pleasure from removing every blade of grass that grows, we only have a recipe for disaster.”
