This book was released on 2012 with total page 22 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.

Download or read book A Framework to Support Landscape Analyses of Habitat Supply and Effects on Populations of Forest dwelling Species written by Glenn Douglas Sutherland and published by . This book was released on 2007 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document outlines a spatial modelling framework relevant to managing forest-dwelling species. The northern spotted owl, an endangered Species at Risk, is used as the case study for framework development and application. The authors present results from development of the component models and from the testing of biological hypotheses and sensitivity analyses of biological assumptions about the northern spotted owl and its ecology. Further they demonstrate application of the framework for assessment of management options for the northern spotted owl and towards identifying critical habitat. This project was undertaken in collaboration with the Canadian Spotted Owl Recovery Team, and the document also outlines the collaborative approach used to address species recovery.--Publisher's website.

This book was released on 2010 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large-scale, integrative decision support tools and models are often used to represent resource management problems and guide management policy. However, such tools and models can be difficult to validate and even more difficult to verify. This creates uncertainties in how best to use model results to inform development of management policy. We used a historical data set of detections of the endangered Northern Spotted Owl (Strix occidentalis caurina) in British Columbia to examine the degree of correspondence between projections of quantity of suitable habitat and its configuration as generated by a spatially explicit modelling framework, and broad classes of area occupancy by owls observed in detection surveys between 1992 and 2001. We found that among spatial scales of analysis, as well as between two time periods (2004 landscape and reconstructed 1984 habitat projections), the projected patterns of habitat suitability and connectivity were as predicted assuming that occupancy of areas by owls is positively related to these factors. However, we could not consistently demonstrate statistical significance for these relationships at all the spatial scales and the two time periods examined. While our results do not offer direct ecological support for the effect of habitat quantity and configuration on observed trends in Northern Spotted Owl populations in British Columbia, they increase confidence in the parameters and structural assumptions in the habitat portion of the model. We caution that because of data limitations, our results should be treated as an exploration of the implications of important assumptions rather than as strict tests of the influence of habitat variables on population trends. The amount and distribution of habitat is clearly an important issue for conservation and management of Northern Spotted Owls in British Columbia. However, until we better understand the way in which Barred Owls influence Northern Spotted Owls, insights from analyses such as those used in this study may be constrained. Currently, the relative influences of habitat, Barred Owl effects, and other stochastic effects of small population size on detect-ability and distribution patterns of Northern Spotted Owls cannot be fully separated in the type of analysis used in this study.
