  • Raptor Nest Survey Summary Report
    Raptor Nest Survey Summary Report Lot 5 UBC South Campus January 6, 2020 Submitted to: Polygon Homes Ltd. Raptor Nest Survey Summary Report 1.0 Introduction 1.1 Project Background Diamond Head Consulting Ltd. (DHC) was retained to conduct a raptor nest survey for the proposed development of Lot 5 into a parkade at the University of British Columbia (UBC) South Campus. The development requires the removal of all trees from an existing natural area. As part of this project, on‐ site tree planting is planned upon completion of the parkade. A nest survey is required prior to construction activity to ensure compliance with the federal Migratory Birds Convention Act [1994] and attendant Migratory Birds Regulation [1994] that protects migratory birds, their eggs, and nests. Also, Section 34(a), (b), and (c) of the provincial Wildlife Act [1996 chap 488] prohibits the taking of birds, eggs, and nests. Nests of eagle, peregrine falcon, gyrfalcon, osprey, heron, and burrowing owl are specifically protected whether or not they are active. 1.2 Site Description The project site is a second growth forested area south of W 16th Ave and east of SW Marine Dr, on the corner of Berton Ave and Binning Rd within the UBC South Campus (Figure 1). The nest survey was conducted within the project site and in the forested area immediately adjacent to the north and east. Figure 1 – Project location, UBC South Campus Lot 5, Vancouver, B.C. 3559 Commercial Street, Vancouver B.C. V5N 4E8 | T 604‐733‐4886 1 Raptor Nest Survey Summary Report The project site and adjacent natural areas are a native second growth forest stand mainly consisting of Western Red Cedar (Thuja plicata), Western Hemlock (Tsuga heterophylla), Douglas Fir (Pseudotsuga menziesii), and Bigleaf Maple (Acer macrophyllum).

All of Australia'sthree threatened, diurnal speciesare endemic to the continent. One, the Vulnerable Red Goshawk (Erythrotriochisradiatus), is endemic to Australia's tropical forestsand is under threat from lossof habitat, persecution,and egg collecting.Conservation efforts include legal protection, education, and keeping nest sitessecret. A secondspecies, the rare Square-tailedKite (Lophoictiniaisura) is widelydistributed and, exceptfor clearingof woodland,threats are not obvious.Many raptors from arid areas,including the endemic Grey Falcon (Falcohypoleucos), "winter" in tropicalwoodlands. For adequateconservation, critical habitatsof the Grey Falconmust be identified. Grey Falconsshould be helped in the long term by the anticipatedreduction of rabbitsin arid Australiaby rabbit calicivirusdisease, but widespreadclearing of tropicalwoodlands for agriculture continuesas does local, heavy use of pesticides.Although no speciesof owls are threatened, five sub- speciesare; two are subspeciesof the endemic RufousOwl (Ninox rufa, one rare and one insufficiently known) and two are subspeciesof the Masked Owl (Tyt0 novaehollandiae,both insufficientlyknown). Threats include lossof critical habitat to fire and agriculture.On ChristmasIsland, the smallpopulations of endemicsubspecies of the BrownGoshawk (Accipiterfasciatus) and MoluccanHawk-owl (N. squamipila) are Vulnerable and threatened by loss of habitat to urbanization and formerly mining. Besideslegal protection, conservationefforts have included educationand habitat preservation.The tropicalEastern Grass-owl(T. longimembris)is secure although some populationsare under pressurefrom agriculture (including rodenticides) and urbanization.

  • Management Tools for Raptor Conservation
    Chancellor, R. D. & B.-U. Meyburg eds. 2004 Raptors Worldwide WWGBP/MME Management Tools for Raptor Conservation R.E. Kenward ABSTRACT Following the Convention on Biological Diversity, the focus in Europe on protection-based conservation is starting to be complemented by the incentive- driven approaches that have been more widespread elsewhere, to give "dual- approach" conservation. Incentive-driven approaches build conservation on the use of wild resources, which must be sustainable, typically using public funding for ecosystem services and private funding for more direct benefits such as ecotourism and extractive use. Whereas the "protect-and-reserve" has been strongly educational, the "sustain-by-use" approach can be less polarising in societies and landscapes, although it is also much more complex and thus harder to apply. It requires new tools, both ecological and socio-economic, especially to encourage cooperation between the variety of stakeholders involved in the conservation of raptors, including landowners, game managers, falconers, other wildlife organisations and governments. This paper concentrates on tools for encouraging falconers and other hunters to contribute to conservation of raptors. It presents new survey data to indicate that poisoning of raptors is least where governments have a most conciliatory attitude to prédation problems, and that use of hybrids in falconry is least where governments permit harvest of wild raptors. It recommends that hunters work for recognition of their conservation benefits while governments and other conservation interests encourage public understanding of wild resources as renewable. It recommends that falconers be encouraged to contribute to conservation of wild raptors in exchange for permiaed harvest, especially by adopting systems that ensure that traditional use of Saker Falcons is sustainable and beneficial.
