Human activities affect wildlife even in nature reserves

"...The study used results from one of the largest long-term standardized camera-trap wildlife surveys to date. It produced millions of camera images, which researchers analyzed to see how human activity has affected 159 mammal species in 16 protected areas across tropical regions on three continents. The camera traps across 1,000 sites collected images over up to 10 years across tropical forests..."

Preserving the Natural Jewel: Join the Movement to Protect Gatineau Park Nature Canada

"...One of the major concerns is the encroachment of urbanization and development in the surrounding areas. The absence of an adequate land-use strategy between the park and adjacent development zones has led to habitat fragmentation and increased human presence at the park's edges. The encroachment of urbanization and development in the areas surrounding Gatineau Park has led to a concerning level of habitat fragmentation, which not only disrupts the park's delicate ecological balance but also poses significant risks to the well-being of both wildlife and human populations..."

Keremeos Columns protected area to grow ten-fold

"...“Recovering Canada’s species at risk and restoring biodiversity requires local, regional and national action. Conservation efforts at the Keremeos Columns Grassland is a terrific example of how we can work together with partners to protect nature, build ecological corridors and help species at risk,” said Minster of Environment and Climate Change Steven Guilbeault. “The Government of Canada is committed to conserving 25 percent of Canada’s land and inland waters and 25 percent of oceans by 2025, and is working toward 30 percent of each by 2030..."

The Nature Trust of BC Purchases 479 Acres of the Keremeos Columns Grasslands to Conserve Crucial Similkameen Biodiversity

"...The Keremeos Columns Grassland conservation area is located in the Similkameen Valley within the traditional territory of the Smelqmix and Syilx Peoples. The conservation area is adjacent to the 20 hectare Keremeos Columns Provincial Park, increasing the size of the protected land by almost ten-fold and connecting seven crucial and sensitive ecosystems..."

Restoration at a Snail's Pace

"...The Oregon Forestsnail is endemic to western North America and as an adult, it is identified by a thick white apertural lip (the lip surrounding the opening of a snail shell) and a deep central pit (the central hole on the underside of the shell). The shell is pale brown or straw-yellow and ranges from 28 to 35 mm. Since large native land snails are rare in the coastal forests of BC, the Oregon Forestsnail is a valuable component of the biodiversity of these environments..."

World Habitat Day 2021: There is no protected habitat too small to benefit biodiversity

"...Returning to cities, the implications of Lenore’s work are exciting. If even small, fragmented patches of habitat are important for biodiversity conservation, we can no longer overlook cities. Every patch of native habitat counts, including your favourite local forest or wetland..."

Wildlife Wednesday: Animals are shape-shifting to cope with climate change

"...Before the COVID-19 pandemic, University of Ottawa student Megan Reich embarked on a 74-day, 20,000 kilometre scientific odyssey over 22 states to better understand the migration pathway of monarch butterflies. Since then, shes been crunching data on milkweed distribution the host plant for monarchs with the results published in Methods in Ecology and Evolution this week. Reich and colleagues from the University of Guelph and the University of Marylands Center for Environmental Science matched up strontium isotopes different variations of the same atomic element from milkweed and butterfly samples to track the monarchs and more precisely pinpoint where monarchs were born, and how migratory routes are connected..."
