CEMENTery

Millions of years ago, a cluster of coral reefs stood firm here as the water receded, leaving them surrounded by the marshy, mangrove-studded Mekong Delta.

Today, these reefs have been carved by the wind and rain into spiky limestone cliffs known as karsts that stand stark against the Cambodian landscape, even as the lowland rain forest around them has been denuded by centuries of intensive rice cultivation and logging.

Soon, they will be gone.

According to the International Union for Conservation of Nature (IUCN), the Karst hills in southeast Cambodia have been for the most part left unstudied and are unique due to the presence of highly specialized flora which is found only in this ecosystem.

Captions CHROKCHEY VILLAGE, CAMBODIA – JANUARY 20: View of the Kampot Cement facility set up on the hill side of Tuok Meas Mountain on January 20, 2017 in Chrokchey Village, Cambodia. Kampot Cement is the largest producer of cement in Cambodia. It is estimated that Cambodia's annual demand for cement is over 5 million tons a year. New cement plants are in the process of being built in Kampot and Battambang provinces, which would raise the annual production of Cambodia's cement significantly. The furious development of the country has increased significantly the need to produce local cement in order to cut costs on imported cement, which currently increases the price of constructing buildings in Cambodia.

Kampot Cement is the largest producer of cement in Cambodia and its cement production facility is located only a dozen kilometers away from Kampong Trach Mountain. The factory opened in 2008 and has a production capacity of almost a million tons of cement per year. The cement is produced from the limestone of the Kampot Karst, putting in danger the ecosystem of this unique area. Photo: © Omar Havana for The New York Times

Andrew McDonald (62), Associate Professor at the University Texas Rio Grande Valley, points at the location where the expedition team need to get to during their daily search for unknown flora species on January 20, 2017 in Phnom Kampong Trach (Kampong Trach Mountain), Cambodia. A team of seven national and international members explore for the first time the flora of the limestone mountains known as Phnom Kampong Trach as part of the Kampot Karst Conservation project by the International Union for Conservation of Nature (IUCN) aimed to a floristic reconnaissance of a never-before studied area of Cambodia that could help to declare the area as protected.

A team led J. Andrew McDonald is studying rare and endemic plants that grow in the Karst hills of Phnom Kampong Trach, as part of the Kampot Karst Conversation Project of the International Union for Conversation of Nature (IUCN). McDonald and his team have already discovered one floral species - part of the Amorphophallus family - which had never been discovered before. Photo: © Omar Havana for The New York Times

Members of the expedition team are exploring these unknown areas of Phnom Kampong Trach, taking risks while trying to find paths that will allow them to explore as deeply as possible in the mountain in order to find as many unknown flora species as they can in an attempt to convert these threatened limestone formations into protected areas and to avoid their exploitation for the cement industry.

For each unknown species found during the mission, the team collects five samples, some of which will become part of Cambodia's National Herbarium very small collection of 10,000 species. Other samples will be sent to research labs in Vietnam and the United States to be studied and archived. Photo: © Omar Havana for The New York Times

Although it may seem like an important discovery, collecting specimens is only a first step in examining the ecosystem of the Kampot Karst and will need to be studied over the next few months by American and Vietnamese botanists to determine which are endemic to the hills.

Sam An has been living all his life near the limestone mountains of Kampong Trach, which he patrols on a daily basis in order to protect the trees and stones from illegal exploitation. His extensive knowledge about the area is of great help to the expedition team in finding new areas where to search for unknown flora species. Photo: © Omar Havana for The New York Times

Andrew McDonald collect specimens of unknown species at the entrance of a gigantic cave known as the "Bat Cave" on January 20, 2017 near Kampong Trach, Cambodia. The nature of limestone habitats means that, often, a particular species may only flourish in a very small area – such as these caves – and as a result, even a single extractive quarry can result in a global extension of that particular species – something which has already happened in other areas of the world.

Photographs taken during this trip by the Vietnamese researchers will be included in a photography project led by Luu Hong Truong. The project has already photographed already more than 4,000 species and is currently looking for funds to start increasing the photography archives of the Academy.

After collecting the specimens, the team places them inside newspaper pages and cardboard to start the pressing process during which specimens are flattened out to their maximum. After setting up the presses, these are placed in a metallic structure covered by cardboard where a heater is placed at the bottom of the structure. The drying process can last for up to seven days, during which constant heat is applied to the specimens. After being dried, specimens will be placed inside a freezer set up at -70° C to kill any insects and bugs for five to seven days. Once this whole process is finished, the specimen can survive for hundreds of years. Photo: © Omar Havana for The New York Times

Quarrying these hills is the biggest threat to the species that flourish in the environment, and will worsen Southeast Asia's biodiversity crisis. Photo: © Omar Havana for The New York Times

Samora, a 27-year-old worker at Kampot Cement who makes USD 170 a month working as an electrician for the company, buys the limestone from illegal miners who hammer out the limestone in some of the mountains in the area and sells it after to private buyers as a building material for their homes or construction projects.

Figures released by the Cambodian Ministry of Land Management at the beginning of January 2017, the 2,636 construction projects approved in 2016 alone are valued at more than USD 8.5 billion – twice the value of construction projects in 2015. This rapid economic development is threatening the natural ecosystems of the limestone of the Kampot Karst. Photo: © Omar Havana for The New York Times

Captions PHNOM PENH, CAMBODIA – JANUARY 25: Dozens of new apartment buildings under construction are seen from a rooftop at the Russian Market on January 25, 2017 in Phnom Penh, Cambodia. In recent years the cityscape of Phnom Penh has changed drastically; high-rise buildings and concrete houses have replaced what were once French colonial buildings and traditional tin roof houses, progressively giving way to a new city that will still be under construction for years to come. Thousands of new apartments are planned to be built in Phnom Penh over the next 10 years, placing an increasing danger on the limestone of Cambodia. Photo: © Omar Havana for The New York Times
