KLGO is a part of the North American Northwest Coast environmental region, also known to geographers and geologists as Cascadia (Ames and Maschner 1999). The park maintains ecological importance. Lynn Canal is a saltwater fjord which pierces deep into the heart of the Coast Mountains. The Taiya and Skagway valleys provide short pathways to glacier-free mountain passes connecting to the continental interior. KLGO remains the northernmost and furthest inland conduit for ecological exchange between the coastal rainforest ecosystem and the interior continental ecosystem. The park contains a variety of habitats including coastal rainforest, subalpine, and alpine. Each habitat is diverse, unique, and relates to its neighboring community.
The diversity of plant and animal species in the Upper Lynn Canal remain among the highest in Alaska. Subarctic alpine, boreal forest, north coast forest, and marine systems converge at KLGO and the park hosts species assemblages found nowhere else in the world. Vegetation distribution is governed by a number of factors including soil type, depth, drainage, light availability, precipitation, temperature, disturbance patterns, and aspect and elevation. Specific vegetation communities in the park are not restricted to specific terrestrial ecological units and communities typically …show more content…

Temperature during the summer ranges from 46 to 80 degrees and the mean temperature during the winter is 58 degrees (Mulligan 2015). Spring thaw occurs around late April or early May, the mean annual precipitation is 27 inches (69 centimeters), and the annual snowfall is around 46 inches (117 centimeters) (Mulligan 2015). The climate at KLGO remains unique compared to the rest of southeast Alaska which is typically a “wet maritime climate with a mean annual precipitation of more than 160 inches” (Mulligan
