Marcel Huijser Photography Home
This is where I show the most recent images and talk about how they were made. The images typically relate to landscapes and wildlife, but I also blog about photos of highways and mitigation measures for wildlife or road ecology in general. Please contact me if you would like to use any of the images.

Road ecology blog: Speed reduction, radar, rumble strips, wildlife warning signs, Brazil
Highway RS-486 bisects a forest remnant (Reserva Biológica Mata Paludosa), Rio Grande do Sul, Brazil. The posted speed limit has been reduced to 40 km/h and this enforced by a fixed location radar post. Additional measures include a wildlife warning sign and rumble strips. The rumple strips leave a narrow smooth path on the pavement for the vehicle tires.

Road ecology blog: White-eared opossum roadkill with dead young, Rio Grande do Sul, Brazil
Road ecology blog: White-eared opossum (Didelphis albiventris) roadkill with dead young, Rio Grande do Sul, Brazil. Opossums do have a placenta, but the young are born at a very early stage of development. The young find their way to the marsupium (pouch) where they latch on to a teat. In the images below the young have crawled out of the marsupium looking for warmth and milk, presumably shortly after the mother was struck by a vehicle and died. The young had no chance for survival, obviously, and died as well.

Road ecology blog: Tunnel (landscape bridge), Rio Grande do Sul, Brazil

There are no strict rules on how to classify a wildlife crossing structure. However, "wildlife overpasses" tend to be specifically build to allow wildlife to pass to the other side of the road. The dimensions and "furniture" (e.g. soil, cover, vegetation, ponds on either side) of a wildlife overpass are typically designed with certain "target species" in mind. The appropriate width of the structure (i.e. the road length covered by the structure) is often a topic of discussion, but most structures are between 30-70 m wide. While most wildlife overpasses do have soil and vegetation, they tend to not be designed to have a wide range of ecosystem processes continue across the road. Ecosystem processes may not only include movements of a wide variety of plant and animal species groups representative for the ecosystem, but also soil and hydrology processes.
Long road tunnels and long bridges (elevated roadways) are typically several hundreds of meters up to several kilometers wide (i.e. the road length covered or spanned by the structure). They have relatively "undisturbed" soil and water on top or below the structure which make them better suited to have ecosystem processes continue under or over the road compared to wildlife overpasses. In this context these large structures can be regarded as a "landscape bridge" rather than just a wildlife crossing structure. However, long tunnels or bridges tend to be primarily build for other reasons (e.g. a mountain or floodplain is in the way of the road). While most long tunnels or elevated roadways are not primarily designed for ecological processes to continue over or under the road, they do have great potential to function as a landscape bridge.
