We live in a very biodiverse region. More than 120 of the species that call our region home are endangered, threatened or of conservation concern. Other species are of interest because of their interactions with humans. Metro Vancouver strives to inventory and conserve habitat for these species and develops specific management plans where appropriate.
While beavers themselves do not pose a significant problem, their work often does. They raise the level of their dam to enlarge their pond, expanding their access to a supply of trees and other resources. This can result in flooding of roads and properties outside the park boundary. Installing a pond-leveler keeps the pond below the flood point, allowing the beavers to continue living in the park, but reducing disruption to their neighbours. Also, the trees beavers cut for their food and shelter provide important habitat to other park animals. Trees in these areas are wrapped with wire or other materials to protect them and the habitat they provide.
Western hemlock looper
An outbreak of western hemlock looper is taking place in Metro Vancouver. Visitors to regional parks such as Capilano River, Lynn Headwaters and təmtəmíxʷtən/Belcarra may notice an abundance of little brown moths as well as damaged (brown) conifer trees. The western hemlock looper is a native species; and the outbreak is part of a natural cycle that happens every 11 to 15 years. The moths lay eggs, which hatch into larvae. Those larvae eat conifer needles – especially those of western hemlocks.
