Archaeological Sites Dating Back Thousands of Years Found Around Britain, Thanks to the Heat

The archaeologists are mapping the sites to determine the significance of the remains beneath and how best to protect them.

Britain’s hottest summer in decades has revealed cropmarks across the country showing the archaeological sites of Iron Age settlements, Roman farms and even Neolithic monuments dating back thousands of years, archaeologists said Wednesday.

Cropmarks — patterns of shading in crops and grass seen most clearly from the air — form faster in hot weather as the fields dry out, making this summer’s heat wave ideal for discovering such sites.

Archaeologists at the public body Historic England have been making the most of the hot weather to look for patterns revealing the ancient sites buried below, from Yorkshire in the north down to Cornwall in the southwest.

“We’ve discovered hundreds of new sites this year spanning about 6,000 years of England’s history,” said Damian Grady, aerial reconnaissance manager at Historic England.

“Each new site is interesting in itself, but the fact we’re finding so many sites over such a large area is filling in a lot of gaps in knowledge about how people lived and farmed and managed the landscape in the past,” he said.

The archaeologists are mapping the sites to determine the significance of the remains beneath and how best to protect them. While some may be significant enough to merit national protection from development, local authorities or farmers may be left to decide what to do at other sites.

“We’ll hopefully get the help of farmers to help protect some of these undesignated sites,” Grady said. (VOA)

Chinese scientists have revealed how the distribution of abies trees changed in the Quaternary glacial period, providing scientific guidance for the protection of the endangered species against climate change.

As an ancient and typical coniferous species living in southwest China, abies is a good example to study the impact of the ongoing climate changes, which are similar to those in the Quaternary period, on biodiversity in this area, the Xinhua news agency reported.

Researchers from the Chengdu Institute of Biology under the Chinese Academy of Sciences rebuilt the distribution patterns in different periods of four abies taxa to know how they migrated in response to adverse climate.

According to the distribution patterns of abies showed in the study, the researchers suggested that enough corridors should be conserved in Hengduan mountains and the Three Parallel Rivers to protect biodiversity against climate change. Pixabay

They revealed that seasonal fluctuation of temperature and rainfall, rather than average annual temperature and rainfall, was one of the factors that determined the four taxa’s distribution, which means that extreme climate events are major threats to the species.
