    This guidebook describes the High Peak/Moon Creek Research Natural Area, a ha (1,ac) tract of coniferous forest containing stands dominated by to year-old Douglas-fir, a small old-growth (+ years) Douglas-fir stand, and riparian vegetation within the western hemlock zone of the Coast Range in western Oregon. In this volume, it has been my object to tell of the people and of the picturesque life of the Great Lakes, and to set before my readers actual facts about the cities, the commerce, and the future of the greatest fresh-water seas in the world. For some unaccountable reason, the Great Lakes, notwithstanding the fact that more than thirty million people live in the States bordering their .

Classification of site of forest land is possible on aerial photographs. This classification can be based on topographic features, physiographic features, forest cover types, or on their combinations.

Aerial photographs of the University Research Forest were typed using the following topographic features: exposure, percentage of slope, shape in profile, and shape in. Contents.

Although the conventional methods of predicting growth of trees and stands by the measurements of variables on the ground yield a considerable degree of accuracy, they take a long time and are expensive. Therefore, prediction of growth of trees and stands by the use of aerial photographs as developed herein may be preferable in some situations.

Estimating forest biomass components with hemispherical photography for Douglas-fir stands in northwest Oregon Article in Canadian Journal of Forest Research 41(5). We investigated the capabilities of a canopy height model (CHM) derived from aerial photographs using the Structure from Motion (SfM) approach to estimate aboveground biomass (AGB) in a tropical forest.

Aerial photographs and airborne Light Detection and Ranging (LiDAR) data were simultaneously acquired under leaf-on canopy conditions. A 3D point cloud was generated Cited by: Estimating forest structural attributes of planted forests plays a key role in managing forest resources, monitoring carbon stocks, and mitigating climate change.

High-resolution and low-cost remote-sensing data are increasingly available to measure three-dimensional (3D) canopy structure and model forest structural attributes. In this study, we compared two suites of point Cited by: 8.

Bark beetles (Coleoptera: Curculionidae, Scolytinae) are important disturbance agents in conifer forests. The genera Dendroctonus, Ips, and Scolytus are well recognized in this regard ().For example, in western North America, the mountain pine beetle (Dendroctonus ponderosae Hopkins) colonizes several tree species, most notably lodgepole pine (Pinus contorta Dougl.

Through stereoscopic study of aerial photographs many features of the vegetation and also ground features can be directly identified. This has a practical application in mapping vegetation and soils in upland areas of California.

This paper describes how vegetation types can be identified by analysis of the features visible on aerial photographs. Typing aerial photographs Assuming that aerial photographs of an appropriate scale are available (preferably colour, but or black-and-white are also used), the next step is to delineate (using a stereoscope and grease pencil) logical,homogeneousunits on the photos thatreflect ecological site characteristics.

Because of the poor quality of the available maps, aerial photos were extensively used in iden- tifying areas to be examined within the stratified sample, and in recording site locations.

They were also used in estimating the amount of various kinds of terrain in the area, and amounts of area actually surveyed, in order to offer estimates of. Estimating Canopy Structure of Douglas-fir forest stands from discrete-return LIDAR Trees: Structure and Function.
