This book was released on 2010 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: To support Marbled Murrelet (Brachyramphus marmoratus) strategic planning initiatives in the Central Coast region of British Columbia, the Ministry of Environment had 1.5 million hectares of forest mapped for potential nesting habitat quality using a six-class (Nil to Very High) air photo interpretation classification system. This classification evaluates attributes, such as tree size and canopy complexity, that are indirectly associated with potential nesting platform occurrence, on 1:10 000/1:15 000 air photos. We verified the habitat classifications of the air photo inventory maps using helicopter lowlevel aerial surveys.

Book Synopsis Interpretation of Habitat Quality from Air Photos at Marbled Murrelet Nest Sites in Mussel Inlet on the British Columbia Central Coast by : Frances M. Louise Waterhouse
Download or read book Interpretation of Habitat Quality from Air Photos at Marbled Murrelet Nest Sites in Mussel Inlet on the British Columbia Central Coast written by Frances M. Louise Waterhouse and published by . This book was released on 2011 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: We used newer, larger-scale 2007 colour air photos to interpret habitat attributes and classify habitat quality of 14 Marbled Murrelet (Brachyramphus marmoratus) nest sites identified in 1992 (n = 2) and 1999 (n = 12) in Mussel Inlet on the Central Coast of British Columbia. Mussel Inlet is a fjordland environment atypical of other areas for which the air photo interpretation classification has been tested using nest sites (i.e., Haida Gwaii, Vancouver Island, and south coastal British Columbia). Nesting habitat described by 3-ha plots centred on the nest site was characterized in Mussel Inlet as having complex canopies with large trees in mid to low meso slope positions, and as such is comparable to that reported elsewhere in British Columbia. However, comparisons of the nest plot habitat attributes to those at 27 random plots also suggested that interpretations of murrelet habitat selectivity for Mussel Inlet differed from other coastal areas due to differences in characteristics and availability of forest structures. Overall in Mussel Inlet, more nest plots were classed as lower quality (i.e., 50% Low and Very Low) on air photos compared to other British Columbian studies (i.e., ~14% Low and Very Low). Although selectivity testing based on air photo habitat class was inconclusive, particularly for the High and Very High quality habitats for which limited habitat was available (~1 % of the study area), a trend was indicated for higher proportional use of Moderate and Low habitats and lower proportional use of Very Low habitats. We discuss limitations of the samples used for this study and issues in interpretation, resolution, and scale in applying the air photo methods in topographically complex, fjordland landscapes such as Mussel Inlet. Given these limitations and issues, we recommend use of aerial survey methods to confirm occurrence of nest platforms.

This book was released on 2012 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Air photo interpretation (API) is widely used in British Columbia for assessing and mapping forest nesting habitat of the Marbled Murrelet (Brachyramphus marmoratus). For strategic land use planning in Haida Gwaii, the entire land base (approximately 1 million ha) has been mapped based on polygons assessed with API. The API method does not, however, detect microsite features in the forest canopy, especially the presence of mossy mats and other potential nest platforms, which are essential for murrelets to nest. This study was therefore undertaken to compare the API habitat quality classifications with those made by low-level helicopter surveys (aerial surveys), which focus on the canopy structure and the presence of potential nest platforms."--Document.

Book Synopsis Nest Structures and Habitats of the Northern Spotted Owl in Three Ecological Subregions of British Columbia by :
Download or read book Nest Structures and Habitats of the Northern Spotted Owl in Three Ecological Subregions of British Columbia written by and published by . This book was released on 2012 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fourteen nest sites of the endangered Northern Spotted Owl (Strix occidentalis caurina) in British Columbia were sampled in 2003 and 2004. Nests were located in three broad ecosystem types: the maritime (n = 1), submaritime (n = 6), and continental (n = 7) ecological subregions. Spotted Owls exhibited flexibility in their use of different types of nest structures across their broad ecological distribution. The objectives of the analyses are (1) to describe 14 of the 16 known nest structures, nest patches, and nest stands relative to the ecological subregions in which they occur; (2) to test for habitat selection within the nest stand (patch-level) and within the local landscape that the authors defined as the area containing the forest nest stand and forest stands greater than 140 years old adjacent to it (stand-level) relative to the ecological subregions; and (3) to evaluate how local British Columbia nesting habitat information was incorporated into interpreting "Superior" owl habitat for a revised spotted owl management plan.--Document.

Book excerpt: This volume represents a first attempt at holistically classifying and mapping ecological regions across all three countries of the North American continent. A common analytical methodology is used to examine North American ecology at multiple scales, from large continental ecosystems to subdivisions of these that correlate more detailed physical and biological settings with human activities on two levels of successively smaller units. The volume begins with an overview of North America from an ecological perspective, concepts of ecological regionalization. This is followed by descriptions of the 15 broad ecological regions, including information on physical and biological setting and human activities. The final section presents case studies in applications of the ecological characterization methodology to environmental issues. The appendix includes a list of common and scientific names of selected species characteristic of the ecological regions.
