HONG KONG — “Spiderman … Tom Holland,” two secondary school boys repeated to each other as they watched conservationist Harry Wong nimbly climb a tall tree at their school, St. Louis School, in downtown Hong Kong. On a humid September afternoon, Wong installed a nest box for yellow-crested cockatoos (Cacatua sulphurea) on a candlenut tree (Aleurites moluccanus). Equipped with a harness and ropes, he climbed up the tree, installed the box, and quickly rappelled down. Wong and Astrid Andersson, a biologist and postdoctoral researcher at the University of Hong Kong (HKU), are the dynamic duo behind HK Cockatoo Watch, a conservation project that seeks to protect the city’s feral yellow-crested cockatoos.

Yellow-crested cockatoos are considered to be critically endangered, with fewer than 2,000 individuals remaining in their native range in eastern Indonesia and Timor-Leste. However, few people know that Hong Kong is home to the largest wild population of the species outside the two Southeast Asian countries. There are roughly 200 cockatoos in the city, or about 10% of the global wild population, believed to be descendants of released or escaped pets. The number is stable, thanks to the lack of natural predators and strict legal protection. A recent DNA analysis study by Andersson and her research team found that Hong Kong’s feral cockatoos have unexpectedly high genetic diversity and…This article was originally published on Mongabay

Indonesia’s government is imposing new restrictions on access to geospatial data, raising concerns among researchers and activists that it will suppress environmental science and advocacy work in one of the world’s most biodiverse countries. For around a month, visitors to an interactive mapping platform maintained by the Ministry of Forestry have been greeted with a pop-up legal notice warning that the information is “view-only” and that anyone who “downloads” or “extracts” it without the ministry’s written permission “will be prosecuted” under the 2008 Electronic Information and Transactions, or ITE, Law. Anyone who wants to use the once freely accessible platform, known as SIGAP, must first agree to “terms and conditions” stating that the relevant articles in the ITE Law “carry penalties of up to 9 years in prison and/or a fine of up to Rp 3 billion [$170,000],” the notice says. On Sept. 21, the ministry’s Directorate General of Forestry Planning posted a video to Instagram outlining a new application process that requires prospective users to disclose their research aims and submit supporting documents. Doni Prabowo, the department’s head of forest monitoring and geospatial information, told Mongabay that restrictions were needed because geospatial data had been uncontrolled for a long time, creating opportunities for manipulation and illegal trading of the country’s precious information. “What if somebody manipulates the data and says certain areas are not protected forest [when they really are]? It could be dangerous,” Doni said by phone. He said he’d heard of the ministry’s geospatial data being listed…This article was originally published on Mongabay
