Clayoquot Sound Biosphere Reserve, British Columbia, Canada - Flores Island


Flores Island (160 km2) lies off the west coast of Vancouver Island in Clayoquot Sound. It can be reached from Tofino by a water-taxi called “Ahousat Pride”. Much of the forests of Clayoquot Sound are in their natural condition, after prolonged legal battles over their fate. Now 6474 km2 have been permanently placed off limits to future logging1 though only fragments have been awarded official protected status. 41 km2 of Flores Island form part of the Flores Island Marine Provincial Park.

 

The only hiking trail on the island is called “Walk the Wild Side”. It runs along the sandy beaches of the southern side of the island except where interrupted by cliffs, when it turns inland through forest. Walking off-trail in the forest is extremely difficult. As a result of frequent storms sweeping in from the Pacific, wind blow is common, opening up the canopy and promoting the formation of a high dense shrub layer. The very mild wet (annual precipitation approx. 3300 mm) climate contributes to the latter. In addition fallen tree trunks lie scattered over the forest floor, and they are BIG.

 

The region belongs to the temperate rainforest zone of the Pacific Northwest, with massive conifers. Near the beaches the forests are dominated by Opens internal link in current windowPicea sitchensis (Sitka spruce). Between the beaches and the P. sitchensis forest there is often a narrow Opens internal link in current windowAlnus rubra (red alder) strip. Both species tolerate salty ocean spray2, 3. Further inland the main tree species are Opens internal link in current windowTsuga heterophylla (western hemlock), Opens internal link in current windowAbies amabilis (Pacific silver fir), Picea sitchensis and Opens internal link in current windowThuja plicata (western redcedar). Alnus rubra grows along the rivers. The diversity of the tree flora is rather modest, but particularly Picea sitchensis and Thuja plicata reach immense proportions. Most species are easy to identify.

 

Note: If you are seeking wilderness silence, this is not the best place in holiday periods. Scenic flights throughout the day from Tofino are very noisy!
