A joint event with Lighthouse Park Preservation Society
Trip Report by Leader, David Cook
On June 25, 2019, nineteen participants strolled along the trails of Lighthouse Park, West Vancouver. In the most pristine low elevation old-growth forest on the North Shore, we had an easily accessible opportunity to view this type of forest. While the main theme of the day was old-growth ecology and the characteristics of an old-growth forest, subthemes were plant dispersal, fire history and the valiant attempts of the Lighthouse Park Preservation Society to remove invasive plant species and replanting with native species protected by dog-proof fencing. Each plant species had a story to tell beyond the names that they had been given by humans. A couple of those stories are worth mentioning; the unusual ways in which foam flower and bleeding heart have in dispersing their seeds by launching of a specialized bract and by ants respectively. We were able to observe a tree pool in the cleft between two fused redcedars, a type of micro-ecosystem which has the potential to yield new compounds of therapeutic value.
