The Royal Parks in London are urging people to stop feeding bread to wild birds like swans and ducks. Human feeding is causing overcrowding and bullying among birds and leads to stress and disease spreading. Bread is not natural food for wild birds and doesn’t provide important vitamins for them; leftover bread also attracts rats and contaminates the water as well.
巴西聖保羅州西部的 Great Pontal Reserve， 原本擁有非常獨特及瀕危的季節性半落葉森林，但1940於年代後期，大量人類遷居開發導致八成森林消失。科學家在研究極危的黑獅面狨時發現牠們受森林破碎所威脅，於是希望想辦法改善情況。他們與當地社區合作，培養樹苗及植樹。經過35年的努力，他們已種植了超過 270 萬棵樹木，覆蓋了 6000 公頃的森林。這復修不但改善了黑獅面狨的棲息環境，住在那𥚃的美洲獅及貘等亦同樣受惠。
The Great Pontal Reserve is located at the west of the state of São Paulo, Brazil. It contains seasonal, semi-deciduous forest which is an unique and endangered type of forest. Human civilization destroyed 80% of the forest in late 1940s. When studying the endangered black lion tamarins, scientists found out that fragmentation of forests was the main threat to these rare monkeys and decided to improve the forest connectivity. They involved the local communities to plant trees starting from seeding nursery. Over the past 35 years, they planted more than 2.7million trees that covers 6000 hectares of forest. The improvements not only helped the endangered tamarins, but also other wildlife inhabit there like pumas and tapirs.
Around 3000 years ago, Tasmanian devils disappeared completely on mainland Australia because of introduced dingoes. 26 Tasmanian devils were reintroduced to a wild sanctuary on mainland, and recently there seven joeys were born and they were the first births there in 3000years!
traditionally in chicken farms, male chicks are slaughtered shortly after hatching because they cannot lay eggs and are not suitable for meat production. Germany will ban the mass slaughter of male chicks starting next year because it is unethical. Famers will be required to use technology to check the sex of eggs and get rid of male eggs before hatching.
A recent research found that exotic plants that critically endangered Christmas Island flying foxes feed on have less nutritional value and do not provide them a balanced meal. researchers worry this would further threaten the survival of flying foxes and the local ecosystem, as they are important pollinators and seed dispersers on the island.
porcupines are being illegally hunted for meat and medicine in Indonesia. their meat are usually consumed; their spines are for decorative purposes and their bezoars are traditionally used to cure poisoning, typhoid and cancer in south east Asia. there are five species of porcupines in Indonesia. Their population is declining due to habitat loss and illegal poaching.
Weirs were built on the Severn Rivers in UK for transportations; many fishes like salmons and eels were unable to migrate back for spawning from the ocean for over 170 years. Recent years, there are plans to create routes around four major weirs, and two of them are completed recently; the team is hoping to see the return of the twaite shad, traditionally known as the May fish, this May.
There only fewer than 100 of critically endangered Sumatran rhinos, and they are mainly threatened by poaching, habitat loss and fragmentation. Research found they retain higher genetic diversity as expected, means they are more likely to survive threats like climate change or disease. However, with small population size they show low levels of inbreeding. This worries the researchers because another subpopulation showed a sudden outbreak of inbreeding before their extinction.
In the past, African forest elephant (Loxodonta cyclotis) and African savanna elephant (Loxodonta africana) were both listed as the same species and was a Vulnerable species. recently research shows the habitats and distributions are different for both species, and they rarely overlap. the population of African forest elephant has declined 86% in the past 31 years and is now listed as Critically Endangered; the number of African savanna elephant has dropped 60% in the last 50 years, and it is now listed as Endangered.
habitat for the endangered Zanzibar red colobus is fragmented and continues to shrink because of tourism growth in Zanzibar, Tanzania. in average, a red colobus is killed every 2-3 weeks because of vehicle collisions. To reduce the number of collisions, speed bumps were installed in roads the red colobus frequently cross. with the speed bumps, it helps to reduce the number to 1 collision in 6 weeks. Officials are planning to install more speed bumps in the future to further reduce the risk of collision.
