Trees to the fore
The Arbor Day tradition continues strongly in New Zealand. Carterton Farmers’ Market hosts their annual Arbor Sale on Sunday, May 28, under the verandah opposite Memorial Square, from 9am to 12.30pm. Trees, shrubs, natives, fruit trees, and winter crops for the vege garden will feature. Those wishing to sell plants, trees, and excess harvest produce should contact [email protected] or 027 663 9011.
The first Arbor Day was held in Greytown 133 years ago, promoted by William Nation, Wairarapa Standard proprietor.
The first planting by Greytown school children took place on July 3, 1890.
Help for kelp
Climate scientists are now restoring kelp forests under siege from climate change, pollution, and human interference.
Kelp forests are havens for diverse marine species, from fish and invertebrates to marine mammals. They also act as carbon sinks, absorbing and storing copious amounts of carbon dioxide from the atmosphere and ocean. As well, kelp forests benefit coastal communities in various ways.
Projects include active restoration and deliberately planting kelp or kelp fragments in degraded areas to jumpstart their recovery. Kelp farming ensures a steady supply of kelp for various applications, ranging from food and biofuel to bioplastics. Reintroducing key predators, such as sea otters, helps control sea urchin populations and prevents the overgrazing of kelp.
Trees to
the rescue
Barcelona in Spain has implemented its 2017 – 2037 Master Plan for Trees. By 2037, the city will increase the overall tree cover by 5 per cent, covering 30 per cent of the city’s surface area. This increase in urban tree cover is likely to improve the health of more than 30 000 people, reduce the use of antidepressants and save over $40 million annually in mental health costs.
