Blodgett Tract

waterfallThe Blodgett Tract, located in the hills immediately above the Columbia River floodplain, is very productive. Following railroad logging in the late 1920’s, a 1934 escaped slash fire created an excellent seed bed. Today, natural regeneration of Douglas-fir and western hemlock provide approximately 2.5 MMBF of growth per year. Coho salmon and other anadromous fish species spawn in the Tract's clear streams.

Site Description

The Blodgett Tract is a 2,440 acre forest located in Columbia County about four miles south of the Columbia River in the upper Nehalem basin. The western boundary of the tract is the Clatsop County line which is also the eastern boundary of the Clatsop State Forest. The other three sides of the tract are surrounded by private industrial forest lands. The upland conifer stands are predominantly Douglas-fir and western hemlock with a small amount of western redcedar and Sitka spruce. Riparian areas are dominated by red alder that is some areas is mixed with Douglas-fir, western redcedar and Sitka spruce. The Tract is underlain by marine sedimentary rock. The rock is composed of tuffaceous silts and sands that were derived from sand and volcanic debris from landmasses to the east, and were laid down when this area was shallow sea. There are intrusions of basalt in the sedimentary rock that were intruded when the rock was still submarine. These basalt intrusions show up in road cuts on an irregular basis. The sandstone is very incompetent and thus weathers easily. This is evidenced by an almost complete lack of bedrock outcrops on the forest, including the road cuts.
