Alqueva: Minimizing the barrier effect and trap wildlife 4 films on display at edia.
A set of four films are on display in edia headquarters, in Beja, illustrating the work on monitoring the effectiveness of measures to minimize the barrier effect and the trap effect on the Multi Purpose Development of channels of Alqueva.
These four films, which are passing in a continuous, They are the result of a selection of films and fauna photographs and represent a part of the vast collection of information obtained in the context of this work. The movies, with 15 minutes each, They can be seen weekdays, entre as 09.00 e as 18.00 hours.
The Development of Multiple Purposes of Alqueva (EFMA) It consists of a set of infrastructure that enable the transport of water between different reservoirs. Some of these infrastructures are adduction channels in the open, the extension being monitored by EDIA is 81,5km.
This water transport network covers a variety of habitats where it induces the barrier effect and effect trap affecting wildlife species that occur in the area crossed by canals. To minimize the barrier effect were included along the channel hydraulic passages, upper and lower channel regions and covered. These passages allow the crossing of several species contributing to reduce the barrier effect.
To minimize the effect trap were built in the rescue and output channels was installed ramps and specific seal to prevent the entry of animals in the surrounding area of ​​the channel and increase the possibility of channel output in case of a fall, reduction contributing to trap effect.
Monitoring the effectiveness of mitigation measures implemented is performed by a team field of EDIA, from 2007, which applies several methods of monitoring the use of passages including the observation rails, footprints, droppings and other clues, and by filming color or infrared, especially relevant during the night, during which is a large number fauna circulation in the area of ​​influence of the EFMA.
Note that, the various infrastructures in question do not cross any protected or classified area under the legislation in force, It was not identified, under the Studies and Environmental Impact, the direct concern of populations of species with an unfavorable conservation status. Despite this minimization measures were implemented, which can be seen in 4 Films Now Playing.
