Design Guidelines For Shop Buildings In Beypazari Historic Commercial Center

Genca, Salih Ozgur 01 March 2005 (has links) (PDF)
This study aims to prepare a design guide for the traditional shop buildings in Beypazari Historic Commercial Center which guides maintenance, repairs and new designs on shop facades. This guide, which is prepared in limited content by researching problems of conservation in historic towns also aims to develop a collaboration of the users and the municipality, to raise the consciousness of the community for conservation, and to be an example for similar studies. During this process, a detailed study is made on architectural conservation guides and shop buildings in the study area.

Restoring monarch butterfly habitat in the Midwestern US: ‘all hands on deck’

Thogmartin, Wayne E, López-Hoffman, Laura, Rohweder, Jason, Diffendorfer, Jay, Drum, Ryan, Semmens, Darius, Black, Scott, Caldwell, Iris, Cotter, Donita, Drobney, Pauline, Jackson, Laura L, Gale, Michael, Helmers, Doug, Hilburger, Steve, Howard, Elizabeth, Oberhauser, Karen, Pleasants, John, Semmens, Brice, Taylor, Orley, Ward, Patrick, Weltzin, Jake F, Wiederholt, Ruscena 01 July 2017 (has links)
The eastern migratory population of monarch butterflies (Danaus plexippus plexippus) has declined by >80% within the last two decades. One possible cause of this decline is the loss of >= 1.3 billion stems of milkweed (Asclepias spp.), which monarchs require for reproduction. In an effort to restore monarchs to a population goal established by the US Fish and Wildlife Service and adopted by Mexico, Canada, and the US, we developed scenarios for amending the Midwestern US landscape with milkweed. Scenarios for milkweed restoration were developed for protected area grasslands, Conservation Reserve Program land, powerline, rail and roadside rights of way, urban/suburban lands, and land in agricultural production. Agricultural land was further divided into productive and marginal cropland. We elicited expert opinion as to the biological potential (in stems per acre) for lands in these individual sectors to support milkweed restoration and the likely adoption (probability) of management practices necessary for affecting restoration. Sixteen of 218 scenarios we developed for restoring milkweed to the Midwestern US were at levels (>1.3 billion new stems) necessary to reach the monarch population goal. One of these scenarios would convert all marginal agriculture to conserved status. The other 15 scenarios converted half of marginal agriculture (730 million stems), with remaining stems contributed by other societal sectors. Scenarios without substantive agricultural participation were insufficient for attaining the population goal. Agricultural lands are essential to reaching restoration targets because they occupy 77% of all potential monarch habitat. Barring fundamental changes to policy, innovative application of economic tools such as habitat exchanges may provide sufficient resources to tip the balance of the agro-ecological landscape toward a setting conducive to both robust agricultural production and reduced imperilment of the migratory monarch butterfly.
