Depending on which side of the fence you sit, cacti, in all its various forms, are either loved or loathed as ornamental delights or prickly pests that can devastate ecosystems, wildlife, and livelihoods.
The issue was in the spotlight recently when an article published on the BBC News Science & Environment website ‘Prickly cactus species ‘under threat’ brought the issue of the cacti’s plight in sharp focus.
Whether trying to cajole one out of your office or running for cover after it seems a little too interested in your food we have likely all encountered the common wasp (Vespula vulgaris) more than once during this particularly wasp-heavy summer. But did you know that this is just one of 9000 species of wasp found in the UK and without a microscope you’re unlikely to ever see the vast majority of them. You might also not know that they provide us with great ecological services including pollination of both our crops and wildflowers as well as controlling insect populations which spread human and agricultural diseases.
At first sight the humble scale insect, Orthezia insignis doesn’t seem like it could pack much of a punch in a ‘fight’ against a range of native flora – but to make such an assumption would be very dangerous indeed.
In fact Orthezia insignis is a genuine invasive menace which in Hawaii, East Africa and South and Central America has, at times, wreaked havoc on numerous ornamental plants including citrus, coffee, olive, Jacaranda and Lantana.
CABI scientists have penned an important paper published in the journal Biocontrol Science and Technology which pulls no punches when it boldly states ‘the future of humankind and the rest of Earth’s biodiversity depend upon our research efforts generating solutions to the global challenges.’
National meadows day is an annual awareness event focussed around the first Saturday of July, but up and down the country activities took over the whole weekend. Traditionally managed British meadows are characterised by low soil fertility and actively managed cutting or grazing, supporting a range of colourful flowering species including the oxeye daisies seen in the picture above. These species rich meadows, which used to cover much of England’s countryside, were traditionally generated by farmers managing for hay and pasture. Ironically these important habitats have now largely been eradicated by modern agriculture. In recognition of this fact there are now numerous conservation projects and financial incentives in place to encourage the maintenance and regeneration of British Meadows. But with so many environmental schemes and species vying for position in British conservation why are meadows so important and how can agriculture help? Continue reading →
World Environment Day, held annually on 5th June, is considered to be the UN’s most important day for promoting global awareness and action to protect the environment. This year’s theme is one that shines a spotlight on what has become a particularly hot topic over the last year – plastic pollution. Coincidentally, it was also the theme of this year’s Earth Day and will be the focus of World Oceans Day on June 8 and all for good reason.
