and ecology, said that "the overall effect was positive" for the wildlife in the area. The impact of radiation on individual animals has not been studied, but cameras in the area have captured evidence of a resurgence of the mammalian population – including rare animals such as the lynx and the vulnerable European bison. Research on the health of Chernobyl's wildlife is ongoing, and there is concern that the wildlife still suffers from some of the negative effects of the radiation exposure. Though it will be years before researchers collect the necessary data to fully understand the effects, for now, the area is essentially one of Europe's largest nature preserves. Overall, an assessment by plant biochemist Stuart Thompson concluded, "the burden brought by radiation at Chernobyl is less severe than the benefits reaped from humans leaving the area." In fact, the ecosystem around the power plant "supports more life than before". Infrastructure The industrial, transport, and residential infrastructure has been largely crumbling since the 1986 evacuation. There are at least 800 known "burial grounds" (Ukrainian singular: mohyl'nyk) for the contaminated vehicles with hundreds of abandoned military vehicles and helicopters. River ships and barges lie in the abandoned port of Chernobyl. The port can easily be seen in satellite images of the area. The Jupiter Factory, one of the largest buildings in the zone, was in use until 1996 but has since been abandoned and its condition is deteriorating. However, the infrastructure immediately used by the existing nuclear-related installations is maintained and developed, such as the railway link to the outside world from the Semykhody station used by the power plant. Chernobyl-2 The Chernobyl-2 site (a.k.a. the "Russian Woodpecker") is a former Soviet military installation relatively close to the power plant, consisting of a gigantic transmitter and receiver belonging to the Duga-1 over-the-horizon radar system. Located from the surface area of Chernobyl-2 is a large underground complex that was used for anti-missile defense, space surveillance and communication, and research. Military units were stationed there. Media depictions Immediately after the explosion on 26 April 1986, Russian photographer Igor Kostin photographed and reported on the event, getting the first pictures from the air, then for the next 20 years he continued visiting the area to document the political and personal stories of those impacted by the disaster, publishing a book of photos Chernobyl: confessions of a reporter. In 1993, the official video for
