Road Ecology and Wildlife Crossings

This is the third and final post in a series looking at wildlife movement, corridors and roads. Read the first post, Ecology Lesson: Population Movements, which was followed by Corridor Ecology and Planning.

Roads

Roads crisscross the entire country covering much of the land. Highways take us through states or across the whole country, streets cover cities and dirt roads link rural areas to cities. They traverse over rivers, lakes, mountains, valleys, deserts and forests. Some highways are many lanes wide and some bridges are modern engineering marvels. They bring us commercial goods, foods and fuel across great…

Corridor Ecology and Planning

This is the second post in a series looking at wildlife movement, corridors and roads. The full series: Ecology Lesson: Population Movements,  Corridor Ecology and Planning and Road Ecology and Wildlife Crossings.

Wildlife needs to move for many reasons which were discussed in Ecology Lesson: Population Movements. There are many barriers in the urban landscape that prevent or make movement difficult for wildlife. Among the many barriers are roads including small streets to major highways, development such as shopping centers or subdivisions, railroad lines, powerline corridors, canals, dams and non wildlife-friendly landscapes such as…

Ecology Lesson:: Population Movements

This is the first post in a series looking at wildlife movement, corridors and roads. The full series: Ecology Lesson: Population Movements,  Corridor Ecology and Planning and Road Ecology and Wildlife Crossings.

This is also the second post in the Ecology Lesson series, the first being The Basics.

There are three categories of wildlife movement, the first being contained in a ‘home range’ or an area that is usually occupied by a population where individuals or groups travel daily or populations move as a group to another area inside their home range. Some animals have large…

A Roof for the Birds:: Creating habitat on the Portland Mausoleum roof

This is my comprehensive project that I completed in my final year of the Landscape Architecture program at the University of Oregon. The two-term project was the culmination of my educational career and I wanted to choose something meaningful that would relate to my main interest of creating and designing urban wildlife habitat. I started to ask around and very quickly a project fell into my hands from Mike Houck, the Executive Director of the Urban Greenspace Institute in Portland. He has been responsible for creating Oaks Bottom Wildlife Refuge as well as a giant mural on the side of…

City Lights and Urban Wildlife

Artificial lighting affects not only our ability to see the stars, but it affects a great many aspects of the ecology of wildlife. Light can impact wildlife directly by streetlights or lit buildings, or more indirectly with sky glow, the light from combined city lights. It can affect many difference facets in the lives of wildlife including feeding, migrating, mating and even sleeping and in the worst instances it results in death.

One of the more well known and better documented examples is the impact of lights along beaches on newly hatched turtles. Once hatched from their eggs the young…
