The Future of Camellia Oilseed Species in a Changing Climate

Future of Camellia Oilseed Species in a Changing Climate

A Glimpse into Four Major Camellia Species

Camellia oilseed species, including Camellia Chekiangoleosa, Camellia Drupifera, Camellia Oleifera, and Camellia Reticulata, are crucial for both economic and ecological reasons in China. Known as traditional oilseed species, they have been cultivated for over 2000 years, primarily in the southern regions of China. These species, producing the revered tea oil, offer a plethora of health benefits due to their rich content of unsaturated fatty acids and natural antioxidants​​.

Impact of Climate and Land Use Changes

The shifting climate and changing land use patterns significantly influence the distribution of these species. Recent studies emphasize the interconnectedness of climate and land use changes in shaping species’ distribution. As the environment evolves, the suitable areas for these species also change, highlighting the need for adaptive conservation and cultivation strategies​​.

The Importance of Persistent Suitable Areas

Persistent suitable areas, essentially in situ refugia, are regions that remain suitable for species despite environmental changes. These areas are pivotal for conserving existing populations and ensuring their survival during extreme climate events. Identifying these areas is crucial for strategic conservation and plantation planning, particularly in the context of global warming​​.

Species-Specific Responses to Environmental Changes

Each of the four Camellia species exhibits unique responses to environmental changes. Camellia Chekiangoleosa and Camellia Drupifera are projected to expand their range, particularly in higher latitudes, while Camellia Oleifera and Camellia Reticulata are expected to experience range contraction. The shifting of suitable ranges in different directions and over various distances for each species underscores their distinct ecological needs and adaptability​​.

The Future Distribution of Camellia Oilseed Species

In the future, the persistent suitable areas for these species will be spread across different regions of southern China. Camellia Chekiangoleosa’s persistent areas are expected to be in the middle and lower reaches of the Yangtze River. At the same time, Camellia Drupifera will find stability in the south of the Nanling mountains. Camellia Oleifera, the most widespread of the four, will retain most of its suitable areas in southern China, excluding some southwestern regions. Camellia Reticulata’s stable habitat will be in southwestern China, particularly Yunnan and its neighbouring provinces​​.

Conclusion: Adapting to Change for Sustainable Cultivation

This insight into the future distribution of Camellia oilseed species under changing climatic and land use conditions is invaluable. It not only aids in the strategic selection of sites for oil tea plantations but also contributes to the conservation of these vital species. As we look forward, understanding and adapting to these changes will be essential for the sustainable cultivation and conservation of Camellia oilseed species.
