Reconstruction with drones, plan to save colas in Australia – environment – life

Plant tree seeds with drones Australia, Whose forests were burned by the devastating wildfires of 2019-20, which are part of a pilot project that is set to begin to reclaim habitats Colas Save it from destruction.

‘S plan Global Fund for Nature (WWF Australia), Stuart Blanche, the restoration manager of the voluntary charity, explained that the plan is to plant 100,000 trees in three years, starting with a drone launch next April or May, when the rains end this summer due to the La Nina event.

The drones could drop a maximum of 40,000 seeds a day, which, if successful, could open the door to the WWF Australia’s ambitious plan to plant and preserve 2 billion trees by 2030.

The WWF is still exploring whether recycling using multi-seed capsules mixed with artificial soil and compost, or launching them en masse on different surfaces, is tilting and inaccessible, weighing both cost and germination opportunities.

“We want to see if drones are better at reclaiming cola habitats. In the future, if they all work, we can spread millions of seeds across eastern Australia to help recover from fire and drought. But first we need to show that they work,” Blanch said.

Massive damage

Australia’s reconstruction dream was severely affected by what is known as the ‘Black Summer’ fire of 2019-20, which killed 34 people and burned more than 5,000 buildings and 186,000 square kilometers of land, an area similar to Syria and 70 per cent of which is forest.

The fire, considered one of the longest and most devastating in Australia, burned or damaged about 7 billion trees and killed 3 billion animals, including 60,000 koalas, or injured or left homeless after fleeing from them.

One year before the disaster, the WWF had already warned that deforestation would cause colas to disappear in the state of New South Wales before 2050, which is considered vulnerable to the neighboring state of Queensland.

Paradoxically, New South Wales and Queensland “have the best chance of preserving colas because they have good genetic diversity,” Blanche said.

Against the clock

To save them, the WWF is fighting against time to not only plant trees, but also to check that they are growing enough to create safe corridors in the habitats of these marsupials that have been ravaged by fire.

Also, a WWF Australia representative explained that a eucalyptus “should be about 37 centimeters in diameter, which means it’s probably 20 or 30 years old, to become the best habitat for a cola.”

But Blanche believes he did not wait that long when he saw “colas in trees about five meters tall and about two or three years old,” however, “this is not ideal habitat because they are not tall.” ”

According to a WWF expert, it would be best if forests in Australia were allowed to regenerate naturally and the destruction of cola habitats would be stopped by laws and an end to deforestation. Activities, incentives for farmers to designate security areas.

Blanche also argued for the improvement of traditional tribal practices, which include the creation of controlled and low-intensity fires in forests that are not affected by fires because “eucalyptus seeds often germinate after a fire.”
