Lynn Headwaters Regional Park

Lynn Headwaters Regional Park is an area of North Vancouver, British Columbia, and is the largest of twenty-two regional parks in Metro Vancouver. At , the park boasts a variety of trails for hikers, including easy, intermediate, and challenging. The trails are colour-coded and range from to . Bikes and dogs are allowed on select trails.
Lynn Headwaters is also home to the BC Mills House, which is a small building near the entrance of the park. The BC Mills House offers information and visual depictions of the natural history and industrial history of the area, including kinds of animals that inhabit the forest and locations of previous mines and logging camps.
Ecology.
The park is covered in dense temperate rainforest that houses a wide array of organisms. Like the neighbouring Lynn Canyon Park, Lynn Headwaters is a second growth forest. Cedar stumps can be seen throughout the park, reminding visitors of old logging practices. However, there remain a few scattered trees which are 600 to 700 years old and four to five meters in diameter. 
Lynn Headwaters is situated in Lynn Valley on the North Shore of Vancouver. Lynn Headwaters largely sits between two peaks; on one side, the park area is closer to Mount Fromme, and on the other side is Mount Seymour. The temperate rainforest experiences moderate temperatures, plenty of rainfall, and a mild climate that is suitable for growth of large coniferous trees and shade-loving shrubs and ferns. On average per year, the park receives around of rain, which contributes to the forest's cool and moist quality. The most common coniferous trees in the forests are western red cedar, western hemlock, Douglas fir and sitka spruce. Red alder, black cottonwood, vine maple and broadleaf maple are deciduous trees that also inhabit the forest. Additionally, ground hugging flora are present, including some mosses and ferns, salmonberry, Oregon grape and salal.
Lynn Headwaters is the habitat for a diversity of fauna. Some mammals include squirrels, raccoons, mice, and deer. Amphibians and insects include the salamander, mayfly, caddisfly and stonefly. Also, some birds that are present are red-breasted sapsuckers, winter wrens, owls, crows, chickadees and northern flickers.
History.
Much of the original woody vegetation inhabiting the Lynn Headwaters area has been logged. In 1863, the first lumber mill began operation and cleared most of the old growth trees. Remnants of these giants can be found in old, sizeable stumps. After this logging, of cleared land was donated to the district of North Vancouver with the intention to encourage people to purchase real estate. The district also contributed to supplement the project. In 1991, the district again added of land to the park making it the largest in North Vancouver.
Conservation.
Lynn Headwaters is just off of the Lower Seymour Conservation Reserve (LSCR) area. The Rice Lake trail, which can be accessed from the Lynn Headwaters entrance runs through a part of the conservation reserve. The LSCR is and contains a diversity of landscapes: forested slopes, river flood plains and alpine meadows. Since 1908, the Seymour river has been used as a water supply. It has also been used by gold miners, hunters, farmers and fishermen. Until 1994 with the ceasing of logging, watershed land has since been used as a water treatment, storage, and delivery facility. Currently, it is used for educational purposes that emphasize environmentally notable land management practices.
Trails.
Lynn Valley Regional Park offers a variety of hiking trails ranging in difficulty. Near BC Mills House, a number of picnic tables are available and separate male and female outhouse washroom facilities.
