Saudi Arabia's King Abdulaziz Royal Reserve Development Authority, in cooperation with the National Center for Vegetation Cover and Combating Desertification (NCVC), has completed the planting of one million trees in Rawdat Al-Khafs, located south of the reserve.

The first phase of planting 500,000 trees in the northern and southern parts of Rawdat Al-Khafs was completed in August 2022 and the remaining 500,000 trees were planted in 2023.

Through this initiative, the authority seeks to support national efforts to realize the objectives of the Saudi Green Initiative by increasing vegetation cover, combating desertification and preserving natural resources to achieve sustainable environmental and economic development and improve the quality of life.

The planting of the trees in the reserve comes within the agreement signed between the authority and NCVC on the sidelines of the International Exhibition and Forum on Afforestation Techniques in May 2022.

The King Abdulaziz Royal Reserve is one of the seven royal reserves in Saudi Arabia. It is known for its broad geographical scope, which includes Al-Tanhat, Al-Khafs, and Noura parks, and parts of the Al-Summan plateau and the Al-Dahna desert, covering approximately 28,000 sq. km.

A new carnivorous caterpillar that wears the remains of its prey has been dubbed the “bone collector.”
The odd insect is only found on the Hawaiian island of Oahu. It creeps along spiderwebs, feeding on trapped insects and decorating its silk case with their body parts, The Associated Press reported.
There are other meat-eating caterpillars that “do lots of crazy things, but this takes the cake,” said study author Dan Rubinoff with the University of Hawaii at Manoa.
Scientists think the case might act as camouflage, allowing the caterpillar to feast on the spider’s ensnared meals without getting caught.
A host of caterpillars native to Hawaii use silk glands to spin protective cases studded with lichen, sand and other materials. This one is the first to use ant heads and fly wings.
“It really is an astonishing type of case,” said Steven Montgomery, an entomology consultant in Hawaii who was not involved with the new study.
Findings were published Thursday in the journal Science. Scientists found just 62 of the carnivorous caterpillars in over 20 years of observing.
Predatory caterpillars are extremely rare and the bone collectors found in Hawaii will even eat each other, researchers said.
The bone collector's origins date back at least 6 million years, making the caterpillars more ancient than the Hawaiian islands themselves. Today, they dwell on an isolated patch of mountain forest alongside invasive species.
“There is really a concern that we need to do better with conservation,” said Rubinoff.
